AB=h can be found with
tan 60° =AB / AC, and AB=h= tan60° x AC
h= 14* 1.73=24.24
If 100% is 8590$
Than 1% is 85.9$
3% is then 257.7$
1-When you have a the logarithm given in the problem above, you can solve it by using the correct properties for logaritms.
2- The students could solve it as below:
<span>log4(2x-12)=3
4^[</span> log4(2x-12)]=4^3
3- By definition a^log(x)=x, therefore,
2x-12=4^3
2x-12=64
4- Now, the students can solve for x:
x=38
The first step is incorrect, because the term on the right member must be 4^3.
Answer: B. 0.4772
Step-by-step explanation:
Given : The mean time : 
Standard deviation : 
Let X be the service time of a randomly selected customer.
Assuming a normal distribution, the value of z-score is given by :-
For x = 64
For x = 100
The p-value =
Hence, the probability that a randomly chosen customer experiences service done between 64 and 100 minutes = 0.4772
