Answer:

-20% discount

Step-by-step explanation:

subtract the two numbers:

1020-1360= -340 (is a percentage reduction, so I have to subtract the larger number from the smaller one)

divide the result by the original value:

-340÷1360= -0,25

to turn it into a percentage, multiply it by 100:

-0,25×100= -25%

Hope it helps!

Answer:

there's a decrease of 25%

or

-25%

Step-by-step explanation:

100% = 1360

___% = 1020

\( \frac{1020 \times 100}{1360} = 75\)

100- 75= 25%

The data set  0, 2, 5, 8, and 10 have a higher standard deviation but the same mean.

The average distance between each data item and the mean is known as the mean absolute deviation.

The gap between each data value and the mean in absolute terms is represented by this average.

The given data set is 2, 2, 5, 8, 8.

Now, The standard deviation has other uses than serving as a measurement for the normal distribution. It is more commonly used as a measure of spread.

To have a greater standard deviation the data should have more differences from each other.

Therefore, 0, 2, 5, 8, 10 have the same mean but greater standard deviation.

The correct answer is option (A) TH. The diameter of the circle shown in the diagram is TH

A diameter is a straight line that passes through the center of the circle and connects two points on the circle.

Therefore, in order to find the diameter of a circle, we need to identify two points on the circumference that are opposite to each other.

These two points form the endpoints of the diameter of the circle.

The given circle is shown below: As we can see from the diagram, points H and T lie on the circumference of the circle, and they are opposite to each other.

Hence, the line TH is the diameter of the circle.

Step-by-step explanation:

Use the properties of degrees:

1)

\( {( \frac{1}{108} })^{3} = \frac{ {1}^{3} }{ {108}^{3} } = \frac{1}{6561} \)

\( \frac{1}{6561} ≠ \frac{1}{36} \)

Hello!

the sum of the angles in the triangle = 180°

so the 3rd angle = 180° - 165° = 15°

The solution to the nonlinear system of equations is (x, y) = (-3, -2) and (x, y) = (1, 6). These points represent the coordinates where the two equations intersect and satisfy both equations simultaneously.

To solve the nonlinear system of equations:

Equation 1: \(y = -x^2 + 7\)

Equation 2: y = 2x + 4

We can equate the right sides of both equations since they both represent y.

\(-x^2 + 7 = 2x + 4\)

To simplify the equation, we can rearrange it to be in the standard quadratic form:

\(x^2 + 2x - 3 = 0\)

Now, we can solve this quadratic equation by factoring, completing the square, or using the quadratic formula. In this case, let's use factoring:

(x + 3)(x - 1) = 0

From this equation, we get two possible solutions:

x + 3 = 0 => x = -3

x - 1 = 0 => x = 1

Now, we substitute these x-values back into either equation to find the corresponding y-values.

For x = -3:

y = 2(-3) + 4

y = -6 + 4

y = -2

For x = 1:

y = 2(1) + 4

y = 2 + 4

y = 6

Based on the data recorded by Anna on Saturday, we can estimate the number of people expected to visit The Youth Wing on Sunday.

Let's calculate the proportion of visitors to The Youth Wing compared to the total number of visitors on Saturday:

\(\displaystyle \text{Proportion} = \frac{\text{Visitors to The Youth Wing on Saturday}}{\text{Total visitors on Saturday}} = \frac{382}{382 + 461 + 355}\)

Next, we'll apply this proportion to the total number of visitors on Sunday to estimate the number of people expected to go to The Youth Wing:

\(\displaystyle \text{Expected visitors to The Youth Wing on Sunday} = \text{Proportion} \times \text{Total visitors on Sunday}\)

Now, let's substitute the values into the equation and calculate the estimated number of visitors to The Youth Wing on Sunday:

\(\displaystyle \text{Proportion} = \frac{382}{382 + 461 + 355}\)

\(\displaystyle \text{Expected visitors to The Youth Wing on Sunday} = \text{Proportion} \times 800\)

Calculating the proportion:

\(\displaystyle \text{Proportion} = \frac{382}{382 + 461 + 355} = \frac{382}{1198}\)

Calculating the estimated number of visitors to The Youth Wing on Sunday:

\(\displaystyle \text{Expected visitors to The Youth Wing on Sunday} = \frac{382}{1198} \times 800\)

Simplifying the equation:

\(\displaystyle \text{Expected visitors to The Youth Wing on Sunday} \approx \frac{382 \times 800}{1198}\)

Now, let's calculate the approximate number of visitors to The Youth Wing on Sunday:

\(\displaystyle \text{Expected visitors to The Youth Wing on Sunday} \approx 254\)

Therefore, based on the data recorded on Saturday, we can estimate that around 254 people should be expected to go to The Youth Wing on Sunday.

