Answer:
The 5th day must be 90
Step-by-step explanation:
The first 4 days averaged out to 80
You can find their total just by multiplying by 4. That won't tell you the exact values, but it will tell you their total when you add the 4 of them together.
80*4 = 320
Now you need to add another day into the mix. Call it x
320 + x
Now there are 5 days, not 4, and the new total is 82.
(320 + x) / 5 = 82 Multiply both sides by 5
5*(320 + x) / 5 = 82 *5
320 + x = 410 Subtract 320
-320 -320
x = 90
A common misconception in statistics is confusing correlation with causation. If two events are correlated, it merely means that they share the same behaviour over time, but it doesn't imply in any way that those event are related by a common cause, or even worse, that one implies the other.
You can find several (even humorous) counter examples online. For example, if you plot the number of reported pirates assault against the global temperature in the last years, you'll se that temperature is rising (unfortunately...) while pirates are almost disappearing.
One could observe this strong negative correlation and claim that hotter climate has solved the pirate issue. Of course this is a joke, but it explains why you shouldn't confuse correlation with causation.

Answer:
The total amount of money Shanika and her friends want to raise is <u>$2400</u>.
Step-by-step explanation:
Given:
After a storm damages the community center, Shanika and her friends hold fundraising.
After the first event, they raise $240, which is 10% of the total amount that they want to raise.
Now, to find the total amount of money that Shanika and her friends want to raise.
Let the total amount of money that Shanika and her friends want to raise be .
As given 10% of fundraise is $240.
So, according to question:
<em>Multiplying both sides by 100 we get:</em>
<em>Dividing both sides by 10 we get:</em>
Therefore, the total amount of money Shanika and her friends want to raise is $2400.
