Answer:
-90
Step-by-step explanation:
M (Mean) = 20,500;
SD (Standard Deviation) = 55
1 ) 20,555 = 20,500 + 55 = M + 1 SD
Answer: 50% + 34.1% = 84.1%
2 ) 20.610 = 20,000 + 110 = M + 2 SD
Answer: 10% - ( 50% + 34.1% + 13.6% ) = 100% - 97.7% = 2.3%
3 ) 20,445 = 20,500 - 55 = M - 1 SD
Answer: 50% - 34.1% = 15.9%
Answer:
The nth term of the given sequence tₙ = 3 n - 7
Step-by-step explanation:
Given sequence - 4 , -1 , 2 , 5, 8 , .....
First term a = -4
The difference of two terms of a given sequence
d = -1 - (-4) = -1 +4 = 3
d = 2 - (-1) = 2 +1 = 3
d = 5 -2 = 3
d = 8 - 5 =3
The difference of two terms of a given sequence is equal
∴ The given sequence is in Arithmetic progression(AP)
The nth term of given sequence


<u><em>Final answer:</em></u>-
The nth term of the given sequence tₙ = 3 n - 7
6 marbles per person.
If we count the number of marbles in total, we get 24: 5+9+4+6= 24
Now that we know the Total # of marbles, we need to know how many people we need to distribute marbles to. We count Brian, Sarah, Jimi, and Juan and get 4 people in total.
To find how many marbles each person needs to receive, we then need to do 24 divided by 4.
When we do this, we get 6 marbles per person.
