To convert this X score to Z score we use the formula given below
Here we know all the values of x, mu and sigma
Just substitute
Z score
=
Thus Z score of Brenda is 0.5

Y=-5x +8
y=mx+b
The slope is rise over run, you can use the points on there to determine detla y/ delta x. Then the b is the y intercepts, which is where the function passes the y axis.
Answer:
0.11
Step-by-step explanation:
To get the probability above, we simply look for the events greater than 4, then add their probabilities
That is;
P(5) + P(6) + P(7)
So the probability in this case will be;
0.07 + 0.03 + 0.01 = 0.11
Answer:
im nt quite sure lets wrok it out
