A bag contains six red and ten black marbles if you pick a marble from the bag what is the probability that the marble will be b
lack.If you pick a marble record it’s color and return it to the back 200 times how many times can you expect to pick a black marble
1 answer:
Answer:
125
Step-by-step explanation:
The total number of marbles is 6+10 = 16
P (black) = black / total
= 10/16 = 5/8
With 200 draws, take the probability of P(black) times 200 since the marble is returned each time
200 * (5/8) = 125
We would expect to get 125 black marbles

Answer:
f = 2
Step-by-step explanation:
0.3 = 0.5f - 0.7
1.0 = 0.5f
2 = f
Check:
0.3 = 0.5(2) - 0.7
0.3 = 1 - 0.7
0.3 = 0.3

Answer:
Either of the following square values:
![8^{2} =64 \,\,in^2\\15^2= 225\,\,in^2\\17^2=280\,\,in^2](https://tex.z-dn.net/?f=8%5E%7B2%7D%20%3D64%20%5C%2C%5C%2Cin%5E2%5C%5C15%5E2%3D%20225%5C%2C%5C%2Cin%5E2%5C%5C17%5E2%3D280%5C%2C%5C%2Cin%5E2)
Step-by-step explanation:
The three possible answers correspond to the square of the sides of the triangles via the Pythagorean theorem. And these are:
![8^{2} =64 \,\,in^2\\15^2= 225\,\,in^2\\17^2=280\,\,in^2](https://tex.z-dn.net/?f=8%5E%7B2%7D%20%3D64%20%5C%2C%5C%2Cin%5E2%5C%5C15%5E2%3D%20225%5C%2C%5C%2Cin%5E2%5C%5C17%5E2%3D280%5C%2C%5C%2Cin%5E2)
