A 2-column table with 2 rows. Column 1 is labeled x with entries negative 7, 0. Column 2 is labeled y with entries 0, 1.

Gre4nikov [31]

Answer:

1/7.

Step-by-step explanation:

To solve this, we can simply use an equation to solve for the slope using two points:

$m= \frac{y_{2}-y_{1} }{x_{2}-x_{1}}$ We can substitute our points giving us:

$m= \frac{1-0}{7-0}$ $= m= \frac{1}{7}$

The slope of the graph is 1/7!

A normal distribution has a mean 20 and standard deviation 5. What is the z score that corresponds to the value x=222

sashaice [31]

Answer: The z score that corresponds to the value x=22 is 0.4 .

Step-by-step explanation:

Given : A normal distribution has a mean 20 and standard deviation 5.

i.e. $\mu=20$

$\sigma=5$

Let x be the random selected variable.

We know that to find the z-score corresponds to the value x is given by :-

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

For x = 22, we have

$z=\dfrac{22-20}{5}=\dfrac{2}{5}\\\\\Rightarrow\ z=0.4$

Hence, the z score that corresponds to the value x=22 is 0.4
