You can use right triangles and congruence. So if the distance from Home to First is x, then the distance from Home to Third is also x because the two triangles are congruent.
5y=4x+10 /:5
y=4/5 x+2
y=mx+k
m₁*m₂=-1
4/5 *m=-1
m=-5/4
y=-5/4 x+k
-5/4*(-15)+k=8
75/4 + k=8
k=32/4 - 75/4
k=-53/4=-13.25
y=-5/4 x - 53/4
Answer:
7/15 is the probability of selecting a boy and a girl.
Step-by-step explanation:
Combination = nCr = n!/((n-r)!r!)
((7C1)(3C1))/(10C2)
= (7*3)/45
=21/45 = 7/15 the probability of selecting a boy and a girl.
