Answer: The graph becomes narrower

<u>Step-by-step explanation:</u>

The vertex form of a quadratic equation is: y = a(x - h)² + k where

|a| represents the vertical stretch if |a| > 1, vertical shrink if |a| < 1
(h. k) represents the vertex

A vertical stretch means the curve gets narrower.

A vertical shrink/compression means the curve gets wider.

MA/MN = MB/BP

MA = 46.2 -14
MA=32.2

so
MA/MN = MB/BP
32.2/46.2=x/72.6
46.2x = 72.6 * 32.2
46.2x = 2337.72
x = 2337.72 / 46.2
x = 50.6

The mean speed of vehicles along a stretch of highway is 56 mph with a standard deviation of 4 mph. You

Elenna [48]

The corresponding z score for speed of 62 mph, 47 mph, and 56 mph is 1.5, -2.25 and 0 respectively.

<h3>Z score</h3>

Z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:

$z=\frac{x-\mu}{\sigma }$

Where x is raw score, μ is mean, σ is standard deviation

Given that:

σ = 4, μ = 56, hence

for x = 62:

$z=\frac{62-56}{4 } =1.5$

for x = 47:

$z=\frac{47-56}{4 } =-2.25$

for x = 56:

$z=\frac{56-56}{4 } =0$

The corresponding z score for speed of 62 mph, 47 mph, and 56 mph is 1.5, -2.25 and 0 respectively.
