Total applications = 75
Apartments on north side of town = 4
Apartments on South side of town = 5
First person has a 4/75 chance of getting a house in the north side
P(A) = 4/75
And second person has a 3/74 chance of getting a house in the north side
P(B) = 3/74
Probability that 2 qualified applicants will be selected for the north side of town = P(A∩B) = P(A) x P(B) = (4 ÷ 75) x (3 ÷ 74) = 0.05333 x 0.04054 = 0.00216
First person has a 5/75 chance of getting a house in the south side
P(A) = 5/75
And second person has a 4/74 chance of getting a house in the south side
P(B) = 4/74
Probability that 2 qualified applicants will be selected for the south side of town = P(A∩B) = P(A) x P(B) = (5 ÷ 75) x (4 ÷ 74) = 0.06666 x 0.05405 = 0.00360
Answer:
Volume of 3% alcohol = 80 ml
Volume of 8% alcohol = 120 ml
Step-by-step explanation:
Final volume of 6% alcohol solution = 200 ml
Let the volume of 3% alcohol volume = a ml
Therefore, volume of 8% alcohol = (200 - a) ml
Equation for the given situation will be,
3a + 8(200 - a) = 6×200
3a + 1600 - 8a = 1200
1600 - 5a = 1200
5a = 400
a = 80 ml
Therefore, volume of 3% alcohol to be used = 80 ml
And volume of 8% alcohol to be used = (200 - 80) = 120 ml
14.
Subtracting a negative number is like adding a positive number. So, you can change 9 - (-5) into 9 + 5, which is much simpler. Then, just add to get 14.

<span>Assuming that Josh throws the discus 36 times, the expected value of y will be the length each discus reaches for each throw all added together. Specifically, it will be discus throw one, plus discus throw two -- all the way to discus throw thirty-six. Adding all of those throws together will provide the expected value of Y.</span>
