Hi there, Kevin's age would be C. 7. This is because Tonya right now is 14. 7 is half of 14.
I think it must be 87 .
Step-by-step explanation:
Not sure how to explain.
Answer:
0.8808
Step-by-step explanation:
The objective is to calculate the probability of:
P(-1.20 ≤ z ≤ 2.64)
i.e. the probability that is the area between two z-values.
Thus;
P(-1.20 ≤ z ≤ 2.64) = P(z ≤ 2.64) - P( z ≤ 1.20)
From z table;
P(-1.20 ≤ z ≤ 2.64) = 0.9959 - 0.1151
P(-1.20 ≤ z ≤ 2.64) = 0.8808
We can see the shaded area under the standard normal curve from the image attached below.
Answer:
negative 64.8
Step-by-step explanation:
Negative 64.8 comes before negative 80 so that makes it greater in terms of negatives.
Sorry if I'm wrong though
