a) z = -1.645
b) z = 0.674
Step-by-step explanation:
We have to find the value of z of a standard normal variable Z that satisfies each of the following conditions.

Calculation the value from standard normal z table, we have,
b) 25% of the observations fall above z
Calculation the value from standard normal z table, we have,
Answer:

Step-by-step explanation:
If you would like to find the area of the base of the fountain, you can calculate this using the following steps:
1 2/3 ft * 2 2/3 ft = 5/3 * 8/3 = 40/9 = 4 4/9 square feet
The area of the base of the fountain is 4 4/9 square feet.
Explanation:
We can rewrite the expression:
√8×√20
using the following rule for radicals:
√a⋅√b=√a⋅b
√8⋅√20⇒√8⋅20⇒√160
Now, we can use this rule for radicals to simplify the radical:
√a⋅b=√a⋅√b
√160⇒√16⋅10⇒√16⋅√10⇒4√10
