Z-test should be used when the parent standard deviation is known and the sample size is greater than or equal to 30 (to satisfy the Central Limit Theorem). A T-test should be used when these two rules do not apply.
4 over 3 in number form is 1.33333333333

Answer:
f=1/40
Step-by-step explanation:
5f=1/8
f=(1/8)/5
f=(1/8)(1/5)
f=1/40
Answer:
∠Z and ∠W are supplementary
Step-by-step explanation:
In the diagram given showing a special trapezoid, WX and ZY are two opposite sides that are parallel to each other.
Thus, consecutive angles would be supplementary.
Therefore, the only correct option that is true is:
∠Z and ∠W are supplementary.
The test options are incorrect as consecutive angles are not complementary and they are not in themselves congruent to each other.
