P(5 on one throw) = 1/8
expected number of 5's in 400 throws = 1/8 * 400 = 50
Answer:
t = 7s + 4
Step-by-step explanation:
The goal is to get t alone. So we should move 7s to the other side of the equals to sign. When we move 7s to the other side of the equals to sign the sign changes to -7s. There are no like terms to be collected so the answer should be 7s + 4 for t.
I’m not gonna answer the entire thing for you but I’ll give you a Headstart. In problems like Number nine you take where the Second leg is an subtracted by the first leg giving you the degree measure. And problems like 18 through 21 you have to find angle measures with the same markings
Answer:
A and D
Step-by-step explanation:
We are given that
(3/4,2/3),(1/4,1),(1,1/2) and (1/2,1)
k=
Direct proportion:
Inverse proportion:
Therefore, it is not in direct proportion.
Therefore, 
Hence, the given points form an inverse variation .
