Answer:
Step-by-step explanation:
r is the common ratio.
Third term minus first term is 48.
a₃ - a₁ = 48
a₃ = a₁r²
a₁r² - a₁ = 48
a₁(r²-1) = 48
r²-1 = 48/a₁
Fourth term minus second term is 144.
a₄ - a₂ = 144
a₂ = a₁r
a₄ = a₁r³
a₁r³ - a₁r = 144
a₁r(r²-1) = 144
r²-1 = 144/(a₁r)
48/a₁ = 144/(a₁r)
r = 3
:::::
r²-1 = 48/a₁
a₁ = 6
:::::
a₆ = a₁r⁵ = 1458
5 and 1 you multiple 5*1 to get 5 and add 5+1 to get 6
Looks like the graph is decreasing to me
Answer:
Option B
Step-by-step explanation:
Given:
total No. of students liking peas= 78
total no. of male students= 100
total number of students= 200
no. of male students liking peas= 42
Now we need to find are liking peas and being male independent or dependent events
P(likes peas)= 78/00
=0.39
=39%
P(likes peas/male) = 42/100
= 42%
as the two probabilities are not equal the two events are dependent.
Hence option B is correct: Dependent;
since these probabilities are not equal, the events are dependent!
