Using translation concepts, it is found that there was a horizontal compression of the function.

<h3>What is a translation?</h3>

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

In this problem, there was a multiplication in the domain of the function, by a factor greater than 1, hence there was a horizontal compression of the function.

Suppose that the speeds of cars travelling on California freeways are normally distributed with a mean of 61 miles/hour. The hig
cricket20 [7]

Answer:

The standard deviation of the speeds of cars travelling on California freeway is 6.0088 miles per hour.

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}

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 This p-value is the probability that the value of the measure is greater than X.

In this problem, we have that:

Suppose that the speeds of cars travelling on California freeways are normally distributed with a mean of 61 miles/hour. This means that \mu = 61.

The highway patrol's policy is to issue tickets for cars with speeds exceeding 75 miles/hour. The records show that exactly 1% of the speeds exceed this limit. This means that the pvalue of Z when X = 75 is 0.99. This is Z = 2.33

So

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

2.33 = \frac{75 - 61}{\sigma}

2.33\sigma = 14

\sigma = \frac{14}{2.33}

\sigma = 6.0088

The standard deviation of the speeds of cars travelling on California freeway is 6.0088 miles per hour.

Please answer and explain.
loris [4]

Answer:

Brock is lying.

Step-by-step explanation:

Brock is lying because  4^-2 = 1/4^2 =  1/16 of a  second!! (He'd have to hold on to a rocket to do 100 meters in that time!!).

Jim's time of 4^2 = 16 seconds is believable.
