Answer:
16%
Step-by-step explanation:
We solve using z score formula
= z = (x-μ)/σ, where
x is the raw score = 12.5 minutes
μ is the population mean = 17 minutes
σ is the population standard deviation = 4.5 minutes
z = 12.5 - 17/4.5
z = -1
Probability value from Z-Table:
P(x<12.5) = 0.15866
Converting to percentage
= 0.15866 × 100
= 15.866%
Approximately , the percentage of people living in Flint have a travel time to work that is less than 12.5 minutes is 16%

Answer:
Step-by-step explanation:
Area for triangle is equal to half base time perpendicular height.
note that it's 10cm X 12 cm that's how you get cm²
4(1-3n)-14>4(2n+3)-9n
4-12n-14>8n+12-9n
-12n-10>-n+12
-22>11n
-2>n
n<-2
