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%
Find the S.A of all the cubes and then add them together.
S.A = 6a²
a is the side length
S.A = 6(3)² = 54
S.A = 6(2)² = 24
S.A = 6(1)² = 6
Now add them all together.
54 + 24 + 6 = 84
So the total surface area is 84
Hope this helps :)
Answer:
The gambler's expected value if he makes the bet is $45.
Step-by-step explanation:
Expected value:
15% probability of a profit of $2000.
100 - 15 = 85% probability of having to pay $300, that is, a loss of $300.
The expected value is each outcome multiplied by it's probability, so:
The gambler's expected value if he makes the bet is $45.
Step-by-step explanation:
(7n − 5) / (2n + 5) approaches 7/2 as n approaches infinity. However, this is an alternating series. So the function is fluctuating between -7/2 and +7/2. So the limit does not exist.
