z = -2.83
<u>Explanation:</u>
Given:
Mean, μ = 68
Standard deviation, σ = 6
Data point, x = 51
Z score, z = ?
We know:

Substituting the value we get:

A negative z score says that the data point is below average.
Answer:
Ok so we are trying to find out how much flour she used to make brownies so we already know that she used 1/2 flour to make bread and She uses 1/8 flour less flour to make bread than to make cookies so if we add 1/2 and 1/8 we will get the amount of flour she used to make the cookies so 1/2 + 1/8 = 5/8 so now that we have the amount of flour she used to make the cookies we know that that is 1/4 more flour than brownies so if we subtract 5/8 by 1/4 we will get are answer to how much flour she uses to make brownies so 5/8 - 1/4 = 3/8 and that's your answer do you understand?

Answer:
9
Step-by-step explanation:
y = 0
y = 3(0)^2-6(0) + 9
y = 9
3=-2+B. +2 +3 B=5 “y=1/3x+5” in perpendicular lines slope1times slope 2 creates a negative (-1) example(-3/1)(1/3)=-1 so slope 1 multiplied by slope 2 is the opposite inverse which creates a negative 1
