Answer: 34%
Step-by-step explanation:
Given : The distribution of the number of daily requests is bell-shaped and has a mean of 59 and a standard deviation of 7.
i.e. and
According to the 68-95-99.7 rule, about 68% of the population lies in one standard deviation from the mean.
About 34% of the population lies one standard deviation above the mean and About 34% of the population lies one standard deviation below the mean.
For the given situation, 34% of lightbulb replacement requests lies one standard deviation below the mean .
i.e.About 34% of lightbulb replacement requests lies between and .
i.e. About 34% of lightbulb replacement requests lies between and .
i.e. About 34% of lightbulb replacement requests lies between and .
Hence, the approximate percentage of lightbulb replacement requests numbering between 52 and 59 = 34%
Answer:
Distance from Earth to Proxima Centauri (in scientific notation) = kilometers
Step-by-step explanation:
We need the conversion between Astronomical Unit and Kilometers.
The conversion is:
1 AU = 1.496*10^8 km
or rounded, given in this problem,
1 AU = km
We need the distance from Earth to Proxima Centauri:
AU * kilometers
When multiplying two numbers in scientific notation, we have to "multiply the coefficients" and "add the exponents".
Lets do this:
Distance from Earth to Proxima Centauri (in scientific notation) = kilometers
