To find the simplified form of (6/7)^2, you have to break the bracket and square both the denominator and the numerator. (6/7)^2=6^2/7^2=36/49.

Mrs Shakya sold a jewellery at a loss of 5%.If she had sold it at Rs,5200 more she would have gained 8% .Find the cost price of
Georgia [21]

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

The life expectancy of a typical lightbulb is normally distributed with a mean of 2,000 hours and a standard deviation of 27 hou
LiRa [457]
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.
