Answer:
Point estimate is 16 and Margin of error is 9
Step-by-step explanation:
The point estimate is given by the following formula:
Point estimate = (Lower Bound + Upper Bound) / 2
Replacing we have:
Point estimate = (7 + 25) / 2 = 32/2
Point estimate = 16
Now, the margin of error is given by the following equation:
Margin of error = (Upper Bound - Lower Bound) / 2
Margin of error = (25 -7) / 2 = 18/2
Margin of error = 9

Answer:
<h2>x=11/2</h2>
Step-by-step explanation:
solution
We going to do this process in a stepwise manner
given the expression
18=6(2x – 8)
1. open bracket on the left-hand side (distributive property)
18=12x-48
2. collect like terms
18+48=12x
66=12x
3. divide both sides by 12 we have
x= 66/12
x= 33/6
x=11/2
Answer:
(x+2) (x+1)
