5. Multi-Step Problem You are choosing between two electricity providers. The Zap
Electric Company charges $0.06 per kilowatt
hour plus a $6.55 monthly service fee. The
Bolt Electric Company charges $0.12 per
kilowatt hour plus a $2.83 monthly service
fee.
a. Let x represent the number of kilowatt
hours you use in one month, and let y
represent the total cost of your electric
service. Write the two equations represent-
ing the cost of each company's service for
one month.
b. Graph the two equations from part (a) on
the same graph.
c. Estimate the coordinates of the point where
the two graphs intersect.
d. Critical Thinking Explain which compa-
ny to choose if you want to keep your cost
at a minimum and you use an average of
82 kilowatt hours per month.

Apoll is being conducted at a mall nothingto obtain a sample of the population of an entire country. what is the frame for this type of​ sampling? who would be excluded from the survey and how might this affect the results of the​ survey? what is the frame for this type of​ sampling? a. the frame is people who need new clothes. b. the frame is people who shop at the mall. c. the frame is people who like to shop. d. the frame is the entire population of the country. who would be excluded from the survey and how might this affect the results of the​ survey? a. any person that does not need new clothes is excluded. this could result in sampling bias due to undercoverage. b. any person who does not shop at the mall is excluded. this could result in sampling bias due to undercoverage. c. any person who does not shop at the mall is excluded. this could result in nonresponse bias due to people not participating in the poll. d. there is nobody that is being excluded from the survey.

Kevin has a spinner that has 10 equal sections and 2 sections of each color—red, blue, green, yellow, and purple. kevin spins the spinner 180 times. kevin determines about how many times the spinner will land on red or green, and his work is shown below. -kevin has the formula reversed; it should be the total number of sections over the number of red or green sections. -kevin should have used a 4 in the numerator because there are 2 red sections and 2 green sections. -kevin should multiply by the number of sections in the spinner rather than the total number of spins. -kevin calculated the prediction correctly and did not make any mistakes.
