Susan currently has an account balance of $1,336.60. Her initial deposit on the account was $820 and it earned 4.5% simple inter
emmasim [6.3K]

The correct option will be :   14 years

<u><em>Explanation</em></u>

Current account balance of Susan is $1,336.60 and her initial deposit was $820

So, the amount of interest earned = 1336.60-820= 516.60 dollar

Formula for Simple Interest is: I= P*r*t, where I is the amount of interest, P is the initial amount, r is the rate of interest in decimal and t is the time duration in years.

Here, I= 516.60, P= 820, r=4.5% = 0.045

Now according to the above formula, we will get...

I= P*r*t\\\\ 516.60=820*0.045*t\\\\ 516.60=36.90*t\\\\ t=\frac{516.60}{36.90}= 14

So, Susan has held the account for 14 years.

A bookbook can be classified as either non dash fictionnon-fiction or fictionfiction. Suppose that 9494​% of booksbooks are clas
DIA [1.3K]

Answer:

a) 0.8836

b) 0.7339

c) 0.2342

Step-by-step explanation:

Books classified as fiction = 94% or 0.94 probability

Books classified as non-fiction = 1 - 0.94 = 0.06

a) for two books, we get: 0.94 * 0.94 = 0.8836 Probability

b) The probability that all five books are fiction is: 0.94^5

    This equals 0.7339 Probability

c) Probability that one books is non-fiction, while the other 4 are fiction is determined in the following way:

 Probability of non-fiction * probability of fiction^(number of books)

 0.06 * 0.94^4 = 0.0468

 This does not account for the order at which the non-fiction book shows up. Such as the non-fiction book being the first book picked, or in another case - the non-fiction book being the last picked.

Since there are 5 ways this could occur, the total probability will be calculated as shown: 0.0468 * 5 = 0.2342 Probability
