Answer:
Step-by-step explanation:
|x+3|+7>8
|x+3|>8-7
|x+3|>1
either x+3>1
x>2
or x+3<-1
x<-4
Y = 125 when x is 24. Hope it helps
Answer:
Decrease the sample size.
Step-by-step explanation:
Margin of error is:
ME = CV × √(σ / n)
where σ is the population standard deviation, or:
ME = CV × √(p (1 − p) / n)
where p is the proportion.
In each case, the margin of error is directly proportional to the critical value, and inversely proportional to √n.
Lowering the confidence level will lower the critical value, which will decrease the margin of error. Decreasing the sample size will increase the margin of error.
So first we have to subtract 3y from 21 cause the oppisit of addition which is subtraction so you get 18y when we divide that with -8y and get y=2.25y
