Answer:
Values less than -3 or values greater than 3 make the disjunction true
P V Q means that either p or q or both must be true to be a true statement so it includes x is less than -3 (p) and x is greater than 3 (q).
Step-by-step explanation:
Answer:
The answer is b
Step-by-step explanation:
Very simple. You just use the vectors as normal numbers, and multiply the coordinates with 2 and 4 like this:
2*u = 2* (2,4) = (4,8)
4*w = 4* (-1,3) = (-4,12)
(4,8) - (-4,12) = (8,-4)
So the vector has the coordinates (8,-4)
The percentage of students that graduated from college that also attended a high school is given as 0.7792 or 77.92 percent.
<h3>How to solve for the probability?</h3>
We have the Prob(attended public school | graduated)
The probability that a person attended public school and graduated as
Prob (P and G) = 0.80 x 0.75
= 0.6
The probability that a person graduated is given as
0.8*0.75 + (1 - 0.8 * 0.85)
= 0.6 + 0.17
= 0.77
Prob(P and G ) /Prob(G)
= 0.6 / 0.77
= 0.7792
The percentage is given as 77.92%
