we can found it by using algebra.This checks out, so we can conclude that Simone has:
4 $100 bills
5 $50 bills
2 $20 bills
9 $10 bills

And the total amount of money she has is indeed $780.Let's start by using algebra to represent the information given in the problem. Let:

x = 20 (Simone has 20 bills in total)
h = x/5 (One fifth of the bills are hundreds)
f = x/4 (One fourth of the bills are fifties)
t = x/10 (One tenth of the bills are twenties)
n = x - h - f - t (The rest of the bills are tens)
We also know that the total amount of money Simone has is $780. We can use this information to write an equation:
100h + 50f + 20t + 10n = 780

Now we can substitute the values we found for h, f, t, and n in terms of x:

100(x/5) + 50(x/4) + 20(x/10) + 10(x - x/5 - x/4 - x/10) = 780

We can see that the number of bills must be a whole number, and therefore x must be a multiple of 20. Let's try assuming that Simone has 20 bills of each denomination, which would give us:

h = x/5 = 4 (4 hundreds)
f = x/4 = 5 (5 fifties)
t = x/10 = 2 (2 twenties)
n = x - h - f - t = 9 (9 tens)
Using these values in the algebraic  equation we derived earlier, we get:
100(4) + 50(5) + 20(2) + 10(9) = 780.

Simone has 20 bills. One fifth of the bills are hundreds, 1/4 of them are fifties, 1/10 of them are $20s. The rest of the bills are tens.

the probability that the average age of a randomly selected sample of 100 students will be less than 21.8 years is 0.0564 rounded to three decimal places. The final answer is 0.056.

The problem given can be solved by using the central limit theorem.

According to the central limit theorem, if the sample size is sufficiently large, then the sample mean will follow a normal distribution with a mean of μ and a standard deviation of σ/√n, where n is the sample size.Using this formula, we can find the probability that the average age of a randomly selected sample of 100 students will be less than 21.8 years. The formula is:

P(Z < (X-μ)/(σ/√n))

where Z is the standard normal distribution, X is the value we want to find the probability for, μ is the population mean, σ is the population standard deviation, and n is the sample size.

In this case, X = 21.8, μ = 22, σ = 2, and n = 100. Plugging these values into the formula, we get:

P(Z < (21.8-22)/(2/√100)) = P(Z < -1.58)

Using Excel or a standard normal distribution table, we can find that the probability of Z being less than -1.58 is 0.0564.

According to the given information we can conclude that Richard paid $123.90 for the car rental.

To solve this problem, we need to calculate the total cost of the car rental based on the daily rate and the mileage charge.

First, we can calculate the cost of the rental for two days by multiplying the daily rate by the number of days:

2 days x $34.95 per day = $69.90

Next, we need to calculate the cost of the mileage charge. To do this, we can multiply the number of miles driven by the mileage rate:

300 miles x $0.18 per mile = $54.00

Finally, we can find the total cost of the car rental by adding the cost of the rental and the cost of the mileage charge:

$69.90 + $54.00 = $123.90

Therefore, Richard paid $123.90 for the car rental.

Step-by-step explanation:

The formula to calculate the volume of a cylinder is:

V = πr^2h

where π is a constant equal to 3.14, r is the radius of the cylinder (which is half of the diameter), and h is the height of the cylinder.

To use Maria's expression, we can first calculate the radius of the cylinder:

diameter = 10 1/2 ft

radius = diameter/2 = 5 1/4 ft

Next, we can substitute the values of π and h into the expression 2ℎ:

2ℎ = 2(4 2/5 ft) = 8 4/5 ft

This expression represents the height of the water in the cylinder when it is filled to capacity. To find the volume of water that can fit in the pool, we can substitute the values of π, r, and h into the formula for the volume of a cylinder:

V = πr^2h = 3.14 × (5 1/4 ft)^2 × 8 4/5 ft ≈ 581.8 ft^3

Rounding to the nearest cubic foot, the approximate volume of water that Maria determined can fit into the pool is 582 cubic feet.

The correct system of equations that could be used to find x, the cost of a medium drink, and y, the cost of a large popcorn, is:

A) 2x + y = 13.85 3x + 2y = 23.9

To arrive at these equations, you can use the information given in the question to set up a system of linear equations. You know that 2 medium drinks and a large popcorn cost $13.85, so you can write:

2x + y = 13.85

where x is the cost of a medium drink and y is the cost of a large popcorn.

You also know that 3 medium drinks and 2 large popcorns cost $23.90, so you can write:

3x + 2y = 23.9

Then , you can solve the system of equations for x and y using any method you prefer, such as elimination or substitution. For example, one way to solve the system is to multiply the first equation by 3 to eliminate y:

6x + 3y = 41.55

Then you can subtract the second equation from this equation:

6x + 3y - (3x + 2y) = 41.55 - 23.9

Simplifying this equation gives:

3x + y = 17.65

You now have two equations to solve for x and y:

3x + y = 17.65 3x + 2y = 23.9

This system of equations is equivalent to the system shown in answer A.

