Lynne invested $35,000 into an account earning 4% annual interest compounded quarterly. She makes no other deposits into the account and does not withdraw any money. What is the balance of Lynne's account in 5 years?

Answers

The interest earned on the amount will increase the net balance. The balance of Lynne's account in 5 years would become $76,689.31 approximately.

How to calculate compound interest's amount?

If the initial amount (also called as principal amount) is P, and the interest rate is R% per unit time, and it is left for T unit of time for that simple interest, then the interest amount earned is given by:

And thus, final amount will be:

For the given case, the principal amount (initial amount) Lynne invested is P = 35000 (in dollars)

The rate of interest = 4% compounding quarterly.

Here, unit of time is is quarter of an year which means 1/4 of an year.

The time is given to be 5 years. In each year, there are 4 quarters, so in 5 years, there would be 20 quarters of years.

Thus, T = 20 (we always need to keep unit of time same for R and T for using that formula).

Putting these values in the above formula, we get the final amount's value in Lynne's account in 5 years as:

Thus, the balance of Lynne's account in 5 years would become $76,689.31 approximately.

Data:
P = 35000
r = 4% = 0,04
n = 4
t = 5
P' = ?
I = ?

We have the following compound interest formula










So the new principal  after 5 years is approximately $42,706.66.

Subtracting the original principal from this amount gives the amount of interest received:

Simplify 2a^2b^3(4a^2+3ab^2-ab)

Answers

2a^2b^3(4a^2+3ab^2-ab)=? 

is what I presume you actually meant. 

Pull out the common factors of (4a^2+3ab^2-ab) and you will get 

a(4a+3b^2 -b) 

Substitute this back into the original equation and you get 

2a^2b^3[a(4a+3b^2-b)] = 
2a^3b^3(4a+3b^2-b) =

What is the complementary event to drawing a blue marble? (check all that apply) drawing a red marble


drawing a green marble


drawing a red or green marble


not drawing a blue marble


PLZ hurry I give brainly

Answers

Answer: Fourth Option is correct.

Step-by-step explanation:

Since we have given that

let A be the event of drawing a blue marble.

We need to find the complement of event A i.e. represented by A'.

Complement of any set of all the outcomes that are not the event.

So, A' would be the event of not drawing a blue marble.

Hence, Fourth Option is correct.

In Janie’s homeroom, 45% of the students’ families own a dog and 23% own a dog and a cat. What is the probability that a student’s family owns a cat if the family owns a dog?

Answers

Answer:

51,111%

Step-by-step explanation:

We know that 45% have a dog but no cat.  While 23% have both a dog and a cat.

Then Pr(X has cat|X has dog) = Pr(X has dog and cat)/Pr(X has dog)

= Pr(X has dog and cat)/Pr(X has dog) = 0.23/0.45 = 0.51 ≈ 51,111%

The probability that a student’s family owns a cat if the family owns a dog is 51,111%

Answer:

51.1% is the correct answer.
