If Sadie earns $11.25 per hour, her earnings will vary directly with the number of hours that she has worked per week.
If she made $146.25 in a work week, she worked 13 hours.
13 hours x 11.25 = 146.25
The events
are independent if and only if
. Under this condition, we have conditional probabilities
![P(A\mid B)=\dfrac{P(A\cap B)}{P(B)}=\dfrac{P(A)\cdot P(B)}{P(B)}=P(A)](https://tex.z-dn.net/?f=P%28A%5Cmid%20B%29%3D%5Cdfrac%7BP%28A%5Ccap%20B%29%7D%7BP%28B%29%7D%3D%5Cdfrac%7BP%28A%29%5Ccdot%20P%28B%29%7D%7BP%28B%29%7D%3DP%28A%29)
![P(B\mid A)=P(B)](https://tex.z-dn.net/?f=P%28B%5Cmid%20A%29%3DP%28B%29)
so the answer is D.
Answer:
(7,4)
Step-by-step explanation:
The midpoint formula is:
![M=(\frac{x_1+x_1}{2},\frac{y_1+y_2}{2})](https://tex.z-dn.net/?f=M%3D%28%5Cfrac%7Bx_1%2Bx_1%7D%7B2%7D%2C%5Cfrac%7By_1%2By_2%7D%7B2%7D%29)
Let (5,6) be x₁ and y₁ and let's let (9,2) be x₂ and y₂. Thus, the midpoint is:
![M=(\frac{5+9}{2},\frac{6+2}{2})](https://tex.z-dn.net/?f=M%3D%28%5Cfrac%7B5%2B9%7D%7B2%7D%2C%5Cfrac%7B6%2B2%7D%7B2%7D%29)
Add:
![M=(\frac{14}{2},\frac{8}{2})](https://tex.z-dn.net/?f=M%3D%28%5Cfrac%7B14%7D%7B2%7D%2C%5Cfrac%7B8%7D%7B2%7D%29)
Divide by 2:
![M=(7,4)](https://tex.z-dn.net/?f=M%3D%287%2C4%29)
So, our midpoint is (7,4).
And we're done!
