Answer:
a) 22e^-0.01t kilograms
b) about 19.906 kilograms
Step-by-step explanation:
You want an equation for the amount of salt in a 15 kL brine tank initially containing 22 kg of salt if 150 L/min of the contents is replaced by pure water.
(a) Remaining saltThe quantity of salt s(t) in kilograms can be described by the differential equation ...
s(0) = 22; s'(t) = -150/15000·s(t)
The solution can be found by separation of variables.
[tex]\displaystyle\dfrac{ds}{dt}=-0.01s\\\\\int{\dfrac{1}{s}}\,ds=-0.01\int{}\,dt\\\\\ln{s}=-0.01t+c_1\\\\s=c_2\cdot e^{-0.01t}\qquad\text{where $c_2$ is $s(0)=22$}\\\\\boxed{s(t)=22e^{-0.01t}}[/tex]
(b) s(10)The amount of salt remaining after 10 minutes is ...
s(10) = 22·e^(-0.01·10) = 22·e^-0.1
s(10) ≈ 19.906 . . . . kilograms
There is about 19.906 kg of salt in the tank after 10 minutes.
__
Additional comment
The initial rate of change of the amount of salt is -22/100 kg/min, so after 10 minutes, we expect an approximate reduction by 2.2 kg to 19.8 kg. Since the rate slows as salt is removed, the value 19.9 kg after 10 minutes is reasonable.
There are a couple of places where the integration constant can be put in the equation for the salt quantity. As a multiplier of the exponential function, its value is found in a straightforward way.
Consider the expression (x2−9)(x+4). Select all the values of x for which (x2−9)(x+4)=0
Answer:
X= 567890
Step-by-step explanation:
Answer:
See below, please.
Step-by-step explanation:
Using the zero product property, we can set each factor equal to zero and solve for x:
(x² - 9)(x + 4) = 0
(x² - 9) = 0 or (x + 4) = 0
For the first factor, we can factor it further as the difference of squares:
(x + 3)(x - 3) = 0
So, either (x + 3) = 0 or (x - 3) = 0, giving us:
x = -3, x = 3, or x = -4
Therefore, the values of x for which (x² - 9)(x + 4) = 0 are -3, 3, and -4.

A typical equation has one or more variables, which are often denoted by letters and have a range of possible values. Equations are frequently used in a variety of fields to describe relationships between distinct numbers or to address issues. For instance, the equation x + 2 = 5 only has one variable, x. It denotes that the product of x and 2 equals 5.
given
We can represent 556 as a rectangle with length 556 and width 1, and 16 as a rectangle with length 16 and width 1 to calculate the quotient of 556 and 16 using an area model.
This is how it goes:
To start, we deduct 16 from 556 to obtain:
556 - 16 = 540
540 = 16 x 33 + 4
Finally, by multiplying the numerator and denominator of the fraction 33 4/16 by 4, we may express the quotient of 556 and 16 as a mixed number in the simplest form, which results in:
556 ÷ 16 = 33 4/16 = 33 1/4
The product of 556 and 16 is therefore 33 1/4 as we express the quotient of 556 and 16 as a mixed number in the simplest form.

if a continuous probability distribution is symmetric above and below the mean and displays a bell-shaped function, what type of distribution does this indicate?
There is a 68.26% chance of a value falling between 3 and 7 in the given normal distribution.
This indicates a normal distribution, which is a type of continuous probability distribution. It is characterized by a bell-shaped curve that is symmetric about the mean, with a specific formula given by f(x) = [tex]1/(σ√2π)e^(-(x-μ)^2/2σ^2)[/tex]where μ is the mean, σ is the standard deviation, and x is the random variable.
In terms of calculation, we can use the formula to calculate the probability of a certain event occurring. For example, if we know the mean and standard deviation of a normal distribution, we can calculate the probability of a value between two given points. For example, if the mean is 5 and the standard deviation is 2, then the probability of a value between 3 and 7 is given by the integral of f(x) from 3 to 7, which is equal to 0.6826. This means that there is a 68.26% chance of a value falling between 3 and 7 in the given normal distribution.

