Each pad of paper cost 3.25. Here is how I found it.
21.75 x 3 = 65.25
75 - 65.25 = 9.75
9.75 / 3 = 3.25
X = 3.25
Is this what you were looking for?
Initially = 80 pounds
It triples every 2 hours
2 hours later = 3(80)
4 hours later = 3(3(80)))
6 hours later = 3(3(3(80)))
8 hours later = 3(3(3(3(3(80)))))
8 hours later =

x 80
8 hours later =
6480 (Answer C)
OR
We find the number of 2 hours period in that 8 hours
8 ÷ 2 = 4
It starts at 80 pounds
It tripes every 2 hours
Total algae =

x 80 =
6480 (Answer C)
The sample size is, 9604 if you want to obtain a sample to estimate a population proportion at this point in time, you have no reasonable estimate for the population proportion.
<h3>What is the margin of error(MOE)?</h3>
It is defined as an error that gives an idea about the percentage of errors that exist in the real statistical data.
As we know, the sample size can be evaluated using the expression:

or

Here ME = 1% = 0.01
p = 0.5, q = 0.5
Z at α 0.05 (because 95% confident)
= 1.960

n = 9604
Thus, the sample size is, 9604 if you want to obtain a sample to estimate a population proportion at this point in time, you have no reasonable estimate for the population proportion.

Answer:
$725
Step-by-step explanation:
First, find how much money she made from selling 65 cups:
65(15)
= 975
Subtract the $250 that she spent on the bag of grapes:
975 - 250
= 725
So, her profit was $725
Answer:
The machine can make 24 soda bottles each minute
Step-by-step explanation:
We can find the number of bottles the machine can make using the slope formula
Mathematically, this can be given as;
m = (y2-y1)/(x2-x1)
m = (192-120)/(8-5) = 72/3
m = 24
