Answer:
x = 5
Step-by-step explanation:
Corresponding sides are proportional, so we can write the proportion ...
(x -2)/x = (x +1)/(x +5)
(x -2)(x +5) = x(x +1) . . . . . . . multiply by x(x+5)
x^2+3x -10 = x^2 +x . . . . . eliminate parentheses
2x = 10 . . . . . . . . . . . . . . subtract x^2+x-10
x = 5 . . . . . . . . . . . . . . divide by 2
Answer:
-The mean will decrease, and the median will stay the same.
Step-by-step explanation:
Before the point was added, the median was 45. The middle point is the 7th point The 7th point was 45. Now there are 14 points. We add the 7th and 8th points together and divide by 2 (Remember to place a point at 15) (45+45) /2 The median stays at 45
Choice A is the only answer in which the median stays the same
