Answer:
Step-by-step explanation:
<u>Three faces are equal triangles with:</u>
- base = 8 units, height = 6 ft
<u>The base is a triangle with:</u>
- base = 8 ft, height = 6.9 ft
<u>Surface area is sum of areas of 4 faces:</u>
- S = 3*(1/2*8*6) + 1/2*8*6.9 = 99.6 ft²

Answer:
30% probability that the ball taken from B is red.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question:
Red ball from urn A:
3/6 = 1/2 probability of getting a red ball from urn A.
Then urn B will have 5 balls, 2 of which are red, so 2/5 probability of getting a red ball.
Blue ball from urn A:
3/6 = 1/2 probability of getting a blue ball from urn A.
Then urn B will have 5 balls, 1 of which is red, so 1/5 probability of getting a red ball.
Total:

3/10 = 0.3 = 30%.
30% probability that the ball taken from B is red.
It does show a function because it passes the vertical line test (no two points have the same x value).
