The answer is 18.6, because when multiplying all the variables with the coefficients the equation is 1/2*6+15.6, 6 turns into 3 because it is halved and the rest of the equation stays the same so the new equation now is 3+15.6 and you simply add them and it is 18.6.
Answer: 85.06 feet/second

(1 mile =5280 feet.)
1 hour= 60 x 60 seconds = 3600 seconds.
Explanation:
To make it feet per second divide:
306240/3600
85.06
feet/second
7 hours because 1 load = 1 hour so 7 loads = 7 hours
Since the standard deviation is the square root of variance. The only times where the standard deviation is greater than the variance is when the variance is between the values 0 and 1 exclusively. For example, the square root of 0.25 is 0.5.
First distribute the negative through the parenthesis on the left and the 2 on the right.
-5 -15y +1 = 14y -32 - y
Combine like terms on the right and left
-4 -15y = 13y -32
Now move the variables to one side and the constants to the other.
Subtract 13y from both sides
-4 -28y = -32
Add 4 to both sides
-28y = -28
Divide both sides by -28
y = 1
