Point B is located between points A and C, AB= X^2-10, BC= 2X +2 and AC= 16 ,solve for X

1 answer:

7 0

Drawing a picture would be helpful.
So you have AB and BC, and AC is ALL of AB and BC. In other words,
AC = AB+BC.
Now plug in what the problem gave you.
(16) = (x^2 -10) + (2x + 2)
16 = x^2 + 2x - 8
0 = x^2 + 2x -24
0 = (x+6)(x-4)
x = -6, 4

At Andrew Jackson High School, students are only allowed to enroll in AP U.S. History if they have already taken AP World Histor

o-na [289]

Answer:

About 0.22

Explanation:

There are two sets:

Set W of incoming seniors who took AP World History, and

Set E of incoming seniors who took AP European History

And there is a subset, which is the intersection of those two sets:

Subset W ∩ E of senior students who took both.

The incoming seniors who are allowed to enroll in AP U.S. History, call them the subset S, is the set of those students that belong to W or E or both W ∩E.

By property of sets:

S = W + E - W∩E = 175 + 36 - 33 = 178

Then, 178 out of 825 incoming seniors took one or both courses, and the desired probability of a randomly selected incoming senior is allowed to enroll in AP U.S. History is:

178/825 = 0.21576 ≈ 0.22
