Answer:
b) 33
Step-by-step explanation:
You reverse the process of finding the second average, 21, which will help you find the original average, 25. First you multiply the second average, 21, to retrace your steps. We do this because the last thing we do when we find the average is divide. when you multiply 21 you get 42. Now you have the value of the first two numbers. Then you experiment with the numbers. To save time I'll get to the point. When you add 33 + 42 you get 75. Then you divide by 3 to get 25. You divide by three because the instructions say there was 3 numbers to start with. Hope this helps.

Answer:
q = 40
Step-by-step explanation:
When the quadratic has roots p and r, it can be factored as ...
(x -p)(x -r) = x² -(p+r)x +pr
So, the sum of the roots is 14, and their difference is 6. This lets us find the roots from ...
p + r = 14
p - r = 6
2p = 20 . . . add the two equations
p = 10
r = 14 -p = 4
The value of interest is then ...
q = pr = (10)(4)
q = 40
__
The graph shows the roots to be 4 and 10, as we found.

Answer:
0.03
Step-by-step explanation:
Percentage of americans with diabetes = 10.5% = 0.105
Percentage of americans without diabetes = 89.5% = 0.895
Adults over 40 with diabetes tested positive = 95% = 0.95
Adults over 40 with diabetes tested negative = 5% = 0.05
Adults over 40 without diabetes tested positive = 3.5% = 0.035
Adults over 40 without diabetes tested negative = 96.5% = 0.965
The probability of selecting an adult over 40 without diabetes but positive diagnosis;
= 0.895 * 0.035
= 0.031325
= 0.03
