Answer:
Step-by-step explanation:
Difference in the distance = 50 yards
Difference in speed = 8 - 6 = 2 y/s
<u>Time to  cover the gap is:</u>
<u>Sandra will run the distance:</u>
 
        
                    
             
        
        
        
A is the correct choice. 
This is based on the vertical line test. If you were to draw an imaginary vertical line on the graph, it would only intersect the graph at one point, which proves that all x values are different (a function).
        
                    
             
        
        
        
Answer:
Category                         Relative Frequency
male survivors                           17.3%
males who died                          63.7 %
Female survivors                        15.1 %
Females who died                       3.8%
Step-by-step explanation:
- The relative frequency is the proportion of the number of times the event occurs to the total number of trials.
Given : Total people on ship = 2274
Number of male survivors = 394
⇒ Relative Frequency of male survivors =
In percent , 
Number of males who died =1449
⇒ Relative Frequency of male who died =
In percent , 
Number of female survivors =344
⇒ Relative Frequency of female survivors =
In percent , 
Number of females who died = 87
⇒ Relative Frequency of females who died =
In percent , 
Hence, the complete table would be :
Category                         Relative Frequency
male survivors                           17.3%
males who died                          63.7 %
Female survivors                        15.1 %
Females who died                       3.8%
 
        
             
        
        
        
Answer:
x = 7.2 
Step-by-step explanation:
Let x be a positive number such that the distance between x and -3.8 on a number line is exactly 2 times the distance between x and 1.7.
Now. the distance between - 3.8 and x will be (x + 3.8) and the distance between x and 1.7 will be (x - 1.7) {Since x is a positive number}
(Assuming x is greater than 1.7}
Given that, x + 3.8 = 2(x - 1.7)
⇒ x + 3.8 = 2x - 3.4
⇒ x = 7.2 (Answer)
