4*(2x+1)=(2x+1)+(2x+1)+(2x+1)+(2x+1)=
2x+2x+2x+2x+1+1+1+1=
=8x+4
I hope this is ok !
Answer:
2
Step-by-step explanation:
Answer:
Hi there!
The answer to this question would be:
Step-by-step explanation:
the general equation would be: y= -1/2x + 17/2
first you want to solve for the slope (m): you wanna do delta y (change of y ) over delta x (change of x)
so it goes like (11-9)/(-5-(-1)) and you get -1/2
then you want to solve for the y intercept (b)
so you plug in one of the point that you were given, in this case I am using (-1,9)
so now the equation looks like 9 = 1/2 +b then solve for b and you get b=17/2
Answer:
I believe the answer is D; 5/20+(-12/20).
Step-by-step explanation:
1/4-3/5
5/20-12/20
-7/20
5/20+(-12/20)
5/20-12/20
-7/20
Hope this helps! :D
Answer: Stratified random sampling
Step-by-step explanation:
- A sampling technique that involves the split of a population into smaller groups known as strata on the basis of some categories and then selecting individuals from each strata is known as Stratified random sampling.
Here, group of mean and women are two strata, and selecting individuals from each of them .
That means, this sampling method is "Stratified random sampling".
