After 3 years a 1500 investment is worth 1680 what is the intrest rate on this investment

The rate of interest for the investment is 3.8

Step-by-step explanation:

Given as :

The Principal = 1500 unit

The Amount after 3 years = 1680  unit

The Time period = 3 years

Let The annual rate of interest = R %

From compounded method

Amount = Principal ×

Or, 1680 = 1500 ×

Or, =

Or, 1.12 =  

Or, = 1 +

Or, 1.038 = 1 +

So, 1.038 - 1 =  

∴  0.038 × 100 = R

I.e R = 3.8

Hence The rate of interest for the investment is 3.8   Answer

a. the are of the rectangle is 18.25

b. 18.25 times two is 36.50

rae me : d

85.560%

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
