Answer:
1) 128
2) 32
Step-by-step explanation:
1) 8C1×4C1×4C1 = 128
2) 5C1 + 5C2 + 5C3 + 5C4 + 5C5
= 32
So far your getting all of them right. But, maybe next time upload a better picture because it’s hard to see what you wrote.
Answer:
the regression line
Step-by-step explanation:
Answer:
f^-1(x) = 9(x+2)
Step-by-step explanation:
To find the inverse function, exchange x and y and then solve for y
y = 1/9 x -2
Exchange x and y
x = 1/9 y-2
Solve for y
Add 2 to each side
x+2 = 1/9 y-2+2
x+2 = 1/9y
Multiply each side by 9
9(x+2) = 9*1/9y
9(x+2) = y
The inverse function
f^-1(x) = 9(x+2)
