For the selection to be 10, there has to be at least 3 girls. So there's a 1/4 chance of 3 girls picked, 1/4 4 girls, 1/4 5 girls and 1/4 6 girls. Because the sum of people has to be 10, if 4 girls are picked, to make 10 people there is a 1/1 chance of 6 boys. 1/4 * 1/1 = 1/4. So 1/4 chance of 4 girls and 6 boys
It would be two places to the right of 0 because -3+5=2
Answer is (1 9/20) because 1 and 45/ 100 can be simplified by divided 45/100 by 5. 45 divided by 5 is 9 and 100 divided by 5 is 20. A mixed number is a combination of a whole number and a fraction. The whole number is 1 and the fraction is reduced to 9/20.
4:3 > 8:6 > 12:9 > 16:12 > 20:15 > 24:18 the answer must be 24 seventh graders are there
