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

What does (A) equal?
Answer:
a = -27
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define
-2/3a - 6 = 12
Step 2: Solve for a
Add 6 to both sides: -2/3a = 18Divide -2/3 on both sides: a = -27Answer: a = -27
Step-by-step explanation:
-2/3a - 6 = 12
ADD 6 TO BOTH SIDES
-2/3a = 18
MULTIPLY BY 3 TO BOTH SIDES
-2a = 54
now you want to get the a by itself so DIVIDE BY -2
so... a=-27
Ayden’s school took a field trip. A total of 32 vehicles were needed for the trip. Some students took the bus, and some students car-pooled. There were 27 people on each bus and 3 people in each car. 408 people altogether attended the trip. How many buses and cars were needed for the trip?
Step-by-step explanation:
Let x be the number of buses for the trip.
Then (32 - x) is the number of cars for the trip.
We have 27x + 3(32 - x) = 408.
=> 27x + 96 - 3x = 408
=> 24x = 312
=> x = 13
Hence there are 13 buses and (32 - 13) = 19 cars.

What is the missing number in the series?
1, 16, 81, __, 625, 1296
Answer:
256
Step-by-step explanation:
We are given the series
1, 16, 81, __, 625, 1296
The missing number in the sequence is the fourth term
From the above sequence, we know that
1, 4², 9² , __, 25² , 36²
Difference between first term = 4 - 1 = 3
9 - 4 = 5
x - 9 = 7
x = 9 + 7 = 16
Hence, the fourth term = 16²

fine the lower and upper quartiles and interquetile range.
5, 12, 17, 23, 28, 31, 37, 41, 42, 49, 54, 58, 65, 68, 73, 71.
Answer:
Lower Quartile = 25.5
Upper Quartile = 61.5
IQR = 36
Step-by-step explanation:
Given data is:
5, 12, 17, 23, 28, 31, 37, 41, 42, 49, 54, 58, 65, 68, 73, 71
The lower quartile is the first quartile and upper quartile is the third quartile.
A median divides the data set in two equal halves.
Lower quartile also known as first quartile is the middle value in the first half.
The first half is:
5, 12, 17, 23, 28, 31, 37, 41
As the number of values is even, the quartile will be the average of two middle values
[tex]Q_1 = \frac{23+28}{2} =\frac{51}{2}= 25.5[/tex]
Upper quartile is the average of middle two values in the second half when the number of values is even.
42, 49, 54, 58, 65, 68, 73, 71
[tex]Q_3 = \frac{58+65}{2} = \frac{123}{2} = 61.5[/tex]
Interquartile range is the difference of third quartile and first quartile
[tex]IQR = Q_3 - Q_1 = 61.5-25.5=36[/tex]
Hence,
Lower Quartile = 25.5
Upper Quartile = 61.5
IQR = 36

Answer:
B: (x + 1) = (y - 2)²
Step-by-step explanation:
0 = y² - x - 4y + 3
We want to find the equation of the parabola in vertex form.
The format for the vertex form is;
y = a(x - h) + k
Where (h, k) is the coordinate of the vertex.
Thus, let's transform 0 = y² - x - 4y + 3 into the vertex form
Let's rearrange to get;
x - 3 = y² - 4y
Let's use method of completing the square to get right hand side;
x - 3 = (y - 2)² - 4
Add 4 to both sides to get;
x - 3 + 4 = (y - 2)²
(x + 1) = (y - 2)²

Echelon form of augmented matrix [tex]\left[\begin{matrix} 2&3&-5&b_1\\0&\frac{47}{2} &\frac{101}{2} &b_2-\frac{17}{2}b_1 \\0&0&\frac{-10}{3} &b_3-2\frac{b_1}{6} \end{matrix}\right][/tex]

[tex]\displaystyle \sin A=\frac{1}{3}[/tex]
Step-by-step explanation:
Trigonometric Ratios
The ratios of the sides of a right triangle are called trigonometric ratios. The longest side of the triangle is called the hypotenuse and the other two sides are called the legs.
We are given a triangle with side lengths of 3, [tex]\sqrt{72}[/tex], and 9, where 9 is the hypotenuse. Before applying the trigonometric ratios, we must check if the triangle is right, and the Pythagora's theorem is satisfied:
[tex]9^2=3^2+(\sqrt{72})^2[/tex]
81=9+72=81
Now we're sure it's a right triangle, we apply the sine formula:
[tex]\displaystyle \sin A=\frac{\text{opposite leg}}{\text{hypotenuse}}[/tex]
The opposite leg to A is 3, and the hypotenuse is 9, then:
[tex]\displaystyle \sin A=\frac{3}{9}[/tex]
Simplifying:
[tex]\boxed{\displaystyle \sin A=\frac{1}{3}}[/tex]

b) { y = -x + 1
y = -2x - 2
Answer:
Solving the equations we get: x = -3, y = 4
The solution set is: (-3,4)
Step-by-step explanation:
We need to solve the system of equation and find value of x and y
The system of equation given is:
[tex]y = -x + 1\\y = -2x - 2[/tex]
Let:
[tex]y = -x + 1--eq(1)\\y = -2x - 2--eq(2)[/tex]
We would use substitution method.
Put value of y from eq(1) into eq(2) and find value of x
[tex]Eq(2)\;is:\\y=-2x-2\\Put\:y=-x+1\\-x+1=-2x-2\\-x+2x=-2-1\\x=-3[/tex]
So, we get x = -3
Now, for finding value of y, put value of x = -3 into equation 1
[tex]y=-x+1\\Put\:x=-3\\y=-(-3)+1\\y=3+1\\y=4[/tex]
So, we get y=4
Solving the equations we get: x = -3, y = 4
The solution set is: (-3,4)

You are choosing between two different cell phone plans. The first plan charges a rate of 23 cents per minute. The second plan charges a monthly fee of $49.95 plus 9 cents per minute. How many minutes would you have to use in a month in order for the second plan to be preferable?
Answer:
357 minutes
Step-by-step explanation:
I subtracted 9 cents/minute from the 23 cents/minute to get 14 cents to get the difference between the two per minute charges. I then divided the monthly cost of $49.95 by .14 to get 356.79... So if you used 357 minutes in a month, the second plan would be 3 cents cheaper at $82.08 (.09 x 357= 32.13 + 49.95), vs. the first plan costing $82.11 (.23 x 357). At 356 minutes the first plan would still be cheaper.
