Answer:
$1,618.67
Step-by-step explanation:
converting R percent to r a decimal
r = R/100 = 2%/100 = 0.02 per year.
Putting time into years for simplicity,
7 months / 12 months/year = 0.583333 years.
Solving our equation:
A = 1600(1 + (0.02 × 0.583333)) = 1618.666656
A = $1,618.67
The total amount accrued, principal plus interest, from simple interest on a principal of $1,600.00 at a rate of 2% per year for 0.583333 years (7 months) is $1,618.67.
Answer: 1120
Step-by-step explanation:
Since 12 out of every 180 frogs in the popluation have spots on their back, this means that (180 - 12) = 168 do not have spot on their back. This can be represented in a fraction as:.= 168/180 = 14 / 15
With a study of a population of 1,200 frogs, the number of frogs that do not have a spots on their back will be:
= 14/15 × 1200
= 1120
Multiply each X by its corresponding probability P, then add up them up.
E[X] = 3•0.2 + 4•0.1 + 5•0.25 + 7•0.05 + 9•0.4
⇒ E[X] = 6.2
