Answer:
-3/2+√29/2 or -3/2-√29/2
Step-by-step explanation:
When the graph intercepts with x-axis, the value of y is zero.
So substitute y with zero.
Angle B is the linear pairs with 60°, so the size is 180-60=120°
Angle ABC is the linear pair with 120°, so the size is 180-120-60°
Angle A corresponds to angle 60°, so they are equal
Angle BAC is the linear pair with angle A and angle 70°, so 180-(60+70)=50°
Angle ACB is 180-(50+60) = 70°
Answer:
D. 12/27
Step-by-step explanation:
Ratios are just like fractions
12 ÷ 3 = 4
27 ÷ 3 = 9
4/9 is 12/27 simplified by 3

Answer:
125
Step-by-step explanation:
To find the expected number of black marbles, take the probability of getting a black marble times the number of marbles drawn
P(black) * 200
5/8 *200
125
We should expect 125 black marbles
