Answer:
The Arithmetic progression formed will be: 7, 12, 17, 22...
a = 7, d = 5
The nth term or an = a + (n-1)d
= 7 + (n-1)5
= 7 + 5n - 5
= 5n + 2
The answer is A. 5n + 2
Hope this helps!
Answer:
a) 21
b) 21
Step-by-step explanation:
Given 10 scores: 19, 15, 34, 29, 13, 35, 10, 19, 14, 22
a) Mean
= (sum of scores) / number of scores
= (19+15+ 34+ 29+ 13+ 35+ 10+ 19+ 14+ 22) / 10
= 210 / 10
= 21
b) one more score of 21 is added
hence
number of scores = 10 + 1 = 11
sum of scores = 210 + 21 = 231
Mean = (sum of scores) / number of scores
= 231 / 11
= 21
Answer:
Hey there,
Let the angle ABC = x
Let the angle CBE = y
Let the angle EBD = z
We want to find x.
So, we are given the following:
x+y+z=85
z=21
And y=z
therefore, both y and z must equal 21.
21+21=42
85-42=43.
Answer:
so the equation would be 4x (because he buys 4 books) + 0y (because he didn't buy any CDs) = 32 (or it could be $32). The slope would be 4.
