Answer:

1.  money in the account = 400 + 6t   where t is the number of years

2. Total cost = principal ( 1+ rate* time)

Step-by-step explanation:

1.  The formula for simple interest is  I = PRT where

   P = principal

  R is the interest rate

  T is the time in years


I = 400 * .015 * t

I = 6t  where t is the number of year

The amount of money in the account is the principal plus the interest

money in the account = 400 + 6t

Since we were not given the time period,   I will  leave it here.


2.  Since we are paying simple interest

The formula for simple interest is  I = PRT where

   P = principal

  R is the interest rate

  T is the time in years

We can figure out what the total interest is

Add it to the amount of the principal

The total amount you will pay on the loan is

Total cost = Principal + interest

                = principal + principal * rate * time

                 = principal ( 1+ rate* time)

Marat540 [252]

Answer:

7/30 of her music library

Step-by-step explanation:

We are looking for 7/10 of 1/3. In this case this "of" means we will multiply the two fractions. To multiply fractions, we multiply

top × top

and

bottom × bottom

1/3 × 7/10

is 1×7 on top, and

3×10 on the bottom.

= (1×7)/(3×10)

= 7/30

7/30 cannot be simplified, so that is the answer.

ELEN [110]

Answer:

Complete the following statements. In general, 50% of the values in a data set lie at or below the median. 75% of the values in a data set lie at or below the third quartile (Q3). If a sample consists of 500 test scores, of them 0.5*500 = 250 would be at or below the median. If a sample consists of 500 test scores, of them 0.75*500 = 375 would be at or above the first quartile (Q1).

Step-by-step explanation:

The median separates the upper half from the lower half of a set. So 50% of the values in a data set lie at or below the median, and 50% lie at or above the median.

The first quartile(Q1) separates the lower 25% from the upper 75% of a set. So 25% of the values in a data set lie at or below the first quartile, and 75% of the values in a data set lie at or above the first quartile.

The third quartile(Q3) separates the lower 75% from the upper 25% of a set. So 75% of the values in a data set lie at or below the third quartile, and 25% of the values in a data set lie at or the third quartile.

The answer is:

Complete the following statements. In general, 50% of the values in a data set lie at or below the median. 75% of the values in a data set lie at or below the third quartile (Q3). If a sample consists of 500 test scores, of them 0.5*500 = 250 would be at or below the median. If a sample consists of 500 test scores, of them 0.75*500 = 375 would be at or above the first quartile (Q1).
