Answer:
i think ur right but i dont know for sure i did the math and got that
Step-by-step explanation:
The answer is B, trust im a math teacher :p
F(x)=2^x
Lets say f(x) is y
Y=2^x
Take log both side
Log(y)=log(2^x)
Logy=log2^256
logy=256×log2
By Log property
Logy=77.06
Answer:
Yes, it is a valid random sample for if I were to randomly survey 50 people from the phone books of 20 randomly chosen cities.
Step-by-step explanation:
Because a random sample, means, the following: a subset of a statistical population in which each member of the subset has an equal probability of being chosen. And the randomly survey 50 people from the phone books of 20 randomly chosen cities matches this meaning.
Add up the distances he has walked so far.
3/8 + 1/8 = 4/8
1 is the same thing as 8/8. So subtract the distance he has walked from 8/8.
8/8 - 4/8 = 4/8 miles or 0.5 miles
