TRUE I REALLY HOPE THIS HELPS YOU OUT
Step-by-step explanation:
Answer: 
, where n is a natural number.
Step-by-step explanation:
A series can be represented in a summation or sigma notation.
Greek capital letter, ∑ (sigma), is used to represent the sum.
For example: 
, where n is a natural number.
The given series : 1,4,9,16 which can be written as 
.
So , we can write it as
, where n is a natural number.

Answer:
The events are not mutually exclusive because the P(A and B)=0.1 not 0
Step-by-step explanation:
Mutual exclusive events are those that can't happen at the same time.For example Tossing a coin, Head and Tail are mutually exclusive events because you can't get a Head and a tail at the same time.Another example is turning left and turning right are mutually exclusive because you can't do both at the same time.
If events are mutually exclusive, they can happen at the same time.
Mathematically,the probability of mutual exclusive events follows;
P(A and B)=0 ------------The probability of A and B together equals 0
P(A or B) = P(A)+P(B)-----The probability of A or B equals the probability of A plus the probability of B.
In this question you are given;
P(A)=0.3
P(B)=0.6
P(A or B) =P(A) + P(B)= 0.3+0.6 =0.9
0.9≠0.8 thus the events are not mutually exclusive.
Answer:
aₙ = 31n - 5
Step-by-step explanation:
The terms of your sequence are.
26, 57, 88, …
This is an arithmetic sequence, because there is a constant difference of 31 between consecutive terms.
The explicit formula for the nth term of an arithmetic sequence is
aₙ = a₁ + d(n - 1 )
a₁ is the first term, and d is the difference in value between consecutive terms. Thus,
aₙ = 26 + 31(n - 1) = 26 + 31n - 31
aₙ = 31n - 5
The explicit rule for the arithmetic sequence is aₙ = 31n - 5.
