Answer: The probability of the player getting a hit is 0.214.
Step-by-step explanation:
Since we have given that 
Probability  that a baseball player gets a hit if the weather is good = 40% = 0.4
Probability that a baseball player gets a hit if the weather is not good = 20% = 0.2
Probability of good weather = 7% = 0.07
Probability of not good weather = 100-7 = 93% = 0.93
According to question, the probability of the player getting hit is given by

Hence, the probability of the player getting a hit is 0.214.
 
        
             
        
        
        
Answer:
25 necklaces
Step-by-step explanation:
each necklace brings $16 profit (20-4=16)
400÷ 16= 25
so, at 25 necklaces, there will be enough profit to break even after paying for the advertising.

The logarithm written as a sum of logarithm and simplified as much as possible is 
<h3>Simplifying Logarithms</h3>
From the question, we are to write the given logarithm expression as a sum or difference of logarithms
The given logarithm is 

This can be written as 

From one of the rules of logarithm, we have that 

Thus, 
 becomes
  becomes

This can be further simplified into


If desired, this can be further simplified into




Hence, the logarithm written as a sum of logarithm and simplified as much as possible is
