Answer:
20
Step-by-step explanation:
5 plus 7 plus 10 plus 3 = 25
25x4=100
5x4=20
20%
Another way
5/25 = 0.2
0.2 =20%
Answer:
a) we have the numbers 0, 2, 3, 5, 5. The mean and the median are both 3
b) we have the numbers 0, 0, 3, 5, 7. The mean and the median are both 3
In both cases the mean and the median are 3, but the mode differs. The mean and the median do not uniquely determine the mode.

Answer:
Blake's total number of cards now: 1.25b
Step-by-step explanation:
Total number of cards now would be equal to 25% increase from b.
<em>This means we INCREASE b by 25% OF b.</em>
<em />
What is 25% of b???
Now we need to ADD this to original amount, b.
So, 
Answer:
The measurement of angle a is 42.5°
The measurement of angle b is 19.5°
Step-by-step explanation:
Angle a = a
Angle b = b
m < a + m < b = 62°
"m <" means "measurement of angle..."
m < a + m < b = 4m < a - 108°
Subtract m < a from both sides of the equation
m < b = 4m < a - 108° - m < a
Simplify
m < b = 3m < a - 108°
Substitute into original equation
3m < a - 108° + m < a = 62°
Add m < a + 3m < a
4m < a - 108° = 62°
Add 108° to both sides of the equation
4m < a = 170°
Divide both sides of the equation by 4
m < a = 42.5°
m < b = 62° - 42.5° = 19.5°
Hope this helps :)
