The given regression shows the relationship between the numbers of car washed(x) and the amount earned for charity(y).
y = 10x + 20
We are to calculate the amount of charity if 50 cars are washed. Number of cars are represented by x, so by substituting x = 50 in above equation we can find the amount of charity that is earned by washing 50 cars.
y = 10(50) + 20 = $ 520
Thus, the charity can earn $520 if 50 cars come in for a wash.
2 1/2 for $6.25 is the answer
Hi again! so vertical angles are angles that are across from eachother, so it would be 5 and 7 and 6 and 8
2L = 2000mL
2000mL / 400mL = 5
therefore, each cup is filled exactly half way
There is 200mL in each of the 10 cups.
The interest would be $14.17 so the total in the account is $329.17.
you find this by using the formula:
I = P*R*T
I =300*.015*3
I = 14.17
