Answer:
-48n-16
Step-by-step explanation:
-8 -8(6n +1)
= -8 + -48n + -8
= (-48n) + (-8 + -8)
= -48n + -16
Step-by-step explanation:
let f(x) be y
∴ y = 10x/9 +11
(y - 11 )× 9/ 10 = x
Interchange x->y and y->x
(x - 11)×9/10 = y
here y is your f⁻¹(x)
∴ f⁻¹(x) = (x - 11 )× 9/10
or, f⁻¹(x) = 9x/10 - 99/10
Option (D) is correct
Answer: unit rate = 1 / 5 = 0.2 inches per day
Step-by-step explanation:
The unit rate is the ratio that describes how one quantity changes as the other changes.You can find a unit rate from a graph the same way you find the slope.
1. Choose two points on the graph to find the slope
- (0,0) and (5,1)
x₁ y₁ x₂ y₂
2. Slope = y₂ - y₁ / x₂ - x₁ (This is essentially the change in y-coordinates divided by the change in x-coordinates.
unit rate = y₂ - y₁ / x₂ - x₁
unit rate = 1 - 0 / 5 - 0
unit rate = 1 / 5 = 0.2 inches per day
The standard deviation of a particular sample is equal to the standard deviation divided by the square root of the sample size. That is,
The mean of a particular sample is equal to the mean of the set the sample was taken from. That is,
