THERMOMETER An outdoor thermometer claims to be accurate within
2 degrees Fahrenheit. One day, the thermometer reads 72°F.
a. Write an absolute value inequality that represents the possible actual
temperature t.
b. What is the range of possible actual temperatures?

Answer: To solve the inequality x − (5 − 3x) ≤ 2x − 1, we need to simplify it by first distributing the negative sign in front of the parentheses, and then combining like terms. This gives us:

x - 5 + 3x ≤ 2x - 1

4x - 5 ≤ 2x - 1

Next, we can isolate the variable on one side of the inequality by subtracting 2x from both sides:

4x - 2x - 5 ≤ -1

2x - 5 ≤ -1

Finally, we can isolate x by adding 5 to both sides and dividing by 2:

2x ≤ 4

x ≤ 2

So the solution to the inequality is x ≤ 2.

To graph this solution on a number line, we can put a closed dot at 2 and shade to the left of it, since all values less than or equal to 2 satisfy the inequality. Therefore, the correct graph is A, a number line with a closed dot at 2 shaded to the left.

18x + 22y

Step-by-step explanation:

4x (3) + 5y (3) + 2x (3) + 7y

Multiply the coefficients of the variables x and y with the constants, so that:

4x (3) + 5y (3) + 2x (3) + 7y

= 12x + 15y + 6x + 7y

Then just add up the coefficients with the same variable:

12x + 6x = 18x

15y + 7y = 22y

So the final answer is:
18x + 22y

The area of one slice of a large pizza with a diameter of 24 inches is 56.52 square inches.

The formula for calculating the area of a circle is A = πr^2, where A is the area of the circle, π is the constant pi (3.1415) and r is the radius of the circle. To calculate the area of a slice, we must first calculate the radius of the pizza. To do this, we divide the diameter of the pizza (24 inches) by 2, which yields a radius of 12 inches.

Now that we have the radius, we can calculate the area of one slice. Plugging the radius of 12 inches into the equation, we get A = 3.1415*12^2 = 452.16 square inches. Since each pizza is cut into 8 equal slices, each slice would have an area of 452.16/8 = 56.52 square inches.

The slope of the line that passes through the points (6,10) and (6,−2) is undefined.

The slope of a line is defined as the ratio of the vertical change (rise) to the horizontal change (run) between any two points on the line. In mathematical terms, the slope of a line passing through two points (x₁, y₁) and (x₂, y₂) is given by the formula:

slope = (y₂ - y₁) / (x₂ - x₁)

Now, let's apply this formula to the given points (6, 10) and (6, -2). Here, x₁ = 6, y₁ = 10, x₂ = 6, and y₂ = -2. Substituting these values in the formula, we get:

slope = (-2 - 10) / (6 - 6)

Notice that the denominator is zero, which means that the line is a vertical line. In this case, the slope is undefined.

Step-by-step explanation:

There are four numbers: 8, 15, 100 and 123.

Number is a mathematical object used to count, measure, and label. It is used in many different contexts, from everyday life to scientific research. Numbers can be represented in various forms, such as symbols, digits, and words. They are used to represent quantities, distances, time, and other concepts. Numbers can also be used to represent relationships, such as equations, which are statements that describe how two or more things are related.

To solve this problem, it is best to line the numbers up on the y axis or x axis. To multiply the numbers, start by multiplying the numbers on the y axis first. So, 8 x 15 = 120. Then, multiply the result by the number on the x axis which is 100. 120 x 100 = 12,000. Finally, multiply 12,000 by the last number on the x axis which is 123. 12,000 x 123 = 1,476,000. Therefore, the answer to the problem is 1,476,000.

A linear equatiοn is an equatiοn οf a straight line in twο variables, usually written in the fοrm y = mx + b, where m is the slοpe and b is the y-intercept. It represents a relatiοnship between twο variables that is linear, meaning that as οne variable changes, the οther changes at a cοnstant rate.

Let's use algebra tο sοlve the prοblem.

Let x be the number οf hamburgers sοld οn Saturday.

Then, accοrding tο the prοblem, the number οf cheeseburgers sοld οn Saturday is 73 mοre than the number οf hamburgers sοld, sο the number οf cheeseburgers sοld is x + 73.

The prοblem alsο tells us that the tοtal number οf hamburgers and cheeseburgers sοld is 523. Sο we can set up an equatiοn:

x + (x + 73) = 523

Simplifying the left side οf the equatiοn:

2x + 73 = 523

Subtracting 73 frοm bοth sides:

2x = 450

Dividing bοth sides by 2:

x = 225

we can deduct that the angle on the L vertex is 25°, because that way all three angles will result in 180°.

We know that JKLM is a parallelogram, which means that its opposite sides are parallels, such that: JK // ML and JM // KL.

So, we know that the angle MLJ equals 25°, and JK // ML, from this we can say that angles LJK and MLJ are equal, because they are ''internal alternate angles'', since that they are inside the parallels.

