Answer:
Step-by-step explanation:
Probability of an event occurring is the ratio of the number of time the event occur over the total sample space
Total sample space is 504 ways
Now, the event that you win the first prize and your mum wins the second price, can only occur in one way, their is no other way it can occur
Therefore,
Pr(you win first prize and your mom wins second prize) = 1 / 504
So, the correct answer is C.

Answer:
Step-by-step explanation:
a) if the number of drill sold is plotted on the horizontal or x axis and the price of each drill sold is plotted on the vertical or y axis, the slope would be
m = (y2 - y1)/(x2 - x1)
= (40 - 50)/(3000 - 2000)
Slope, m = - 0.01
b)For every additional drill sold, the price per drill decreases by 0.01 cent
c) The equation of a straight line modelled in the slope intercept form is expressed as
y = mx + c
Where
m represents slope
c represents the y intercept
To determine the y intercept, we would substitute m = - 0.01, x = 2000, y = 50 into y = mx + c. It becomes
50 = - 0.01 × 2000 + c
50 = - 20 + c
c = 50 + 20 = 70
The equation modelling the situation is
y = - 0.01x + 70
Therefore, if the trend continues, the number of drills that would be sold for $43 is
43 = - 0.01x + 70
0.01x = 70 - 43 = 27
x = 27/0.01
x = 2700
2700 drills would be sold

Answer:
Step-by-step explanation:
Before subtracting we require the fractions to have a common denominator.
The lowest common multiple of x + 4 and x + 6 is (x + 4)(x + 6)
Multiply the numerator/denominator of the first fraction by x + 6 and
multiply the numerator/denominator of the second fraction by x + 4
= 
- 
Expand the numerators and simplify leaving the denominator
