Find the slope of this graph.

Jerry pays $279.40 this year in property taxes.

To calculate Jerry's property taxes for the year, we need to first decide how many of his month-to-month maintenance fee is going toward property taxes.

The problem states that 20% of the price is for Jerry's assets taxes, which means we will calculate the amount of his belongings taxes with the aid of finding 20% of his monthly charge.

To do this, we multiply the price through 0.20 such as this:

20% of $1,397 = 0.20 x $1,397 = $279.40

Therefore, Jerry pays $279.40 this year in property taxes.

if parents were choosing from a list of 100 names, they would have many more choices than if they were choosing from a list of 50 names.

A probability is a tally of the chances or likelihood that a given event will occur. Probabilities can be expressed as proportions with a range of 0 to 1 or as percentages with a range of 0% to 100%.

If a newborn child may have either one, two, or three names, and parents are choosing from a list of 50 names, the number of choices for each number of names would be as follows:

1 name: 50 choices

2 names: 50 x 50 = 2500 choices

3 names: 50 x 50 x 50 = 125,000 choices

If parents were to choose from a list of 100 names, the number of choices would be:

1 name: 100 choices

2 names: 100 x 100 = 10,000 choices

3 names: 100 x 100 x 100 = 1,000,000 choices

Answer:

36 Cups

Step-by-step explanation:

You need to find how much punch Leon has. First, find how much grape juice he adds.

Leon adds 2 bottles of grape juice. Each bottle has 64 fluid ounces of juice.

2×64=128

Leon adds 128 fluid ounces of grape juice, but the problem asks about cups. So, find how many cups are equal to 128 fluid ounces. There are 8 ounces in a cup, so divide by 8.

128÷8=16

Leon adds 16 cups of grape juice.

Now, add to find how much punch Leon has in all. He uses 20 cups of ginger ale and 16 cups of grape juice.

20+16=36

Victor has 36 cups of punch in all.

The required cups of punch Leon will have is 36.

He pours 20 cups of ginger ale into his punch bowl. Then, he adds two 64-fluid-ounce bottles of grape juice.
To determine how many cups of punch Leon has.

In calculation, it deals with the numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
In the punch, there is  20 cups of ginger ale
he adds two 64-fluid-ounce bottles of grape juice,
= 64 * 2 = 128
= 128
Now, in 1 cup = 8 ounces. So,
number of cups in 128 ounces,

= 128 / 8 = 16
Now , total cups = 16 + 20 = 36

Thus, the required cups of punch Leon will have is 36.

Based on Chebyshev's Theorem, we can conclude that the lower bound for the number of bags in a sample of 225 that weigh between 335 and 371 gm is 200 bags.

Chebyshev's Theorem states that for any given number k greater than 1, at least (1 - 1/k²) of the data values in a dataset will fall within k standard deviations of the mean.

In this case, we have a sample size of 225 bags and a mean weight of 353 gm with a standard deviation of 6 gm.

To find a lower bound for the number of bags that weigh between 335 and 371 gm, we need to calculate the range within k standard deviations of the mean.

First, let's find the number of standard deviations for the given range:

Lower range: (335 - 353) / 6 = -3

Upper range: (371 - 353) / 6 = 3

Since we want to find the lower bound, we consider the lower range and use its absolute value: |-3| = 3.

Now, we can use Chebyshev's Theorem to find the lower bound:

(1 - 1/k²) ≤ (1 - 1/3²) = 1 - 1/9 = 8/9

This means that at least 8/9 of the bags will fall within 3 standard deviations of the mean.

To find the lower bound for the number of bags, we multiply this probability by the sample size:

Lower bound = (8/9) * 225 = 200

Therefore, based on Chebyshev's Theorem, we can conclude that the lower bound for the number of bags in a sample of 225 that weigh between 335 and 371 gm is 200 bags.

Step-by-step explanation:

Think of absolute value as a distance. For example, |5| can be written as |5 - 0| = 5 since the distance between 5 and zero on the number line is 5. Also, |-5| which is the same as |-5 - 0| is also 5 since the distance between -5 and zero on the number line is 5.

Since you want an absolute value equation with solutions 8 and 18, think of which number is the same distance from both 8 and 18 on the number line? Find the average of 8 and 18, (8 + 18)/2 = 13. 13 is the same distance from both 8 and 18. 13 is 5 units away from both 8 and 18. Now you need an equation that is looking for the numbers x which are 5 units distance from 13.

