The probability of rolling a number less than 3 on a number cube is 2/6 . Jennifer rolls a number cube 60 times. How many times should Jennifer expect to roll a number less than 3

20 times

Step-by-step explanation:

2/6

she rolls it 60 times so it turns into

2/6 = x/60

60*2 = 120

60/120 = 20

so

2/6 = 20/60

definitely a. the others have almost all data points on one side of the line.

step-by-step explanation:

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
