A four-day charity fundraiser received 53 donations on the first day, 49 donations on the second day, 43 donations on the third day, and 63 donations on the final day. What was the mean number of donations per day?

mean = 52

Step-by-step explanation:

Just add all four together and divide by 4. That's the mean.

Sum (49 + 43 + 53 + 63)/4 = 208

Mean = 208 /4 = 52

is only a line? i think so

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y

0       8

1       7.6

2       7.2
