The test scores of five students for the first two tests of the semester are shown in the table below. Test Test Scores
1 77, 82, 69, 85, 93
2 75, 76, 71, 68, 72

a
MAD of Test 1 > MAD of Test 1
b
MAD of Test 1 = MAD of Test 2
c
MAD of Test 2 < MAD of Test 1

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
