Answer:
Driver 1 score: 9
Driver 2 score: 3
Step-by-step explanation:
We are given the following in the question:
The number of marks scored on a driving test are y(x) is a dependent variable and the number of drinks taken by the driver is the independent variable(x).
Slope, m = -3
y-intercept,c = 18
Then, we can write the regression equation as:
Driver 1 consumed 3 drinks.
We put x = 3 in the regression equation.
Thus, the predicted driving 1 score for driver 1 is
Driver 1 predicted score is 9.
Driver 2 consumed 5 drinks.
We put x = 5 in the regression equation.
Thus, the predicted driving 2 score for driver 2 is
Driver 2 predicted score is 3.
Answer:
144 in^2
Step-by-step explanation:
There are four triangular sides to this square pyramid. According to the area-of-a-triangle formula, A = (1/2)(b)(h), which here is A = (1/2)(8 in)(5 in) = 20 in^2.
Thus, the total lateral (side) area is 4(20 in^2) = 80 in^2.
The area of the bottom is (8 in)^2, or 64 in^2.
Thus, the total surface area is 80 in^2 + 64 in^2, or 144 in^2.
Answer:
50%
Step-by-step explanation:
half of the numbers on dice are even
We know, Circumference = <span>π * Diameter
So, c = </span><span>π * 8
c = 8</span><span>π
In short, Your Answer would be Option C
