7th grade has 3 boy out of 10 students
probability of picking a boy is 3/10
8th grade has 9 boys out of 12 students are boys
probability of picking a boy is 9/12 reduced to 3/4
3/10 x 3/4 = 9/40 probability of picking 2 boys
Answer:
Evaluate the function.

Step-by-step explanation:
M=y2-y1/x2-x1
m=12-4/-6--2
m=8/-4
m=-2
6-(1/9)+1x8
=6-(1/9)+8
=6/1-1/9+8/1 (change 6 and 8 to fractions)
=6/9-1/9+8/1
=54/9-1/9+8/1
=53/9+8/1
=53/9+8/9
=53/9+72/9
=125/9
Answer:
Below in bold.
Step-by-step explanation:
The 3 angles add up to 180 degrees as they are in a triangle.
So 10x - 33 + 4x - 19 + 100 - 2x = 180
12x = 180 + 33 + 19 - 100
12x = 132
x = 11.
So the 3 angles are
10(11) - 33 = 110 - 33 = 77 degrees
4(11) - 19 = 25 degrees
100 - 2(11) = 78 degrees
