17. What expression is equivalent to log(200) - log (2)? Calculate the answer.
1 answer:
Answer: 2
Step-by-step explanation:
Recall from the laws of Logarithms:
Log a - Log b = Log ( a/b )
That means
Log 200 - Log 2 = Log ( 200/2)
= Log 100 , which could be written as
Log
Recall from laws of Logarithms:
Log = b Log a
Therefore:
Log = 2 Log 10
Also from law of Logarithm
Log 10 = 1
Therefore 2 Log 10 = 2 x 1
= 2

Answer:
The probabilities are 0.4 and 0.6 respectively.
Step-by-step explanation:
We are given two spinning wheels with numbers on it and we have to find the probability of getting 3.
In the first wheel, there are 5 slots and the numbers are 3, 3, 2, 5 and 4.
So the probability of getting 3 =
=
= 0.4
In the second spinner there are three 3's and total of 5 slots.
So probability of getting 3 =
=
= 0.6
Hence the probabilities are 0.4 and 0.6 respectively.
