If necessary, round your answer to 222 decimal places.
Answer:
The probability of picking a black card at random, from a deck with 3 black cards and 7 red ones is 0.3.
Step-by-step explanation:
We will assume that we have 3 black cards and 7 black cards, for a total of 10 cards. Since we are taking one card at random, we can assume that each card is equally likely to be drawn. We have the following event A: The drawn card is a black. We will find the probability of A as counting the number of outcomes that make A to occur and divide it by the total number of possibilities. We are drawing one card, so we have 10 possibilities to be picked. Out of those 10, only 3 cards are black, hence we have 3 possibilites of picking a black card.
Then,
P(A) = 3/10 = 0.3.

Answer:
1. n[(A U B) - C] = {23, 24, 27, 29, 33, 36, 37, 39, 41, 42, 43, 45, 47, 48, 51, 53, 54, 57, 59, 61, 63}
2. n[(A - B) U C] = n[A U C] = {6, 10, 12, 15, 20, 23, 29, 30, 31, 37, 41, 43, 47, 53, 59, 60, 61}
3. D. I, II and III.
Step-by-step explanation:
U = {21, 22, 23, ..., 64}
A prime number is a number that can be divided only by 1 and itself.
A = {23, 29, 31, 37, 41, 43, 47, 53, 59, 61}
B = {24, 27, 30, 33, 36, 39, 42, 45, 48, 51, 54, 57, 60, 63}
C = {6, 10, 12, 15, 20, 30, 60}
1. Find n[(A U B) - C]
n(A U B) = {23, 24, 27, 29, 30, 33, 36, 37, 39, 41, 42, 43, 45, 47, 48, 51, 53, 54, 57, 59, 60, 61, 63}
n[(A U B) - C] = {23, 24, 27, 29, 30, 33, 36, 37, 39, 41, 42, 43, 45, 47, 48, 51, 53, 54, 57, 59, 60, 61, 63} - {6, 10, 12, 15, 20, 30, 60}
Since only 30 and 60 are common to n(A U B) and C, we therefore remove them it and have:
n[(A U B) - C] = {23, 24, 27, 29, 33, 36, 37, 39, 41, 42, 43, 45, 47, 48, 51, 53, 54, 57, 59, 61, 63}
2. Find n[(A - B) U C]
To get n(A - B) we remove all the elements of B in A. Since there are no common elements between A and B, we therefore have:
A - B = A = {23, 29, 31, 37, 41, 43, 47, 53, 59, 61}
C = {6, 10, 12, 15, 20, 30, 60}
Therefore, we have:
n[(A - B) U C] = n[A U C] = {6, 10, 12, 15, 20, 23, 29, 30, 31, 37, 41, 43, 47, 53, 59, 60, 61}
3. Which of the following is/are true?
I. A ∩ B = A ∩ C
A ∩ B = ∅
A ∩ C = ∅
Therefore, A ∩ B = A ∩ C is true.
II. A - B = A - C
A - B = A = {23, 29, 31, 37, 41, 43, 47, 53, 59, 61}
A - C = A = {23, 29, 31, 37, 41, 43, 47, 53, 59, 61}
Therefore, A - B = A - C is true.
III. A ∩ (B ∪ C) = ∅
A = {23, 29, 31, 37, 41, 43, 47, 53, 59, 61}
B U C = {6, 10, 12, 15, 20, 24, 27, 30, 33, 36, 39, 42, 45, 48, 51, 54, 57, 60, 63}
Therefore, A ∩ (B ∪ C) = ∅ is true.
Therefore, the correct option is D i.e. I, II and III are true.

Answer:
x ≈ 33
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan67° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{x}{14}[/tex]
Multiply both sides by 14
14 × tan67° = x, thus
x ≈ 33 ( to the nearest whole number )

Answer:
Slope = 4
Step-by-step explanation:
Hi!
So, I can only see question a, so I will answer that.
This is asking for the slope given 2 points.
The line-slope formula states :
[tex]m = \frac{(y_{2}-y_{1})}{(x_{2}-x_{1})}[/tex]
where m is the slope and the x and y values are the corresponding values from 2 coordinate points. The hard part of this is deciding which of your points is point 1 and which is point 2. It's arbitrary, so any selection is correct. We just have to stay consistent.
Let's let (3,12) be point 1 and (4,16) be point 2. Now we can write the corresponding x and y values into our formula:
[tex]m = \frac{({y_{2}-y_{1}})}{(x_{2}-x_{1})}\\m = \frac{(16-12)}{(4-3)}\\\\m = \frac{4}{1}\\\\m = 4[/tex]
So, the slope of the line through the 2 points (3, 12) and (3, 16) is 4

Svetlana has 1.2kg of apples and plenty of the other ingredients. She wants to make apple crumble for a maximum number of people. What is the maximum number of people she will be able to serve?
You must show your working
Answer: 12
Step-by-step explanation:
1200/750=1.6
1.6 X 8 = 12.8
12 number of maximum people she can serve.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Amount of Apples = 750 g
and, Svetlana has 1.2 Kg of apples
So, number of people she can serve
= 1200/750 x 8
= 1.6 x 8
= 12.8
= 12 people.
Hence, 12 number of maximum people she can serve.

