Find a6 of the geometric sequence: a1=4 and a3=36

1 answer:

8 0

Geometric sequence

an=a1(r)^(n-1)
so

given
a1=4
and a3=36

36=a3=4(r)^(3-1)
36=4(r)^2
9=r^2
3=r

an=4(3)^(n-1)
a6 is
a6=4(3)^(6-1)
a6=4(3)^5
a6=4(243)
a6=972

a6=972

Hello your question is incomplete attached below is the complete question

answer : There is not convincing statistical evidence to suggest that the proportion of customers who order dessert at each restaurant is not the same based on family classification. ( E )

Step-by-step explanation:

To arrive at this conclusion we will determine the Null and alternate hypothesis

H0 : Number that orders dessert is same based on family classification given

Ha : Number that orders dessert is not the same based on family classification given

from the question the p-value of Chi-square test is 0.092 > 0.05 hence we will fail to reject the null hypothesis. therefore we can conclude that
