Answer:

The missing number in the data set is 19

Step-by-step explanation:

The data set is given to be : 12, 17, 21, 13, 25

The median of the data set is given to is 18

Now, to find the median first arrange the data set in the increasing order

So, The data set would be : 12, 13, 17, 21, 25

Now, let the missing number be x

So, The total number of terms in the data set will be 6 that is even.

Now, insert the missing number in between

⇒ The data set will become : 12, 13, 17, x, 21, 25

Now, Median = Mean of 3rd and 4th term

⇒ 18 = Mean of 17 and x

⇒ 18 × 2 = x + 17

⇒ x = 19

Therefore, The missing number in the data set is 19

melissa purchased a car at the price of 20,540 with a down payment of 3,900 and financed the rest paying 8.6% interest compounde
DaniilM [7]

Answer:

$478.06

Step-by-step explanation:

let's first start out by figuring out the present value of the loan

((20540*1.0825)+955+57)-3900

Which gives me a value of 23246.55

I'm then going to assume that the 8.6% is a nominal interest rate meaning that the effectively monthly rate is equal to .086/12=.0072

Which means we have

23246.55=X(a angle 60 at .0072) (i'm using annuities to solve this if you don't know what this is just ask)

Solve this and get $478.06
