He is over budget by $1,333.33 - $800 = $533.33 per month.

Budget can be defined as a financial plan that outlines expected income and expenditures for a specific period of time, usually a month or a year. It is a tool used to manage personal to ensure that there is enough money coming in to cover all of the necessary expenses and to prioritize spending in a way that aligns with one's financial goals.

Budget helps to track and control spending, identify areas where expenses can be reduced and make adjustments as needed to stay on track.

If he gives away 60% of his budget, then his monthly budget is $800 / 0.6 = $1,333.33.

So, he is over budget by $1,333.33 - $800 = $533.33 per month.

The surface area of the triangular prism is 270 ft².

The surface area of a triangular prism is the sum of the areas of all 5 faces. To find the area of the triangle, you can use the formula:

A = (B × h) ÷ 2, where B is the base and h is the height.

To find surface area of triangular prism we can calculate each area of all faces :

A1 = 13 × 7 = 91 ft²

A2 = 12 × 7 = 84 ft²

A3 = 5 × 7 = 35 ft²

A4 = (12 × 5) ÷ 2 = 30 ft²

A4 = (12 × 5) ÷ 2 = 30 ft²

Surface Area = A1 + A2 + A3 + A4 + A5

Surface Area = 91 + 84 + 35 + 30 + 30

Surface Area = 270 ft²

The volume of the pyramid is given by the equation V = 400 cm³

The volume of a pyramid, is the product of the area of its base with the height of the pyramid, and divide by 3. We express this product with the formula V = ( 1/3) ×B×h, where B is the area of the base of the pyramid, and h is its height.

Volume of Pyramid = ( 1/3 )a²H

Given data ,

Let the volume of the pyramid be represented as V

Now , the equation will be

The height of the pyramid H = 12 cm

The base side length of the pyramid a = 10 cm

So , Volume of Pyramid = ( 1/3 )a²H

Substituting the values in the equation , we get

Volume of Pyramid V = ( 1/3 ) x 10² x 12

Volume of Pyramid V = 4 x 100

Volume of Pyramid V = 400 cm³

a. The number of passengers for each cruise line in thousands:

4,133,000 passengers ÷ 1,000 = 4,133 passengers

2,369,000 passengers ÷ 1,000 = 2,369 passengers

1,295,000 passengers ÷ 1,000 = 1,295 passengers

928,000 passengers ÷ 1,000 = 928 passengers

679,000 passengers ÷ 1,000 = 679 passengers

So, the answer is 4,133; 2,369; 1,295; 928; 679.

b. The mean number of passengers can be found by adding the number of passengers for each cruise line and then dividing the total by the number of cruise lines, which is 5.

(4,133 + 2,369 + 1,295 + 928 + 679) ÷ 5 = 10,514 ÷ 5 = 2,102.8 passengers

So, the mean number of passengers is 2,102.8 passengers.

c. The range is the difference between the highest and lowest number of passengers, which is:

4,133 - 679 = 3,454 passengers

So, the range is 3,454 passengers.

d. The standard deviation can be calculated using the formula for the standard deviation of a sample. However, this calculation is quite complex and requires a significant amount of mathematical knowledge and computational resources. Without access to those resources, the standard deviation cannot be calculated

The standard deviation is a measure of the amount of variation or dispersion from the mean. It shows how spread out the values in a set of data are. To calculate the standard deviation, the difference of each value from the mean is squared and then divided by the number of items in the set. The standard deviation provides a way to quantify the degree of variation of the values around the mean. It is a useful tool for understanding how much each value in a set deviates from the average.

Time taken to have both planes at same altitude = 1.2 seconds.

Relative speed can be defined as the speed of a moving body with respect to another. When two bodies move in the same direction, their relative speed is computed by their difference. But when two bodies are moving in the opposite direction, the relative speed is calculated by adding the speed of both the bodies.

Given,

Plane A is at altitude of 3329 feet.

Plane B is at altitude of 4000 feet

Plane A is gaining altitude at Distance between them

= 4000 - 3329 feet

= 671 feet

Speed of plane A = 605 feet per second.

Speed of plane B = 45.25 feet per second

Since both plane are moving upwards

Relative speed = 605 - 45.25 = 559.75 feet per second

Time of both planes to be on same altitude

= 671/559.75

= 1.198 seconds.

≈ 1.2 seconds.

