Z- score is a statistical tool that is used to determine the probability of finding a number or a value under a normal distribution plot. A normal distribution assumes that the mean is equal to zero and that the standard deviation is equal to 1. Using the z-score table, we can find the probability either on the right side or the left side. Using the table hence, we find the probability to the left of the value. The probability that is equivalent to the unknown z should be equal to 0.5 + (0.27/2) = 0.635. 0.5 comes from the assumption that the area under the curve on each side is 50% of the total. The equivalent z score is equal to z = 0.345.

The answer is D.
Step-by-step explanation:
She forgot to find the square root of 7225.
For applies= associative and distributive
and for doesnt apply = commutative.
im not 100 sure for the distributive answer but ik the other ones are right
Answer:
A, Yes, he has 1 cup left
Step-by-step explanation:
5.25 at the start
5.25 - 3.5 = 1.75
1.75 + 2 = 3.75
3.75 - 2.75 = 1
You need to draw out the triangle and then use the rules of a right triangle with tangent because you have the opposite side and you are trying to find the adjacent side.
