Answer:
Step-by-step explanation:
15 minutes = 1/4 hour
Therefore:
75 * 4 = the number of people riding in one hour
Thus:
the # of people riding in 1 hour * 4 = the # of people riding in 4 hours
1,500 people
300 people per hour is the rate

Hi everyone! I have a question!
Find the area of the shaded regions. Give your answer as a completely simplified exact value in terms of pi (no approximations.) THANKS!!!!!!
Answer:
7π
Step-by-step explanation:
SO first find the area of the whole circle
which has a radius of 3
a=πr^2
So 3^2=9
9π
Now the two circles which are the same in area due to having the same radius
so if you plug in the 1 for radius the answer would just be π or 1π
now multiply that by 2 becuase there are 2 identical circles
π*2=2π
Now subtract
9π-2π=7π
Answer:
Step-by-step explanation:
area of unshaded circle:
A=π*r^2=π*1=π
we have 2 circles so the area of both circles are 2π
area of the large circle is A(l)=Π*3^2=Π*9=9Π
area of the shaded region: A(s)=9Π-2Π=7Π

Step-by-step explanation:
Jim is a 60-year-old Anglo male in reasonably good health. He wants to take out a $50,000 term (that is, straight death benefit) life insurance policy until he is 65. The policy will expire on his 65th birthday. The probability of death in a given year is provided by the Vital Statistics Section of the Statistical Abstract of the United States (116th Edition).
x = age 60 61 62 63 64
P(death at this age) 0.01030 0.01357 0.01609 0.01981 0.02362
Jim is applying to Big Rock Insurance Company for his term insurance policy.
(a) What is the probability that Jim will die in his 60th year? (Round your answer to five decimal places.)
Using this probability and the $50,000 death benefit, what is the expected cost to Big Rock Insurance?
$
(b) Repeat part (a) for years 61, 62, 63, and 64.
Year Expected Cost
61 $
62 $
63 $
64 $
What would be the total expected cost to Big Rock Insurance over the years 60 through 64?
$
(c) If Big Rock Insurance wants to make a profit of $700 above the expected total cost paid out for Jim's death, how much should it charge for the policy?
$
(d) If Big Rock Insurance Company charges $5000 for the policy, how much profit does the company expect to make?
$
The probabilities are solved and:
a) The expected cost at the age 60 is $ 515.
b)
Year Expected Cost
61 $678.50
62 $804.50
63 $990.50
64 $1181
c) The policy should be priced at $4869.50.
d) The company expects to make a profit of $830.50.
Given data:
(a)
The probability that Jim will die in his 60th year is given as 0.01030.
The expected cost to Big Rock Insurance can be calculated by multiplying the probability of death at age 60 by the death benefit of $50,000:
Expected Cost at age 60 = (0.01030) * ($50,000)
Expected Cost at age 60 = $515
(b)
Expected Cost at age 61 = (0.01357) * ($50,000) = $678.50
Expected Cost at age 62 = (0.01609) * ($50,000) = $804.50
Expected Cost at age 63 = (0.01981) * ($50,000) = $990.50
Expected Cost at age 64 = (0.02362) * ($50,000) = $1181
Year Expected Cost
61 $678.50
62 $804.50
63 $990.50
64 $1181
(c)
The total expected cost to Big Rock Insurance over the years 60 through 64 can be obtained by summing up the individual expected costs:
Total Expected Cost = $515 + $678.50 + $804.50 + $990.50 + $1181 = $4169.50
To make a profit of $700 above the expected total cost, Big Rock Insurance should charge:
Policy Price = Total Expected Cost + Profit
= $4169.50 + $700
= $4869.50
Therefore, the policy should be priced at $4869.50.
(d)
If Big Rock Insurance charges $5000 for the policy, the expected profit can be calculated as:
Expected Profit = Policy Price - Total Expected Cost
= $5000 - $4169.50
= $830.50
Hence, the company expects to make a profit of $830.50.

