Answer:
<u>The mean of Jorge's scores is 119 (rounding to the next whole).</u>
Step-by-step explanation:
- 1st score = 131
- 2nd score = 110
- 3rd score = 128
- 4th score = 105
- 5th score = 120
Mean of Jorge's scores = (131 + 110 + 128 + 105+ 120)/5
Mean of Jorge's scores = 594/5
Mean of Jorge's scores = 118.8
<u>Mean of Jorge's scores = 119 (rounding to the next whole).</u>
When both the x and the y in coordinates are positive and not equal to zero, the points are in Quadrant I. So, the correct answers are (1,1), (7,3), and (1,10). Hope this helps!
The Correct choice is ~ A
Because the two lines are parallel, the given angles forms Corresponding angle pair. and therefore they have equal measures.
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
