Answer:
{-2, 1}
Step-by-step explanation:
Make the fractions have a common denominator.
Now that both sides of the equation have a common denominator, you can cancel out the denominators.
Now, set the equation equal to zero and factor.
The y-values are {-2, 1}
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.
Answer:
Step-by-step explanation:
In order to round to the nearest thousandth, you must observe the digit to the right of the digit in the thousandth place and then:
In this case, given the number:
You can notice that the digit to the right of the digit in the thousandth place is 9.
Since , you must round up. Then:
Finally, to express this as a single-digit times a power of ten, move the decimal point three places to the right. Then you get:
