Answer:
B. Events H and C are dependent and P(H|C) < P(C|H)
Step-by-step explanation:
The ratios of groups with children to hiking groups on the trail are different for the two trails.
P(H|C) = 15/45 = 1/3
P(C|H) = 15/40 = 3/8
1/3 < 3/8 so the comparison of choice B is appropriate.
12.5
12=96x/100
x=(100*12)/96
x=1200/96
x=12.5
0.2(3) reoccurring.
Easiest way I can think of is to just put it in to a calculator and convert to a fraction, haha. Have fun counting up reoccurring numbers manually.
The answer is
325/360=120 πr2
325 πr2/325 π=120.360/325 π
R2=42.3
R=6.5cm is your answer
Answer:
5.1% (nearest tenth)
Step-by-step explanation:
<u>Annual Compound Interest Formula</u>

where:
- A = final amount
- P = principal amount
- r = interest rate (in decimal form)
- t = time (in years)
Given:
- A = $2,209
- P = $2,000
- t = 2 years
Substitute the given values into the formula and solve for r:







Therefore, the annual interest rate is 5.1% (nearest tenth)
