Answer:
7/40
Step-by-step explanation:
There are 3 girls+9 boys = 12 students in the 7th grade
P (girl in 7th grade) = girls/ total
= 3/12 = 1/4
There are 7 girls+3 boys = 10 students in the 8th grade
P (girl in 8th grade) = girls/ total
= 7/10
P(7th grade girl, 8th grade girl) = 1/4 * 7/10 = 7/40

Step-by-step explanation:
Answer:
a.) Domain: all numbers from 0 to 170 and d. Range: all numbers from 0 to 60
Step-by-step explanation:
The domain is all of the numbers that the graph is on, over the x-axis. Looking at the x-axis, the graph only spans across 0-170, so the answer would be a.) Domain: all numbers from 0 to 170.
The range is all of the numbers that the graph is on, over the y-axis. Looking at the y-axis, the graph only spans across 0-60, so the answer would be d. Range: all numbers from 0 to 60.
X + y + z = 54
y = x + 1
z = x + 2
x + x + 1 + x + 2 = 54
3x + 3 = 54
x + 1 = 18
x = 17
y = 17 + 1 = 18
z = 17 + 2 = 19
the three integers are 17, 18, and 19
Answer:
Step-by-step explanation:
hello :
factor the following polynomial is : (a+b+c) so :
3a(a+b+c)-2b(a+b+c)-c(a+b+c) = (a+b+c)(3a-2b-c)
