Answer:
If they are both red, 7/22
If both blue, 1/22
Yellow, 1/66
Step-by-step explanation:
7/12 times 6/11 (both decrease by one because there is no replacement)
3/12 times 2/11
2/12 times 1/11
Is that negative 2 minus 8? if so put that into the calculator and add 8 to both sides and divide by 2 after that. simple algebra
Answer:
1/5
Step-by-step explanation:
Note that this graph goes through (0, 0) and (2/5, 1/2).
Thus, the slope of the graph is m = rise / run = (1/2)/(2/5) = 1/5.
This m = 1/5 is ALSO the constant of proportionality.
Answer:
1.B 2.H 3. A
Step-by-step explanation:
1. First, find out the percentage of people who voted for Mathematika in survey one.
The total amount of people who voted is 14+17+19, which equals 50. 17/50 people voted for Mathematika, 17/50 = 0.34.
To find out how many people out of 300 will vote for Mathematika, multiply the 0.34 by 300. 300 x 0.34 = 102, so 102 people will vote for Mathetika.
2. You use the same logic for number 2. 14+17+19+20+19+11 = 100, so 100 people voted in total. 34 people voted for Infinitus. 34/100 = 0.34. Multiply 0.34 by 750 to get 255 people will vote for Infinitus.
3. The mean = the average. To find the average, add up all of the numbers, then divide that number by the amount of numbers added together.
7+9+11+13+15 = 55
5 numbers were added together so you divide 55 by 5
55/5 = 11. The mean is 11
9+10+11+12+13 = 55
There were 5 numbers added together
55/5 = 11. Both the means were the same
