Answer:

the sales tax rate is 8.59%

Step-by-step explanation:

The computation of the sales tax rate is as follows:

= Tax value ÷ Total taxes

= $10.80 ÷ ($150.52 - $24.72)

= $10.80 ÷ $125.80

= 8.59%

Hence, the sales tax rate is 8.59%

We simply applied the above formula to determine the sales tax rate

Answer:

  -130.8

Step-by-step explanation:

The average of the two slope values is ...

  (-148.8 -112.8)/2 = -261.6/2 = -130.8

The slope of the tangent line at t=15 is approximately -130.8.

In 2014, the CDC estimated that the mean height for adult women in the U.S. was 64 inches with a standard deviation of 4 inches.
Vladimir79 [104]

Answer:

A. 16%

Step-by-step explanation:

Problems of normally distributed samples can be solved using the z-score formula.

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

Z = \frac{X - \mu}{\sigma}

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.

In this problem, we have that:

\mu = 64, \sigma = 4

Which of the following gives the probability that a randomly selected woman has a height of greater than 68 inches?

This is 1 subtracted by the pvalue of Z when X = 68. So

Z = \frac{X - \mu}{\sigma}

Z = \frac{68 - 64}{4}

Z = 1

Z = 1 has a pvalue of 0.84.

1 - 0.84 = 0.16

So the correct answer is:

A. 16%