If U is the a point in the interior of an equilateral triangle whose side is 20cm, then what is the sum of distances from
U to each sides of AABC?
Answer:
17.32 cm
Step-by-step explanation:
According to Viviani's theorem, the sum of the distances from an interior point to the sides of an equilateral triangle equals the height of the triangle.
In an equilateral triangle ΔABC, if U is an interior point, the sum of distances from U to each sides of ΔABC = height of triangle. Since each side of the triangle is 20 cm, we can find the height of the triangle (h)
This can be represented by a triangle with hypotenuse 20 cm, a leg of 10 cm (20/2) and the other leg h cm. Using Pythagorean theorem:
h² + 10² = 20²
h² = 400 - 100 = 300
h = √300 = 17.32 cm
Therefore, the sum of distances from U to each sides of ΔABC is 17.32 cm

A tin contains 20kg of ghee. Rao consumed 2⁄4 of it for preparing medicines. From the remaining ghee Rao used 2⁄5 and 1/2 of it for making laddu and burfi. How much ghee is left? *
Answer:
1kg ghee is left behind
Step-by-step explanation:
Here, we are to calculate the amount of ghee left.
Firstly, 2/4 was consumed for preparing medicine. This is same as 1/2
The amount used in preparing medicine is thus 1/2 * 20kg = 10kg
amount remaining = 20kg - 10kg = 10kg
She also use 2/5 and 1/2 of the remainder.
The total amount used is 2/5 + 1/2 = 9/10
The amount used is thus 9/10 * 10 = 9kg
what is left is thus 10kg -9kg = 1 kg

Answer:
x = 8
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² + 36 = 100 ( subtract 36 from both sides )
x² = 64 ( take the square root of both sides )

Answer:
320 tickets for 1200 shs and 680 tickets for 800 shs (multiply please)
Step-by-step explanation:
let; x - be the number of 1200 shs tickets.
y - number of 800 shs tickets.
x + y = 1000 tickets........................... eqtn 1
1200x + 800y = 928000 shs.........................eqtn 2
solve the simultaneous equation by elimination by multiplying eqtn 1 by 800 and eqtn 2 by 1 to be able to eliminate (y) when subtracting.

On a smooth plane mirror, if the angle of incidence is 30° then the angle of reflection is
1: 30 degrees
2: 60 degrees
3: 90 degrees
4: none of the above
EXPLAIN YOUR ANSWER.
Answer:
1: 30 degrees
Step-by-step explanation:
In Physics, we have the law of reflection. This law states that when light rays hit the smooth surface of mirror or any smooth polished surface, the angle of incidence is equivalent to the angle of reflection.
Mathematically:
Angle of incidence = Angle of reflection
From the above question, the angle of incidence is on a smooth plane mirror = 30°
Since:
Angle of incidence = Angle of reflection
30° = 30°
Therefore, based on the law of reflection, the Angle of reflection = 30°

Use the information provided to write the equation of each circle. *photo attached
Answer:
( x + 13 )^2 + ( y + 6 )^2 = 1; Option A
Step-by-step explanation:
~ The question we have at hand is: x^2 + y^2 + 26x + 12y + 204 = 0 ~
Let us apply the circle equation ( x - a )^2 + ( y - b )^2 = r^2 ⇒ provided r is the radius, centered at point ( a, b )
1. First rewrite x^2 + y^2 + 26x + 12y + 204 = 0 in the standard form of circle equation: x^2 + y^2 + 26x + 12y + 204 = 0
2. Now move the loose number to the right side: x^2 + 26x + y^2 + 12y = -204
3. Let us now group variables: ( x^2 + 26x ) + ( y^2 + 12y ) = -204
4. Convert x to square form: ( x^2 + 26x + 169 ) + ( y^2 + 12y ) = -204 + 169
5. Convert to square form: ( x + 13 )^2 + ( y^2 + 12y ) = -204 + 169
6. Convert y to square form: ( x + 13 )^2 + ( y^2 + 12y + 36 ) = -204 + 169 + 36
7. Convert to square form, and simplify: ( x + 13 )^2 + ( y + 6 )^2 = 1
Answer: ( x + 13 )^2 + ( y + 6 )^2 = 1

No, -3 is greater than -24
Hope this helps! Please mark brainliest :)
Answer: No
Step-by-step explanation: To find out if this ordered pair is a solution to the following inequality, simply plug the values in for x and y.
So we have -3 < -5(3) + 3(-3) or -3 < -15 + -9 or -3 < -24.
Since -3 < -24 is a false statement, the ordered pair
(3, -3) would not be considered a solution.
