Last one, triangles AOB and COD
Step-by-step explanation:
In step 3, they are talking about the side/angle/side postulate. That helps in describing a triangle, therefore she must be talking about a triangle
Answer: The probability he didn't take an SAT prep course = 0.985
Step-by-step explanation:
Let us first assume that he took SAT prep.
Surveys indicate that 5% of the students who took the SATs had enrolled in an SAT prep course. 30% of the SAT prep students were admitted to their first choice college. That is,
30/ 100 of 5 = 0.3 × 5 = 1.5
The probability he did take an SAT prep course and got admission into the college of first choice will be
P(prep) = 1.5 / 100 = 0.015
The probability he didn't take an SAT prep course will be:
P(not prep) = 1 - P(prep)
P(not prep) = 1 - 0.015
P(not prep) = 0.985

Answer:
FV(n)=42,000(1.04)^n
Step-by-step explanation:
FV=PV(1+r/n)^nt
Where
FV=future value
PV=present value
r=interest rate
n=number of periods
t=time (years)
PV=42,000
r=4%=0.04
n=1
t=n
FV(n)=p(1+r/n)^nt
=42,000(1+0.04/1)^1*n
=420000(1+0.04)^n
=42,000(1.04)^n
FV(n)=42,000(1.04)^n
