Answer:
7oz of water
Step-by-step explanation:
6(1/2)= 3; 6(2/3)= 4; 3+4=7
-160
Since -(20x8) the answer would be -160
The answer should be (3b + 2)(3b - 2) since if you multiply those two, you will get back to original equation.
Hope this helps!
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
