Answer:
She can run 58.5 yards in 9 seconds.
Step-by-step explanation:
39/6=x/9
cross product
6*x=39*9
6x=351
x=351/6
x=58.5
 
        
             
        
        
        
The answer should be f(x)=9x + 60
        
             
        
        
        
Answer:
Todd's Z-score is - 0.27    
Step-by-step explanation:
<u><em>Explanation</em></u>:-
<u><em>Step(i)</em></u>:-
Given data A test is normally distributed with a mean of 70 and a standard deviation of 10. 
<em>Mean of the population 'μ' = 70 </em>
<em>Standard deviation of the Population ' σ ' = 10</em>
<em>let 'x' be the random variable in normally distributed</em>
<u><em>Step(ii)</em></u>:-
<em>Given raw score  'x' = 55</em>
Todd's Z-score 
                       
                      
                      Z = -0.27
<u><em>Final answer</em></u>:-
<em>Todd's Z-score is - 0.27        </em>            
 
        
             
        
        
        
The first step to solving this is to multiply both sides of the equation by 15.
9x - 5x = 15x - 15
Collect all of the like terms on the left side of the equals sign.
4x = 15x - 15
Move the variable to the left side of the equation and change its sign.
4x - 15x = -15
Now collect the like terms on the left side of the equation for the second time.
-11x = -15
Lastly,, divide both sides of the equation by -11 to get your final answer.

This means that the correct answer to your question is 

,, or 1
