If Mike scores two standard deviations above the mean then the Mike's percentile-score is 97.72 ≈ 98 percentile.

The percentile score corresponding to a raw test score, is the probability of the test score of a randomly chosen student to be less than or equal to the given test score.  To calculate this probability we find the value of the cumulative distribution function of the test score random variable at the given test score.

To calculate the percentile score of the given raw test score we have to find the value of the cumulative distribution function for the test score random variable at the given raw test score. if this random variable is X, then the linearly scaled random variable [tex]Z=\frac{X-\mu}{\sigma}[/tex], has standard normal-distribution. here [tex]\mu\textrm{ and }\sigma[/tex] are the mean and the standard deviation of the test score r.v respc. Also [tex]\textrm{P}(X\leq x_0) = \textrm{P}(Z\leq z_0),\textrm{ where }z_0=\frac{x_0-\mu}{\sigma}[/tex].  So instead of finding [tex]\textrm{P}(X\leq x_0)\textrm{, we can find } \textrm{P}(Z\leq z_0)[/tex] instead. [tex]z_0[/tex] is called the z-score corresponding to the [tex]x_0[/tex]. We can find [tex]\textrm{P}(Z < z_0)[/tex], using the table for the standard normal distribution.

For our question, we want to find [tex]\textrm{P}(X\leq \mu + 2\sigma)[/tex]. which is equal to [tex]\textrm{P}(Z\leq \frac{\mu+2\sigma - \mu}{\sigma}) = \textrm{P}(Z\leq 2).[/tex] So the z-score = 2. From the table for the standard normal distribution we get [tex]\textrm{P}(Z\leq 2) = .9772[/tex]. So our percentile score is .9772 or 97.72% [tex]\sim[/tex] 98%.

Answer:

$705.71

Step-by-step explanation:

Let's assume the regular price of the sofa is "x".

According to the problem statement, the sale price is 65% off the regular price, which means the sale price is equal to 35% of the regular price.

We can write this relationship as:

0.35x = $247

To find the value of "x", we need to solve for "x" in the above equation.

Dividing both sides by 0.35, we get:

x = $247 ÷ 0.35

x = $705.71

Therefore, the regular price of the sofa is $705.71.

Union will need to choose a random sample of at least 65 wages to be 90% confident that its estimate of the mean hourly wage of foodservice workers is within $0.45 of the true population mean.

To calculate the minimum sample size needed for the union to be 90% confident within $0.45 of the true population mean, we can use the formula which states n = (Z^2 * σ^2) / E^2

Z = 90% = 1.645

σ = $2.20

E = $0.45

Substituting the values, we get:

n = (1.645^2 * 2.20^2) / 0.45^2

n = 13.097161 / 0.2025

n = 64.6773382716

n = 64.678

Rachel $8500 invested at 4% and $8800 invested at 2% interest rate.

Investment is the act of allocating money or resources with the expectation of generating income or profit in the future.

Let x be the amount invested in the second account (with a 4% interest rate).

Then, since Rachel invested $300 more in the first account, the amount invested in the first account (with a 2% interest rate) is (x + 300)

We know that the total interest income Rachel earned was $516. We can set up an equation using the interest formula: (2% means 0.02 and 4% means 0.04)

⇒ 0.02(x + 300) + 0.04x = 516
⇒ 0.02x + 6 + 0.04x = 516
⇒ 0.06x + 6 = 516
⇒ 0.06x = 510
⇒ x = 8500

So, Rachel invested $8500 in the second account (with a 4% interest rate)

and (x + 300) = (8500 + 300) = $8800 in the first account (with a 2% interest rate).

Therefore, Rachel $8500 invested at 4% and $8800 invested at 2%.

The measure of the angle ∠6 is 102 degrees for the given parallel lines.

Two angles are said to be supplementary if their sums equal 180 degrees. In other words, if angles A and B are complementary, then the sum of the two angles is 180 degrees. Four angles are created when two lines intersect; if two of these angles are supplementary, the other two are likewise supplementary.

