a)
The cost per payment is 155.5.
b)
The value of 3 in the standard deviation principle is 1376.711.
We have,
a)
To calculate E(X^ 105), we first need to find the probability distribution of X after applying the deductible of 105.
Any loss below 105 will result in no payment, and any loss above or equal to 105 will result in payment equal to the loss minus the deductible.
Thus, the probability distribution of the payments.
Payment: 0 0 0 29 29 75 75 75 75 105 245 419 419
Probability: 0 0 0 1/12 1/12 1/6 1/6 1/6 1/6 1/12 1/12 1/12 1/12
Using this probability distribution, we can calculate E(X^ 105) as follows:
E(X^ 105) = 0^2 * 0 + 29^2 * (1/12 + 1/12 + 1/12 + 1/12) + 75^2 * (1/6 + 1/6 + 1/6 + 1/6) + 105^2 * (1/12) + 245^2 * (1/12) + 419^2 * (1/12)
= 34390.5833
The cost per payment ex(105) is simply the expected payment per policyholder, which can be calculated as follows:
ex(105) = 29 (1/3) + 75 * (2/3) + 105 * (1/6) + 245 * (1/6) + 419 * (1/6)
= 155.5
b)
The standard deviation principle states that the total cost of claims, including the deductible, should be equal to the product of the standard deviation and the value of the insurance against risk.
In this case, the insurance against risk is the maximum amount that the insurance company is willing to pay per policyholder, which is 105. Thus, we have:
105 + Bo = s(X) x VaR
where s(X) is the standard deviation of X and VaR is the value at risk, which is the amount that the company expects to pay out with a certain probability (usually 99% or 99.5%).
We can solve for Bo as follows:
Bo = s(X) * VaR - 105
Assuming a VaR of 99%, we need to find the 1% percentile of X, which is the value x such that P(X ≤ x) = 0.01.
From the empirical distribution, we can see that the 1% percentile is 94. Thus, we have:
VaR = 105 - 94 = 11
To calculate s(X), we first need to find the mean of X, which is:
mean(X) = (94 + 3104 + 2134 + 4*180 + 210 + 350 + 524)/13 = 224
Using the formula for the sample standard deviation, we get:
s(X) = √((1/12)((94-224)^2 + 3(104-224)^2 + 2*(134-224)^2 + 4*(180-224)^2 + (210-224)^2 + (350-224)^2 + (524-224)^2))
= 142.701
Now,
Bo = 142.701 x 11 - 105
= 1376.711
Thus,
The cost per payment is 155.5.
The value of 3 in the standard deviation principle is 1376.711.

Thee factory is able to provide 94.38 boxes per hour to the warehouse.
How to calculate the valueRate = (2000 - 1245) / 8 = 94.38 boxes per hour
Therefore, the factory is able to provide 94.38 boxes per hour to the warehouse.
Boxes added in 40 hours = rate * time = 94.38 * 40 = 3,775.2
Therefore, the inventory at the end of a 40-hour work week would be:
1245 + 3775.2 = 5020.2 boxes
rate = (50000 - 1245) / time
Simplifying this equation, we get:
time = (50000 - 1245) / rate = 511.64 hours (rounded to two decimal places).
Therefore, it will take approximately 511.64 hours to fill the warehouse to its 50,000 box capacity,

Based on the Normal model N( 100, 15) describing IQ scores, what percent of people's IQs would you expect to be a) over 80? b) under 90? c) between 112 and 132?
The percentage of people's IQ over 80 is 9.18%, the percentage of people's IQ under 90 is 25.14% and the percentage of people's IQ between 112 and 132 is 8.23%
Then,
a) Over 80:
The z-score for 80 is (80-100)/15 = -1.33
Using a standard normal distribution table , we can evaluate that the area under the normal curve to the right of -1.33 is approximately 0.9082.
Therefore, the percentage of people's IQs that will be over 80 is approximately
(1-0.9082) x 100%
= 9.18%.
b) Under 90:
The z-score for 90 is (90-100)/15 = -0.67
Using a standard normal distribution table, we can evaluate that the area under the normal curve to the left of -0.67 is approximately 0.2514.
Therefore, the percentage of people's IQs that will be under 90 is approximately
0.2514 x 100%
= 25.14%.
c) Between 112 and 132:
The z-score for 112 is (112-100)/15 = 0.8
The z-score for 132 is (132-100)/15 = 2.13
Using a standard normal distribution table, we can calculate that the area under the normal curve between these two z-scores is approximately 0.0823.
Therefore, the percentage of people's IQs that will be between 112 and 132 is approximately
0.0823 x 100%

