Answer:
Step-by-step explanation:
In general, 
Substitute x = 2, y = 15
(1) 
<u />
Substitute x = 1, y = 5
(2) 
Divide equation (1) by equation (2)
3 = b
Now substitute b = 3 in equation (2) to find k
5 = k(3)
Since we know the values for k and b, we now have the exponential function that passes thru (1, 5) and (2, 15)

Answer:
Step-by-step explanation:
9/16=x/12
cross product
16x=9*12
16x=108
x=108/16
simplify
x=27/4
---------------
x-3/18=12/9
x=12/9+3/18
x=24/18+3/18
x=27/18
x=3/2
--------------------
7/11=18/x+1
18/x=7/11-1
18/x=7/11-11/11
18/x=-4/11
x=18/(-4/11)=(18/1)(-11/4)=-198/4=-99/2
x=-99/2

Her statement is not reasonable because it is not true that 25% of female marathoners run 13 or more miles a week, it is true that 25% run less than 13 miles a week (out of the data). The rest of the data would be 75%, making the statement, "75% of female marathoners run 13 or more miles a week" true. The way she recorded the data does not interfere with the statement being reasonable since it is unbiased.
