A number - n
five times the number - 5n
nine more than five times the number - 5n+9
The answer is D.
The answer is (3x - 4) (x + 3)
1) Given binomials:
First binomial 7r - 5
Second binomial 5r + 8
2) To pass from 7r to 5r you have to subtract 2r, so the first term of the binomial to be subtracted is 2r
3) To pass form - 5 to + 8, you have fo subtract - 13
4) So the answer is 2r - 13, option b.
Answer:
2nt one
Step-by-step explanation:
The Standard Deviation is a measure of how spread out numbers are. Standard deviation can be calculated by the expression as follows:
s = √∑(x - x(mean))^2/n-1
x(mean) = 24
s = √∑(x - 24)^2 / 7-1
<span>s = 6.11
