This is simple. Coordinate form is (x,y) so you would just plug in your values.
2(5)-(1)=11
10-1 does not equal 11, so no it is not a solution.
Answer:
x = 4
Step-by-step explanation:
Answer:
0.5
Step-by-step explanation:
Let D be the event of selecting a marble with dots.
Let P be the event of selecting a purple marble.
The probability of selecting a marble with dots, P(D)=0.2
The probability of selecting a marble that is both purple and has dots,
We want to determine the probability of selecting a purple marble given that the marble has dots on it, P(P|D)
By the definition of conditional probability:
The probability of selecting a purple marble given that the marble has dots on it is 0.5.
Answer:
Therefore both Ken and Billy ran the same amount of the training course.
Step-by-step explanation:

iv) Ken finished of his run Therefore Billy finished only of the training course.
v) Therefore both Ken and Billy ran the same amount of the training course.
Interior angles of a triangle add up to 180
< X + < Y + < Z = 180
68 + Y + 90 = 180
158 + Y = 180
Y = 180 - 158
Y = 22 <==
