It should be 161 but im not sure lol
Answer:
0.3125
Step-by-step explanation:
When a fair coin is tossed we find that
there are only two outcomes
Each toss is independent of the other
Hence if Xis no of heads then X is binomial with n = 5 and p = 0.5
Using binomial formula we can find probability for getting 3 heads exactly.
Required probability
= P(X=3)
= 
Answer:
It has reflectional symmetry with one line of semetry
Step-by-step explanation:
The line of semetry is through the middle of the figure
In y=kx , subst. -30 for x and 3 for y. Then solve the resulting equation for k:
3 = k(-30).
Dividing both sides by -30, we get:
-3/30 = -1/10 = k
The constant of proportionality is k = -1/10.
