Answer:
(m−5)(2m−2)
=(m+−5)(2m+−2)
=(m)(2m)+(m)(−2)+(−5)(2m)+(−5)(−2)
=2m2−2m−10m+10
=2m2−12m+10
Answer:

Step-by-step explanation:
1. Make it so 1/4 is an eighth so you can subtract it from 5/8.
1/4 x 2 = 2/8
2. Subtract 2/8 from 5/8.
5/8 - 2/8 = 3/8
Daniel ate 2/8s of the left over pie, and there is 3/8s remaining.
Z-score for 30 = (30 - 25) / 5.8 = 0.8621
z-score for 20 = (20 - 25) / 5.8 = -0.8621
:
Note find probabilities from z-tables
:
Probability ( 20 < X < 30 ) = 0.8051 - 0.1949 = 0.6102
