True [87]3 years ago
7 0

Answer:

Michelle must get an 80 on her next test to keep her average score.

Step-by-step explanation:

Since Michelle got an average score of 80 on two tests, to determine what score she must get on the third test so that her average score for the three tests is the same as the average score for the first two tests, the following calculation must be performed:

X / 2 = 80

X = 80 x 2

X = 160

X x 3 = 80 x 3

X x 3 = 240

X = 240/3

x = 80

So, Michelle must get an 80 on her next test to keep her average score.

What is the first term in a geometric sequence if the common ratio is −3 and the sum of the first six terms is 1,274?Hint: cap s
Ber [7]

Answer is   -7

=============================================

Work Shown:

s_n = a_1*(1-r^n)/(1-r)

s_6 = a_1*(1-r^6)/(1-r)

s_6 = x*(1-(-3)^6)/(1-(-3))

s_6 = x*(1-729)/(1+3)

s_6 = x*(-728)/4

s_6 = x*(-182)

s_6 = -182x

-182x = s_6

-182x = 1274

x = 1274/(-182)

x = -7 is the first term of the geometric sequence

------------

Extra info:

The first six terms of this geometric sequence is

-7, 21, -63, 189, -567, 1701

those six terms add to

-7+21+(-63)+189+(-567)+1701 = 1274

which verifies we have the right answer.
