Answer:
2.15%
Step-by-step explanation:
If you were to get the z-score for both 500 and 550 and then get the probability of both those z-scores. After getting the probability you would subtract both probability and get your answer.
Z-score:
550-400/2=3
500-400/2=2
Probability:
3 (from the Z-table) is .9987
2 (from the Z-table) is .9772
.9987-.9772= .0215
.0215 as a percentage is 2.15%
The answer would be A. If 4x + 6 is the number of boats made in 1 day, then multiplying that by 12 would give us the number of boats made in 12 days so the equation would look like this:
12(4x + 6)
Answer:
x=-1
Step-by-step explanation:
-3+75x<-75+3x
75x-3<-75+3x
75x-3<3x-7575x−3<3x−75
75x-3-3x<-75
72x-3<-75
72x<-75+3
72x<-72
x=-1
