In maths, A∩B refers to the intersection of two sets, A and B. This means that it includes all the elements that are in both sets A and B. For example, if A = {1, 2, 3, 4} and B = {3, 4, 5, 6}, then A∩B = {3, 4}, as these are the elements that are in both sets.
To find the intersection of two sets, you can list out all the elements in each set and then look for the ones that are in both. Alternatively, you can use a Venn diagram to visually represent the two sets and their intersection.
Here is an example using a Venn diagram:
A = {1, 2, 3, 4}
B = {3, 4, 5, 6}
As you can see, the intersection of A and B is the area where the two circles overlap, which includes the elements 3 and 4. Therefore, A∩B = {3, 4}.

quadrilateral, as shown below.
Calculate the size of angle p.
Give your answer in degrees (°).
In the given figure , the measure of angle p is 41 degrees.
What is Quadrilateral ?A quadrilateral is a closed figure that has four sides, four vertices, and four angles. It is a form of polygon. In order to create it, four non-collinear points are joined. Quadrilaterals always have a total internal angle of 360 degrees.
It is given that the kite is shares a side with an equilateral triangle to form a new quadrilateral.
The side of kite which is attatched to triangle contains an angle of 79 degree.
the other end of side which is attatched to the triangle contains angle of 120 degree because it is attatched to the side of triangle which makes a straight line and the triangle is having each angle of 60 degrees.
So, the angle opposite to it will also be of 120 degrees.
Now in the kite, the angles are,
79+120+p+120=360
p=360-319
p=41 degrees
Hence, the measure of angle p is 41 degrees.

The value of x from the right triangle is x = 3√11
What is a Triangle?A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
if a² + b² = c² , it is a right triangle
if a² + b² < c² , it is an obtuse triangle
if a² + b² > c² , it is an acute triangle
Given data ,
Let the first triangle be ΔABC
Let the second triangle be ΔDBC
Now , BD is perpendicular to AC
So , the triangles ΔABC and ΔDBC are similar
The measure of BD = x
The measure of AD = 9
The measure of DC = 20
Now , AD / AB = AB / DC
Substituting the values in the equation , we get
9/a = a/20
On simplifying the equation , we get
a² = 180
So , a = 3√20
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
Now , the measure of x = √ ( 3√20 )² - ( 9 )²
So , the measure of x = √ ( ( 180 ) - 81 )
The measure of x = √ 99
The measure of x = 3√11
Hence , the measure of x of triangle is 3√11

The diameter C of the top of a randomly selected large drink cup at a fast-food restaurant follows a Normal distribution with a mean of 3.96 inches and a standard deviation of 0.01 inch.
The diameter Lof a randomly selected large lid at this restaurant follows a Normal distribution with mean 3.98 inches and standard deviation 0.02 inch.
Assume that Land Care independent random variables. Let the random
variable D = L - C be the difference between the lid's diameter and the
cup's diameter.
For a lid to fit on a cup, the value of L has to be bigger than the value of C, but not by more than 0.06 inch. Find the probability that a randomly selected lid will fit on a randomly selected cup.
Interpret this value. Justify your answer.
The required probability that a randomly selected lid will fit on a randomly selected cup is 0.9772, or 97.72%.
What is a normal distribution?Normal distributions can be altered to standard normal distributions by the formula:
Z = (X - μ)/σ
The difference in diameter between the lid and cup, D = L - C, is also a normal distribution with mean μ(D) = μ(L) - μ(C) = 3.98 - 3.96 = 0.02 inches and standard deviation σ(D) = √(σ² (L)+ σ²(C)) = 0.03 inches.
The probability that a randomly selected lid will fit on a randomly selected cup is the probability that D is between 0 and 0.06 inches. To find this probability, we can standardize D using the z-score formula and find the corresponding area under the standard normal curve.
Let z = (D - μ) / σ.
Then, the required probability is,
P(0 < D < 0.06) = P(0 < z < (0.06 - 0.02) / 0.03) = P(0 < z < 2).
We can use a standard normal table or a calculator to find the area under the standard normal curve between 0 and 2. This area represents the required probability. For example, using a standard normal table, we can find that P(0 < Z < 2) = 0.9772.
Therefore, the probability that a randomly selected lid will fit on a randomly selected cup is 0.9772, or 97.72%.