A cubical container is 4/5 filled with water. It contains 2.7l of water. Find the base area of the container
Answer:
225 cm²
Step-by-step explanation:
The container has 2.7L of water in it but it is only 4/5 full
Therefore if the container were to be filled entirely with water it would contain
2.7 x 5/4 = 3.375 Liters
This, therefore is the volume of the container is 3.375 L
3.375 L = 3.375 x 1000 cm³
= 3, 375 cm³
The volume of a cube of side a is given by
V = a³
The base area of a cube of side a is given by
A = a²
We have calculated the volume of the cube as 3.375 cm³
Therefore each side of the cubical container
[tex]a = \sqrt[3]{3375} = 15[/tex] cm
The base area is
a² = 15²

e. P(-z0 ≤ z ≤ 0)= 0-2755 f. P(-2 < z < z)=0.9746 g. P(z >z0)=0.5 h. P (z ≤ zo)= 0.0043
The values of the standard normal random variable z, such that the probability of the following are satisfied: a. zo = -2.17; b. zo = 2.58; c. zo = 1.645; d. zo = 1.44.; e. zo = 0.37; f. zo = 1.96; g. zo = 0; h. zo = 0.
a. P(z ≤ zo) = 0.0151:
zo = -2.17.
b. P(-z0 ≤ z ≤ z0)=0.99
Since the standard normal distribution is symmetric, therefore, finding the z-score corresponding to probability: (1+0.99)/2 = 0.995.
zo = 2.58.
c. P(-zo ≤ z ≤ zo)=0.90:
Using the same reasoning as above, z-score for probability: (1+0.90)/2 = 0.95.
zo = 1.645.
d. P(-z0 ≤ z ≤ zo) = 0.8154:
probability of being outside and inside the range (-zo, zo) respectively:
P(z ≤ -zo) = P(z ≥ zo) = (1 - 0.8154)/2 = 0.0923
P(-zo ≤ z ≤ zo) = 1 - P(z ≤ -zo) - P(z ≥ zo) = 1 - 2(0.0923) = 0.8154
z-score for probability: (1+0.8154)/2 = 0.9077.
zo = 1.44.
e. P(-zo ≤ z ≤ 0) = 0.2755:

zo = 0.37.
f. P(-2 < z < zo) = 0.9746:
zo = 1.96.

Using the partial fractions technique, the function f(x) = 68x+168/ x^2+2x-24 can be written as a sum of partial fractions
We can express f(x) as a sum of partial fractions as: f(x) = (-10 / (x + 6)) + (78 / (x - 4))
To write the function f(x) = [tex](68x + 168) / (x^2 + 2x - 24)[/tex] as a sum of partial fractions, we first need to factor the denominator:
[tex]x^2 + 2x - 24 = (x + 6)(x - 4)[/tex]
So we can write:
f(x) = (68x + 168) / ((x + 6)(x - 4))
Now we can use the method of partial fractions to express f(x) as a sum of simpler fractions:
f(x) = A / (x + 6) + B / (x - 4)
where A and B are constants that we need to find. To do this, we can multiply both sides of the equation by the common denominator (x + 6)(x - 4):
(68x + 168) = A(x - 4) + B(x + 6)
Expanding and collecting like terms, we get:
68x + 168 = (A + B) x + (6B - 4A)
Since this equation holds for all values of x, we can equate the coefficients of x and the constant terms separately:
68 = A + B
168 = 6B - 4A
Solving these two equations simultaneously, we get:
A = -10
B = 78
Therefore, we can express f(x) as a sum of partial fractions as:
f(x) = (-10 / (x + 6)) + (78 / (x - 4))

The maximum profit occurs when 34 offices are painted per month, and the maximum profit is R13500.
Based on the given information, Brush Pro is an one-man paint business owned by Banele and their monthly profit, P, depends on the number of offices painted per month, x. The profit function is given as P(x) = -x + 27x^2 + 132x + 2970, where 0 < x < 34.
To find the maximum profit, we need to find the vertex of the parabolic function. The vertex is located at x = -b/2a, where a = 27, b = 132.
x = -132/(2*27) = -2.44
Since x must be between 0 and 34, the maximum profit will occur at x = 0 or x = 34. We need to evaluate P(0) and P(34) to determine which one is the maximum.
P(0) = -0 + 27(0)^2 + 132(0) + 2970 = 2970
P(34) = -34 + 27(34)^2 + 132(34) + 2970 = 13500

Karl has taken a three-year personal loan of $5000 at 7.25% per year, compounded monthly. The loan requires monthly payments. What is the total amount Karl will pay to the bank?
≈≈≈Answer:
Step-by-step explanation:
To calculate the total amount Karl will pay to the bank, we need to find the monthly payment and then multiply it by the total number of payments over three years.
First, we need to calculate the monthly interest rate. Since the loan is compounded monthly, we divide the annual interest rate by 12:
Monthly interest rate = 7.25% / 12 = 0.006041667
Next, we need to calculate the total number of payments Karl will make over the course of the loan. Since he will be making monthly payments for three years, there will be a total of:
Total number of payments = 3 years x 12 months/year = 36 payments
To calculate the monthly payment, we can use the formula for the present value of an annuity:
Monthly payment = P * (r / (1 - (1 + r)^(-n)))
where P is the principal amount (in this case, $5000), r is the monthly interest rate, and n is the total number of payments.
Plugging in the values, we get:
Monthly payment = [tex]5000 * \frac{0.006041667}{(1-(1+0.006041667^{-36} )} = $154.96[/tex]
Finally, we can calculate the total amount Karl will pay to the bank by multiplying the monthly payment by the total number of payments:
Total amount paid = Monthly payment x Total number of payments = $154.96 x 36 = $5,578.56
Therefore, the total amount Karl will pay to the bank is $5,578.56

