What is the equation for compound interest

1 answer:

3 0

A = P(1 + r)^n

where A is the amount after n years, P = principal( initial amount), r = annual rate as a decimal fraction and n = number of years

If interest is accumulated say monthly then it would be

A = P(1 + r/12)^12n

For quarterly replace the 12 by 4

Answer:

45 minutes

Step-by-step explanation:

Assume task completed in total x hours

$\frac{x}{10} + \frac{3}{8} + \frac{3}{12} = 1 \\ 12x + 45 + 30 = 120 \\ 12x = 45 \\ x = \frac{15}{4} = 3 \frac{3}{4}$

Find the median and mode of this set of data 5 , 1, 3, 5, 8 , 10, 8, 14

kobusy [5.1K]

Answer:

Mode: 5 and 8

Median: 6.5

Step-by-step explanation:

Mode - the number that appears the most in a set of data. There may be no mode ( when no number out numbers the others) or multiple modes ( multiple numbers appear the same number of times). Both 5 and 8 appear twice in this set.

Median - The middle number. To start, order your numbers from least to greatest.

1, 3, 5, 5, 8, 8, 10, 14

You have an even set of numbers (8 in total), which means there won't be one number left in the middle. In this situation, there are two: 5 and 8. So you just need to add them together and divide by 2

8 + 5 = 13

13/ 2 = 6.5
