Answer:
13) C (a, a) Y (a, 0)
14) B (0, b) P (a, 0)
Step-by-step explanation:
13) Y lies on x axis so it is Y(a,0)
ZY = YC = a
so for C coordinates are (ZY,YC) = (a, a)
14) B lies on y axis so it is B(0, b)
BK = BP =
= distance between two points
so P is (a, 0) as it is same distance and on positive side of x axis

Hey there!
We don't have enough information. 7(n+5) can be written as either the 7 times the sum of n+5, or 7 multiplied by n+5.
Let me know if this helps :)
Answer:

Step-by-step explanation:
We are given that
Sophomores=13
Juniors=12
Seniors=8
Male sophomores=5
Female sophomores=6
Male seniors=4
We have to find the probability of randomly selecting a junior or a senior.
Total persons=13+12+8=33
Let A=Seniors
B=Juniors
Probability,P(E)=
Using the formula of probability







Hence, the probability of selecting a junior or senior=
