How do you find the frequency in frequency table if the given is percent of total?
find the frequency before finding the percent total
-_- :)
What is the essence of finding the standard deviation of your data?
I am not entirely sure I understand correctly what you mean by "essence". However, the idea of finding the standard deviation is to determine, as a general tendency, whether most data points are close to the average, or whether there is a large spread in the data. The standard deviation means, more or less, "How far is the typical data point from the average?"
If a center line and a hidden line coincide with one another which line is drawn?
The hidden line is drawn, however, the edges of the center line can still be seen ( the center line ends up appearing as extra long dashes on either side of the end of the hidden line)
How many gallons does your 1997 Saturn SL1 gas tank hold?
12.8 us gallons
---
Actually, it's 12.2 gallons. 1996 was the last model year the S-Series had the 12.8 gallon tank. The size was changed to add a "Low Fuel" Sensor in the 1997 models that the 1996 models (and before) did not have. 1996 is 12.9 gallons
Is the mean of a set not affected by outliers?
FALSE
The mean is the MOST affected by the outlier.
Example:
<- 1 2 3 4 5 9 ->
9 is the outlier
1 + 2 + 3 + 4 + 5 + 9 = 24
Divided by 6 = 4
Without 9 the solution is this:
1 + 2 + 3 + 4 + 5 = 15
Divided by 5 = 3
The median and mode are also affected.
What are the chances of getting tails at least twice if you throw a coin four times?
.5 or 50% probability (if not counting draws)

How many 3 digit codes using 0 through 9 are possible if repetITIONS are allowed?
1,000 of them.
The list of possibilities will look exactly like the counting numbers from 000 to 999 .
Nothing, since there is no such word. Perhaps you should consider spell-checking your questions before posting them!
What does the range in a box plot tell us?
It tells you how much larger the largest observation is compared to the smallest.
What is the P TTT on three flips of a coin?
P(T) = 1/2
Since you want to flip 3 T's in a row, you multiply.
P(TTT) = 1/2 * 1/2 * 1/2 = 1/8
What does reduce mean in mathematical terms?
it mean to subtract the number or add the number. i am a professor so i know what u r talking about so if this works just leave a comment. No bad ones.

The [mean] average of 5 numbers is 25, so their total is 5 x 25 = 125
The [mean] average of 4 numbers is 25, so their total is 4 x 25 = 100
→ the excluded number is 125 - 100 = 25.
Alternatively, as the average doesn't change, the excluded number must be the average, ie 25.
