Suppose that motorists in the southeastern Unites States use a mean of 8.20 gallons of gasoline per week with a standard deviation of 0.47 gallons. Assume that gasoline consumption levels are normally distributed. a) What percentage of southeastern drivers use more than 9.0 gallons of gasoline per week

because they could drop even lower..

lol we need to see what the question is asking about

step-by-step explanation:

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!
