Answer:
144 students are expected to be left handed
Step-by-step explanation:
Approximately 12% of the population is left-handed. This is not the exact number of left handed students but it is very close to it. It could be above or below the exact amount, hence the word, approximately was used.
In terms of probability, the probability of a student being left handed is 12/100 = 0.12. The probability of a student being right handed is 1 - 0.12 = 0.88. Therefore,
The expected number of left handed students is the probable number of left handed students and it is
0.12 x total number of students
= 0.12 × 1200 = 144 students

50 honestly have no clue sorry
The simplified answer is: -28a - 13b
Answer:
D
Step-by-step explanation:
To solve this, we need to use the corresponding angles theorem. It states that when a transversal line cuts across 2 parallel lines, then the corresponding angles there-in are congruent or equal.
Now the pair of corresponding angles we have in this question are as follows;
1 and 5
3 and 7
2 and 6
4 and 8
All these pairs are congruent corresponding angles.
Looking at the options, option D is correct
