The Mean would increase to 82.17 or a total increase of .17
You have 99 students and the avg is 82, therefore we can multiply 99*82 to get our total points
99*82=8118
We add a single score of 99 to our total points 8118+99= 8217
Then we add the student to the total number of students bringing it to 100 and divide our new total by the our new number of students.
8217/100 = 82.17
Answer:
Company B
Step-by-step explanation:
28.50 plus 18= 46.50
16.50 plus 20= 36.50
Answer:
+ 3x +9x +27 = 0
x(x+3)+9(x+3)=0
(x+3)(x+9)=0
x=-3, x=-9
Step-by-step explanation:
a=1 b=12 c=27
sum=12
factor=27x 1
3x9
also 3+9=12
Answer:
Step-by-step explanation:
<h3>Given </h3>
- Point (5, -7) and midpoint (15, 1)
<h3>To find</h3>
<h3>Solution</h3>
<u>Midpoint formula:</u>
- x = (x1 + x2)/2,
- y = (y1 + y2)/2
<u>Substituting values:</u>
- 15 = (5 + x2)/2 ⇒ 5 + x2 = 30 ⇒ x2 = 30 -5 ⇒ x2 = 25
- 1 = (-7 + y2)/2 ⇒ -7 + y2 = 2 ⇒ y2 = 2 - (-7) ⇒ y2 = 9
<u>Missing endpoint is:</u>
Plug in what ever value is the function of g for x and solve:
g(3) = |3-3| = |0| = 0
g(-3) = |(-3)-3| = |(-6)| = 6
Hope this helps :)