50 Points!!! Are the Factor Theorem and Synthetic Division the same? If not, explain the difference.
Answer:
The Factor Theorem and Synthetic Division are not the same. The Factor Theorem states that if a polynomial f(x) has a root c, then x - c is a factor of f(x). Synthetic Division is a way of dividing a polynomial by a binomial.
Step-by-step explanation:
To use Synthetic Division, you first need to find the coefficients of the polynomial. Then, you set up the synthetic division table with the binomial on top and the coefficients of the polynomial on the bottom. Starting with the first coefficient, you multiply it by the first term of the binomial and write the product below the coefficient. Then, you add the two numbers below the product and write the sum below that. Continue until you reach the end of the binomial. The remainder at the bottom of the table is the remainder when f(x) is divided by x - c.
If the remainder is 0, then x - c is a factor of f(x).

g inspect the bball3 data set. what structure do these data appear to take? panel data cross sectional time series
The bball3 dataset appears to take the form of panel data, which is a type of longitudinal data consisting of multiple observations of the same individuals over time
The bball3 dataset appears to take the form of panel data. Panel data is a type of longitudinal data where observations are made on the same individuals over time. This means that the dataset likely consists of multiple observations of a set of individuals, with the observations collected at different points in time. In a panel data set, each individual can be referred to as a ‘panel unit’.
Cross-sectional data, on the other hand, consists of observations that are collected only once, at a single point in time. This means that each observation consists of a snapshot of the population at a given moment, which is different from panel data where each observation may represent different points in time for the same individuals.
Time series data is a type of data that is collected over a period of time. It captures how a certain variable changes over time, and is often used for forecasting purposes. This is different from panel data, which captures information about the same individuals at different points in time.
In conclusion, the bball3 dataset appears to take the form of panel data, which is a type of longitudinal data consisting of multiple observations of the same individuals over time. It is not cross-sectional or time series data.

what is the slope of the line of best-fit in the scatterplot below?on a graph, a trend line goes through points (3, 12) and (6, 19).
The slope of the line of best fit in the scatterplot below can be determined using the formula for the slope of a line:
Slope = (y2-y1)/(x2-x1)
In this case, x1 = 3, y1 = 12, x2 = 6, y2 = 19. So, the slope of the line of best fit is (19 - 12) / (6 - 3), which equals 7/3 or 2.33.
The line of best fit is the line that best represents the data on a scatterplot. It is the line that is closest to all the data points in the graph. The slope of the line of best fit helps to indicate whether the data points are moving in a positive or negative direction. If the slope is positive, the data points are increasing, and if the slope is negative, the data points are decreasing.
A positive slope, like the one in this example, means that as x increases, y also increases. This means that in this case, as the x-values (3 and 6) increase, the y-values (12 and 19) also increase.
The slope of the line of best fit can also be used to make predictions about values of y, given values of x. For example, if x = 8, then y = 26, because the slope of the line of best fit is 2.33, and 8*2.33 = 19.8, which is approximately equal to 26.
Overall, the slope of the line of best fit on this scatterplot is 2.33, which is a positive number. This indicates that as the x-values increase, the y-values also increase, and it can also be used to make predictions about y-values, given x-values.

we have data that is a continuous variable. it is a measurement of time between events. this is a situation where we should evaluate a histogram for a likely exponential distribution. group of answer choices true false
The statement "we have data that is a continuous variable. it is a measurement of time between events. this is a situation where we should evaluate a histogram for a likely exponential distribution" is true because when dealing with continuous data representing time between events, it is common to evaluate a histogram to determine if it follows an exponential distribution.
If the data represents the time between events and it is a continuous variable, it is common to evaluate the histogram to see if it follows an exponential distribution. The exponential distribution is often used to model the waiting time between independent events that occur at a constant average rate, and it has a continuous range of values that can be plotted as a histogram.
To evaluate whether the data follows an exponential distribution, you can plot a histogram and visually check if it has a single peak and a decreasing tail, which are characteristic of the exponential distribution. You can also use statistical tests such as the Kolmogorov-Smirnov test or the Anderson-Darling test to assess the goodness-of-fit between the data and the exponential distribution.

