38+39+40 = 117.
So the first of the three numbers is 38.
Step-by-step explanation:
The question is not properly structured but we can as well find the sum of 5/7 and 10 as shown;

Hence the expression written in equivalent form of common denominator is 
The sum is 
Answer:
Buffalo
Thats the answer because temp is decreasing back so 10 is higher plus lower than all
Probability of rolling a sum of 9 or a sum that is even from two number cubes is
11/18
Explanation:
When a dice is rolled there are different ways in which
9. can be obtained, which are (3,6) or (4,5) or (5,4) or (6,3). 4 options. As in all there are
6⋅6=36 options, probability is 4/36 or 1/9.
For getting an even number as sum, we can have (1,1) or (1.3) or (1,5) or (2,2) or (2,4) or (2,6) or (3,1) or (3,3) or (3,5) or (4,2) or (4,4) or (4,6) or (5,1) or (5,3) or (5,5) or (6,2) or (6,4) or (6,6) 18 options, probability is 18/36 or 1/2.
Note that the two events (getting 9 or even sum) are mutually exclusive, the probabilities can be just added i.e. combined probability is
1/9+1/2=2+9/18i.e. 11/18
for mean you add every number and divide it by the amount of numbers in the data set
for median you put the numbers in order and find the middle number, if there is no middle get the mean for the two middle numbers
range is basically the lowest and highest number
