When sarah invests $4,000 in a money market account she receives 1.4% simple interest annually. if she doesn't add or subtract any money how much interest will she earn after 4 years?

Let's use the formula for simple interest: i = p*r*t, where p is the principal amount, r is the interest rate as a decimal fraction, and t is the number of years.

Filling in the given info: i = $4000*0.014*4 = $224.

She will have accumulated $224 in interest over those 4 years.

$224

Step-by-step explanation:

We have been Sarah invests $4,000 in a money market account she receives 1.4% simple interest annually. We are asked to find the amount of interest Sarah will get after 4 years.

We will use simple interest formula to solve our given problem.

, where,

I = Amount of interest after t years,

P = Principal amount,

r = Annual interest rate in decimal form,

t = Time in years.

First of all, we will convert our given interest rate in decimal form:

Upon substituting our given values in simple interest formula, we will get:

Therefore, Sarah will get an amount of $224 in interest after 4 years.

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
