A survey of 85 randomly selected homeowners finds that they spend a mean of $67 per month on internet. Assume that the population standard deviation is $14 per month. a) Construct and interpret a 99% confidence interval estimate for the mean amount of money spent per month on internet by all homeowners.
b) Does the confidence interval support that internet costs more than $60 per month? Why or why not?

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.

i think its 7.6