6. One hundred twenty-five townspeople were interviewed at random. Forty of the interviewed townspeople were from the middle school. The middle school has 800 students. Estimate the size of the town.
Answer:
See below, please.
Step-by-step explanation:
To estimate the size of the town, we can use a proportion.
Number of middle school students / Total town population = Number of interviewed middle schoolers / Total number of interviewed townspeople
Let x be the total town population. Then we have:
800 / x = 40 / 125
Simplifying this proportion, we get:
40x = 800×125
40x = 100000
x = 100000 / 40
x = 2500
Therefore, the estimated size of the town is 2500.What is the exact value of side x in the Trina for below? 20in 30 degree and X?
According to the question, the exact value of side x in the Trina are 34.641016151377546in.
What is value?Value is an intangible concept that refers to the worth of something, whether it is tangible or intangible. It is based on the perceived benefits and costs associated with the thing in question. Value can be subjective, as different people may place different worth on the same item. Value can also be objective, as there may be a set market price for a certain item.
The exact value of side x in the triangle can be determined by using the law of sines. The law of sines states that the ratio of the length of a side to the sine of its opposite angle is the same for all sides of a triangle.
Therefore, we can set up the following equation:
(20in/sin30°) = (x/sin60°)
Solving for x, we get:
x = 20in×(sin60°/sin30°)
x = 20in×(√(3)/1)

what is the smallest font size doug should use in the text on his slides? group of answer choices 20 points 24 points
The smallest font size that Doug should use in the text on his slides is 24 points.
The reason for this is that smaller font sizes can make the text difficult to read, especially from a distance.
According to industry standards, the recommended minimum font size for slide presentations is 24 points.
This is because smaller font sizes can be challenging to read, especially if the audience is sitting at the back of the room or if the slides are being viewed on a small screen.
While 20 points may seem like a reasonable font size, it's still small enough to make it difficult for some people to read the text.
Therefore, to ensure that all members of the audience can read the text on the slides, it's best to use a font size of at least 24 points.
In addition to using a larger font size, it's also essential to use a clear and legible font.
Sans-serif fonts such as Arial, Helvetica, or Calibri are recommended for presentations as they are easy to read, even from a distance.
It's also important to keep the contrast between the text and the background high to make it easier to read the text.

binomial a lottery will be held. from 1000 numbers, one will be chosen as the winner. a lottery ticket is a number between 1 and 1000. how many tickets do you need to buy in order for the probability of winning to be at least 50%?
we need to buy at least 694 tickets to have a probability of winning at least 50%.
We can use the binomial distribution formula to solve this problem. Let X be the number of tickets we need to buy to have a probability of winning at least 50%. Then:
P(X ≥ 1) ≥ 0.5
This means that the probability of winning with at least one ticket is at least 50%. We can find this probability using the complement rule:
P(X ≥ 1) = 1 - P(X = 0)
The probability of not winning with any ticket is:
P(X = 0) = (999/1000)^n
where n is the number of tickets we buy. Therefore:
1 - (999/1000)^n ≥ 0.5
Simplifying this inequality, we get:
(999/1000)^n ≤ 0.5
Taking the logarithm of both sides, we get:
n log(999/1000) ≤ log(0.5)
n ≥ log(0.5) / log(999/1000)
n ≥ 693.15

The shaded area in the decimal grid below represents the amount of money that Karla has. She plans on dividing the money evenly between her three younger brothers. Her brothers are planning to spend the money on pieces of candy that cost $0.10 each.
What will be the maximum number of pieces of candy that each brother can buy?
(The large square of the grid represents $1.00 and each small square represents $0.01.)
Karla's three brothers can buy a maximum of 4 pieces of candy if they divide the money evenly.
What is division?
Division is a mathematical operation that involves splitting a quantity into equal parts or groups. It is one of the four basic arithmetic operations, along with addition, subtraction, and multiplication. Division is denoted by the symbol "÷" or "/", and it is usually expressed as a fraction or a quotient.
To solve this problem, we need to determine the amount of money represented by the shaded region. Here are the steps:
Count the number of small squares in the grid. For example, if the grid has 10 rows and 10 columns, there are 100 small squares in total.Determine the value of each small square. For example, if the large square of the grid represents $1.00, each small square represents $0.01.Multiply the number of shaded cells by the value of each small square to find the total amount of money represented by the shaded region.Assuming that each small square represents $0.01 and there are 143 shaded cells, the total amount of money represented by the shaded region is:
143 cells x $0.01/cell = $1.43
Now, we need to divide $1.43 evenly among Karla's three brothers to find the maximum number of pieces of candy each brother can buy.
$1.43 ÷ 3 = $0.476666...
Since we cannot buy fractional pieces of candy, we need to round down to the nearest whole number. Therefore, each of Karla's three brothers can buy a maximum of:
$0.47 ÷ $0.10/piece = 4 pieces of candy
So each of Karla's three brothers can buy a maximum of 4 pieces of candy if they divide the money evenly.

