^Challenge^. A cell phone plan costs $27.70 per month for 800 minutes of talk time. It costs an
additional $0.05 per minute for each minute over 800 minutes. To get e-mail access, it costs 10% 0
the price for 800 minutes of talk time. Your bill, which includes e-mail, is the same each month for 7
months. The total cost for all 7 months is $234.29. Write and solve an equation to find the number
minutes of talk time you use each month.

Let m represent the number of minutes over 800 minutes each month. Which equation represents the given
situation?

A 234.29 = 7(m + 27.70)
B. 234.29 = 7(0.05m +27.70+ 0.10(27.70))
C. 234.29 = 7(m + 27.70 +0.90(27.70))
D. 234.29 = 7(0.05m +27.70)
You use _? minutes of talk time each month.?

Solving algebraic equations 2m+3=11

Do you mind if you guys me with this question i’m on number 8

In a test for esp (extrasensory perception), the experimenter looks at cards that are hidden from the subject. each card contains either a star, a circle, a wave, a cross or a square.(five shapes) as the experimenter looks at each of 20 cards in turn, the subject names the shape on the card. when the esp study described above discovers a subject whose performance appears to be better than guessing, the study continues at greater length. the experimenter looks at many cards bearing one of five shapes (star, square, circle, wave, and cross) in an order determined by random numbers. the subject cannot see the experimenter as he looks at each card in turn, in order to avoid any possible nonverbal clues. the answers of a subject who does not have esp should be independent observations, each with probability 1/5 of success. we record 1000 attempts. which of the following assumptions must be met in order to solve this problem? it's reasonable to assume normality 0.8(1000), 0.2(1000)%30 approximately normal 0.8(1000), 0.2(1000)% 10 approximately normal srs it is reasonable to assume the total number of cards is over 10,000 it is reasonable to assume the total number of cards is over 1000
