Question 17

The variable is the exponent whats the rule??

Answer 17

It will always be common base elimination, we dont have log OR desmos so it will be that in any situation where the exponent is the variable, regardless of if its financial or half life or whatever.

Question 18

we had to solve for a unknown interest rate, now that we have it as i = decimal what do we do???

Answer 18

decimal(100)= interest % this will make sure we dont mess it up, the result is an amazing heuristic for determining if we screwed up the interest rate calc

Question 19

we have our rise/run for equation of a line now what

Answer 19

use a given point on our line such as (1,5) and plug it in with our slope (4)
y=mx+b
5=2(1)+b
5=2+b
5-2=2-2+b
3=b

y=2x+3

Question 20

Whats first differences

Answer 20

first differences are numbers that represent the difference between the 2 y points on 2 sequential x points for example

(3,6)
(4,8)
(5,10)

we clearly see a constant first difference of 2, this is basically its rise/run value

Question 21

we need to do percentile for the list 1,2,3,4,5,6,7,8,9,10,11,12,13,14 the value we need to calculate the percentile of is 10…………what will the formula look like

Question 22

we need to do percentile for the list 1,2,3,4,5,6,7,8,9,10,11,12,13,14 but our value we need to add to the list and find the percentile, this number is 10…………what will the formula look like

Question 23
