From the given ordered pair representing Jacinda's progress, her speed is equal to 10 miles per hour. Letting x be the time it takes for Jacinda to catch up with Raj, the total distance Raj would travel is 
                            1.5 + 4.5x
and Jacinda's total distance is 10x. Mathematically,
                                1.5 + 4.5x = 10x 
The value of x from the equation is 0.27 hours. Therefore, Jacinda needs to run 2.7 miles to catch up with Raj.

Answer:
Step-by-step explanation:
Z score is the number of standard devations above the mean.
For example if z=1, the data value is 1 st. dev. above the mean.
So, z=1.95, so the player's heigh is 1.95 st. dev. above the mean.
 
        
             
        
        
        
Answer:
Average rate of change = 2
Step-by-step explanation:
We need to find the average rate of change of f(x) over the interval [-4,-1], so first we need to find the end points at x=-4 and x=-1.
From graph we see that y=-3 when x=-4, So the point is (-4,-3)
From graph we see that y=3 when x=-1, So the point is (-1,3)
Now we can plug these points into average rate of change formula:

where (a,f(a)) and (b,f(b)) are the given points.




Hence final answer is 2.
