Answer/Step-by-step explanation:
✔️Find k:
Reference angle = 60°
Hypotenuse = k
Opposite = 9
Therefore, using trigonometric ratio, we have:

Multiply both sides by k

Divide both sides by sin(60)




Rationalize



✔️Find f:
Reference angle = 60°
Opposite = 9
Adjacent = f
Therefore, using trigonometric ratio, we have:

Multiply both sides by f

Divide both sides by tan(60)

Answer:
Given:
Null hypothesis: the average salary for new college graduates with a job is $50,556.
Alternative hypothesis: the graduates from a university earn more than that average.
Using the z-test:
=> Calculate the value of test statistic:
t = (mean of sample - mean of null hypothesis)/(std/sqrt(number of sample)
= (53200 - 50556)/(10200/sqrt(100))
= 2.592 > 1.645
=> Reject the null hypothesis, their graduates earn more than average
Hope this helps!

A line perpendicular to the y axis is horizontal line (parallel to the x axis).
Equation of this line is y = a.
The line passes through (3, -8) → x = 3 and y = -8.
Therefore your answer is y = -8.
Answer:
$39
Step-by-step explanation:
He has $115 total, and he spent it on shirts and pants
First, find how much money he spent
Shirts:
5 shirts at $11 each
5*11=55
$55
Pants:
$21
To find how much he has left, subtract what he spent from the total amount of money he had to begin with
total-shirts-pants
115-55-21=39
He has $39 left to buy more clothes
