Ad libitum [116K]
You don't list the "sums listed below" but I can still help you.
There are 6 ways to get a sum of 7 using a pair of dice:
1+6
6+1    You might be asking why 2+5 isn't the same as 5+2
2+5      Imagine the dice are different colors.  Is a red 2 and green 5 the
5+2          same as a green 2 and red 5?  (No, it's not)
3+4
4+3
You need two numbers that also provide 6 ways to win.  One pair that would work is 11 and 9   There are two ways to make 11 (5+6) and (6+5)  and there are four ways to make 9 (3+6), (6+3) (4+5) and (5+4) - that's a total of six ways.  So to balance your friend's 7 - you could go for sums of 11's and 9's.  Check the choices you were given and find the numbers (it could be three numbers like 2,3, and 12) that give you 6 ways to win.
Here are the numbers and their ways

The table below shows the lowest temperature, in degrees fahrenheit, on each of 5 days. What is is mean lowest temperature, in d
Yuki888 [10]

Answer: -7

Step-by-step explanation:

To calculate mean , the formula is given by:-

Mean=\frac{\text{Sum of all observations }}{\text{Number of all observations}}

From the given values of temperature in the table.

The sum of temperature in degrees Fahrenheit, in the city for those 5 days is given by S=-36+(-25)+12+(-4)+18=-36-25+12-4+18\\\Rightarrow\ S=-35

The number of days N = 5

So the mean lowest temperature, in degrees fahrenheit, in the city for those 5 days is given by:-

Mean=\frac{S}{N}=\frac{-35}{5}=-7
