Lara makes the following statement: "there is an 80% chance of rain tomorrow and a 10% chance i will go to the park." what is the chance that it will rain tomorrow and lara will go to the park? 90% 70% 8% 6% at a conference for 250 people, 40% of the participants are french, 45% are americans, 10% are germans, and the rest are of other nationalities. how many french participants are at the conference? 150 130 120 100

answer: c

(2, -4)

goes 7 to the

(9, 4)

easy

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
