The box has 2 blue balls, 5 red balls and n yellow balls. Now, you draw a ball from the box. You get 2000 dollors if you draw blue ball, 1000 dollors if you draw red ball, and 0 dollors if you draw yellow ball. If the expect value of draw a ball is 600 dollors, what is the value of n? (A)8 (B)9 (C)10 (D)11 (E)12​

i think the correct option is the second option.

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh

its a, i had the same answer, its from study island right

step-by-step explanation:

236 cm 16 time 12 = 192

6 times 7 = 42

192+42