The total cost of the policy can be calculated by multiplying the annual premium by the number of years in the policy term:
total cost of policy = annual premium * number of years in policy term
The number of months in a year is 12.
Bruce Lovegren purchased the policy on April 14, 1977, so the policy was in effect for 10 years and 8 months, or 128 months.
The annual premium as follows:
total cost of policy = $15,000
number of years in policy term = 10
annual premium = total cost of policy / number of years in policy term
annual premium = $15,000 / 10
annual premium = $1,500
monthly premium = annual premium / 12
monthly premium = $1,500 / 12
monthly premium = $125

recall the equation for a circle with center (h,k)and radius r. at what point in the first quadrant does the line with equation y
The equation for a circle with centre (h,k) and radius r is (x-h)^2 + (y-k)^2 = r^2. To find the point where the line with equation y = mx intersects the circle in the first quadrant, we can substitute y = mx into the equation for the circle.
(x-h)^2 + (mx-k)^2 = r^2
Expanding and simplifying:
x^2 - 2hx + h^2 + m^2x^2 - 2kmx + k^2 = r^2
Grouping the x terms:
(1 + m^2)x^2 - 2(h+km)x + h^2 + k^2 - r^2 = 0
This is a quadratic equation in x, which we can solve using the quadratic formula:
x = [2(h+km) ± sqrt(4(h+km)^2 - 4(1+m^2)(h^2+k^2-r^2))] / 2(1+m^2)
Simplifying:
x = (h+km) ± sqrt[(h+km)^2 - (h^2+k^2-r^2)m^2] / (1+m^2)
Since we're looking for a point in the first quadrant, we want the positive solution for x. Once we find x, we can plug it back into y = mx to get the y-coordinate of the point.
Note that there may be 0, 1, or 2 solutions depending on the specific values of h, k, r, and m. If there are 2 solutions, one will be in the first quadrant and the other in the fourth quadrant. If there is 1 solution, it will be on the border between the first and fourth quadrants. If there are 0 solutions, the line does not intersect the circle in the first quadrant.

The tables are completed as follows:
Table 1: f(x) = 30.Table 2: f(x) = 1.301.How to complete the table?For Table 1, we have an exponential function defined as follows:
f(x) = b^x.
We have that when x = 0.699, f(x) = 5, hence the base b is obtained as follows:
b^0.699 = 5
b = 5^(1/0.699)
b = 10.
Hence, when x = 1.477, the value of f(x) is given as follows:
f(x) = 10^1.477
f(x) = 30.
Table 2 is the inverse of table 1. For Table I, we have that when x = 1.301, f(x) = 20, hence for table 2, we have that f(x) = 1.301 when x = 20.

Which of the following would have resulted in a violation of the conditions for inference? (a) If the entire sample was selected from one classroom (b) If the sample size was 15 instead of 25 (c) If the scatterplot of x = foot length and y = height did not show a perfect linear relationship (d) If the histogram of heights had an outlier (e) If the standard deviation of foot length was different from the standard deviation of height
A perfect linear relationship is essential for making accurate inferences in regression analysis. If the relationship between the variables is not linear, the results from the analysis may not be valid or reliable.
Option (a) would have resulted in a violation of the conditions for inference, as it would not be a representative sample of the population. Inference relies on the sample being representative of the population, and selecting the entire sample from one classroom would not be a random selection from the population.
Options (b), (c), (d), and (e) do not necessarily violate the conditions for inference. The sample size of 15 may affect the precision of the estimate, but it does not necessarily violate the conditions for inference.
A perfect linear relationship is essential for making accurate inferences in regression analysis. The scatterplot not showing a perfect linear relationship is expected in most cases, as perfect linear relationships are rare in real-world data. The histogram having an outlier may affect the distribution, but it does not necessarily violate the conditions for inference. And the standard deviation of foot length is different from the standard deviation of height is expected, as they are measuring different variables.

a box has a volume of 140 cm Square if its breadth is 5 cm and it's length is 7 cm find it's height
Answer:
To find the height of the box, we need to use the formula for volume of a box: Volume = length x breadth x height
Given the values for length and breadth, we can substitute them into the formula and solve for height: 140 = 7 x 5 x height
Simplifying the equation, we get: 140 = 35 x height
Dividing both sides by 35, we get: height = 4
Therefore, the height of the box is 4 cm
