Yes because when your multiply every thing together you’ll have 9/15 miles
Answer:
7.5 hours
Step-by-step explanation:
Constance's car has a 12-gallon gas tank.
She can travel 25 miles on one gallon of gas, so she can travel
miles using all gas from the tank.
Constance begins with a full tank of gas and drives at a constant rate of 40 miles per hour.
So, Constance can drive for
hours.
Parallel means that the two equations have the same slope,
so we have y = 8x + b so far.
Then we can just apply the slope to the given point by taking the y value and decreasing it by 40, due to the x value being 5
So in short, the equation that runs parallel to y = 8x-8 and intersect the point (5,2) is y = 8x -38
Answer:

So then the best answer for this case would be:
C. 2.78
Step-by-step explanation:
For this case we have the following probabability distribution function given:
Score P(X)
A= 4.0 0.2
B= 3.0 0.5
C= 2.0 0.2
D= 1.0 0.08
F= 0.0 0.02
______________
Total 1.00
The expected value of a random variable X is the n-th moment about zero of a probability density function f(x) if X is continuous, or the weighted average for a discrete probability distribution, if X is discrete.
If we use the definition of expected value given by:

And if we replace the values that we have we got:

So then the best answer for this case would be:
C. 2.78
