y=-9
Answer:
56 times
Step-by-step explanation:
P(red & red) = 0.5×0.6 = 0.3
Expected no. = no. Of trials × p
No. of trials: 84/0.3 = 280
P(blue & blue) = 0.5×0.4 = 0.2
Expected no. = 280 × 0.2
= 56
Answer:
60 degrees
Step-by-step explanation:LARGE ANGLE...60-degrees
So, we have x + 2x = 90. Solving for x, we get x = 30. Since the first angle was called x, that means it's measurement is 30°. The second angle, 2x, is just twice the first angle, so its measurement is 60°
