The R2 (R-square) of a multiple regression of y on x1 and x2 measures the . A) percentage of the variation in y that is explained by the variability of x1 B) percentage of the variation in y that is explained by the variability of x2 C) statistical significance of the coefficients in the sample regression equation D) percentage of the variation in y that is explained by the sample regression equation

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours
