Answer:
c) at most 11.1%
Step-by-step explanation:
We have the data that is 97 ± 12, with 97 being the mean and 12 the standard deviation.
Now, the percentage of people who reached them for less than 73 dollars, if it were a normal distribution:
z = (73 - 97) / 12 = - 2
so it would be, a probability of 0.0228 or 0.228%.
But we don't know what distribution it has, but we can get an idea.
A and D discarded, as they are very high values, and 73 is well below the average.
B) is still a very high value.
Therefore the answer is C, at most 11.1%
Answer
First you would divide both sides by 2y so it would be
x/2y = z

Step-by-step explanation:
(-2/3 )x (1/6)
Cross Multiply:
.... so the 2 and 6 would become 1 and 3
..... Like that
..... (3x3=9)
