Unlikely , it’s unlikely that you will be within in the 500 foot circle because the odds are slim.
Answer:
40,000
Step-by-step explanation:
Given that:
Percentage Cost price of jewelry = 100%
Jewelery was sold at loss of 5% = (100%- 5%) = 95%
If sold at 5200 more ; profit made = 8%
That is ; (100% + 8%) = 108%
Difference between loss percentage and profit percentage = change in price sold
(108% - 95%) = 5200
13% = 5200
If ;
0.13 = 5200
The percentage cost price = 100% will be;
0.13 = 5200
1 = x
0.13x = 5200
x = 5200 / 0.13
x = 40,000
Answer:
Its 4.6 so close

The first standard deviation covers about 68% of the distribution in a normal curve. (34% higher, 34% lower than the mean). the second standard deviation covers 28% (14% between 1st and 2nd SD above the mean, 14% between 1st and 2nd SD below the mean). In our case
1 Standard deviation = 27 hours (we will approximate to 25 hours)
Mean = 2,000
This means that 34% of the distribution is between 1975 and 2000 hours (within 1 standard deviation below the mean)
2,000- 2,050 covers the range within 50 hours above the mean.
50 hours is roughly 2 standard deviations. The second standard deviation (standard deviation between 1 and 2) covers around 14% on each side of the distribution.
50 hours is roughly 2 standard deviations, which means we add 34% + 14% = 48%.
The range of 1,975 - 2,050 hours covers 34% of the distribution below the mean and 48% of the distribution above the mean.
This means that the probability that the light bulb will last somewhere within this range is 34% + 48% = 82%
The closest answer is 79%. The difference can be explained by the fact that, for simplicity, we approximated the standard deviation to be ~25 hours instead of the real standard deviation of 27 hours.