Therefore,

Hence, the answer is

The correct answer is option D: 4.8 inches. To find the measure of each side of a regular pentagon given its perimeter, we can divide the perimeter by the number of sides.

In this case, the perimeter of the regular pentagon is given as 24 inches, and a regular pentagon has 5 sides.

So, to find the measure of each side, we divide the perimeter (24 inches) by the number of sides (5).

Measure of each side = Perimeter / Number of sides

Measure of each side = 24 inches / 5 = 4.8 inches.

Therefore, the measure of each side of the regular pentagon is 4.8 inches.

Hence, the correct answer is option D: 4.8 inches.

A regular pentagon is a polygon with five equal sides and five equal angles. It has rotational symmetry of order 5, meaning that it looks the same after rotating 72 degrees around its center multiple times. Each side of the pentagon is congruent to the others, resulting in a uniform distribution of length.

In the given problem, the fact that the regular pentagon has a perimeter of 24 inches tells us that the total distance around all five sides is 24 inches. Dividing this total distance by the number of sides, which is 5, gives us the measure of each side. Therefore, each side of the regular pentagon measures 4.8 inches.

The main answer to your question is: OA. Carla pays more per magazine. Comparing the costs per magazine, we can see that Carla pays $2.46 per magazine, while Brandon pays $2.83 per magazine. Since $2.46 is more than $2.83, Carla pays more per magazine.

1. First, we need to find out how much Carla pays per magazine. To do this, we can use the information given that Carla pays $12.30 for 5 magazines and $24.60 for 10 magazines.

2. To find the cost per magazine for Carla, we can divide the total cost by the number of magazines. For 5 magazines: $12.30 / 5 = $2.46 per magazine. For 10 magazines: $24.60 / 10 = $2.46 per magazine. This shows that Carla pays $2.46 per magazine in both cases.
3. We know that Brandon's magazine cost can be represented by the equation y = $2.83x, where x is the number of magazines and y is the total cost. To find the cost per magazine for Brandon, we can simply look at the coefficient of x, which is $2.83. This means that Brandon pays $2.83 per magazine.
4. Comparing the costs per magazine, we can see that Carla pays $2.46 per magazine, while Brandon pays $2.83 per magazine. Since $2.46 is more than $2.83, Carla pays more per magazine.

(a) In a poker hand consisting of 5 cards, the probability of holding 3 face cards is to be calculated. Since a deck of cards contains 52 cards, there are only 12 face cards, which means that the total number of ways of getting 3 face cards from 12 is;   12C3.

The remaining two cards may be any of the 40 non-face cards, so there are 40C2 ways of choosing those two cards. Hence the total number of ways of obtaining three face cards and two non-face cards is; 12C3 × 40C2. Hence the probability of getting three face cards and two non-face cards is; 12C3 × 40C2 / 52C5 = 0.0043. Hence the answer is 0.0043. Therefore the probability of holding three face cards in a poker hand consisting of 5 cards is 0.0043. (Rounded to four decimal places as needed).

Answer:the best predicted value of ý when the twin born first has an IQ of 109 is 107.50

Step-by-step explanation:

Given the regression equation:

ŷ = -2.59 + 1.01x

We need to predict the value of ý when x (IQ score of the twin born first) is 109.

So we substitute x = 109 into the regression equation:

ŷ = -2.59 + 1.01(109)

ŷ = -2.59 + 110.09

ŷ = 107.50

Therefore, the best predicted value of ý when the twin born first has an IQ of 109 is 107.50.

The probability that neither of the two individuals has some college or a college degree is (1 - P(college))^2.

To calculate the probability that at least one of the two individuals chosen at random from the population will have some college or a college degree, we need to consider the complement of the event, which is the probability that none of the individuals have a college degree.

Let's assume that the population size is N, and the number of individuals with a college degree is C. The probability that an individual does not have a college degree is (N - C) / N.

When choosing the first individual, the probability that they do not have a college degree is (N - C) / N.

When choosing the second individual, the probability that they do not have a college degree is also (N - C) / N.

Since these events are independent, we can multiply the probabilities together:

P(no college degree for either individual) = (N - C) / N * (N - C) / N = (N - C)² / N².

Now, to find the probability that at least one of the individuals has a college degree, we subtract the probability of none of them having a college degree from 1:

P(at least one with a college degree) = 1 - P(no college degree for either individual) = 1 - (N - C)² / N².
