Answer:
we got 80% from 20 questions
then
(20/100)×80=16
so he answered 16 questions correctly
Answer:
-1
Step-by-step explanation:
-3-8+12+9-15 divided by 5
gives -5/5=5
mean means average total number over frequency
Answer:
185
Step-by-step explanation:
All you have to do is multiply 200 by 92.5/100 (because it is 92.5%). This gives you 185.
Hope this helps!

Answer:
1. 
2. 
3. Domain: 0≤x≤7
Range: 0≤y≤12
Step-by-step explanation:
1. Assuming 1 unit = 1 box on the grid, therefore, coordinates of C and D would be:
C(0, 0),
D(7, 12)

2. Equation of the using the slope-intercept formula,
, where,

b = y-intercept, which is where the line CD cuts the y-axis = 0
Plug in the values for m and b into the formula to get the equation of the line:


3. The domain for C to D part = all x-values = 0≤x≤7
The range = all y-values = 0≤y≤12
