Mike was in charge of collecting contributions for the food bank he received contrubutiins of $50,$80,$60,$50, and $90 find the mean and median of the contributions

Mean = 66, Median = 60

Step-by-step explanation:

Mike was in-charge of collecting contributions for the food bank.

He received contributions, data is given below.

$50, $80, $60, $50, and $90

To find the mean we add all the numbers and then divide it to the number of the values.

Mean =

          =

Mean = 66

To find the median first we arrange the values in lowest to greatest order.

50, 50, 60, 80, 90

Median is the middle number of the data set.

Therefore median would be $60

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
