Answer:

1. $1500

2. 15lb

Step-by-step explanation:

just subtract them

The probability that they both are green is 13.22%. If the selection is done with replacement, then the probability of selecting a green M&M on the first draw is 4/11 (since there are 4 green out of 11 total M&Ms).

The probability of selecting another green M&M on the second draw is also 4/11, since the first M&M is replaced before the second selection is made, so the number of green and blue M&Ms remains the same. Therefore, the probability of selecting two green M&Ms with replacement is the product of the probabilities of selecting a green M&M on the first and second draws:

P(two green with replacement) = P(green on first draw) * P(green on second draw)
= (4/11) * (4/11)
= 16/121
≈ 0.1322
or about 13.22%.

The value of x for the given expression is 576xyz² - 960xy + 6624y + 552x²yz² - 920x²y + 5068z² - 8460y + 1152.

To find the value of x for the given expression (8x - 7)(3x - 11)(2y + 23) (3z2 - 5)(4y + 8), we need to first simplify the expression using the distributive property of multiplication.

Here's how: First, we can combine the terms inside the first set of parentheses: (8x - 7)(3x - 11) = 24x² - 104x + 77. Next, we can multiply this result by the second set of parentheses: (24x² - 104x + 77)(2y + 23) = 48xy + 552y + 46x²y + 529

Next, we can multiply this result by the third set of parentheses: (48xy + 552y + 46x²y + 529)(3z² - 5) = 144xyz² - 240xy + 1656y + 138x²yz² - 230x²y + 1267z² - 2115

Finally, we can multiply this result by the fourth set of parentheses: (144xyz² - 240xy + 1656y + 138x²yz² - 230x²y + 1267z² - 2115)(4y + 8) = 576xyz² - 960xy + 6624y + 552x²yz² - 920x²y + 5068z² - 8460y + 1152. Now, we can set this result equal to x and solve for x:576xyz² - 960xy + 6624y + 552x²yz² - 920x²y + 5068z² - 8460y + 1152 = x

Therefore, the value of x for the given expression is 576xyz² - 960xy + 6624y + 552x²yz² - 920x²y + 5068z² - 8460y + 1152.

Option B, (x, y) -> (-x, y), does not preserve congruence.

Congruence is a geometric relationship between two figures that have the same size and shape. In other words, two figures are congruent if one can be superimposed on the other without any overlapping or gaps.

A transformation preserves congruence if the image of a congruent figure is also congruent to the original figure. Option B, (x, y) -> (-x, y), reflects the figure over the y-axis, so it changes the orientation of the figure and therefore does not preserve congruence.

Options A, ( x, y) -> ( x + 6, y + 6), C, (x, y) -> (6x, 6y), and D, (x, y) -> (-y, x), all preserve congruence.

Let p = 0.2 be the probability of a ticket holder failing to show up. Then, the probability of a ticket holder showing up is q = 1 - 0.2 = 0.8. Given that the airline wants to be 99% confident that all ticket holders who do show up will be able to board the plane, we want to find the maximum number of tickets that the airline can sell, such that the probability of more than 400 passengers showing up is no more than 1%.

Solution:

n = the maximum number of tickets that the airline can sell on a flight with 400 seats.

First, we need to check whether the conditions for applying the Central Limit Theorem are satisfied or not. Here, we are dealing with a binomial distribution, which satisfies the following conditions for applying the Central Limit Theorem:

np = 400(0.8)

= 320 ≥ 10nq

= 400(0.2)

= 80 ≥ 10

Since both of the above conditions are satisfied, we can approximate the binomial distribution with a normal distribution with mean

μ = np = 320 and variance σ2 = npq = 64.

The probability of more than 400 passengers showing up is P(X > 400), where X is the number of passengers showing up, which can be approximated by a normal distribution with the same mean and variance. Hence, we need to find the value of n, such that

P(X > 400) = P(Z > (400 - 320 + 0.5)/√64)

= P(Z > 2.37) ≤ 0.01

where Z is the standard normal variable with mean 0 and variance

1. Using the standard normal distribution table, we find that

P(Z > 2.37) = 0.009 is the closest value to 0.01. Therefore, we can set

P(Z > 2.37) = 0.009

in the above equation and solve for n as follows:

2.37 = (n - 320 + 0.5)/8n - 320 + 0.5

= 2.37 × 8n - 319.5 = 18.96n

n ≈ 338.55

≈ 339 (rounded up to the nearest integer)

Therefore, the maximum number of tickets that the airline can sell on a flight with 400 seats is n = 339,

such that it can be approximately 99% confident that all ticket holders who do show up will be able to board the plane. Given that an airline wants to sell as many tickets as possible for a flight, there is always a risk that some ticket holders might not show up on the day of the flight. The airline usually overbooks the flight to compensate for this risk. However, overbooking can lead to inconvenience for passengers, as there might be more passengers than the available seats on the flight. In order to avoid such inconvenience, it is necessary to determine the maximum number of tickets that the airline can sell, such that the probability of more than 400 passengers showing up is no more than 1%.To solve this problem, we used the Central Limit Theorem to approximate the binomial distribution with a normal distribution, since np and nq are both greater than or equal to 10. Using the de Moivre-Laplace 1/2-correction, we found that n = 339 is the maximum number of tickets that the airline can sell on a flight with 400 seats, such that it can be approximately 99% confident that all ticket holders who do show up will be able to board the plane.

