Answer: 1.83
Step-by-step explanation:
Z = (x - mean) / standard deviation
= (97-75) / 12
= 22/12 = 11/6 = 1.83
Answer:
The second one.
Step-by-step explanation:
Answer:
P(A and B) = 0.1 = 10%
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is

In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question, we have that:

What is P(A and B)?


P(A and B) = 0.1 = 10%
Answer:
y=-6/2x+2
Step-by-step explanation:
y=mx+b
x1 y1 x2 y2
(1,2) (3,-4)
y2-y1/x2-x1
-4-2= -6
3-1= 2
slope= -6/2
What? Need answers. Plus, I can tell that your are doing this in class. Bad idea.
