- r: interest rate (convert to a decimal)
- n: number of times compounded per year
- t: number of years

b)


21, 45, 121, 300, 312, 333, 347, 421, 614,
The median is the middle number of a data set therefore you need to arrange the data is order from smallest to largest as I have done above. Then you need to find the number in the middle which is 312 in this case by finding the number which has the central position (position 5 in this case) of the data set. If there are an even number of numbers in the data set, you add them together and divide by 2 though that is not necessary this time as there are an odd number of numbers.

Answer:
C
Step-by-step explanation:
3x^2 * -x =-3x^3
3x^2 * 2. =6x^2
4x* -x =-4x^2
4x * 2 = 8x
-5 * -x = 5x
-5 * 2 = -10
6x^2 + -4x^2 = 2x^2
8x+5x = 13 x
Ans: -3x^3 + 2x^2 + 13x -10
