The physical plant at the main campus of a large state university receives daily requests to replace florecent lightbulbs. The distribution of the number daily requests is bell shaped and has a mean of 51 and a standard deviation of 6. Using the empirical rule what is the approximate percentage of lightbulbs replacement requests numbering between 33 and 51?​

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!

set the two equations for y equal to each other. solve for x. this will be the x-coordinate for the point of intersection. use this x-coordinate and plug it into either of the original equations for the lines and solve for y.
