Step-by-step explanation:
Answer:
slope:2
Step-by-step explanation:
Slope is rise/run, or change in y/change in x.
With that being said, we only need two points to solve this.
Let's take the points (0,7) and (1,9)
The formula for finding the slope from two points is m=(y2-y1)/(x2-x1).
M is the slope.
y2 would be the y-value of the second point,9. y1 would be the y-value of the first point, 7.
x2 would be the x-value of the second point, 1. x1 would be the x-value of the first point, 0.
Plugging those values in to the formula, we get m=(9-7)/(1-0)
Simplifying, we get m=2/1, which is m=2.

Answer:
On average, the project takes 4 weeks to complete.
Step-by-step explanation:
We have these following probabilities:
25% probability that the activity takes 2 weeks.
50% probability that the activity takes 4 weeks.
25% probability that the activity takes 6 weeks.
How long does the project now take to complete (on average)
We multiply each duration by it's probability.
0.25*2 + 0.5*4 + 0.25*6 = 4
On average, the project takes 4 weeks to complete.
y = (9x) ^ (1/3)
exchange x and y then solve for y
x = (9y) ^ (1/3)
cube each side
x^3 = 9y
divide each side by 9
1/9 x^3 = y
the inverse function is 1/9 x^3
