Answer:
64%
Step-by-step explanation:
The percentage of variation in the dependent variable explained by the estimated regression is calculated with the coefficient of correlation as follows:
First, square the coefficient of correlation: 0.8^2 = 0.64
And then, multiply this result by 100, so that, it is expressed as a percentage: 0.64*100 = 64%
First let's make both the miles and the hours ran improper fractions:
So, to find our miles per hour, we have to divide the miles by the hours to get: 
Answer:
C. 1/6
Step-by-step explanation:
The experimental probability is the probability that is obtained by dividing the number of times the required outcome has occurred by the total number of trials.
In the experiment given the color red is one of the six possible outcomes and the next time the experiment is performed the number of trials would be 1
so the experimental probability would be 1/6
If the previous number of trials were given then the probability would have been different.
Let's solve your equation step by step
(3^2)(x)-5=81
step 1:simplify both sides of the equation
(3^2)(x)-5=81
simplify.
9x-5=81
step 2:Add 5 to both sides.
9x-5+5=81+5
9x=86
divide both sides by 9.
9x/9=86/9
x=86/9
Answer:86/9
Hope this helps!
