The formula for compound interest, compounded once per year, is:
A = P(1+r)^t, where r is the annual interest rate as a decimal fraction and t is the number of years.
If interest is compounded twice per year, then the above formula is changed to:
A = P(1+r/2)^(2t), where the '2' indicates twice-per-year compounding.
If interest is compounded n times per year, then the above formula is changed to:
A = P(1+r/n)^(nt).
Volumes are in ratio 27 : 1331
so ratio od individual lengths = cube roots = 3 : 11
and surface areas will be in the ratio 3^2 : 11^2 = 9:121
so surface area of the larger figure is 121 * 18 / 9 = 242 mm^2
The answer is a. Because at approximately 17 weeks the two lines meet.
The probability that the person pulls 1 blue M&M given that one is only allowed to pull 5 random M&M's per day will be 0.6450.
<h3>How to calculate probability?</h3>
From the information given, there are 1,023 M&M's in a bag and out of 1,023 M&M's, 132 M&M's are blue.
Therefore, the probability of getting a blue M&M will be:
= 132/1023
= 0.1290
Therefore, since the person is given the chance to pull 5 random M&M's per day, the probability will be:
= 0.1290 × 5
= 0.6450
