To find the mean (average), we first need to add up all the test scores (14 + 19 + 19 + 20 + 16 + 18 + 15 + 17 + 12 = 150). Then, we need to divide that number (150) by the number of numbers in the data set (9 in this case). So the mean of these test scores is about 16.6666666667.

Answer:

x= -2

Step-by-step explanation:

Rational Function can be expressed as:

$\displaystyle \large{y = \frac{a}{p(x - b)} + q}$

Where b is our horizontal shift and q is our vertical shift.

For asymptotes, there are two types which are vertical and horizontal.

Vertical Asymtote is the value of -b itself or x = -b.

Therefore, from the functio:

$\displaystyle \large{y = \frac{10}{x + 2} }$

Our vertical asymtote is x = -2

Answer:

4/3π - √3

Step-by-step explanation:

Pie piece of circle is area of circle x portion of circle

πr²*x/360 = π(2)²*120/360 = 4/3π

Then you must subract the non-right triangle area

1/2ab sin C = 1/2(2)(2) sin 120 = 2 * √3/2 = √3

4/3π - √3
