Step-by-step explanation:
as you're surveying students randomly (well, every other student), you're not surveying students from sports teams, or people you know don't play any sports.
Answer:
A. 2/5
Step-by-step explanation:
3/5*2/4+2/5*1/4
6/20+2/20
8/20 = 2/5
X - 42 is a straight vertical line passing through -42 on the x-axis ( point -42,0)
so the slope is infinite .
Another line with same slope and parallel to it would be x = 36.
A horizontal like with slope 0 is perpendicular to it It would have equation y any number so y = 6 would be an example.
Answer:
x=-2 and y= 3
Step-by-step explanation:
First use x=2y-8 and put it in the other equation you will get:
-3(2y-8)+2y=12
Now distribute the -3 to whats inside the parenthesis:
-6y+24+2y=12
Combine like terms:
-4y+24=12
Subtract 24 from both sides:
-4y=36
Divide both sides by -4
Answer: 33, 37, 41, 45
Step-by-step explanation:
When n=1, we plug in to find a_1 = 33 + 4(1-1), or 33.
When n=2, we plug in to find a_2=33+4(2-1)= 37.
When n=3, we plug in to find a_3= 33 + 4(3-1) = 41
When n=4, we plug in to find a_4= 33 + 4 (4-1) = 45
