You have three options, all of them work.
sin(angle) = opposite/hypotenuse
cos(angle) = adjacent/hypotenuse
tan(angle) = opposite/adjacent

You are already given the length of the lines, so all you can is to take the inverse of whatever you choose to get the angle.

$sin^{-1}$ (5/13) = 22.62

$cos^{-1}$ (12/13) = 22.62

$tan^{-1}$ (5/12) = 22.62

Find the mean, median, mode, and range of these numbers 75,95,90,95,60,95,75,95,90 Plzzzzzz

Shtirlitz [24]

Answer:

Mean: 85 5/9

Median: 90

Mode: 95

Step-by-step explanation:

~ Part I ~

1. To find the mean, let us take the average of the numbers through the addition of these values divided by the number of numbers:

75 + 95 + 90 + 95 + 60 + 95 + 75 + 95 + 90/9 = 770/9 = 85 5/9 (85.55.....)

~ Part 2 ~

1. Now let us arrange these numbers from least to greatest:

75 , 95 , 90 , 95 , 60 , 95 , 75 , 95 , 90 ⇒ 60,75 , 75 , 90 , 90 , 95, 95, 95,95

3. The median of this set would now be the middle number, which, (in this case) is ⇒ 90

~ Part 3 ~

1. The mode is known to be the number repeated most often, and from the previous question we see the numbers arranged in a benficial manner. Now we can straight away see that the number repeated the most is ⇒ 95

Suppose you are paid an annual salary, plus a bonus of 20% on annual sales over $500,000. Consider the two functions f(x) = x −

melisa1 [442]

Answer:

C. $g\,\circ \, f (x) =g(f(x))$

Step-by-step explanation:

Let be $f(x) = x-500000$ the excedent on annual sales and $g(x) = 0.2\cdot x$ the bonus factor, to determine the bonus amount a composition of $f(x)$ is $g(x)$ must be done. That is:

$g\,\circ \, f (x) =g(f(x))$

Hence, the right answer is C.
