A class of ninth-grade students is asked to purchase some classroom supplies. Each student will contribute 4 pencils to the class. The teacher already has 10
pencils. Use this information to answer the following questions,
(a) Write down an arithmetic sequence that describes the total number of
pencils in the classroom after each student brings their pencils to school.
Write at least 5 terms.
(b) How many pencils will be in the classroom when 5 students bring in their
pencils?
(c) When the supply is full, there will be 98 pencils. How many students are
in the class? Use both a geometric and algebraic approach to answer this
question

(co 3) the times that customers spend in a book store are normally distributed with a mean of 39.5 minutes and a standard deviation of 9.4 minutes. a random sample of 25 customers has a mean of 36.1 minutes or less. would this outcome be considered unusual, so that the store should reconsider its displays? no, the probability of this outcome at 0.035, would be considered usual, so there is no problem yes, the probability of this outcome at 0.035, would be considered unusual, so the display should be redone no the probability of this outcome at 0.359 would be considered usual, so there is no problem yes, the probability of this outcome at 0.965 would be considered unusual, so the display should be redone
