Answer:

parallel=-2, perpendicular=1/2

Step-by-step explanation:

Parallel slopes mean the slopes are the same, and perpendicular slopes are the reciprocals of each other.

Answer:

Step-by-step explanation:

A line in a graph parallel/collinear to another line has same slope.

A line perpendicular to the another line has negative and reciprocal slope of the given line.

Answer:

(-5,1)

Step-by-step explanation:

Because the red line (graphical representation of one equation) and the blue line (graphical representation of the other equation) intersect at (-5,1), the solution to the systems of equations is (-5,1).

Answer: 600 canned foods was the total.

Step-by-step explanation: We need to find out what‘s 100% of 480. Since 480 canned foods is 80%, we can divide 480 by 8 which gives us 60. Aka 60 canned foods = 10%. Now, we multiply 60 by 10 which gives us 600. Hope this helps!

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

Let x = 8.132132132... .

Then 1000x = 8132.132132132... .

Subtracting x from 1000x eliminates the fractional part, leaving you

999x = 8132 - 8 = 8124

Then

x = 8124/999 = 2708/333

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.

(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 64 = (0.02362) * ($50,000) = $1181

Thus,

Year/Age      Expected Cost

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

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

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

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 :)
