Answer:

The answer is b.)  -5.2 degrees

Step-by-step explanation:

to find the mean of this problem you have to add all numbers and then divide it by how many numbers there is.

so you have to add  -42+ -17+14+-4+23 and that'll equal -26

so you take -26 and divide it by 5 because thats how many numbers their are to divide

-26 divided by 5 is (-5.2)

If a geometric sequence has a2 = 495 and a6 = 311, approximate the value of the common ratio ???? to four decimal
shtirl [24]

Answer:

r = 0.8903

Step-by-step explanation:

given,

a₂ = 495

a₆ = 311

geometric  sequence formula

                       a_n = ar^{n-1}

                       a_2 = ar^{2-1}

                       a_2 = ar...................(1)

                       a_6 = ar^{6-1}

                       a_6 = ar^5................(2)

dividing equation (2) by (1)

                     \dfrac{a_6}{a_2} = \dfrac{ar^5}{ar}

                     \dfrac{311}{495} = r^4

                     r^4 = 0.628

                     r = 0.8903

hence, the common ratio of the geometric sequence is r = 0.8903
