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%
So the question is asking what is 6.2% of 1000? Then rounding our decimals?
If you search the internet you can find the answer I hope you can find the answer
So, you have $12,678. However, you want to earn $42,000 for a new car. If you want to figure out how much money you need, you need to subtract the number of money you want to earn by the number of money that you already have:
You would need
$29,322 more in order to buy the car.
