55/8 or 55:8 will be the unit rate I think
<1 and <8 are alternate exterior angles
Hope it helps

Answer:</h2><h2>The theoretical probability of four students from your school being selected as contestants out of 8 possible contestants spots =

</h2>
Step-by-step explanation:
The number of students participated = 30
Total audience = 150
By probability , to find the solution =
where n(E) is the number of favorable outcomes,
n(S) is the number of total outcomes.
n(S) is the number of ways any 8 students can by picked from the audience= 
n(E) is the probability of picking four students from our school and five students from another school.
n(E) =
= 
=
= 
Answer:
y = x-2
Step-by-step explanation:
Because y is always 2 less than x the second equation is correct.
5 = 7-2
6 = 8-2
And so on.
Answer:
b) 1 / 4
c) -3
Step-by-step explanation:
b) line passing through points (0,-1) (4,0)
slope = (y2 - y1) / (x2 - x1)
= (0 - (-1) ) / (4 - 0)
= 1 / 4
c) line passing through points (-1,2) (0, -1)
slope = (y2 - y1) / (x2 - x1)
= (-1 - 2) / (0 - (-1) )
= -3 / 1
= -3
