Solution
For this case we can do the following:
Part 2
17/50 represent the conditional probability of being vegetarian given that the person selected is female
Part 3
17% of students surveyed were female vegetarians
Is a joint relative since represent the % of vegetarians and female in all the sample
There are 900 calories in 180 crackers. Write 60 calories for 12 crackers as 60/12. Then make x/180, showing that there are 180 crackers with an unknown amount of calories. Cross multiply 60 and 180, which is 10,800. Divide 10,800 by 12, and you get 900.

1, 3, 5, 7, 9 are the possible digits for the tens digit. Notice they are all odd.
My reasoning:
</span><span>
When you multiply any 2 numbers together, the last digit of the result will be the last digit of the product of the original last digits (ex. 12*7 = 84: 7*2 = 14 : 4 is last digit)
</span>
The last TWO digits of the result will be the same as the last 2 digits of the product of just the last two digits. (ex, 1422*234 = 332,748: 22*48 = 748 : 48 are last two digits )
If is a perfect square ends in 6, the last digit squared must end in 6 as well.
The only single digit numbers squared that end in 6 are: 4*4=16 and 6*6=36
They are the only 2 so the number that is being squared must end in 4 or 6
Let the second last digit be X. X can be any digit.
So the last 2 digits of our number that is being squared are either X6 or X4
That is, the last 2 digits of the number are either (10X+6) or (10X+4),
this will result in X always being an odd number.
Answer:
n = 35
Step-by-step explanation:
35 divided by 7 gets you 5.
