The regression equation y = 1.3x + 6.8 approximates the number of minutes it takes an employee to drive to work, y, given the number of miles the employee has to drive, x.

which statement is true?
question 7 options:

for every extra mile an employee drives, the driving time increases by 6.8 minutes.

for every extra mile an employee drives, the driving time increases by 1.3 minutes.

for every extra minute an employee drives, the distance increases by 6.8 miles.

for every extra minute an employee drives, the distance increases by 1.3 miles.

For every extra mile an employee drives, the driving time increases by 1.3 minutes.

Step-by-step explanation:

y = 1.3x + 6.8

x is the number of miles, y is the time taken

each extra mile, the time increases by 1.3  and the constant is 6.8

say that x = 3, the time taken y = 1.3(3) + 6.8

= 3.9 + 6.8

y =10.7

the difference is 1.3.

for each extra mile, the time is increases by 1.3 minutes.

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
