290-10=280
280 is one standard deviation below.
All that are above mean is 50%.
One standard deviation below is 34%.
50%+34%=84% all of these bags weigh more than 280 g.
So,
100%-84%=16% should be bags that are less than 280 g.
Answer is b) 16 %.
the answer would be x=1 because if u do the math u get 3/2 and that simplified is 1 so this how i got the answer not 100% sure though but thats what i got
<span> 1.09/12=0.091 18 eggs is a better buy</span>
Y=(m)(x)+b
so you already have the slope=-6/5 and the intercept is 3
y=-(6/5)x+3
I do not understand your question could you please be more descriptive
