Answer:
RP=15
x=14
Step-by-step explanation:
ΔJKL≅ΔPQR so JK=PQ, KL=QR, and JL=PR.
KL=3y-2 and QR=22
So, 3y-2=22 and 3y=24 and y=8
Now, that we know y=8 we can plug it in 2y-1 to find RP
2(8)-1=16-1=15
In congruent triangles, the corresponding angles are also congruent.
So, ∠K≅∠Q
∠K=42 and ∠Q=3x
So, 42=3x and x=14

Answer:
Mean is 19.43
Standard deviation is 2.5322
Step-by-step explanation:
For each student who graduated from high school in 2012, there are only two possible outcomes. Either they have enrolled in college, or they have not. The probability of a student having enrolled in college is independent of other students. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The expected value of the binomial distribution is:
The standard deviation of the binomial distribution is:
67% of students who graduated from high school in 2012 enrolled in college.
This means that
Sample of 29 high school graduates
This means that
Mean
Standard deviation