Since 70 + 110 = 180 degrees, 70 degrees and 110 degrees serve as an illustration of a pair of supplementary angles. Another illustration is a pair of vertical angles, which are always supplementary and are generated by the intersection of two lines.

The measure of angle of a straight line is given as 180 degrees.

Thus,

∠6 + 78 = 180

∠6 = 180 - 78

∠6 = 102

Hence, the measure of the angle ∠6 is 102 degrees for the given parallel lines.

Sarah's daily outgoings on wages are £892.50.

What is wages?

Wages refer to the payment made to an employee in exchange for their labor or services provided to an employer. It is usually paid on an hourly, daily, weekly or monthly basis, and the amount of wages earned is determined by the hours worked, rate of pay, and any applicable deductions or taxes. Wages can be paid for various types of work, such as manual labor, skilled trades, clerical work, or professional services. It is an essential component of an employee's compensation package and is regulated by labor laws to ensure that employees are fairly compensated for their work.

Each employee works for 8.5 hours a day (17:00 - 08:30 = 8.5). So, the total number of hours worked by 12 employees in a day is 12 employees × 8.5 hours/employee = 102 total hours

Sarah pays each employee £8.75 per hour, so her total daily outgoings on wages can be calculated as,

102 total hours × £8.75 per hour/employee = £892.50

Therefore, Sarah's daily outgoings on wages are £892.50.

Answer:

x = 6.111... and y = 1.

Step-by-step explanation:

To use Cramer's Rule, we first write the system of equations in matrix form, where the coefficients of x and y are placed in a matrix, and the constant terms are placed in a separate matrix. We then calculate the determinant of the coefficient matrix, which is the number that is obtained by multiplying the diagonal elements and subtracting the product of the off-diagonal elements.

Next, we replace the first column of the coefficient matrix with the constant terms and calculate the determinant of the resulting matrix. We do the same thing for the second column of the coefficient matrix. We then use Cramer's Rule to solve for x and y, which involves dividing the determinant of the matrix obtained by replacing the column of x coefficients with the constant terms by the determinant of the coefficient matrix to get the value of x. We do the same thing to find the value of y by dividing the determinant of the matrix obtained by replacing the column of y coefficients with the constant terms by the determinant of the coefficient matrix.

In the case of the given system of equations, the determinant of the coefficient matrix is 18. We then calculate the determinants of the matrices formed by replacing the first column of the coefficient matrix with the constant terms and the second column of the coefficient matrix with the constant terms. Using these determinants, we apply Cramer's Rule to find the values of x and y, which are x = 6.111... and y = 1.

a. First to find the area under the graph, we find the values of a and b. From the graph, a = 1 and b = 3

b. To find f(x), we note that f(x) is a straight line. So, using the equation of a

in slope form, we have that

(y - y')/(x - x') = (y" - y')/(x" - x') where

So, substituting the values of the variables into the equation, we have that

(y - y')/(x - x') = (y" - y')/(x" - x')

(y - 5)/(x - 0) = (4 - 5)/(4 - 0)

(y - 5)/x = -1/4

y - 5 = -x/4

y = -x/4 + 5

So, f(x) = -x/4 + 5

c. To find the area under the curve, we notice that ∫f(x)dx = area

So, ∫f(x)dx = ∫₁³(-x/4 + 5)dx

The volume of the rectangular prism is 144 in³ with the area of the base is 24 square inches and the height is 6 inches.

Volume is a measure of the amount of physical space occupied by an object or a fluid.

This is because the volume of a rectangular prism can be calculated by the formula V = A x h, where V is the volume, A is the area of the base, and h is the height. In this problem, the area of the base is 24 square inches and the height is 6 inches.

Therefore, the volume of the rectangular prism can be calculated as follows:

V = 24 in² x 6 in

= 144 in³

It is important to note that the formula for calculating the volume of a rectangular prism can be used for any rectangular prism, regardless of the size of the area of the base and the height. The formula remains the same and the only thing that changes is the numbers that are used to calculate the volume.
