Choice B, a is equal to c and b is not equal to d
Answer:27/220
Step-by-step explanation:
She must have 2 �1 coins and 1 50p coin.
She can choose the 2 �1 coins 3C2 = 3 ways.
For each of those 3 ways she can choose the
50p coin 9C1 or 9 ways.
That's 3�9=27 ways to get �2.50.
She can choose any 3 coins in 12C3 = 220 ways.
The desired probability is 27 ways out of
220 ways,or 27/220, or 13.5% of the time.
One point on the line is (1,3) and another point is (9,11).
Find the slope of the two points on the line.

Now, let's make our equation in the form of y = mx + b, where m is the slope and b is the y-intercept.
We now have y = 1x + b
Plug in a point and solve for b.
y = 1x + b
3 = 1(1) + b
3 = 1 + b
b = 2
The equation is
y = x + 2.
If an angle doesn’t have two distinct factors, it isn’t prime.
