B. 7
49 divided by 7 is 7.
To find the probability of the statistic class that it could be done at the period at 50.5 and 51.25 minutes and not their usual duration of 49 and 49 minutes so to get the probability you must subtract the time and would come up with 0.75 minutes and then divide it by 10 so the probability is 0.075
Answer:
b = 10
Step-by-step explanation:
The area (A) of a triangle is calculated as
A =
bh ( b is the base and h the height )
Here h = 3x + 15 and A = 15x + 75, thus
× b × (3x + 15) = 15x + 75
Multiply both sides by 2 to clear the fraction
b(3x + 15) = 30x + 150
Divide both sides by (3x + 15)
b =
← factor numerator and denominator
=
← cancel the factor (x + 5) on numerator/denominator
= 
= 10
