Answer:
a15 = 50
t25 = 33554427
Step-by-step explanation:
<em>Insert/Substitute the number given in for n.</em>
a15 = 3(15) + 5
a15 = 45 + 5
a15 = 50
~
t25 = 2^25 - 5 <em>2 times itself 25 times. 25 is the exponent in this equation</em>
t25 = 33554432 - 5
t25 = 33554427
Let
A = event that the student is on the honor roll
B = event that the student has a part-time job
C = event that the student is on the honor roll and has a part-time job
We are given
P(A) = 0.40
P(B) = 0.60
P(C) = 0.22
note: P(C) = P(A and B)
We want to find out P(A|B) which is "the probability of getting event A given that we know event B is true". This is a conditional probability
P(A|B) = [P(A and B)]/P(B)
P(A|B) = P(C)/P(B)
P(A|B) = 0.22/0.6
P(A|B) = 0.3667 which is approximate
Convert this to a percentage to get roughly 36.67% and this rounds to 37%

Answer:
x=22.5
Step-by-step explanation:
BM||DT
Using Intercept theorem/Intercept theorem
6(9+x)=9*21
54+6x=189
6x=135
x=22.5
At least I think so
