(b)Complete each proportion.

Answer:

(−∞,∞)

Step-by-step explanation:

The answer to this question is 0.6826, or 68.26%. To calculate this probability, we need to use the z-score formula.

The z-score formula is a statistical measurement that is used to identify how far a raw score is from the mean score of a population. It is calculated by subtracting the population mean from an individual raw score and then dividing the difference by the population standard deviation.

This formula allows us to convert a given value into a standardized score relative to the mean and standard deviation of the normal distribution. In this case, the z-score for 27.42 is -1 and the z-score for 34.08 is 1.

We can then use the cumulative normal distribution function to calculate the probability of x being between 27.42 and 34.08. This function allows us to calculate the area under the normal distribution curve between two given points. Since the normal distribution is symmetrical, the area under the curve between -1 and 1 is 0.6826 or 68.26%. This is the probability of x being between 27.42 and 34.08.

To summarize, in order to calculate the probability of x being between 27.42 and 34.08, we need to calculate the z-scores of these two values and then use the cumulative normal distribution function to calculate the area under the curve between the two z-scores. The area under the curve between -1 and 1 is 0.6826 or 68.26%, which is the probability of x being between 27.42 and 34.08.

For the given function the intercepts are:

x-intercept: x = -4

y-intercept: y = 12.

Here we have a table that defines a function, and we want to find the intercepts of said function.

We can assume it is linear, then the slope of the function will be given by:

a = (9 - 3)/(-1 + 3) = 6/2 = 3

The linear function is like:

y = 3x + b

To find the value of b we can replace the values of the last point on the table, x = 2 and y = 18.

18 = 3*2 + b

18 = 6 + b

18 - 6 = b = 12

The linear function is:

y = 3x + 12

The x-intercept is the value of x when y = 0

0 = 3*x + 12

-12 = 3x

-12/3 = x = -4

And the y-intercept is the value of y when x = 0.

y = 3*0 + 12

According to given information, A is 50 years old and B is 10 years old.

In mathematics, an expression is a combination of numbers, variables, and mathematical operations (such as addition, subtraction, multiplication, and division) that can be evaluated to produce a numerical result or a value.

Let's use algebra to solve the problem.

Let A's current age be x, and B's current age be y.

From the problem, we know that:

x = 5y (A is five times as old as B)

x + 10 = 3(y + 10) (After 10 years, A will be 3 times as old as B)

We can use the first equation to substitute x in the second equation:

5y + 10 = 3(y + 10)

Simplifying this equation gives:

5y + 10 = 3y + 30

2y = 20

y = 10

So B is currently 10 years old. We can use the first equation to find A's current age:

x =5y = 5(10) = 50

So A is currently 50 years old.

Therefore, according to given information, A is 50 years old and B is 10 years old.

The time needed for the sample size to double is given as follows:

26.3 hours.

The exponential function that models the sample size after t hours is given as follows:

y(t) = y(0)e^(0.0264t).

The parameter y(0) represents the initial population, hence when the population is doubled, we have that:

y(t) = 2y(0).

Then we must solve the exponential function for the variable t, applying the natural logarithm, which is the inverse of the exponential, as follows:

2y(0) = y(0)e^(0.0264t).

e^(0.0264t) = 2

0.0264t = ln(2)

The 9th term of the sequence is approximately 30.234.

In mathematics, a sequence is an ordered list of numbers or other mathematical objects, such as functions, matrices, or vectors. Each member of the sequence is called a term, and the position of each term in the sequence is identified by its index or subscript.

Looking at the given terms, we can observe that each term is less than the previous term and the difference between consecutive terms is decreasing. Therefore, the sequence is decreasing and the difference between consecutive terms is decreasing by a factor of 2 each time.

Using this pattern, we can find the common difference between consecutive terms as follows:

60 - 80 = -20

45 - 60 = -15

We see that the difference between consecutive terms decreases by a factor of 2 each time. Therefore, the next difference would be:

-15 / 2 = -7.5

So, the next term would be:

45 - 7.5 = 37.5

We can continue this pattern to find the 9th term as follows:

Term 1: 80

Term 2: 60

Term 3: 45

Pearl's mortgage payment would be $678.47 per month.

