The equivalent square root for \(\sqrt[\sf 2]{\sf 81\text{x}}\) is \(\sf 9\sqrt{\text{x}}\).

In mathematics, a square root of a number x is a number y such that; in other words, a number y whose square (the result of multiplying the number by itself, or) is x.

Given the the square root, we need to find the equivalent square root for \(\sqrt[\sf 2]{\sf81\text{x}}\).

So,

Rewrite \(\sqrt[\sf 2]{\sf81\text{x}}\) as \(\sqrt{\sf9(\text{x})}\).

Then, pull terms out from under the radical, assuming positive real numbers.

\(\sqrt{\sf9(\text{x})}=\bold{9\sqrt{x}}\)

Therefore, The equivalent square root for \(\sqrt[\sf 2]{\sf 81\text{x}}\) is \(\sf 9\sqrt{\text{x}}\).

When a range of values is used to estimate a population parameter, it is called an interval estimate. The correct answer is option D.

An interval estimation is the evaluation of a parameter of a population by computing an interval, or range of values, within which the parameter is most likely to be located. An interval estimate gives you a range of values where the parameter is expected to lie. In other words, an interval estimate is a range in which the population parameter probably falls for a given level of confidence. We have to establish a level of confidence because we can never be 100 percent sure that the population mean falls within our confidence interval. A confidence interval is the most common type of interval estimate.

The area of a rectangle is its length multiplied by its width. Substitute the known values into this equation and solve for the length, l:

8342 = 86l

l = 97

Answer: $4,914

Step-by-step explanation:

To calculate the final balance in Brandon's account, we need to use the formula for compound interest: A = P(1 + r/n)^(nt)

where A is the final balance, P is the initial investment, r is the interest rate, n is the number of times the interest is compounded per year, and t is the time in years.

In this case, we have:

P = $11,000

r = 1% = 0.01

n = 4 (because the interest is compounded quarterly)

t = 20

so, A = $11,000(1 + 0.01/4)^(4*20) = $11,000(1.0025)^80 = $22,817.20

To calculate the final balance in Robert's account, we need to use the same formula, but with different values for r, n, and t.

In this case, we have:

P = $11,000

r = 13/100 = 0.13

n = 12 (because the interest is compounded monthly)

t = 20

so, A = $11,000(1 + 0.13/12)^(12*20) = $11,000(1.01083333)^240 = $27,731.34

To find the difference in the final balances, we subtract the final balance in Brandon's account from the final balance in Robert's account:

$27,731.34 - $22,817.20 = $4,914.14

To the nearest dollar, the difference is $4,914.

I think the last graph is your answer

The graph of the linear inequality x - 2y > -12 is the region above the line

y = 1/2x + 6, shaded to the right of the line.

Option D is the correct answer.

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal = ≤

Greater than and equal = ≥

We have,

The linear inequality x - 2y > -12 represents all the points on the coordinate plane that satisfy the inequality.

To graph this inequality, we can start by graphing the line x - 2y = -12, which is the boundary line of the inequality.

To graph this line, we can rearrange it into the slope-intercept form:

x - 2y = -12

-2y = -x - 12

y = 1/2x + 6

Now we can graph the line y = 1/2x + 6 by plotting the y-intercept at (0,6) and using the slope of 1/2 to find another point.

We can do this by going up 1 unit and right 2 units from the y-intercept to get the point (2,7) and so on.

Therefore,

The graph of the linear inequality x - 2y > -12 is the region above the line

y = 1/2x + 6, shaded to the right of the line.

The value of f(x) + h(x) when f(x) = 2x - 1 and h(x) = x² + 1 is x² + 2x.

Addition of linear functions:
Addition of two individual functions, a(x) and b(x); linearly, results in the formation of the functional addition, c(x) of the two functions, such as:
c(x) = a(x) + b(x) = (a+b)(x) – (i)
The addition of the functions strictly restricts to simple linear addition without any pre-defined constraints.

Given, f(x) = 2x - 1, g(x) = 3x and h(x) = x² + 1
Using the available formula in (i), we get
f(x) + h(x) = (f + h)(x) = (2x - 1) + (x² + 1) = x² + 2x = x(x + 2), which is a quadratic equation.

Thus, even if the expected value of option A is higher than the expected value of option B, EUT cannot account for the preference.

Expected Utility Theory (EUT) asserts that a decision-maker's utility function can be used to predict their preferences between uncertain options.

If a decision-maker has an ordered preference ranking of lotteries, according to EUT, these rankings would correspond to their expected utility rankings.

Nevertheless, some examples demonstrate that EUT may fail to predict preferences. Let's denote a lottery as

(X₁, P₁; X2, P2; ; Xm, Pm),

where Xi and Pi indicate the reward magnitude and probability of each potential outcome.

A decision-maker prefers B ($5000, 1.00) to

A = ($0, 0.01; $25000, 0.04; $5000, 0.95) and prefers

C = ($25000, 0.04; $0, 0.96) to

D = ($5000, 0.05; $0, 0.95).

However, EUT cannot account for these preferences.

The utility of the three alternatives is calculated as follows:

U(B) = $5000

U(C) = 0.04 × $25,000 + 0.96 × $0 = $1,000

U(D) = 0.05 × $5000 + 0.95 × $0 = $250

However, the expected utilities of A and B cannot be compared.

These preferences might instead be clarified using theories like Rank-Dependent Expected Utility Theory.

The difficulty of the test is consistent and unchanging, making it so that the chance of failing is solely determined by the individual's performance on the test. Factors such as knowledge of the subject and the ability to focus can play a role in a person's success, but the actual chance of failing is not affected by how many times the test is taken. This means that those who fail the test will have to work harder and prepare better in order to pass it on the next attempt.
