Please answer this question.

Step-by-step explanation:

\(25(x - 910) = - 234 \\ 25x - 22750 = - 234 \\ 25x = 22516 \\ x = \frac{22516}{25} \\ x = 900 \frac{16}{25} \)

The value of x is \(900\frac{16}{25}\) for the equation 25(x−910)=−234.

Two or more expressions with an Equal sign is called as Equation.

The given equation is 25(x−910)=−234

Twenty five times of x minus nine hundred ten equal to minus two hundred thirty four.

25(x−910)=−234

We need to solve for x

Apply distributive property on left hand side

25x-22750=-234

Add 22750 on both sides

25x=-234+22750

25x=22516

Divide both sides by 25

x=22516/25

\(x=900\frac{16}{25}\)

Hence, the value of x is \(900\frac{16}{25}\) for the equation 25(x−910)=−234.

Renee reads the same fraction of a different book over the same period of time as Eliza. Renee's book has a total of 406 pages.

The number of pages Renee reads more than Eliza can be determined by finding the difference in the fractions they read.

To find the number of pages Renee reads more than Eliza, we need to know the fraction of the book they both read. Let's assume they read a fraction of "x" of their respective books.

Since Renee's book has 406 pages, the number of pages she reads is 406 * x.

To find the number of pages Eliza reads, we need to know the total number of pages in her book. Let's assume Eliza's book has "y" pages. Therefore, the number of pages Eliza reads is y * x.

The difference in the number of pages they read can be calculated as follows:

406 * x - y * x

Since they both read the same fraction of their respective books, x can be canceled out:

(x * (406 - y))

Therefore, the number of pages Renee reads more than Eliza is given by (x * (406 - y)). The specific value of the difference would depend on the fraction they both read and the total number of pages in Eliza's book, y.

To find the volume of the solid whose base is bounded by the circle x^2 + y^2 = 4, with squares as cross-sections perpendicular to the x-axis, we need to determine the correct expression for the radius.

The equation of the circle is x^2 + y^2 = 4, which can be rewritten as y^2 = 4 - x^2.

To find the radius of each square cross-section, we need to consider the distance between the x-axis and the upper and lower boundaries of the base circle.

The upper boundary of the base circle is given by y = sqrt(4 - x^2), and the lower boundary is given by y = -sqrt(4 - x^2).

The distance between the x-axis and the upper boundary is the radius of the square cross-section, so we can express it as r = sqrt(4 - x^2).

Therefore, the correct expression for the radius of each square cross-section is r = sqrt(4 - x^2).

To confirm, let's consider a specific value of x. For example, if we take x = 1, the equation gives:

r = sqrt(4 - 1^2) = sqrt(3).

This means that the radius of the square cross-section at x = 1 is sqrt(3), which matches the expected value.

Hence, the correct expression for the radius of each square cross-section perpendicular to the x-axis is r = sqrt(4 - x^2).

The area under the standard normal curve between z=â1.16 and z=â0.03 is 0.3663.

To find the area under the standard normal curve between z = -1.16 and z = -0.03, we will use the following steps:

1. Look up the z-values in the standard normal distribution table (or use a calculator or online tool that provides the corresponding probability values).
2. Subtract the probability value for z = -1.16 from the probability value for z = -0.03.
3. Round your answer to four decimal places.

Step 1: Look up the z-values in the standard normal distribution table.
- For z = -1.16, the corresponding probability value is 0.1230.
- For z = -0.03, the corresponding probability value is 0.4893.

Step 2: Subtract the probability values.
Area = P(-0.03) - P(-1.16) = 0.4893 - 0.1230

Step 3: Round the answer to four decimal places.
Area = 0.3663

So, the area under the standard normal curve between z = -1.16 and z = -0.03 is approximately 0.3663.

To determine how large a test statistic must be to reject the null hypothesis in favor of the alternative hypothesis, we need to first establish a hypothesis test. A hypothesis test is a statistical procedure that helps us determine if there is enough evidence to support a particular hypothesis.

In a hypothesis test, we start with a null hypothesis (H0) which is a statement that there is no significant difference between two groups or variables. The alternative hypothesis (Ha) is the statement that there is a significant difference between the two groups or variables.

Once we have established our null and alternative hypotheses, we need to conduct a statistical test to determine if there is enough evidence to reject the null hypothesis in favor of the alternative hypothesis. The test statistic is the numerical value that we obtain from our statistical test, which we compare to a critical value to determine if we can reject the null hypothesis.

