Answer:
Sample B is much bigger than Sample A
Step-by-step explanation:
It is because when seeing sample B alone we can see it has a larger mean than of Sample A. Mean is greater when the values we are using are of bigger value. Since Sample B has bigger values in it so it also a has bigger mean compared to Sample A which has a smaller mean (smaller values in it)
The correct answer is D.
the total calorie intake mark wants is 510.
He takes 30 for side dish (30s) and 45 for entree (45e)
therefore 30s + 45e = 510
now that you have an equation, judging by the choice of answers given... you have to make s the subject of formula
30s + 45 e can be factorised to 15(2s+3e) = 510
divide 510 / 15 = 34
now we have 2s + 3e = 34
hence 2s = 34 - 3e
didvide by 2 to make s 'free'
therfore you'll get s = 17-(3/2)e
Hope this helps! :)
