The answer is D) 2
Since it is given that there have been 9 slices eaten, we can assume that whatever amount of slices were cut in total will have 9 reduced from the amount. With the fraction 2/11, we know 11-9=2, which fits perfectly into this description so 2 slices have not been eaten.
A-b = 43----(1)
a+b = 13----(2)
(1)+(2) 2a=56
then a=56/2= 28
so b=13-28= -15
so that the numbers are -15 and 28
Y=-3 would be the correct answer:)
Answer:
16%.
Step-by-step explanation:
We may assume that the times are normally distributed.
We first find the z-score which is the (value - mean) / standard deviation.
z-score = (4 - 6)/2 = -1.
Looking up the value for -1 on a z-score normal distribution table we find that -1 gives us 0.1587 - that is 16%.
