Answer:
a=14
Step-by-step explanation:
if a=10, 10/2 = 5 plus 9 = 14
For x and y
When you subtract 2 from x, you will subtract 7 from y
Answer:
see below
Step-by-step explanation:
4a) x / 12 = 5
multiply both sides of equality by 12
x = 60
4b) Dan charges $12 per hour, this doesn't change so it's the constant of proportionality.
4c) S = 12h
If you substitute the h with the number of hours worked multiply with the constant of proportionality 12 you'll get the amount charge S.
5) Equation for a slope is (y₂ - y₁) / (x₂ - x₁):
(2 - 0) / (6 - 1)
= 2/5

A = event that the ball drawn from urn #1 is white
B = event that the ball drawn from urn #2 is white
P(A) = probability of event A
P(A) = (number of white in urn #1)/(number total in urn #1)
P(A) = 3/(3+6)
P(A) = 3/9
P(A) = 1/3
P(B) = probability of event B
P(B) = (number of white in urn #2)/(number total in urn #2)
P(B) = 3/(3+8)
P(B) = 3/11
Because A and B are independent events, we can multiply the probabilities
P(A and B) = P(A)*P(B)
P(A and B) = (1/3)*(3/11)
P(A and B) = (1*3)/(3*11)
P(A and B) = 1/11
Answer: Choice A) 1/11
