Answer: 1)100ways and 2)90ways
Step-by-step explanation:
Given :-The 10 students who completed a special flying course are waiting to see if they will be awarded the one Distinction or the one Merit award for their efforts.
Ways can the two awards be given if the same student can receive both awards (i.e repetition is allowed)
=10×10=100ways
Ways can the two awards be given if the same student cannot receive both awards(i.e. repetition is not allowed)
=10×9=90ways

Answer:
Gradient of the line with points (-4,1)&(3,-2) is
(-2-1)÷(3-(-4))=-3/7
Then the equation of that^ line is
Y-1=-3/7(x-(-4))--->y=-3/7x-5/7
Since this^ line is perpendicular to the line you are looking for.the gradient of the line you are looking for is -1÷(-3/7)=7/3
The equation of the line you are looking for is
Y-1=7/3(x-2)--->y=7/3x-11/3
[Cause the line you are looking for passes through the point (2,1) and you found the gradient of this line]
Answer:
600ft square
Step-by-step explanation:
Lets multiply all numbers given by 10 beacuse they represent 10 ft
20ft*30ft=600ft square` the area of living room
25ft*20ft=500ft square` the area of bedroom
