Answer:
(a) 3 (b) 1/3
Step-by-step explanation:
The probability is defined as the ratio of number of elements in event to the number of elements in sample space.
(a) As the total number of child is 3, so the number of elements in sample space = 3
(b) The sample space is { boy, boy, girl}
So, the probability is 1/3.
Answer:I think it’s 3.25(3)+6c=$21.75, I’m not sure
Step-by-step explanation:
The domain is set of all x-values. From an ordered pair (x,y) the domain would be the value of x. That means y-value is clear out since it is not domain but range or co-domain.
Given the set of relations below:
R = {(3,-2), (1,2), (-1,-4), (-1,2)}
The domain would be {3,1,-1} which if we arrange from least to greatest, we'd get {-1,1,3}. Remember that we don't write the repetitive numbers or same two numbers in the set.
Answer
parallel to the line y = 5x - 3, so the other lines must have same slope m = 5
y - y1 = m(x - x1)
y - 5 = 5(x-2)
y = 5x - 10 + 5
y = 5x - 5
Given that cos Ф = 5/6 I know that one side is 5 and the hypotenuse is 6 so the other side is:
a^2 = c^2 - b^2
a^2 = 6^2 - 5^2
a^2 = 36 - 25 = 11
a =
Now I know that the sin is
since sin is defined as opposite/hypotenuse
the second one uses a form of C = pi * d we are going to add the sector part to it.
C = 6 and the central angle is 4 degrees we can set up like this:
d = 171.974
r = 171.94/2 =85.987