A mortgage is a type of loan that is used to finance the purchase of real estate, such as a house or a piece of land. When a person takes out a mortgage, they borrow money from a lender (usually a bank or other financial institution) to buy the property, and they agree to pay back the loan over a set period of time, typically 15 to 30 years.

In the given question,

To calculate Pearl's mortgage, we need to first determine the amount of her down payment.

Down payment = 10% x $130,000

Down payment = $13,000

The amount that Pearl needs to finance with her mortgage is:

$130,000 - $13,000 = $117,000

To calculate the mortgage payment, we can use the formula for a fixed-rate mortgage:

Mortgage Payment = P * r * (1 + r)^n / ((1 + r)^n - 1)

Where:

P = Principal (amount borrowed)

r = Monthly interest rate (annual rate divided by 12)

n = Number of monthly payments (30 years x 12 months per year)

Monthly interest rate = 6.3% / 12 = 0.00525

Number of monthly payments = 30 years x 12 months = 360

Using these values, we can calculate the monthly mortgage payment:

Mortgage Payment = $117,000 * 0.00525 * (1 + 0.00525)^360 / ((1 + 0.00525)^360 - 1)

Mortgage Payment = $678.47 (rounded to the nearest cent)

Therefore, Pearl's mortgage payment would be $678.47 per month.

Correct option is B, modification that can be made to this loan to make it a viable option, given Giselle's situation Change the interest to 5.5%.

Giselle may either lower the interest rate to 5.5% or increase the down payment to 18% down in order to make the 20% down, 30-year fixed loan option financially feasible. Giselle's maximum monthly payment of $746.50 is exceeded by the monthly payment for the current loan option. The monthly payment would rise if the loan was shortened to 15 years, rendering it unprofitable. As a result, Giselle should choose a mortgage with a lower interest rate or put more money down in order to bring the monthly payment within her means.

Given Giselle's circumstances, the modification that may be made to this loan to make it an attractive alternative is to raise the interest rate to 5.5%.

Changes to the loan that will be made:

Price of acquisition: $163,000

Monthly income equals $2,986

25% of people are unwilling to spend money.

$33,000 is the down payment.

20% decline rate

Analysis

163,000 less $33,000 is the balance of the loan.

Amount remaining on loan is $130,000.

Condo loan balance = $163,000.20

Condo loan balance = $32,600

Down rate increase equals $163,000 x 20.25%

A higher down payment equals $33,007.50

The optimal solution, based on the research above, is to change the interest rate to 5.5% because it will result in a lower overall payment cost and make the loan amount a viable option.

A coordinate is a number that indicates the position of a point in a space or plane. In mathematics, we often use a coordinate system to represent points and their positions. A coordinate system is a system that uses one or more numbers or coordinates to uniquely determine the position of a point or an object in a space or plane. The most common coordinate system is the Cartesian coordinate system, which is named after the mathematician René Descartes. In the Cartesian coordinate system, each point is represented by an ordered pair of numbers (x, y), where x is the horizontal coordinate or abscissa, and y is the vertical coordinate or ordinate. The point (0, 0) is called the origin, and it represents the point where the x and y axes intersect. Coordinates can also be expressed in three or more dimensions, using three or more numbers. In three-dimensional space, the coordinates of a point are represented by an ordered triple (x, y, z), where x, y, and z are the horizontal, vertical, and depth coordinates, respectively.

Here,

The distance formula is used to find the distance between two points in a coordinate plane. In this case, we are finding the distance from the center of the habitat (x1, y1) to the point (x2, y2), so the formula becomes:

The 440-yd race is longer than the 400-m race by 2.336 meters.

Step-by-step explanation:

We can convert the distance of the 440-yd race to meters using the conversion factor 1 yd = 0.9144 m:

440 yd = 440 x 0.9144 m/yd = 402.336 m

Therefore, the 440-yd race is 402.336 meters long.

On the other hand, the 400-m race is already in meters.

Comparing the two distances, we can see that the 440-yd race is longer than the 400-m race.

To find out by how much longer, we can subtract the length of the 400-m race from the length of the 440-yd race:

402.336 m - 400 m = 2.336 m
