Please Help! I'm stuck!

Mathematics
1 answer:
atroni [7]3 years ago
8 0

Answer:

See attached image

Step-by-step explanation:

If you have two marbles in a bag and you are choosing the marbles randomly twice, then we can look at fractions.

Each time, you have a 0.5 chance of picking the silver marble. After you pick that, you have another 0.5 chance of picking the silver marble again.

This applies with any combination.

This means that the probability of you getting two silvers in a row is 0.25.

Since the marbles are the same size and nothing is stopping you from choosing one, this probability applies to all combinations possible.

Hope this helped!

Can somebody anybody please help me with this math problem?
Annette [7]

Answer:

30°

Step-by-step explanation:

Angle C = 55°, Angle D = Angle A = 65°, Angle B = 2x

Sum of angles in a triangle = 180°

65° + 55° + 2x = 180

120 + 2x = 180

2x = 180 - 120

2x = 60

x = 30°
