15.89$ spent on Seven monster drinks hope it helped:)
We are given a line with the following data:
r-value = 0.657 (r)
standard deviation of x-coordinates = 2.445 (Sx)
standard deviation of y-coordinates = 9.902 (Sy)
We are asked to find the slope of the line up to 3 decimal places.
To find the slope of the line, based on the data that we have, we can use this formula:
slope, b = r * (Sy / Sx)
substitute the values to the formula:
b = 0.657 * ( 9.902 / 2.445 )
Solve for the b.
Therefore, the slope of the line is
b = 2.66078, round off to three decimal places:
b = 2.661 is the slope of the line.
Answer:
To find average speed, you divide total distance by total time.
The sale per linear feet is $16.75.
First, we need to find the total amount of sales, so we have to subtract the returns and discounts.
10342 - 217 - 599 = 9529
Now, divide this amount by the amount of linear feet.
9529 / 575 = 16.57
You could see the pattern
it cost 3.8 cent to print 1 dollar,
It cost 2 x 3.8 cents to print 2 dollar
it cost 3 x 3.8 cents to print 3 dollar
First equation
f(x) = 3.8 x
Same with second equation,
f(x) = 15x
for equation 3, it would be :
y = 1.50 x - 0.8x
Hope this helps
