2. Probability of the mail being delivered before 2 pm for 2 consecutive days is
3. take a look at the picture attached, the tree diagram is another method we could use.
Answer:
$70,201.38
Step-by-step explanation:
To determine the principal amount, we can use the formula:

A = $200,000
r = 7% or 0.07
t = 15 years
n = 12

So the principal needed to get 200,000 in 15 years is $70,201.38.
$2 can get you one candy bar. So if you want 6 it would cost $12
A square field that is 1/4 mile long and 1/4 mile wide has area
