Step-by-step explanation:

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

Hence , the volume of the pyramid is 400 cm³

the probability that there is at least one person who wins no games.

P( A1 ∪ A2 U A3 ) = 16/81 + 16/81 + 16/81 - 1/81 - 1/81 - 1/81 - 0 = 5/9

Number of players = 3

number of times game is repeated = 4

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

Note : each player has equal chance of winning

Find the probability that there is at least one person who wins no games

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 )

where

P( A1 ∩ A2 ) = P( A1 wins all games )

P ( A1 wins all games in 4 attempts ) = ( 1/3 )^4 = 1/81

P( A1 ∩ A2 ∩ A3 ) = P ( no players wins any game in 4 attempts ) = 0

Hence

The values of x in the circles and secant lines are 2.3, 4 and 1

To calculate x, we make use of the tangent-secant line theorem which stated that

c² = b * d

Using the above as a guide, we have the following:

Shape (10)

(14 + x + 2) * 14 = 16^2

This gives

16 + x = 18.3

Collect and evaluate the like terms

x = 2.3

Shape (11)

(4x + 9) * 9 = 15^2

This gives

4x + 9 = 25

Collect and evaluate the like terms

x = 4

Shape (12)

x * (x + 8) = 3^2

The value of P(1.41 < Z < 2.85)  is 0.0771.

Hence, the correct answer is d.

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.

The probability that a standard normal random variable Z is between 1.41 and 2.85 can be found using a standard normal table with a standard normal cumulative distribution function.

The answer is approximate:

P(1.41 < Z < 2.85)

= P(Z < 2.85) - P(Z < 1.41)

= 0.9927 - 0.9185

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.

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,

Step-by-step explanation:

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.

assuming its a right triangle 30 deg with sides being 9 3 10 and angles being 30 60 90

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

The correct option is A) No, because the center of a distribution and the spread are not related

The standard deviation is a measure of the spread or dispersion of a set of data. It is not directly related to the mean or average of the data.

The standard deviation is calculated based on the deviations of each data point from the mean, taking into account how many data points there are.

The mean does not affect the calculation of the standard deviation, as the formula for standard deviation is based solely on the data itself and not on any summary statistics like the mean.

The value of the standard deviation can remain the same even if the mean changes, and conversely, the mean can change without affecting the standard deviation.

Thus, option A) No, because the center of a distribution and the spread are not related is correct.