You need to find how many cups of hot chocolate skaters bought last weekend. Start with the information in the problem.

Skaters bought 126 cups of hot chocolate, apple cider, or coffee in all.

They bought twice as many cups of hot chocolate as cups of apple cider.

They bought 3 times as many cups of coffee as cups of apple cider.

You can use a diagram to model the problem. Skaters bought the fewest number of cups of apple cider, so start with apple cider.

Skaters bought twice as many cups of hot chocolate as cups of apple cider. So, draw 1 box to represent the number of cups of apple cider and 2 boxes to represent the number of cups of hot chocolate.

apple cider

hot chocolate

coffee

Skaters bought 3 times as many cups of coffee as cups of apple cider. There is 1 box for apple cider. So, draw 3 boxes to represent the number of cups of coffee.

apple cider = 1 box

hot chocolate = 2 box

coffee = 3 box

There are 6 boxes in the diagram in all. Skaters bought a total of 126 cups of hot chocolate, apple cider, or coffee. So, each box represents 126÷6 cups. Divide.

Answer:

the correct answer is D) {0, 1, 2, 3, 4, 5}.

Step-by-step explanation:

The union of two sets is a set that contains all the elements that are in either set, without any duplicates.

In this case, we have X = {0, 1, 3} and Y = {2, 4, 5}. So, X | Y means we take all the elements that are in set X and all the elements that are in set Y, and put them together in a single set.

When we do this, we get:

X | Y = {0, 1, 3} | {2, 4, 5}

= {0, 1, 2, 3, 4, 5}

So, the set X | Y contains all the elements that are in X and all the elements that are in Y, which is {0, 1, 2, 3, 4, 5}.

The equation that represents a quadratic relationship is y = 4x^2. Option A.

A quadratic relationship is a mathematical relationship where the variable y is a function of the variable x raised to the power of 2. In other words, it is an equation in which the highest power of the variable is 2.

Let's analyze the given equations:

1. y = 4x^2: This equation represents a quadratic relationship because the variable x is raised to the power of 2. The term 4x^2 indicates that the relationship between x and y is quadratic.

2. y = 4x^4: This equation represents a quartic relationship, not a quadratic relationship. The variable x is raised to the power of 4, which indicates a higher degree relationship than quadratic.

3. y = 4x^3: This equation represents a cubic relationship, not a quadratic relationship. The variable x is raised to the power of 3, indicating a higher degree relationship.

4. y = 4: This equation represents a linear relationship, not a quadratic relationship. It is a constant equation where y is always equal to 4, regardless of the value of x. In a quadratic relationship, the variable x should have a power of 2. Option A.

15/25 = 0.6

0.6 = 60%

Answer:

$336

Step-by-step explanation:

20% can be split into 2 10%

so to find 10% of a number U move the decimal point 1 place left

so 10% of 250 = 25, therefore 20% must equal

25 + 25 = 50. 20% of 250 is 50

and by doing the same this we find that 20% of 170 is 34

now minus the percentage from the original tO get the new price of both items

\(250 - 50 = 200\)

\(170 - 34 = 136\)

now add both 136 and 200 together to get the price she will pay for both on sale

\(200 + 136 = 336\)

The probability that the song will be played on exactly 2 days out of 5 days is approximately 0.164.

To find the probability that a particular song is played exactly 2 days out of 5 days at radio station WMZH, we can use the binomial probability formula.

The binomial probability formula is given by P(x) = C(n, x) * p^x * (1-p)^(n-x), where P(x) is the probability of x successful outcomes, n is the number of trials, p is the probability of a successful outcome on a single trial, and C(n, x) represents the binomial coefficient, which is the number of ways to choose x items from a set of n items.

In this case, we want to find the probability of the song being played exactly 2 days out of 5 days, so x = 2, n = 5, and p = 3/8.

Using the formula, we have:

P(2) = \(C(5, 2) * (3/8)^2 * (1 - 3/8)^(^5^-^2^)\)

C(5, 2) = 5! / (2! * (5-2)!) = 10

P(2) = 10 * (3/8)^2 * (5/8)^3

P(2) ≈ 0.164 (rounded to three decimal places)
