The Spirit Club makes $2.5 profit on each shirt at the end of the year.

What is profit?

Cost price and selling price are better ways to explain profit. Cost price is the actual cost of the good or service, whereas selling price is the price at which it is offered for sale. In this case, the business has made a profit if the selling price of the good is higher than the cost price. Consequently, the profit calculation formula is;

Selling price minus cost price equals profit or gain.

Given that the cost of a shirt for the Spirit Club is $8.

They mark up the shirts 75% to sell in the school store.

The amount that is up on each shirt is $8×75%

= $8×(75/100)

= $8×(3/4)

= $6.

The marked price of each shirt is  $8 + $6 = $14.

They sell the shirts for 25% off at the end of the year.

The discount amount is $14×25%

= $14×(25/100)

= $14×(1/4)

= $3.5

The selling price of each shirt at the end of the year is $14 - $3.5 = $10.5.

The profit is Selling price - cost price = $10.5 - $8 = $2.5

The original price of the hammer from the online retailer is $23.

Percentage is defined as the parts of a number per fraction of 100. We have to divide a number with it's whole and then multiply with 100 to calculate the percentage of any number.

Percentage is usually denoted by the symbol '%'.

Given that,

Discount percentage = 25%

Amount after the discount = $17.25

We have to find the original price of the hammer.

Let x be the original price of the hammer.

x - 25% of x = 17.25

x - 0.25x = 17.25

0.75x = 17.25

x = $23

Hence the original cost of the hammer is $23.

Answer:

Step-by-step explanation:

Let's use A to represent the number of adult tickets sold and C to represent the number of children tickets sold. We can set up two equations based on the information given:

The total number of tickets sold is the sum of adult and children tickets:

A + C = 487

The total proceeds from ticket sales is the product of the number of tickets and their respective prices:

47A + 29C = 17525

We can use the first equation to solve for one of the variables in terms of the other:

C = 487 - A

Substituting this expression for C into the second equation, we get:

47A + 29(487 - A) = 17525

Simplifying and solving for A:

18A + 14123 = 17525

18A = 3402

A = 189

So 189 adult tickets were sold. Using the equation C = 487 - A, we can find the number of children tickets sold:

C = 487 - 189 = 298

Therefore, 189 adult tickets and 298 children tickets were sold for the matinee.

Answer:

0.0376 or 3.76%.

Step-by-step explanation:

The probability of drawing a red marble on the first draw is 5/21 because there are 5 red marbles out of 21 total marbles in the bag.

After the first draw, there are only 20 marbles left in the bag, so the probability of drawing a red marble on the second draw, without replacement, is 4/20 or 1/5.

Similarly, after the second draw, there are only 19 marbles left in the bag, so the probability of drawing a red marble on the third draw, without replacement, is 3/19.

To find the probability of all three marbles being red, we need to multiply the probabilities of each individual draw together:

(5/21) x (1/5) x (3/19) = 15/399 or approximately 0.0376.

Therefore, the probability of drawing three red marbles in a row, without replacement, is about 0.0376 or 3.76%.

How to find Reflection of a point?

When a point is reflected across the X-axis, the x-coordinates remain the same. But the Y-coordinates are transformed into their opposite signs. Therefore, the reflection of the point (x, y) across X-axis is (x, -y).

The reflected point will be equidistant from the point over which it is reflected as the original point and in the same line as the original point and the reflected point.

Find the difference between the x and y values of the given points and add that value (distance) to the reflection point.

x-values: 4-3 = 1   y-values: 0-(-2) = 2

The individual events are overlapping. The probability of the combined event is 11/26.

The individual events are overlapping because there are face cards that are also spades (i.e., the Jack, Queen, and King of Spades). To find the probability of the combined event, we need to add the probability of drawing a face card and the probability of drawing a spade, and then subtract the probability of drawing the Jack, Queen, or King of Spades (since we would be double-counting these cards otherwise).

The probability of drawing a face card is 12/52, since there are 12 face cards in the deck (4 Jacks, 4 Queens, and 4 Kings) out of a total of 52 cards.

The probability of drawing a spade is 13/52, since there are 13 spades in the deck (including the Jack, Queen, and King of Spades) out of a total of 52 cards.

The probability of drawing the Jack, Queen, or King of Spades is 3/52, since there are 3 such cards in the deck out of a total of 52 cards.

Therefore, the probability of the combined event is:

P(face card or spade) = P(face card) + P(spade) - P(Jack, Queen, or King of Spades)

P(face card or spade) = 12/52 + 13/52 - 3/52

P(face card or spade) = 22/52

P(face card or spade) = 11/26

So the probability of the combined event is 11/26 or approximately 0.42 when rounded to two decimal places.

This shows the individual events are overlapping and the probability is 11/26

The value of z in the figure is 56⁰.

What is an angle?

An angle is a figure in plane geometry that is created by two rays or lines that have a common endpoint. The Latin word "angulus," which means "corner," is the source of the English word "angle." The common endpoint of two rays is known as the vertex, and the two rays are referred to as the sides of an angle.

In the given figure, there are two pairs of vertically opposite angles.

The vertical opposite angle of 124⁰ is y⁰.

The vertical opposite angle of x⁰ is z⁰.

Thus, 124⁰ = y⁰ and x⁰ = z⁰.

The sum of all angles is 360⁰.

Therefore,

124⁰ + x⁰ +  y⁰ + z⁰ = 360⁰

Putting y⁰ = 124⁰ and x⁰ = z⁰ in the above equation:

124⁰ + z⁰ + 124⁰ + z⁰ = 360⁰

248⁰ + 2z⁰ = 360⁰

Subtract 248⁰ from both sides:

2z⁰ = 360⁰ - 248⁰

We have discussed what is skewed distribution and how to deal with skewed data as mentioned below.

What is a skewed distribution?

When one tail is longer than the other, the distribution is said to be skewed. The asymmetry of a distribution is defined by skewness. These distributions are asymmetric, in contrast to the well-known normal distribution and its bell-shaped curve. Because the data are not equally distributed on both sides of the distribution peak, the two parts of the distribution are not mirror images.

A) The direction of outliers is revealed by skewness. A distribution curve's tail is longer on the right side when there is a positive skew. As a result, the distribution curve's outliers are more extreme to the right and closer to the mean to the left. Skewness simply conveys the direction of outliers; it does not convey the number of outliers.

B) Lower or upper boundaries on the data frequently cause skewed data. In other words, data with a lower bound are frequently skewed right, whereas data with an upper bound are typically skewed left.

C) One popular method for handling skewed outcome data is to logarithmically transform each observation before conducting the analysis with the resulting values.

D) It is likely that the income distribution curve you plot on a graph will be positively skewed to the right. If the majority of people earn normal earnings and a smaller proportion earn high incomes, then this would happen.

Therefore this is what skewed distribution is and the above mentioned ways are how one deals with skewed data in research.
