Hannah works two shifts a week at a coffee shop, one on a weekday and one on the weekend. She is available during the week from Tuesday to Thursday and on both days on the weekend. Her boss randomly chooses which shifts Hannah will work.

a) Does choosing the two shifts for one week involve dependent or independent events? Explain.

b) Determine the probability that Hannah will work on Tuesday and Saturday

x = -2

y = 848

step-by-step explanation:

plug in the numbers

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true
