Answer:
a) 30
b) 88
c) 70
d) 16
e) 160
f) 250
Step-by-step explanation:
So the first step would be to switch the numbers around. For example A would be 15 and 50 instead of the original order of 50 and 15. You would then take the 1st number in the new arranged order (15) and multiply it by 100, then divide in that order. 1500/50 = 30.
Another example, letter B.
Step 1 - Rearrange : 22 and 25
Step 2 - Multiple by 100 = 2200
Step 3 - Divide : 2200/25 = 88
Good Luck :) Hope this helped.
Method 2 is the least biased.
1) vegetarians are a select group, so they might have a certain biased perspective
2) if students are chosen randomly from every grade, all grades are included and there will be a variety of responses
3)not all students dislike the program, so it is an unfair representation
4)only students who have a strong opinion will complete the survey
A' = (-2, 1)
B' = (1, 0)
C' = (-1, 0)
To get the value of n u have to set n by itself, first we have to set teh smallest n to teh other side this will give you 0=8+2n now subtract the 8 from both sides because it is positive and the only way to get rid of a positive is with a negative this will give you -8=2n, now to set n by itself divide by 2 in both sides because in order to get rid of a multiplication you have to divide, this will give you n=-4, so your answer will be letter A
Hope this helps
