In f(x) = 16(0.75)x the (0.75) does not have a 1 so it is decreasing and if it is only 75% of 16 then it would be losing 25% each time So the exponential decay will be 25%.
The answer is 6 schools.
In a box and whisker plot, every piece of whisker or box represents 25% of the whole number of schools.
The schools participated 1 year or less are represented by the left part of the whisker. Which stands for 25%.
To make an equation we need to set 100% = 24 and solve for 25% :

Set the denominators equal:

Remove the denominators and solve:
Answer:
P = $300
r = 0.15
n = 12
$544.61 (to the nearest cent)

$524.70 (to the nearest cent)
Step-by-step explanation:
P = principal amount = $300
r = annual interest rate in decimal form = 15% = 15/100 = 0.15
n = number of times interest is compounded per unit t = 12
<u>How much she'll owe in 4 years</u>
P = 300
r = 0.15
n = 12
t = 4

= $544.61 (to the nearest cent)
<u>Yearly compounding interest rate</u>
<u />
<u>How much she'll owe in 4 years at yearly compounding interest</u>
<u />
= $524.70 (to the nearest cent)
Tried a whole bunch of odd sequences:
11 + 13 + 15 = 39
Nope too small.
21 + 23 + 25 = 69
Woah too big!
And after a few more trials found that:
17 + 19 + 21 = 51
Woohoo!