A Plus Landscaping Company has a big job where they need 83 bushes and 22 trees.They need to compare the costs from two similar suppliers; Pinedale Plants and Sierra Shrubs. Last month A Plus Landscaping placed two orders with Pinedale Plants. The first order was for 10 bushes and 5 trees and totaled $393.6 before taxes. The second order was for 5 bushes and 2 trees and totalled $177.32 before taxes. The bills from Pinedale Plants do not list the per-item price. A Plus Landscaping has an offer from Sierra Shrubs where similar bushes cost $18.27 and trees cost $41.96.
Answer: To compare the costs between the two suppliers, we need to find the total cost of 83 bushes and 22 trees from each supplier.
For Pinedale Plants:
The first order was for 10 bushes and 5 trees, so the cost per bush is $393.6 / 10 = $39.36.
The second order was for 5 bushes and 2 trees, so the cost per bush is $177.32 / 5 = $35.464.
To find the average cost per bush from Pinedale Plants, we can take the average of the two costs: ($39.36 + $35.464) / 2 = $37.412
The total cost from Pinedale Plants for 83 bushes would be 83 * $37.412 = $3108.976
The total cost from Pinedale Plants for 22 trees would be 22 * $35.464 (since the cost per tree was not specified), which is $777.75
The total cost from Pinedale Plants for 83 bushes and 22 trees would be $3108.976 + $777.75 = $3886.726
For Sierra Shrubs:
The cost per bush from Sierra Shrubs is $18.27
The total cost from Sierra Shrubs for 83 bushes would be 83 * $18.27 = $1510.01
The cost per tree from Sierra Shrubs is $41.96
The total cost from Sierra Shrubs for 22 trees would be 22 * $41.96 = $923.12
The total cost from Sierra Shrubs for 83 bushes and 22 trees would be $1510.01 + $923.12 = $2433.13
So, we can see that the total cost from Sierra Shrubs for 83 bushes and 22 trees is lower than the total cost from Pinedale Plants. The company would save $3886.726 - $2433.13 = $1453.596 by ordering from Sierra Shrubs.

h = 10.0708 cm
Area of shaded region = 8.1841 [tex]cm^{2}[/tex]
Step-by-step explanation:
r = radius of circle
= 14 cm
h = perpendicular height of triangle
Use SinФ trigonometric function to determine h
SinФ = [tex]\frac{Opposite}{Hypotenuse}[/tex]
Sin46° = [tex]\frac{h}{14}[/tex]
Cross-multiplication is applied:
∴h = (14)(Sin46°)
h = 10.0708 cm (Rounded to four decimal places)
Area of sector = [tex]\frac{AngleOfSector}{360^{o}}[/tex] × ([tex]\pi r^{2}[/tex])
= [tex]\frac{46}{360}[/tex] × [tex]\pi (14^{2})[/tex]
= [tex]\frac{9016}{360} \pi[/tex] [tex]cm^{2}[/tex]
= 78.68 [tex]cm^{2}[/tex]
Area of triangle = [tex]\frac{1}{2}[/tex] × (Base of triangle) × h
= [tex]\frac{1}{2}[/tex] × (14 cm) × [(14)(sin46°)]
= (98)(sin46°)
= 70.50 [tex]cm^{2}[/tex]
∴Area of yellow shaded region = Area of sector - Area of triangle
= {[[tex]\frac{9016}{360} \pi[/tex]] - [(98)(sin46°)]} [tex]cm^{2}[/tex]

The depth of the river dropped from 5 feet in 1846 to 4.9 feet in 1847. The change in depth can be calculated as:
Change in depth = 4.9 - 5 = -0.1 feet
So, the depth of the river dropped by 0.1 feet between 1846 and 1847.
Change in depth between 1847 and 1848:
The depth of the river rose from 4.9 feet in 1847 to 6.4 feet in 1848. The change in depth can be calculated as:
Change in depth = 6.4 - 4.9 = 1.5 feet
So, the depth of the river increased by 1.5 feet between 1847 and 1848.

Solving the Question
[tex]\dfrac{2}{3}x=6[/tex]
Our goal is always to isolate x.We can do that by performing inverse operations⇒ ex. the inverse of addition is subtractionHere, we have to get rid of the [tex]\dfrac{2}{3}[/tex] by dividing both sides by it.[tex]\dfrac{\frac{2}{3}x}{\frac{2}{3}}=\dfrac{6}{\frac{2}{3}}\\\\x=\dfrac{6}{\frac{2}{3}}\\\\x=6\div\dfrac{2}{3}[/tex]
Dividing by a fraction is the same as multiplying by its reciprocal:[tex]x=6\times\dfrac{3}{2}\\\\x=\dfrac{18}{2}\\\\x=9[/tex]

suppose that a classroom has 4 light bulbs. the probability that each individual light bulb works is 0.25. suppose that each light bulb works independently of the other light bulbs. what is the probability that all four of the light bulbs work?
The Probability that all four of the light bulbs work is 0.004 approx.
The probability that all four light bulbs work can be calculated by taking the product of the probability that each individual light bulb works. If each light bulb works independently of the other light bulbs, then the probability that all four light bulbs work is:
P(all 4 bulbs) = P(bulb 1) * P(bulb 2) * P(bulb 3) * P(bulb 4)
P(all 4 bulbs) = 0.25 * 0.25 * 0.25 * 0.25
P(all 4 bulbs) = 0.25^4
P(all 4 bulbs) = 0.00390625
So, the probability that all four light bulbs work is 0.00390625 or approximately 0.004.
