Answer:
480
Step-by-step explanation:
The probability she will roll 2 odd numbers is 12/50 (the number of odd rolls over the total). This simplifies to 6/25
Multiply the probability times the total number of rolls to get a good estimate of the number of rolls that till be odd odd
6/25 * 2000 =480
where's the rest of question so I can help?
Answer:
Number of games won = 110
Step-by-step explanation:
Given:
Total games played = 154
The ratio of number of games won to number of games lost =
Solution:
Let the number of games won be =
Thus, number of games lost =
The total games played can be given as =
Thus, we have:
Dividing both sides by 7.
∴
So, number of games won =
<span>f(x)=f(x−1)+2 this is one example =)</span>
So basically you use the ratio they have given you. You either multiply by 2 if image is enlarged or divide by 2 if it is reduced. (Keep in mind I got the 2 from your ratio : 1inch : 2inches) Therefore the find the original width, you multiply 10 by 2, giving you 20 inches.
