The results of a national survey showed that on average, adults sleep 6 hours and 48 mins per night with a standard deviation of 24 minutes. Assume a normal distribution. Answer the following questions by using the Empirical Rules. (Note: you should either use hours or convert to minutes.) a) What percentage of American adults sleep between 5.6 and 6.4 hours per night

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

first you will have to convert 3/4 into a decimal

which is .75

then you will have to divide 1.5 by .75

which is 2

no you have to divide

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify
