Answer:
100 children
Step-by-step explanation:
The sum of angles of a triangle equals the straight angle (180°), therefore:
3x + 12x + 1 + 16x - 7 = 180
31x-6=180
31x = 180 + 6
31x = 186
x = 186/31
x = 6
Then, the angles are:
3(6) = 18°
16*6 - 7 = 89°
12(6) +1 = 73°
Answer:
Zero.
Step-by-step explanation:
The empirical (or experimental ) probability is that calculated from the result of the trial.
There were no 5's thrown so the empirical probability of a 5 coming up is 0/50 or 0.