Hence, it will take 1.2 seconds to have both planes at same altitude.

The monthly payment to the nearest cent is $1381.51,

The total of all monthly payments over the 30 years is $497,343.6,

and her total interest for the 30 years is $284,343.6.

The amount that the lender charges the borrower over and beyond the principal amount is referred to as the interest rate. A person who deposits money in a bank or other financial institution also earns additional income in terms of the recipient, known as interest, taking into account the time value of money.

Given amount borrowed = $213,000

time period = 30 years

interest rate = 6.75% = 0.0675

to find the monthly payment,

so M = [tex]\frac{p(\frac{r}{n} )(1 + \frac{r}{n} )^{nt}}{(1 + \frac{r}{n} )^{nt} - 1}[/tex]

here n = 12 for the monthly payment

M = monthly payment

p = principal

t = time =  30 years

r = trate = 0.0675

p = $213000

so 1 + r/n = 1 + 0.0675/12

1 + r/n =  1.005625

M = [213000(0.005625)(1.00625)³⁶⁰] ÷ [(1.00625)³⁶⁰ - 1]

M = $1381.51

B:  What's the total of all monthly payments over the 30 years,

there will be 360 payments in 30 years,

a total amount of 360 payments = $1381.51*360

a total amount of 360 payments = $497,343.6

C: What's her total interest for the 30 years

total interest in 30 years = $497,343.6 - $213000

total interest in 30 years = $284,343.6.

Hence monthly payment is  $1381.51,

total of all monthly payments is $497,343.6,

The sum of an infinite geometric series is given by a+ar+ar^2  where a is the first term and r is the common ratio.

The sum of the series  can be represented by :

a / ( 1 - r)  = 12

a = 12 ( 1- r )    (1)

So....note that the sum of the  terms  with odd powers of r  can be represented by :

ar  + ar^3  + ar^5 + ar^7 +  ..... + ar^(2n - 1)  =  5   (2)

And note that the sum of the  terms  with even powers of r  can be represented by :

a  +  ar^2  + ar^4 + ar^6 + ar^8 +  ..... + ar^(2n)  =  7   (3)

Multiply (2)  by r on both sides

ar^2  + ar^4  + ar^6 + ar^8 +  ..... + ar^(2n )  =  5r     (4)

Subtract   (4)  from (3)

a  = 7 - 5r    (5)

7 - 5r  = 12(1 - r)

7 - 5r  =  12 - 12r

a. To create a quadratic equation that models the arrow's height, we need to find the coefficients of the equation that best fit the data. One common method is to use a least squares regression to fit the data to a quadratic equation in the form y = ax^2 + bx + c. There are several ways to perform this regression, but one common method is to use a spreadsheet program or a graphing calculator with regression capabilities.

b. Based on the quadratic equation that models the arrow's height, we can predict the height of the arrow at any distance from the archer. If Coach Deline is 500 feet away from the archer, we can plug 500 into the equation as x and find the corresponding y value. If the y value is greater than 0, then the arrow is still in the air and has not hit the ground. If the y value is equal to 0, then the arrow has hit the ground. If the y value is less than 0, then the arrow has hit the ground and passed it. Based on this information, we can determine if the arrow will hit Coach Deline or not.

P( any person wins a game ) = 1/3

P ( any person does not win a game ) = 1 - 1/3 = 2/3

P ( any person wins no game in 4 attempts ) = ( 2/3 )^4 = 16/81

lets represent the probability of each player not wining a game with alphabet A

A1 = player 1 wins no game

A2 = player 2 wins no game

A3 = players 3 wins no game

Applying the inclusion-exclusion formula

P( A1 ∪ A2 U A3 ) = P(A1 ) + P(A2) + P(A3) - P( A1 ∩ A2 ) - P( A2 ∩ A3 ) - P( A1            ∩ A3 )  + P( A1 ∩ A2 ∩ A3 )

A normally distributed random variable with mean μ= 0 and standard deviation σ= 1 is referred to as a standard normal random variable. The letter Z will always be used to represent it.

Because the Standard Normal Distribution is a probability distribution, the area under the curve between two points indicates the likelihood that variables will take on a range of values.

The whole area under the curve is one, or one hundred percent.

The mean and variance of a normal distribution are governed by two factors.

A standard normal distribution is a normal distribution with a mean of 0 and a standard deviation of 1.
