Mrs Atkins is going to choose two students from her class to take part in a competition.
1 answer:
Given:
Total number of girls in her class = 16
Total number of boys in her class = 14
To find:
The number of different ways of choosing one girl and one boy.
Solution:
We have,
Total number of girls = 16
Total number of boys = 14
So,
Total number of ways to select one girl from 16 girls = 16
Total number of ways to select one boy from 14 boys = 14
Now, number of different ways of choosing one girl and one boy is
Therefore, the required number of different ways is 224.

Step-by-step explanation:
The given rectangle TUVW has coordinates T(a, b), U (a + 2, b + 2), V ( a + 5, b - 1) and W (a + 3, b - 3).
Given that the coordinates of T and U are T (a, b), and U (a + 2, b + 2), we have;
The slope, m of the line TU is is found by the following relation;
Where we put (x₁, y₁) = (a, b) and (x₂, y₂) = (a + 2, b + 2), we have;
m = ((b + 2) - b)/((a + 2) - a) = 2/2 = 1
Whereby the slope of a line parallel to another line are equal, we have that the slope of the line parallel to the line that contains the side TU is also 1.
