Answer:
P(A)=0.25
P(B)=0.077
P(AB)=0.192
P(BA)=0.083
Check below for the full numbers, I rounded it for you.
Step-by-step explanation:
What is P(A), the probability that the card is a club?
So whenever you get a deck of cards you'll have 52 which have 4 suits, think of it like UNO, and club is one of the suit's name! This mean all this question is asking you is the probability of getting a club out of the 52 cards which is
52/4=13
So we know that there is 13 club cards.
Meaning the probability is a 25% since you can only get it 1/4 of the time.
P(A)=0.25
What is P(B), the probability that the card is a 5?
Same as what I stated earlier but this time you only have 4 cards that can be a "5" out of the 52 cards.
4/52=0.076923
P(B)=0.077
What is P(A and B), the probability that the card is a club and a 5?
Keep a eye on the working "and" this means it's referring to the possibility of getting a club and a 5 and since this can only happen once the chances are extremely slim.
1/52=0.1923076
P(AB)=0.192
What is P(BA), the conditional probability that the card is a 5 given that it is a club?
This assumes that you're only drawing from a deck of ONLY clubs so the chances of getting a 5 in that stack.
1/12=0.08333 (3 keeps going)
P(BA)=0.083
(This one might be wrong since I haven't done conditional probability in a long time but I feel somewhat confident, I do feel confident about the rest so no worries.)
Is P(BA) = P(B)? Are the events A and B independent?
No, P(BA) = P(B) is not true since A and B do influence one another since what if I get a 5 without replacement this results in change of chances of A.
Answer:
1.1/4
2.1/13
3.1/52
4.1/13
5. Yes p(B/A)=P(B) and Yes, events A and B are independent events.

In each problem, angle C is a right angle. Solve each triangle rounding answers to the nearest
tenth.
a= 7.7 ft, b= 16 ft
9514 1404 393
Answer:
c = 17.8, A = 25.7°, B = 64.3°
Step-by-step explanation:
Side c can be found from the Pythagorean theorem:
c = √(a² +b²)
c = √(7.7² +16²) = √315.29
c ≈ 17.8 . . . feet
__
The tangent relation is ...
Tan = Opposite/Adjacent
tan(A) = a/b = 7.7/16
A = arctan(7.7/16)
A ≈ 25.7°
B = 90° -25.7°
B = 64.3°

Answer:
2876 books
Step-by-step explanation:
If we let y1 and y2 represent the costs from method 1 and method 2, then we have, for x books published, ...
y1 = 12841 +24.25x
y2 = 48072 +12x
These costs will be equal when ...
y1 = y2
12841 +24.25x = 48072 +12x
12.25x = 35231 . . . . . . . . . . . . . subtract 12841+12x
x = 2876 . . . . . . . . . . divide by 12.25
The costs will be the same for production of 2876 books.

Ross wants to know what interest rate he needs to make his $800 grow to
$1000 in 4 years.
Answer:
Why?:
The interest formula is A = P(1+r/m)^mt
A is the Amount, P is principal (initial investment), R is rate, M is times per year (not used) and T is time.
So if we want 1000 = 800(1+r)^4, we need to find R. In this case, R is about 5 percent. (I'm not super confident, so see if you have other answers)

Answer:
1. sin(x) = a/c; cos(x) = b/c; tan(x) = a/b
2, 3 see below
Step-by-step explanation:
1. The mnemonic SOH CAH TOA reminds you of the relationships between trig functions and sides of a right triangle:
Sin = Opposite/Hypotenuse ⇒ sin(x) = a/c
Cos = Adjacent/Hypotenuse ⇒ cos(x) = b/c
Tan = Opposite/Adjacent ⇒ tan(x) = a/b
__
2. The attachment shows the two special right triangles. The 30-60-90 right triangle has sides in the ratio 1 : √3 : 2. The 45-45-90 isosceles right triangle has sides in the ratio 1 : 1 : √2.
These ratios can be used to write proportions that help you find the length of a missing side.
Example:
Suppose the triangle in problem 1 has x = 30°, and a = 10. Then we could find the length of missing side 'c' using a proportion involving the short side and the long side (hypotenuse).
2/1 = c/10 ⇒ c = 20
__
3. In a right triangle, the acute angles are complementary. The side adjacent to one acute angle is the side opposite the other. So the sine of one of the angles is the cosine of the other, and vice versa. This means the sine of an angle is the cosine of its complement, and vice versa.
__
Comment on question 3
The wording of this question is a little strange. Sine and cosine are not complementary. Rather, the angles for which those functions have the same value are complementary.
Roberto is 3 years older than Carolyn. In 7 years the sum of their ages will be 81. How old is Roberto now?
Answer: 35
the age of Roberto is x (x > 3)(x ∈ N)
because Roberto is 3 years older than Carolyn => the age of Carolyn is x - 3
in 7 years, the age of Roberto is x + 7; the age of Carolyn is x - 3 + 7 = x + 4
because In 7 years the sum of their ages will be 81 =>
x + 7 + x + 4 = 81
⇔ 2x + 11 = 81
⇔ 2x = 70
⇔ x = 70/2 = 35
=> the age of Roberto is 35

Find the equation of the linear function represented by the table below in slope intercept form.
Answer:
Y=1x-7
Step-by-step explanation:
First use two points to find the slope. I used the first 2. The formula is (y1-y2)/(x1-x2). So (6-8)/(1-3)= -2/-2 = 1. Then you plug in a point and the slope for the equation y1-y2=m(x1-x2). I am using the first point and m is the slope which is 1. Y-6 = 1(x-1)
y-6 = 1x -1 then get y by itself
y=1x-7
a metal washer has a mass of 0.27 G and a volume of 0.1 CM3 what is its density
Answer:
density equals mass over volume
D=.27G/ .1CM3
Step-by-step explanation:
hope this helps
Would someone mind helping me? I really need this answer but I'm so confused. I would appreciate any help :) and if you get the answer right, ill give you brainliest.
Answer:
A. the slope is -2
the y-intercept is (0,1)
Step-by-step explanation:
If y=mx+b, m is the slope and b is the y-intercept.
If we replace the variables with y=-2x+1, we can see -2 is the slope and the y-intercept is (0,1).

Mr. Roberts had $9,512 in savings. He saved another $488. He then used all his money to buy 500 books. He sold the books for $35 each. How much did Mr. Roberts earn from selling each book? a. Mr. Roberts earned $ from selling each book. b. Travis got $20 as the answer or the amount Mr. Roberts earned from selling each book. Is his answer correct? yes no c. Tell why Travis is or is not correct.
Answer:
a. Profit from each book = $15
b. No, Travis was wrong.
c. Travis isn't correct because Mr. Roberts made $15 from the sales of each book.
Step-by-step explanation:
Given the following data;
Number of books bought = 500
Selling price = $35
Robert savings (cost price) = $9,512 + $488
Robert savings (cost price) = $10,000
Purchasing price = $10,000/500 = $20
Revenues from book sold = 500 * 35 = $17,500
Total profit = Revenues - Cost price
Total profit = $17,500 - $10,000
Total profit = $7,500
To find the amount earned from each book;
[tex] Profit \; from \; each \; book = \frac {Total \;profit}{Numbers \; of \; book} [/tex]
Substituting into the equation, we have;
[tex] Profit \; from \; each \; book = \frac {7500}{500} [/tex]
Profit from each book = $15
Therefore, Mr. Roberts earned $15 from selling each book.
Check:
Selling price = purchasing price + profit = $20 + $15 = $35
