Answer:
1 is false
2 is true
3 is false
4 is false
Step-by-step explanation:
y-33=-2
y-33+32=-2+33
y=31
31=3x-2
31+2=3x-2+2
33=3x
33/3=3x/3
11=x
solution is (11,31)
graph of y=-3x-2... y=31 would be a horizontal line on 33 at the y axis
The equation to calculate how many ways that "r" things can be chosen from a larger set of "n" things is:n! / [r! * (n-r)!] =
12! / (5! * 7!) =
12 * 11 * 10 * 9 * 8 * 7! / (5! * 7!) =12 * 11 * 10 * 9 * 8 / 5 * 4 * 3 * 2 =11 * 9 * 8 =792 ways

Unlikely because 2 girls over 7 children is less then 50%
The answer is 523.6 and all you have to do is round it to the nearest hundredth
1.3 would be considered greater than negative 5. Although 1.3 is a decimal it is still a positive number and positives are worth more than negatives regardless