The critical value is determined by the level of significance (α) we have chosen for our test, which is the probability of making a type I error (rejecting the null hypothesis when it is actually true). Typically, the level of significance is set at 0.05 or 0.01.

So, to answer the question, how large a test statistic must be to reject the null hypothesis in favor of the alternative hypothesis depends on the level of significance we have chosen, as well as the degrees of freedom and distribution of the test statistic. The critical value for a given level of significance and degrees of freedom can be found in statistical tables or calculated using software. If the test statistic is larger than the critical value, we can reject the null hypothesis in favor of the alternative hypothesis.

If two events are collectively exhaustive, then the probability that both occur at the same time is 1.00 (Option c)

Probability is a quantification of how likely an event is to occur. Typically, probabilities are defined as the chances that a specific outcome will occur out of a given selection of outcomes. A probability is expressed mostly in decimal form, taking values between 0 and 1. Probabilities cannot exceed this particular range of values.

Firstly, To clarify : You are confusing mutually exclusive and jointly collectively exhaustive.

The former describes condition which cannot both (or all) obtain. and so exclude one another.

i.e., "not - (both A and not - A)"

The latter describes conditions, one of which must obtain, and so exhaust the field of possibilities. i.e., "either A or not - A"

I presume you intend to refer to the latter.

Second, to answer your question: If two events - are jointly exhaustive, their probabilities must by definition sum to 1.

Based on the pattern of increasing numbers in the table, a reasonable value for the missing cell would be option c, 9.

Looking at the table, we can see that each number is increasing by approximately the same amount from left to right and from top to bottom. Specifically, each row and each column increases by a consistent value of 1.2. For example, the first row increases from 4.4 to 5.6 to 6.8, and the second row increases from 5.6 to 6.8 to 8.0.

Using this pattern, we can estimate the value of the missing cell by looking at the corresponding row and column. The missing cell is in the third row, so we can estimate it by adding 1.2 to the previous cell in the row, which is 7.2. This gives us an estimate of 8.4.

However, none of the answer choices include 8.4, so we need to consider which of the given options is closest to this estimate. Option c, 9, is the closest option, and it is also the option that makes the most sense given the pattern of increasing numbers in the table.

The best estimate of the elk population, to the nearest whole number, is 250.

To estimate the elk population, we can use the mark-recapture method. This method assumes that the ratio of marked individuals to the total population is equal to the ratio of marked individuals recaptured to the total number of individuals captured in the second sample.

Let's denote the total elk population as "P" and the number of marked elk in the first sample as "M1". We also know the number of marked elk recaptured in the second sample, which is "M2", and the total number of elk counted in the second sample, which is "N2".

According to the mark-recapture method, we can set up the following equation:

M1 / P = M2 / N2

Plugging in the given values, we have:

30 / P = 18 / 150

To solve for P, we can cross-multiply and then divide:

30 * 150 = 18 * P

4500 = 18P

Dividing both sides by 18:

P = 4500 / 18

P ≈ 250

Loan = 4,050

Interest rate = 6.5%

Time = 2 years

To get our Interest, we will use the simple interest formula which is "S.I. = PRT/100". Where P is 4050, r = 6.5%, T= 2 years.

This text describes a scenario where someone has taken out a loan of $4050. The loan has an interest rate of 6.5%, which means that the borrower will have to pay an additional 6.5% of the loan amount as interest. The loan is taken for a period of 2 years, which is the time frame during which the borrower has to repay the loan.

The question being asked is about the interest that will be accumulated on this loan. Interest accumulation refers to the increase in the amount of money that the borrower owes due to the interest that is being charged on the loan.

In this case, we need to calculate the total amount of interest that will be charged over the 2-year period, based on the loan amount and interest rate.

To calculate the interest accumulated on this loan, we can use the following formula:

Interest = Principal * Rate * Time

Where:

- Principal = the amount borrowed (in this case, $4050)

- Rate = the interest rate (in this case, 6.5% or 0.065 as a decimal)

- Time = the length of the loan in years (in this case, 2 years)

Plugging in the values, we get:

Interest = $4050 * 0.065 * 2

Interest = $527.25

So the interest accumulated on this loan is $527.25. This means that the borrower will have to pay back a total of $4577.25 ($4050 + $527.25) over the 2-year period.
