Answer:
x = -5
Explanation:
4(2x + 10) = 0
[ Simplify both sides of the equation ]
4(2x + 10) = 0
(4)(2x) + (4)(10) = 0 [Distribute]
8x + 40 = 0
[ Subtract 40 from both sides ]
8x + 40 − 40 = 0 − 40
8x = −40
[ Divide both sides by 8 ]
8x / 8 = −40 / 8
x = -5
45 is if you x it so it’s 45
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".
Answer:
a) It is a line where for every one block right, you go four blocks up. (0, -1) is on the line, because that is the y intercept.
b) 1=4x-1
2=4x
x=1/2
