What is the slope of D and E??

Mazyrski [523]

Answer:

-4 and 0

Step-by-step explanation:

Rise over Run would give us the slope.

In the first graph, It goes down 4 while it goes 1 to the right.

This means that -4/1 = -4.

The second graph does not go up or down, meaning 0, while it goes 1 to the right.

This means that 0/1 = 0.

Gnoma [55]

Answer:

The proportion of individuals score at most 74 points on this test is 70%.

Step-by-step explanation:

The complete question is:

Suppose that the scores on a reading ability test are normally distributed with a mean of 70 and a standard deviation of 8. What proportion of individuals score at most 74 points on this test? Round your answer to at least four decimal places.

Solution:

Let <em>X</em> represent the scores on a reading ability test.

It is provided that $X\sim N(70,8^{2})$ .

Compute the probability that an individuals score is at most 74 points on this test as follows:

$P(X\leq 74)=P(\frac{X-\mu}{\sigma}\leq \frac{74-70}{8})$

$=P(Z$

Thus, the proportion of individuals score at most 74 points on this test is 70%.
