Answer:

(x+5)/(2x+3)

Step-by-step explanation:

So we know the top part is difference of two squares. So thats (x+5)(x-5)

The bottom part

Firstly you do 2 times -15= -30

Now we need to find two numbers with a difference of 7 but multiply to give 30.

30

1 x 30

2 x 15

3 x 10

5 x 6

From here we can see 3-10=-7 and multiply to make -30

So we do 2x²-10x+3x-15

simplify this in two different parts: 2x²-10x and 3x-15

2x(x-5) and 3(x-5)

Therefore we get (2x+3)(x-5)

(x+5)(x-5)/(2x+3)(x-5)

x-5 is common so they cancel each other out leaving you with

(x+5)/(2x+3)

I hoped this helped :)

The analyst could use the geom_jitter() function to make the points easier to find.

It is difficult for the analyst to distinguish the individual points on the plot because they overlap.

In this question we have been given a data analyst creates a scatterplot with a lot of data points. It is difficult for the analyst to distinguish the individual points on the plot because they overlap.

We need to find a function that could the analyst use to make the points easier to find.

We know that overplotting is caused due to discreteness in smaller datasets.

A function geom_jitter() adds a small random variation to the location of each point, which is a useful way of handling overplotting.

Whereas the function geom_point() adds a layer of points to given plot, which creates a scatterplot.

Therefore, geom_jitter() make the points easier to find.

Therefore, the correct option is D.

The ratio of the number of tulips to the number of roses in Julia's garden is 5:4.Let's represent the number of roses as 'r' and the number of tulips as 't'.

According to the given information, one half of the number of roses is equal to two fifths of the number of tulips. Mathematically, this can be expressed as:

(1/2) * r = (2/5) * t

To find the ratio of the number of tulips to the number of roses, we divide both sides of the equation by 'r':

(1/2) = (2/5) * t / r

Now, we can simplify the equation:

(1/2) = (2/5) * (t/r)

To eliminate the fraction, we can multiply both sides of the equation by 2:

2 * (1/2) = 2 * (2/5) * (t/r)

1 = (4/5) * (t/r)

Finally, to isolate the ratio of tulips to roses, we divide both sides of the equation by (4/5):

1 / (4/5) = (4/5) * (t/r) / (4/5)

5/4 = (t/r)

Therefore, the ratio of the number of tulips to the number of roses in Julia's garden is 5:4.

There are various factors that can distort the relationship between the independent and dependent variables. Nonetheless, the factor that most likely distorts the relationship between the two is the presence of a confounding variable.

What is a confounding variable

A confounding variable is an extraneous variable in a statistical model that affects the outcome of the dependent variable, providing an alternative explanation for the relationship between the dependent and independent variables. Confounding variables may generate false correlation results that lead to incorrect conclusions. Confounding variables can be controlled in a study through the experimental design to avoid invalid results. Thus, if you want to get a precise relationship between the independent and dependent variables, you need to ensure that all confounding variables are controlled.An example of confounding variables

A group of researchers is investigating the relationship between stress and depression. In their study, they discovered a positive correlation between stress and depression. They concluded that stress is the cause of depression. However, they failed to consider other confounding variables, such as lifestyle habits, genetics, etc., which might cause depression. Therefore, the conclusion they made is incorrect as it may be due to a confounding variable. It is essential to control all possible confounding variables in a research study to get precise results.Conclusively, confounding variables are the most likely factors that can distort the relationship between the independent and dependent variables.

Answer: Since her art and music sections each only had half the number of sheets of paper as a core subject, together the two sections had the same amount of paper as a core subject. Therefore, it is almost like her notebook had five core subjects, rather than four core subjects and two electives. If she divided the 200 sheets equally among the five core subjects, there would be 200 ÷ 5 = 40 sheets in each section. Now we can see that art would actually have half of this amount, or 20 sheets of paper.

The statement "The particular integral for 401 + 3y = 2e^(3t) using the Method of Undetermined Coefficients is πCe^(3t)dt" is False.

The Method of Undetermined Coefficients is a technique used to find a particular solution to a non-homogeneous linear differential equation. In this case, we are given the equation 401 + 3y = 2\(e^(3t)\). To apply the Method of Undetermined Coefficients, we assume a particular solution of the form y_p = A\(e^(3t),\) where A is a constant to be determined.

We differentiate y_p with respect to t to find its first derivative: y_p' = 3A\(e^(3t).\) Plugging this into the original equation, we have 401 + 3(3A\(e^(3t)) =\) 2\(e^(3t).\) Simplifying, we get 401 + 9A\(e^(3t) =\) 2\(e^(3t)\).

