2. Tiago works with electronics as a hobby. One supplier has very low cost circuit components but a relatively
high defect rate. Suppose the defect rate from this supplier is 10, and that each defect is independent.
a. If Tiago buys 320 items from this supplier, how many should he expect to be defective?
vill
b. What is a typical deviation from the expected amount in part (a)?

answer: i guess 105 degrees?

step-by-step explanation:

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour

7/2

(decimal: 3.5)

welcome ; )

step-by-step explanation:

both the histogram and the stem and leaf plot will visually show how many shoppers were of various ages within each range of data.   the histogram does not give us the specific ages of these shoppers unlike the stem and leaf plot.a histogram does not give us a true range of the data because we do not know exactly how old the shoppers were. a stem and leaf plot will give exact ages, so we can determine the exact range along with all measures of center and the others measures of center.   with the histogram, we cannot find any of these.
