Step-by-step explanation:
Answer. The probability of picking a blue marble from the blue urn is 2/6=1/3. The probability of picking a blue marble from the black urn is 11/15. The two events are independent so the probability of a blue marble from each urn is the product of the two separate probabilities=1/3×11/15=11/45.
Im not sure but its most likely 29a/20 because you cant simplify any more than what it already is because of the numbers that your dealing with so if your asking why its not able to be simplified its that reason plus there is a "a" in the fraction as well.
Answer:
<u>257/16</u>
Step-by-step explanation:
Given :
Then :
- x² + 1/x²
- (x¹)² + 1/(x¹)²
- (4)² + 1/(4)²
- 16 + 1/16
- <u>257/16</u>
Answer:
73,205 vinyls
Step-by-step explanation:
To calculate the number of vinyls sold we need to calculate the compounded increase. To do this we simply raise the number of times that the initial value increases by the number of difference in years from the start to the current year. Then we multiply this number by the initial number of vinyl records. Since there are 4 years between 2012 and 2016, the formula would be the following...
50,000 * = x
50,000 * 1.4641 = x
73,205 = x
Finally, we can see that there will be a total of 73,205 vinyls in 2016
First one answer is C.
