O D. 0.684 and 0.1222...
Answers
Answer:
B.) 0.684 and 0.122
Step-by-step explanation:
A number that cannot be expressed as a ratio between two integers and is not an imaginary number. If written in decimal notation, an irrational number would have an infinite number of digits to the right of the decimal point, without repetition. Pi and the square root of 2 (√2) are irrational numbers.
pi = 3.14159265359.....
e = 2.71828182845.....
Both are irrational

You have 26 red cards and 26 black cards. You randomly select a card (don't put it back in the box). Then you go to randomly select another card.

They are interested in the number of goals they make each kick is either a goal or not).

(a) You have a drawer filled with 20 balls, which are colored black or white. You have 12 black and 8 white balls. You randomly select a ball, record the color, and put the ball back into the drawer. Then you go to randomly select another from the drawer. Is the probability that the second pick is white independent of what the first ball color was?
yes. This is because they are independent events. The fact that you returned the first ball back to the drawer makes the initial conditions the same so the probability of picking a white ball is the same as in the first attempt.
(b) You have a box containing 52 cards, which are either red or black. You have 26 red cards and 26 black cards. You randomly select a card (don't put it back in the box). Then you go to randomly select another card. Is the probability that the second pick is diamond independent of what the first card was?
No. This is because the total number of cards in the box has changed since you didn't put the first card back. For example, the probability of picking a diamond on the first try is: P=13/52=1/4 = 25%. But when you pick the first card and don't put it back in the box, then the probability changes. If the first card was a card other than a diamond card, then the probability will now be: P=13/51=25.5% the probability has increased. If the first card you picked was a diamond, then the probability would be still different: P=12/51=23.5% so the probability of picking a diamond on the second attempt has decreased.
(c) A basketball player is going to do a free throw 100 times at practice. They are interested in the number of goals they make each kick is either a goal or not). If each free throw attempt is independent with a 90% chance (0.90 probability) of being a goal, then is the total number of free throws that are goals in the 100 attempts following a binomial distribution?
Yes. For it to be a binomial distribution you must only have two independent outcomes. In this case, the outcomes are the shot being a goal or not. The probability for it being a goal is 90% and the probability for it not being a goal is 10%. So it is a binomial distribution.
(d) A soccer ball player is going to do 50 free kicks at practice. They are interested in the number of successes they make. If each kick is independent, but the player begins to make more free kicks the more attempts they make the probability they succeed increases the more attempts they take, P is increasing), then is the total number of successes made in the 50 attempts following a binomial distribution?
No. This is because the outcomes of a binomial distribution must remain constant independently on the number of attempts. Since the probability increases with the number of outcomes, then the outcomes will not be independent so it becomes a hypergeometric distribution.
(e) Your girlfriend has a box filled with scraps of paper, which have the names of movies (including the one you don't like). Your girlfriend randomly selects a scrap of paper from the box, reads it out loud, and sets the paper aside. Your girlfriend then randomly selects another paper. Is the probability that the second pick is the one you don't like independent of what the first picked movie was?
No. This is because the number of possible outcomes will decrease as she sets the paper aside. If the first movie she picked was a movie you like, then the probability that the second movie she picks is the one you don't like increases. If the first movie she picked was the movie you don't like, then the probability that on the second try she picked the movie you don't like decreases to zero since it has alreay been picked.
(f) Your wife has a box filled with scraps of paper, which have the names of restaurants including the first place you went out with her). Your wife randomly selects a scrap of paper from the box, reads it out loud, puts the paper back in the hat, and mixes up the scraps of paper. Your wife then randomly selects another paper. Is the probability that the second pick is the first place you went out with her independent of what the first name was?
yes. This is because when she puts the paper back in the lot, then the total number of papers in the box is the same as in the first try. In this case the number of possible outcomes and the number of desired outcomes are the same as in the first try, so the probability is the same no matter what the first pick was.

What is linear system?A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
The equations are given below.
2x − y = 3
x + 2y = −6
Then the solution to the equation will be given by the elimination method. Then we have the equation.
4x − 2y = 6 ...1
x + 2y = −6 ...2
Add equations 1 and 2, then we have
5x = 0
x = 0
Then the value of y will be
2y = −6
y = −3
Then the solution of the linear system of the equation is (0, −3).
And the graph is given below.

x = -3
Step-by-step explanation:
y = -x + 2
7x + 4y = -1
Subsitution method: (Substitute y)
7x + 4(-x+2) = -1
Expand.
7x + (-4x + 8) = -1
One plus and one minus make one minus. Two plus makes a plus.
7x -4x + 8 = -1
Simplify.
3x + 8 = -1
Isolate 3x.
3x = -1-8
= -9
Find x.
x = -9 ÷ 3

In a management trainee program at Claremont Enterprises, 80 percent of the trainees are female and 20 percent male. Ninety percent of the females attended college, and 78 percent of the males attended college.
a. A management trainee is selected at random. What is the probability that the person selected is a female who did not attend college?
b. Are gender and attending college independent? Why?
c. Construct a tree diagram showing all the probabilities, conditional probabilities, and joint probabilities.
d. Do the joint probabilities total 1.00? Why?
Answers
Answer: a. 8% ; b. Not independent; c. See tree diagram; d. Yes
Step-by-step explanation:
a. Let F = Females
M = Males
C = Those that attend college
P(F) = 80% = 0.8
P(M) = 20% = 0.2
P(C/F) = 90% = 0.9
P(C/M) = 78% = 0.78
If 90% of the females go to college, it means that 10% don't go to college.
We then use the multiplication rule and we'll get:
= 80% × 10%
= 0.8 × 0.1
= 0.08
= 8%
b. An independent event is one that the occurence of one event doesn't affect the other event from happening. However, this is not independent as the occurence of the events affect each other.
c. See attachment
The joint probability on the tree diagram will be:
= 0.72 + 0.08 + 0.156 + 0.044
= 1.00

Step-by-step explanation:
. An urn contains six colored balls: four orange and two blue. Two balls are selected at random without replacement, and you are told that at least one of them is orange. What is the probability that the other ball is also orange?
Answers
Answer:
We draw two balls. We know that one of them is orange.
Let's suppose that the first one is the orange.
Then after drawing that, we know that there are 5 balls left in the urn, and only one will be orange.
Then the probability of drawing the other orange ball is equal to the quotient between the number of orange balls and the total number of balls.
P1 = 1/5.
And now let's consider the other case, where we know that in the second draw we will draw an orange ball.
Then the probability of drawing an orange ball in the first draw is equal to the quotient between the number of orange balls (at the beginning we have 2) and the total number of balls (6)
P2 = 2/6
As those represent different cases (we assume different conditions for each one), the probability that we draw two orange balls, knowing for sure that we will draw one, is equal to the sum of these probabilities.
P = P1 + P2 = 1/5 + 2/6 = 6/30 + 10/30 = 16/30 = 8/15
