Answer:
1. 68/89
2. 46/267
Step-by-step explanation:
1. The total number of people in drama or athletics can be found by adding up all categories where a person fits at least one of the criteria:
51+11+12+15+108+7=204
Now we need to add up the total number of people in all categories:
51+11+12+15+108+7+63=267
Finally, we divide the total number of people in either drama or athletics by the total number of people in all categories:
204/267 = 68/89
2. The total number of people in athletics and drama can be found by adding up all categories where a person fits both criteria:
15+12=27
The total number of people in music and athletics can be found by adding up all categories where a person fits both criteria:
7+12=19
Now, we add both of these numbers together and put it all over the total number of people:
27+19=46
46/267
Answer:
22.84, 5.83
Step-by-step explanation:
Pythagoras theorem states that: a^2+b^2=c^2
So, for red triangle, it will be: 9^2+21^2=b^2
81+441=b^2
522=b^2
square root of 522=b
22.84=b
For purple one,
3^2+5^2=a^2
9+25=a^2
34=a^2
square root of 34=a
5.83=a
Its telling you how many marbles there are and the coler that be used on 9-11 ,its asking you to find the outcome same with 10,now 11 describe the scoring and how its a fair game if you need aswere let me know and i help with them

= 12-5/3-2
= 7/1
= 7
