suppose George has three pieces of wood to use for a triangular frame for his art piece the pieces of wood have length of 16 inch 14 inch 30-in can George use these pieces of wood to make a triangular frame​

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.

Answer:

Step-by-step explanation:

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.

a. Based on the chi-squared goodness of fit test, we do not have enough evidence to conclude that mice show a preference towards one paw over the other, with a calculated chi-squared value of 2.5 and a critical value of 3.84 at a significance level of 0.05.

b. The problem with repeating the analysis from part (a) with the new dataset of 480 observations is that the data is no longer independent due to repeated measures. A different statistical test that takes into account repeated measures, such as a repeated measures ANOVA, would need to be used to properly analyze this new dataset.

a. To test whether the data suggests that mice show a preference towards one paw over the other, we can use a chi-squared goodness of fit test. The null hypothesis for this test is that there is no preference towards one paw over the other, while the alternative hypothesis is that there is a preference towards one paw over the other.

The observed frequencies are

Right paw: 18 mice

Left paw: 30 mice

We can calculate the expected frequencies assuming no preference using the formula:

Expected frequency = (total number of observations * probability of right paw use) or (total number of observations * probability of left paw use)

Expected frequency of right paw use = 48 * 0.5 = 24

Expected frequency of left paw use = 48 * 0.5 = 24

We can now calculate the chi-squared test statistic using the formula:

chi-squared = sum((observed frequency - expected frequency)^2 / expected frequency)

Substituting the observed and expected frequencies into the formula:

chi-squared = ((18 - 24)^2 / 24) + ((30 - 24)^2 / 24) = 2.5

Using a chi-squared distribution table with one degree of freedom and a significance level of 0.05, the critical value is 3.84.

Since the calculated chi-squared value (2.5) is less than the critical value (3.84), we fail to reject the null hypothesis. Therefore, we do not have enough evidence to conclude that mice show a preference towards one paw over the other.

b. The problem with repeating the analysis from part (a) with the new dataset of 480 observations is that the data is no longer independent. Since each mouse was observed 10 times, the observations for each mouse are not independent, and treating them as such would violate the assumptions of the chi-squared goodness of fit test. To properly analyze this new dataset, a different statistical test that takes into account repeated measures, such as a repeated measures ANOVA, would need to be used.

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.

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

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.

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)

1. The length of the fence required to enclose the circular pool with 4 feet of space around it is approximately 125.6 feet.

2.  If he runs around the track once he will still can't complete the goal he needs to run 20 more meters to meet his daily goal. Option A is the correct choice.

1.  To find the length of the fence required to enclose a circular swimming pool with a radius of 20 feet and a 4-foot space around it, we need to first calculate the diameter of the pool plus the space around it.

The diameter of the pool is twice the radius, which is 40 feet.

Adding 4 feet of space on both sides of the diameter gives us a total diameter of 48 feet.

The fence will be installed around the perimeter of this circular area, which is the circumference of the circle.

To calculate the circumference, we use the formula

C = 2πr

where C is the circumference, π is approximately 3.14, and r is the radius of the circle.

Plugging in the values, we get:

C = 2 x 3.14 x 20 feet = 125.6 feet.

2.

To calculate the distance around the swimming pool, we first need to find the total length of the semicircles, which is equal to half the circumference of a circle with a diameter of 35 meters.

The formula for the circumference of a circle is

C = πd

where C is the circumference and d is the diameter.

Plugging in the values, we get:

C = π x 35 meters / 2 = 54.99 meters

The total length of both semicircles is twice the length of one semicircle, which is

2 x 54.99 meters = 109.98 meters.

The length and width of the rectangular part of the pool are 80 meters and 35 meters, respectively.

Therefore, the distance around the rectangular part is

2 x (80 + 35) meters = 230 meters.

Adding the length of the semicircles to the length of the rectangle, we get the total distance around the swimming pool, which is

109.98 meters + 230 meters = 339.98 meters.

Therefore, Kevin needs to run at least 340 meters to meet his daily goal of 320 meters.

Since one lap around the high school track is only 320 meters, Kevin will need to run an additional 20 meters to meet his daily goal.

Thus, the correct answer is: option A "No, he will still need to run 20 more meters."

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:

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.
