Answer:
the answer is 300
Step-by-step explanation
there are 16 people so we divide that by the total number of students
400 divided by 16 = 25
since there are 12 right handed in each group we multpily it by 12
25 x 12 = 300
and theres your answer!
Answer:
A=z
B=-2
C=0
D=30
Step-by-step explanation:
First lets simply the equation
21 - (2x +3)2 + 4(1-1) + z^3
21 - (2x^2 + 9) + 4(0) + z ^3
21 - 2x^2 + 9 + z^3
- 2x^2 + z ^3 + 30
This means that:
A=z
B=-2
C=0
D=30
8/10= 0.8 tests per minute
If you are solving for x than the answer would be x=4.
