Answer:
x=5 , x=4, x=2
i got this answer by setting the x-5=0 then solve for x. same for each x-5, x-4, x-2.
Answer:
1/4
Step-by-step explanation:
Let's denote the probabilities as following:
Probability that a teenager has a sister:
P(A) = 12/28
Probability that a teenager has a brother:
P(B) = 7/28
Probability that a teenager has both a sister and a brother:
P(A⋂B) = 3/28
Probability that a selected teenager has a sister also has a brother, or in other words, he/she has a brother, given he/she had a sister:
P(B|A)
Let's apply the formula of conditional probability to work out P(B|A)
P(B|A) = P(A⋂B)/P(A) = (3/28)/(12/28) = (3*28)/(12*28) = 3/12 = 1/4
=> Option C is correct
Hope this helps!
Answer:
y = 10 when x = 5
Step-by-step explanation:
When x = 4, y = 8
Simplify. Divide 4 from both x and y
x = 4/4 = 1
y = 8/4 = 2
when x = 1, y = 2
Next, solve for when x = 5. Mutliply 5 to both x and y
x = 1 * 5 = 5
y = 2 * 5 = 10
y = 10 when x = 5
~
(8 times 4) - (2 times 3 = 8) divided by 2
