Answer:

the value of the z is -3.5

Step-by-step explanation:

According to the question, the following information is given

-2z - 7

Based on the above information

We assume that we have to determine the z value

-2z - 7 = 0

-2z = 7

z = 7 ÷ -2

= -3.5

Hence, the value of the z is -3.5

The polygon is concave because if you placed lines directly on top of every side of the polygon, one or more of the lines would intersect an existing side. In a convex polygon, if you placed lines on top of the sides they wouldn't intersect another side.

So your answer is B) Concave.

Solve the problem. For a standard normal distribution, find the percentage of data that are between 3 standard deviations below

solong [7]

Answer:

83.85%

Step-by-step explanation:

We will use the empirical rule. For a standard normal distribution the mean is equal to 0 and the standard deviation is equal to 1. Then, between 3 standard deviations below the mean, we have 2.35% + 13.5% + 34% = 49.85% of data, and 1 standard deviation above the mean we have 34% of data. Therefore, the percentage of data that are between 3 standard deviations below the mean and 1 standard deviation above the mean is 49.85%+34% = 83.85%.
