I need help with this someone very smart in math this is algebra 2

D

Step-by-step explanation:

The interest is compounded annually, which means that interest from the previous year earns you even more money next year.

It should be obvious that after one year Alexis will have

$475 + $475 * 1.25% = $475 * 100% + $475 * 1.25% =

= 101.25% * $475 = 1.0125 * $475

Then, next year she would have

1.0125 * $475 + (1.0125 * $475) * 1.25% =

= (1.0125 * $475) * 1.0125 = 1.0125^2 * $475

See the pattern?

Alexis will have $475 * 1.0125^x after x years.

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
