$3100

Step-by-step explanation:

Step one:

given data

Principal = $2500

rate = 1.2%

time = 20 years

Step two:

The simple interest is expressed as

SI= PRT/100

substitute

SI= 2500*1.2*20/100

SI= $600

The account balance after 20 years is

= principal + Simple interest

= 2500+600

= $3100

You invest $700 in an account that pays an interest rate of 6.5%, compounded continuously.
Nina [5.8K]
Please include the instructions when you post a question.  Thanks.

Use the formula A = P*e^(rt).

Here, A = $700*e^(0.065*t), where t is the # of years (which you have not yet included in your post).

As an example:  After 2 years you'll have   A = $700*e^(0.065*2), or A=$797.18, in your account.

Answer:

A) 33.3%

B) 50 %

Step-by-step explanation:

A) if there are 3 balls always in the bucket you need to see what one balk represent one ball is 1÷3 which is 0.33 so by knowing that if Vikram drops the ball back into the bucket after the hit there would be a 33 % chance he will chose the same or a different ball in order.

B)if he won't put the ball back in the bucket there will be only 2 balls felt so 1÷2 = 0.5 so there is a 50 % chance of Victor getting the balls in the correct order

There is a line that includes the point (2, 4) and has a slope of 3. What is its equation in
alexgriva [62]

Answer: y = 3x - 2

Step-by-step explanation:

slope intercept: y = mx + b, where m is the slope and b is the y-intercept.

Thus, because you already know the slope, you can simplify the equation to

y = 3x + b.

Then plug in the provided point to get, 4 = 3(2) + b

4 = 6 + b

-2 = b

Thus,

y = 3x - 2

Hope it helps :)
