Let the angle of elevation be x, then
tan x = 1/12
x = arctan (1/12) = 4.8 degrees.
Answer:
The value of the 50th percentile is 33.2 hours.
Step-by-step explanation:
The median corresponds to the 50th percentile, then the value of the 50th percentile is 33.2 hours.
Answer: D: $5272.
Step-by-step explanation:
Considering that all of the information is given to you already, the only thing that you need to do is plugin 9 for n.
So the final equation will look like this: 
The answer comes out to $5272.46721451 but rounding that to the nearest dollar would be answer choice D: $5272.
Step-by-step explanation:
staff of 600 is 300 and the form of 1050 is 525
Answer:
f(g(x))=(x-2)^2 - 7
(x-2)(x-2) - 7
x^2-2x-2x+4-7
x^2-4x-3
g(f(x))=x^2-2-7
x^2-9
(x+3)(x-3)
Step-by-step explanation:
- to solve for f(x), replace x with the g(x).
- since we don't multiply a bracket with the negative or the positive signs to the
- exponent, you have to factor into two binomials.
- use the FOIL method to eliminate the brackets.
- add like-terms
- to find g(x), replace x with the f(x).
- add like-terms
- since there's difference of square, factor them into two binomials
