Answer:
D. -17/2
Step-by-step explanation:
1/2 - 4 (1/2 + 1)^2
First we evaluate what is inside the parentheses
1/2 - 4 (3/2) ^2
Now we square what is inside the parentheses
1/2 - 4(9/4)
Now multiply
1/2 -9
Get a common denominator 9 = 9 *2/2 = 18/2
1/2 - 18/2
-17/2
The required probability is:
(51.25 - 45)/(55 - 45)=0.625
Answer:
x = 3/2, x = 1
Step-by-step explanation:
$43.25 - $7.00 = $36.25
$36.25 divided by $1.25 = 29.
