Bob nale is the owner of nale’s quick fill. bob would like to estimate the mean number of gallons of gasoline sold to his customers. assume the number of gallons sold follows the normal distribution with a population standard deviation of 2.30 gallons. from his records, he selects a random sample of 60 sales and finds the mean number of gallons sold is 8.60.

where does the z at is it on the x axes or on the y axes any way if it is on the y axes put it horizontally and if it is on the x axes put it vertically

slope =   (y2 -y1) ÷ (x2 -x1)

slope = (0 -0) / (-5, -7)

slope = 0 / -12 = 0

the slope of the line is zero.   it is perfectly horizontal.

step-by-step explanation:

d is ur answer hopes this i dont really know how to explain it to u.