How to compute the probability, expected cost, policy price and expected profit.(a) The probability that Jim will die in his 60th year is given as 0.01030.
The expected cost to Big Rock Insurance can be calculated by multiplying the probability of death at age 60 by the death benefit of $50,000 -
Expected Cost at age 60 = (0.01030) * ($50,000)
= $515
(b)
Expected Cost at age 61 = (0.01357) * ($50,000) = $678.50
Expected Cost at age 62 = (0.01609) * ($50,000) = $804.50
Expected Cost at age 63 = (0.01981) * ($50,000) = $990.50
Expected Cost at age 64 = (0.02362) * ($50,000) = $1181
Thus,
Year/Age Expected Cost
61 $678.50
62 $804.50
63 $990.50
64 $1181
(c)
The total expected cost to Big Rock Insurance over the years 60 through 64 can be obtained by summing up the individual expected costs:
Total Expected Cost = $515 + $678.50 + $804.50 + $990.50 + $1181
= $4169.50
To make a profit of $700 above the expected total cost, Big Rock Insurance should charge -
Policy Price = Total Expected Cost + Profit
= $4169.50 + $700
= $4869.50
Thus it is correct to state that the policy should be priced at $4869.50.
(d) If Big Rock Insurance charges $5000 for the policy, the expected profit can be calculated as:
Expected Profit = Policy Price - Total Expected Cost
= $5000 - $4169.50
= $830.50
Hence, the company expects to make a profit of $830.50.

5
-
8
full.
What is the total volume of the glass?
Step-by-step explanation:
x=volume of the glass
(1/3)x+63=(5/8)x
63=(5/8)x-(1/3)x
63=(15/24)x-(8/24)x
63=(7/24)x
multiply both sides by 24/7
(24/7)(63)=(24/7)(7/24)x
216=x
216 cm3 is the volume (answer)
1/3 of 216 is 72
72+63=135
135/216=0.625=5/8

Max delivers 8,520 pieces of mail in one year. If he delivers the same number of pieces of mail each month, about how many pieces of mail does he deliver in 2 months? Solve the problem and explain the steps you took to solve.
Answer:
Because there are 12 months in a year the ratio of the number of pieces of mail Max delivers in 12 months can be written as: 852012 or 7101 (720 pieces of mail per month).
Answer:
He would deliver 1420 mails in 2 month's
Step-by-step explanation:
First, I divided 8,520 by 12 because 12 month's in one 1 year
Then, I get 710, that is the amount he delivers each month
Lastly, I multiply 710 by 2 because that is the amount for 2 month's and it equals 1,420 so, the answer is 1,420 :)

15y + (x + 9y) = ? someone halp
Answer:
x = -24ySimplifying
15y + (x + 9y) = 0
Remove parenthesis around (x + 9y)
15y + x + 9y = 0
Reorder the terms:
x + 15y + 9y = 0
Combine like terms: 15y + 9y = 24y
x + 24y = 0
Solving
x + 24y = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-24y' to each side of the equation.
x + 24y + -24y = 0 + -24y
Combine like terms: 24y + -24y = 0
x + 0 = 0 + -24y
x = 0 + -24y
Remove the zero:
x = -24y

x = -24y

In ΔFGH, f = 83 inches, g = 11 inches and ∠H=60°. Find the length of h, to the nearest inch.
Answer: 78
Step-by-step explanation:
The length of h to the nearest inch is 78 inches.
What is Law of Cosines?Law of cosines of triangle states that for three length of sides of the triangle, a, b and c opposite to the angles A, B and C respectively can be related as,
a² = b² + c² - 2bc cos(A)
Given that, In ΔFGH,
f = 83 inches, g = 11 inches and ∠H = 60°.
Using the law of cosines,
h² = f² + g² - 2fg cos(H)
Substituting,
h² = 83² + 11² - (2 × 83 × 11) cos (60°)
= 7010 - (1826 × 1/2)
= 7010 - 913
= 6097
h = √6097 = 78.083 inches ≈ 78 inches
Hence the length of h is 78 inches.
