The scale on a map is 1 inch = 14 miles. The measurement between two cities on the map is 7 inches. What is the distance between the two cities?

Answers

Given:

The scale on a map is 1 inch = 14 miles.

The measurement between two cities on the map is 7 inches.

To find:

The actual distance between the two cities.

Solution:

We have,

1 inch = 14 miles

Multiply both sides by 7.

7×1 inch = 7×14 miles

7 inch = 98 miles

The measurement between two cities on the map is 7 inches and using the given scale, we get 7 inch = 98 miles.

Therefore, actual distance between the two cities is 98 miles.

If the quadratic parent function is reflected in the y-axis and vertically compressed by a factor of 1⁄2, write an equation to represent the new function.

Answers

Answer:

h(x) = 1/2f(-x)

Step-by-step explanation:

Let the parent function be:

f(x)

Reflection over y-axis:

g(x) → f(-x)

Vertical compression by a factor of 1/2:

h(x) → 1/2g(x)

Final function in terms of parent function:

h(x) = 1/2f(-x)

if 1/5 of the length of a pole is 12 feet, what is height of the pole?​

Answers

Answer:

60 feet

Step-by-step explanation:

if 1/5 is 12 feet of the length of the pole then that means you would have to multiply 12 by 5 to get 60.  1/5 +  1/5 + 1/5 + 1/5 + 1/5 is the height of the pole so you would have to multiply 1/5 (12) by 5 to get the full length of the pole.

Answer:

60ft

Step-by-step explanation:

if 1/5 of the pole is equal to 12ft then to find the total height (length) of the pole you need to multiply by the denominator (base of the fraction) so...

5 x 12 = 60ft

A bank's loan officer rates applicants for credit. the ratings are normally distributed with a mean of 200 and a standard deviation of 50. if an applicant is randomly selected, find the probability of a rating that is between 200 and 275.

Answers

Answer:

0.4332 = 43.32% probability of a rating that is between 200 and 275.

Step-by-step explanation:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

A bank's loan officer rates applicants for credit. the ratings are normally distributed with a mean of 200 and a standard deviation of 50

This means that [tex]\mu = 200, \sigma = 50[/tex].

Find the probability of a rating that is between 200 and 275.

This is the pvalue of Z when X = 275 subtracted by the pvalue of Z when X = 200. So

X = 275

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{275 - 200}{50}[/tex]

[tex]Z = 1.5[/tex]

[tex]Z = 1.5[/tex] has a pvalue of 0.9332

X = 200

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{200 - 200}{50}[/tex]

[tex]Z = 0[/tex]

[tex]Z = 0[/tex] has a pvalue of 0.5

0.9332 - 0.5 = 0.4332

0.4332 = 43.32% probability of a rating that is between 200 and 275.
