Dacosta's math quiz scores are 70, 72, 99, 72, and 69. find the mean and median. which is a better description of dacosta's typical math quiz score?

mean = 76.4

median = 72

Step-by-step explanation:

to find the mean (the average)  you add all the numbers given together then divide by how many numbers were there

70+72+99+72+69=382

382/5=76.4

to find the median you go from smallest to largest trying to find the middle

69,70,72,72,99

70,72,72

72

i believe that the 72 reflects better on the grades he gets because there is only one grade over a 76 and most of his grades are closer to the 72

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680

c. (3,2,6) is the answer.