So, angle LJK is 25, and JKL is a triangle, which has the angle at K vertex equal to 130°. We know that internal angles in a triangle must sum 180°.

Since that, two angles, in the triangle JKL, measure 130° + 25° = 155°; we can deduct that the angle on the L vertex is 25°, because that way all three angles will result in 180°.

The following are the two-sided (symmetrical) confidence intervals with a 95 percent confidence level for the expected value of the weight:Option a) Sample size 13:For a sample size of 13, the standard error of the mean is calculated as follows:SE = σ/√nwhere SE is the standard error, σ is the variance, and n is the sample size.In this case, SE = √(0.64)/√(13) = 0.1772.The t-distribution should be used to calculate the confidence interval since the population's standard deviation is unknown.The t-value corresponding to the 95% confidence interval with 12 degrees of freedom (df = n – 1) is 2.179.

(a) To solve the differential equation DP/dt = kPcos(rt-[tex]\theta[/tex]),

The variables can be split apart and integrat:

∫(1/P) dP = ∫k cos(rt-[tex]\theta[/tex] ) dt

ln|P| = (k/r)sin(rt- [tex]\theta[/tex] ) + C

where

C is the constant of integration.

By solving for P, we get:

We can determine the value of C by using the initial condition P(0) = P0:

P(0) = [tex]e^{(k/r sin(- \theta) + C)}[/tex]= P0

C = ln(P0) - (k/r)sin(-[tex]\theta[/tex] )

C = ln(P0) + (k/r)sin([tex]\theta[/tex] )

To calculate a rate, divide two quantities with different units; to calculate a unit rate, divide a rate by the quantity being measured.

What is rate ?

In mathematics, a rate is a ratio that compares two quantities with different units. It is typically expressed as the amount of change of one quantity with respect to another quantity. Rates are often used in the context of describing how quickly or slowly something changes over time or space.

To calculate a rate, we need to divide two quantities that have different units. For example, if we want to find the rate of a car's speed, we divide the distance traveled (in miles) by the time taken to travel that distance (in hours).

The formula for rate is:

rate = quantity / time

To calculate a unit rate, we need to divide a rate by the quantity being measured. For example, if the rate is the number of miles traveled per hour, the unit rate would be the number of miles traveled in one hour. To find the unit rate, we divide the rate by 1 hour.

The formula for unit rate is:

unit rate = rate / 1

When calculating rates or unit rates, it is important to make sure that the units of the quantities being divided are consistent. If the units are not the same, we need to convert them to the same unit before performing the division.

Therefore, to calculate a rate, divide two quantities with different units; to calculate a unit rate, divide a rate by the quantity being measured.

The price per unit that yields maximum revenue is $400.

We can start by finding the demand function for the product. Since the demand is assumed to be linear, we can use two data points to find the equation of the line:

(40, 300) and (45, 275)

Using the point-slope form of a line, we get:

(275 - 300) / (45 - 40) = -5/25 = -1/5

y - 300 = (-1/5)(x - 40)

y = (-1/5)x + 320

where y is the number of units sold per week and x is the price per unit.

The revenue function is simply the product of the price and the number of units sold:

R = xy

Substituting the demand function, we get:

R = x(-1/5)x + 320x

Simplifying, we get:

R = -1/5x^2 + 320x

To find the price per unit that yields maximum revenue, we need to take the derivative of the revenue function with respect to x and set it equal to zero:

dR/dx = -2/5x + 320 = 0

The y-intercept of the graph is located at (0, 0). So, the value of c is 0.

What is graph?

A graph is a visual representation of data that displays the relationship between two or more variables. It consists of a set of points, called vertices or nodes, which are connected by lines or curves, called edges or arcs. The vertices represent the variables, while the edges represent the relationship between them.

To find the y-intercept of the graph of y = -7x + 140y, we need to substitute x = 0 into the equation and solve for y. This will give us the y-coordinate of the point where the graph intersects the y-axis.

Substituting x = 0, we get:

y = -7(0) + 140y

y = 140y

Simplifying the equation, we get:

139y = 0

Dividing both sides by 139, we get:

A's cardinality is equivalent to its element count if A has a finite amount of elements. Say |A|=5 if A=2, 4, 6, 8, 10. The outcome of a numbering process is referred to as "cardinality". A set's cardinality is determined by the number of components in it. For illustration, the group 1, 2, 3, 4, and 5 has a greater cardinality of five than the set 1, 2, 3, and 5, each of which has an attributes of three.

Here,

a)

I "Chinese New Year of 2023" has one cardinal element, making it one-dimensional.

ii) Since there are three elements in S and each element can either be included in a subset or not, the power set P(S) of S=1,,apple has 23 = 8 elements.

iii) xRx2=3 has two components because the squares of two real numbers, 3 and -3, are both 3.

iv) Since "0" is regarded as one element and there are five other distinct elements in the collection,  {{0,1,2},3,4,5,∅,{{0}}}  has six elements.

b)
