You would divide miles to hours amd get 57.5
        
                    
             
        
        
        
Answer: THE ANSWER IS 2 :)
Step-by-step explanation:
3(q+2)  Do distributive property
3q=6 Divide 3q to both side 
3q = 3q
q= 2       This is the answer 
 
        
             
        
        
        
C. Wich mean she worked 5 hours and half an hour (0.5)
        
                    
             
        
        
        
Answer:
190
Step-by-step explanation:
Data provided in the question:
Confidence level = 99%
Therefore,
α = 1% = 0.01
[ from standard normal table ]
z-value for  = 2.58
 = 2.58 
Margin of error, E = $0.06
Standard deviation, σ = $0.32
Now,
n = 
Here,
n is the sample size (or the minimum number of gas stations  )
on substituting the respective values, we get
=  
 
=  
 
= 13.76²
= 189.3376 ≈ 190
Hence,
minimum number of gas stations that she should include in her sample is 190
 
        
             
        
        
        
Answer:
The interval notation for the domain is ![[\frac{23}{3},\infty  ]](https://tex.z-dn.net/?f=%5B%5Cfrac%7B23%7D%7B3%7D%2C%5Cinfty%20%20%5D) .
.
Step-by-step explanation:
Consider the provided information.
It is given that 
We need to find the value of  .
.
Put the value of g(x) in   .
.
 ....(1)
  ....(1)
Now, put x=x-7 in 



From equation 1.

The domain of the function is the set of input values for which a function is defined.
Here, the value of  should be greater or equal to 0 as the square root of a negative number is not real.
 should be greater or equal to 0 as the square root of a negative number is not real.
Domain= 
 
 
The value of x is all real number greater than  .
.
Hence, the interval notation for the domain is ![[\frac{23}{3},\infty  ]](https://tex.z-dn.net/?f=%5B%5Cfrac%7B23%7D%7B3%7D%2C%5Cinfty%20%20%5D) .