To equate the coefficients of the exponential term, we find that 9A = 2. Solving for A, we get A = 2/9. Therefore, the particular solution is y_p = (2/9)\(e^(3t)\), not πC\(e^(3t)dt\) as stated in the given statement.

In conclusion, the statement "The particular integral for 401 + 3y = \(2e^(3t)\)using the Method of Undetermined Coefficients is πCe^(3t)dt" is False. The correct particular integral obtained using the Method of Undetermined Coefficients is y_p = (2/9)e^(3t).\(e^(3t).\)

Miriam can serve 72 four-ounce servings of punch, which corresponds to option D.

To find the number of 4-ounce servings of punch Miriam can serve, we need to convert the gallons to ounces and then divide by 4.

First, we convert 2 1/4 gallons to ounces:

1 gallon = 128 ounces

1/4 gallon = 1/4 * 128 = 32 ounces

So, 2 1/4 gallons is equal to 2 * 128 + 32 = 256 + 32 = 288 ounces.

Next, we divide the total ounces by 4 to find the number of 4-ounce servings:

288 ounces / 4 ounces = 72 servings.

Using the t-distribution, we have that the 95% confidence interval for the true mean number of pushups that can be done is (9, 21).

For this problem, we have the standard deviation for the sample, thus, the t-distribution is used.

First, we find the number of degrees of freedom, which is the one less than the sample size, thus df = 9.

Then, looking at the t-table or using a calculator, we find the critical value for a 95% confidence interval, with 9 df, thus t = 2.2622.

The margin of error is of:

\(M = t\frac{s}{n}\)

Then:

\(M = 2.2622\frac{9}{\sqrt{10}} = 6\)

The confidence interval is:

\(\overline{x} \pm M\)

Then

\(\overline{x} - M = 15 - 6 = 9\)

\(\overline{x} + M = 15 + 6 = 21\)

The confidence interval is (9, 21).

Lana would pick a non-striped marble about 294 times.

The probability of picking a marble that is not striped is 100% - 8% = 92% = 0.92. This means that for each pick, the probability of getting a non-striped marble is 0.92.

If Lana picks a marble and replaces it 320 times, the number of times she would pick a non-striped marble can be predicted by multiplying the probability of getting a non-striped marble by the number of picks.

So, the number of times she would pick a non-striped marble is:

0.92 x 320 = 294.4

The points jada score is 159.25.

Given that james scored 182 points while playing a video game and he scored 7 times as many points as jada scored.

Let x be the points scored by james and y be the points scored by jada.

The total points scored by james and jada is 182 points.

x+y=182    .....(1)

James scored 7 times many points as jada scored.

y=7x         .....(2)

So, there are two equations and two unkowns.

Firstly, we will substitute equation (2) in equation (1), we get

x+7x=182

8x=182

Divide both sides by 8, we get

8x/8=182/8

x=22.75

Further, we will substitute the value of x in equation (2), we get

y=7×22.75

y=159.25

Hence, the jada score 159.25 when james scored 182 points while playing a video game and ahe scored 7 times as many points as jada scored.

The number of possible combinations of three coins from the bag of 16 coins with different dates can be calculated using the formula for combinations, which is nCr = n! / r!(n-r)!, where n is the total number of objects, r is the number of objects to be chosen, and ! denotes factorial (the product of all positive integers up to the given number).

In this case, we have n = 16 (the total number of coins in the bag) and r = 3 (the number of coins to be chosen for each combination). Using the formula for combinations, we can calculate the number of possible combinations as follows:

nCr = 16! / 3!(16-3)!
nCr = (16 x 15 x 14) / (3 x 2 x 1)
nCr = 560

Therefore, 560 possible combinations of three coins can be chosen from the bag of 16 coins with different dates. These combinations could represent different historical events, significant dates, or other symbolic meanings depending on the dates inscribed on the coins. The calculation of combinations is an important concept in combinatorics and probability theory, and it has many real-world applications in fields such as statistics, economics, and computer science.

The distance between two points (-3, -3), and (-8, 6) is,

⇒ d = 10.3 units

We have to given that,

Two points are (-3, -3), and (-8, 6).

Since, We know that,

The distance between two points (x₁ , y₁) and (x₂, y₂) is,

⇒ d = √ (x₂ - x₁)² + (y₂ - y₁)²

Hence, We get;

The distance between two points (-3, -3), and (-8, 6) is,

⇒ d = √ (x₂ - x₁)² + (y₂ - y₁)²

⇒ d = √(- 8 + 3)² + (6 + 3)²
