Step-by-step explanation:

$800 × 5% = $40

for 1 year, I earn $40

100 ÷ 40 = 2 remainder 2

Therefore I would have to leave the money in for at least 3 years to earn $100

Answer: 2.5 years

Step-by-step explanation:

The formula to calculate the simple interest is given by :-

I=Prt, where P is the principal amount , r is the rate of interest ( in decimal) and t is time ( in years).                                              

Given : P= $800   ; r= 5% =0.05   and  I=$100

Then , we have

100=800\times0.05t\\\\\Rightarrow\ t=\dfrac{100}{800\times0.05}=2.5

Hence, you must leave the money in the account for 2.5 years to earn $100 in interest.

On a multiple-choice test. Abby randomly guesses on all seven questions. Each question
Murrr4er [49]

Answer:

0.173 probability that she gets exactly three questions correct.

Step-by-step explanation:

For each question, there are only two possible outcomes. Either she guesses the correct answer, or she does not. The probability of guessing the correct answer for a question is independent of other questions. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

In which C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

And p is the probability of X happening.

Seven questions:

This means that n = 7

Each question has four choices.

Abby guesses, which means that p = \frac{1}[4} = 0.25

Find the probability to the nearest thousandth, that Abby gets exactly three questions correct.

This is P(X = 3).

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 3) = C_{7,3}.(0.25)^{3}.(0.75)^{4} = 0.173
