Answer:

A. 12

Step-by-step explanation:

TU and CV are two chords of the circle that intersects at point w.

Thus,

$x*3 = 9*4$ (two intersecting chords theorem)

Solve for x

$3x = 36$

Divide both sides by 3

$\frac{3x}{3} = \frac{36}{3}$

$x = 12$

How do you calculate gross pay net pay and employee benefits

Sonja [21]

Gross pay is the amount of money your employees receive before any taxes and deductions are taken out. For example, when you tell an employee, “I'll pay you $50,000 a year,” it means you will pay them $50,000 in gross wages.

Hope this helps!!

A frequency table of grades has five classes (A, B, C, D,F) with frequencies of 4, 10, 17, 6, and respectively. Using percentage

fiasKO [112]

We have the frequencies for each of the grades. We can estimate the number of students graded by adding all those frequencies. Let's call N the total number of grades:

$\begin{gathered} N=4+10+17+6+2 \\ N=39 \end{gathered}$

We have then a total number of grades of 39.

The corresponding relative frequency for a grade is the ratio of the frequency to the total number of "samples", 39 in this case.

Then, for grade A, the relative frequency (RF) will be:

$RF_A=\frac{4}{39}\approx0.10256\approx10.26\text{ \%}$

This will be the fraction of the total grades that are A. Represented as a percentage will be 10.26%, rounded to two decimal places.

Now, to complete the table we do the same for the other frequencies:

For grade B:

$RF_B=\frac{10}{39}\approx0.2564\approx25.64\text{ \%}$

For grade C:

$RF_C=\frac{17}{39}\approx0.4359\approx43.59\text{ \%}$

For grade D:

$RF_D=\frac{6}{39}\approx0.1538\approx15.38\text{ \%}$

For grade F:

$RF_D=\frac{2}{39}\approx0.0513\approx5.13\text{ \%}$