Thus the airline can sell a maximum of 339 tickets on a flight with 400 seats, such that it can be approximately 99% confident that all ticket holders who do show up will be able to board the plane.

When events A and B are mutually exclusive or disjoint, the probability of either event A or event B occurring is equal to the sum of their individual probabilities, represented by P(A or B) = P(A) + P(B).

If it is impossible for events A and B to occur simultaneously, the events are said to be mutually exclusive or disjoint.

For mutually exclusive events, the probability of either event A or event B occurring is equal to the sum of their individual probabilities.

Therefore, for mutually exclusive events A and B, the probability of A or B occurring, denoted as P(A or B), is given by:

P(A or B) = P(A) + P(B)

This is because when events A and B are mutually exclusive, they cannot occur together.

Thus, the probability of either event A or event B happening is simply the sum of their individual probabilities.

It is important to note that this statement holds true only for mutually exclusive events.

If events A and B are dependent or not mutually exclusive, we need to consider other factors such as their joint probability and the probability of their intersection.

The approximate internal rate of return on this project is approximately 13.59% at which the present value of the cash inflows (profits) is equal to the initial investment.

To calculate the approximate internal rate of return (IRR) for this project, we need to determine the discount rate at which the present value of the cash inflows (profits) is equal to the initial investment.

Given:

Initial investment = $2,000,000

Annual profit generated = $400,000

Number of years = 7

We can set up the following equation:

PV of cash inflows = Initial investment

To calculate the present value of the cash inflows, we need to discount each year's profit at the discount rate (IRR) and sum them up. Using a financial calculator or spreadsheet software, we can iterate different discount rates until the present value of the cash inflows matches the initial investment. Using an iterative process, the approximate internal rate of return (IRR) for this project is found to be approximately 13.59%.

Function is defined as a type of relation in which one input value is connected with only one output value. Though, one output can have multiple inputs.

The properties of a function are as follows:

- Domain of a function is the input value of the function. Generally, x value is taken as domain or input.

- Range is the output value of the function. It is generally taken as y coordinate.

Domain and range need not always be the same or a subset of one another.

Function always has at least one dependent variable (range) and independent variable (domain).

38x - 5y + 574 = 0

Given, a curve with the points represented by

x = t²-23 and y = t³ + t, at t = 5

we have to find an equation of the line tangent to the curve at the given point on the curve.

so, the given point is (x , y) = (5² - 23 , 5³ + 5)

(x , y) = (2 , 130)

Now, the slope of the curve at that point be,

dy/dx = (3t² + 1)/(2t)

dy/dx = 76/10

Now, on using the slope-intercept form, we get

(y - 130)/(x - 2) = 38/5

5(y - 130) = 38(x - 2)

5y - 650 = 38x - 76

38x - 5y + 574 = 0

Hence, the equation of the line tangent to the curve at the point corresponding to the given value of t.

x = t²-23 and y = t³ + t, at t = 5 is

Answer:

length = 14 metres, width = 12 metres

Step-by-step explanation:

let x be length

length = x

width = x-2

perimeter of parallelogram = 52

length + length + width + width = 52

x+x+x-2+x-2=52

4x-4=52

4x=56

x=14

length = 14 metres

width = 14 - 2 = 12 metres

Answer:

P=2(l+w)

or, 52=2(l+l-2)

or, 52=4l-4

or, 56 =4l

therefore length=14m

therefore breadth=l-2=12m

Answer :-

a) = Let cement, sand and stone in the concrete be x, 2x and 3x,

Each bag of dry concrete is 30 kg,

so,

x + 2x + 3x = 30

or, 6x = 30

so, x = 5

Now,

one bag contaings 2×5 = 10 kg of sand.

He buys just enough sand,stone and cement to make 50 bags of dry concrete,

1 bag = 10 kg sand

50 bags = 10 × 50 kg sand = 500 kg of sand

So,

He buys 500 kg of sand.

b) =

1 bag contains

5 kg of cement, 2×5 = 10 kg of sand and 3×5 = 15 kg of stone,

so,

25 kg of cement = 5.50 euro

5 × 50 kg of cement = 5.50/25 × 250 euro = 55 euro

20 kg of sand = 2 euro

500 kg of sand = 2/20 × 500 euro = 50 euro

15 kg of stone = 3.9 euro

15 × 50 kg = 3.9/15 × 750 euro = 195 euro

Total for 50 bags, he spent 50 + 195 + 55 euro = 300 euro.

He sold it for 396 euro.

His profit percent = (396 - 300)/300 × 100%
