Answer:
There is a constant rate of change of both money raised and distance, so the function is linear. But the variables do have a proportional relationship, and the graph includes the point (0, 0)—0 dollars will be raised by a person who runs 0 miles. So this is a proportional function.

Answer:
15.87%
Step-by-step explanation:
First thing here is that we calculate the z-score which corresponds to 76
mathematically;
z-score = (x-mean)/SD 
mean = 71 and SD = 5
plugging these values, we have;
z = (76-71)/5 = 5/5 = 1
Now, we want to firstly get the probability that we have a student shorter than 76 inches 
The probability we want to calculate is P(z<1)
we can get this using the z-score table directly 
That would be 0.15866
In percentage that is 15.866% which is 15.87% to the nearest tenth
 
        
             
        
        
        
It decline 2 million dogs. 2 million over 72 million = 1/36, which is approximately 2.8 percent.