Answer:

A

Step-by-step explanation:

The answer is (A) because, first off you have 2 medium drinks. So that is 2x. Second you only have 1 large popcorn. So that is just y. Right now the equation is 2x + y =$13.85. The next part of the problem is the same thing. You have only 1 more medium drink this time, so it is 3x. Then you have 1 more large popcorn, so that is 2y. The final part of the equation is 3x + 2y =$23.90. Since 23.90 is just a decimal you can just get rid of the 0. Now the equation should look like this, 2x + y=$13.85

3x + 2y=$23.9

Answer:
the translated point A' has coordinates (1,9).
Explanation:
To translate the point A(2,7) by the rule (x,y) → (x-1, y+2), we can apply the rule to the x-coordinate and the y-coordinate separately. Subtracting 1 from the x-coordinate and adding 2 to the y-coordinate will give us the new coordinates of the translated point.

Using this rule, we have: A'(x,y) = (2-1, 7+2) = (1, 9)

Therefore, the translated point A' has coordinates (1,9).

To get the answer, we applied the given rule to the x and y coordinates of the point, separately. In other words, we substituted x = 2 and y = 7 into the expressions x-1 and y+2, respectively, to obtain the new x-coordinate and the new y-coordinate.

So, the sophisticated answer is that to translate a point by a given rule, you apply the rule to each coordinate separately, and then combine the results to form the coordinates of the translated point.

110,664,000 possible selections for Head Girl, Deputy Head Girl, Head Boy, and Deputy Head Boy from a group of 101 girls and 105 boys.

How to calculate different possible selections could be made?​

To find the number of possible selections that can be made, we need to multiply the number of choices available for each position.

For the Head Girl position, there are 101 girls to choose from. After one girl is selected for Head Girl, there are 100 girls remaining to choose from for the Deputy Head Girl position. So there are a total of 101 x 100 = 10,100 possible combinations of girls that can be chosen for these two positions.

Similarly, there are 105 boys to choose from for Head Boy, and 104 boys remaining to choose from for Deputy Head Boy. So there are a total of 105 x 104 = 10,920 possible combinations of boys that can be chosen for these two positions.

To find the total number of possible selections, we multiply the number of combinations for the girls by the number of combinations for the boys:

10,100 x 10,920 = 110,664,000

Therefore, there are 110,664,000 different possible selections that could be made.

The answer of question no. 3 is the polygon has 18 sides.

A polygon is a two-dimensional geometric figure that is defined by a closed path of straight line segments. The segments, called sides, intersect at their endpoints, called vertices, and the angles formed by adjacent sides are called interior angles.

Polygons can have any number of sides, but they must have at least three sides (and therefore, three vertices). The most common polygons are the triangle (three sides), quadrilateral (four sides), pentagon (five sides), hexagon (six sides), heptagon (seven sides), octagon (eight sides)

For any polygon, the sum of the exterior angles is always 360 degrees. Therefore, if one exterior angle of a polygon is 20 degrees, then the polygon must have:

360 / 20 = 18 sides.

Therefore, the polygon has 18 sides.

The standard error of the mean is approximately 19.

The standard error of the mean (SEM) can be calculated using the following formula:

SEM = σ / sqrt(n)

where σ is the population standard deviation, n is the sample size, and sqrt() denotes the square root.

Since the population standard deviation (σ) is not given, we can estimate it using the sample standard deviation (s) as follows:

σ ≈ s

Therefore, the formula for SEM can be rewritten as:

SEM ≈ s / sqrt(n)

Substituting the given values, we get:

SEM ≈ 190 / sqrt(100)

= 190 / 10

= 19

So the standard error of the mean is approximately 19.

The standard error of the mean measures the variability of the sample means around the population mean. It is the standard deviation of the sampling distribution of the mean, and it represents the amount of error that can be expected when using the sample mean as an estimate of the population mean.

To calculate the SEM, we need to know the population standard deviation or estimate it using the sample standard deviation. Since we only have the sample standard deviation in this case, we use it as an estimate of the population standard deviation. Then, we apply the formula for SEM and simplify it to obtain the final answer.

Required function is f(x) = 2x-3.

What is function?

In mathematics, a function is a rule or a set of rules that assigns a unique output value to each input value. In other words, it is a way of relating one quantity to another. Functions are used in a variety of fields, such as engineering, physics, economics, and computer science, to describe relationships between variables.

An example of a function is the quadratic function f(x) = x² + 2x + 1. This function takes an input value x and produces an output value that is the result of squaring x, multiplying it by 2, and adding 1. For instance, if we substitute x = 3 in the function, we get:

f(3) = 3² + 2(3) + 1 = 9 + 6 + 1 = 16

To determine which function represents the data in the table, we need to substitute the given values of x into each function and compare the results with the corresponding values of f(x) given in the table.

If we use the function f(x) = 2x-3, we get:

f(0) = -3

f(1) = -1

f(2) = 1

f(3) = 3

f(4) = 5

f(5) = 7

We can see that these values match with the values given in the table, so the function that represents the data in the table is:

f(x) = 2x-3.

Therefore, we can conclude that the function f(x) = 2x-3 represents the data in the table.
