Answer: room 101 and room 107
Step-by-step explanation:
In room 101, the ratio of boys to girls is 16:12. This is further simplified to its lowest fraction by dividing by 4. It becomes 4:3
In room 104, the ratio of boys to girls is 20:9. This cannot be further simplified to its lowest fraction.
In room 107, the ratio of boys to girls is 12:9. This is further simplified to its lowest fraction by dividing by 3. It becomes 4:3
Therefore, room 101 and room 107 have the same ratio.
Answer:
56 different tests
Step-by-step explanation:
Given:
Number of wires available (n) = 8
Number of wires taken at a time for testing (r) = 5
In order to find the number of different tests required for every possible pairing of five wires, we need to find the combination rather than their permutation as order of wires doesn't disturb the testing.
So, finding the combination of 5 pairs of wires from a total of 8 wires is given as:

Plug in the given values and solve. This gives,

Therefore, 56 different tests are required for every possible pairing of five wires.
Answer:
3, -6, 0, -9, 6
Step-by-step explanation:
Select the numbers below that are part of the domain of the function. (3, 0); (-6, -5); (0,-3) ; (-9, 7) ; (6, 4
The domains are independent variables in Mathematical equations. They are the variables that determine the range of any Mathematical equations.
From the series of numbers given above, the domains are:
3, -6, 0, -9, 6
5×3=15 so 15÷ 3=5, The answer to this question would be is 5.
Answer:
y=3/10x
Step-by-step explanation:
First, use the formula y2-y1/x2-x1. Pick any two points from the line to put into this formula. In this case, I would pick (0,0) and (20,6) cause I'm lazy lol. Plot these points into the formula. It would look like this 6-0/20-0. Simplify this to get 6/20. The GCM of 6 and 20 is 2 so divide 2 in each side to get 3/10. Because the y-intercept is on 0, there is no y-intercept. Therefore, the equation is y=3/10x