To find out how much time June should work out each day to spend an even amount of time working out, we can first find the total amount of time she spent working out:
6/8 + 4/8 + 2/8 + 4/8 = 16/8 = 2 hours
Since there are four days she worked out, to find out how much time she should work out each day, we can divide the total time by four:

Therefore, June should work out for 0.5 hours, or 30 minutes, each day to spend an even amount of time working out.
the width of this rectangle is 1/3 of the length. Find the width of the rectangle
Answer:
length = 42 in , width = 14 in
Step-by-step explanation:
given the width is [tex]\frac{1}{3}[/tex] of the length , then
y - 4 = [tex]\frac{1}{3}[/tex] (2y + 6) ← multiply both sides by 3 to clear the fraction
3y - 12 = 2y + 6 ( subtract 2y from both sides )
y - 12 = 6 ( add 12 to both sides )
y = 18
then
length = 2y + 6 = 2(18) + 6 = 36 + 6 = 42 in
width = y - 4 = 18 - 4 = 14 in

Harold will drive 330 more miles at the same rate how long will it take care old to drive 330 miles
Assuming he drives at a speed of 60 miles per hour, it will take him 5.5 hours to drive the 330 miles.
How long does it takes him to drive the 330 miles?If Harold drives 330 more miles at the same rate of 60 miles per hour, we can use the formula:
distance = rate x time
Let t be the time in hours it takes to drive the additional 330 miles. Then we have:
330 = 60t
Solving for t, we get:
t = 330/60
t ≈ 5.5 hours

18.
x + x + 20 = 180
2x = 160
x = 80
Answer: x = 80°
y + y + 10 = 180
2y = 170
y = 85
Answer: y = 85°
Answer: x = 80° and y = 85°
Step-by-step explanation: In a cyclic quadrilateral, opposite angles add up to 180°.
x + (x + 20) = 180 and
y + (y + 10) = 180.
Solving for x
x + (x + 20) = 180
x + x + 20 = 180
2x = 180 - 20
2x = 160
2x/2 = 160/2
x = 80°
Solving for y
y + (y + 10) = 180
y + y + 10 = 180
2y = 180 - 10
2y = 170
2y/2 = 170/2
y = 85°
How much pure alcohol must a pharmacist add to 10cm^3 of a 8% alcohol solution to strengthen it to a 80% solution?
To create an 80% alcohol solution, the pharmacist must therefore mix 2.17 cm3 of pure alcohol with 10 cm3 of the 8% alcohol solution.
what is solution ?A value or combination of values that satisfy an equation or system of equations are referred to as solutions in mathematics. For instance, if we substitute x = 2 into the equation, we get 2(2) + 3 = 7, which is a true statement, hence the answer to the equation 2x + 3 = 7 is x = 2. Similar to this, an equation system may have one or more solutions that simultaneously fulfil every equation in the system. Finding answers to equations or systems of equations is a key component of many branches of mathematics and has significant applications.
given
Find out how much pure alcohol is now contained in the 8% solution to start.
An 8% alcohol solution in 10 cm3 contains:
There are 0.8 cm3 of pure alcohol in 0.08 x 10 cm3.
Let's now calculate the amount of pure alcohol that has to be added to achieve an 80% solution using the alligation method.
We must add pure alcohol to the solution to raise the concentration from 8% to 100%. In order to connect 100% to 8% in the left column, we place 100% in the right column. There is a 92% discrepancy between these two percentages.
We put 80% in the middle column because we aim to arrive at an 80% solution. Between 80% and 100%, there is a 20% difference.
Now, we may construct the subsequent equation:
20/92 = x/10
After finding x, we obtain:
