The probability of at most two hot peppers = 0.918
Total number of burritos ordered = 17
Number of burritos with hot peppers = 8
Number of burritos without hot pepper = 9
Number of burritos picked = 3
We need to find the probability of the event that at most two have hot peppers.
At most two have hot peppers means either there is one with hot pepper or there are two with hot pepper. So there should not be 3 burritos all with hot peppers.
Thus we can rewrite the probability that at most 2 out of 3 burritos are with hot peppers as, Total probability - the probability that all 3 burritos are with hot peppers.
So the probability that all three burritos are with hot peppers = P(3 with hot peppers) = (8C3x9C0)/17C3
= 56 x 1/680
= 0.082
Then the probability that at most two burritos out of three are with hot peppers = 1 - P(3 with hot peppers)
= 1 - 0.082
= 0.918

What do you mean by congruencey of the triangle?The dimensions of the sides and angles of two or more triangles determine whether they are congruent. A triangle's size and shape are determined by its three sides and three angles, respectively. Two triangles are said to be congruent if pairings of corresponding sides and corresponding angles are equal. They are the exact same size and form.
D is the midpoint of AC
so AB = BC
and also AD = CD
so the triangle ADB is congruent to triangle CDB

How to Determine the Graph of a System of Inequalities?The graph that would represent the system of inequalities must be two lines that intersect each other and have the exact slope and y-intercept of each of the lines on the graph.
Determine the slope and y-intercept of each of the inequalities, and also determine their boundary lines based on which inequality sign they have.
The line that represents the inequality, y ≥ ½x + 1, will be a solid line that has a slope of ½, and a y-intercept of 1.
The second line that represents the inequality, y ≥ -x - 2, will be a dashed line that has a slope of 1, and a y-intercept of -2.
Therefore, the graph that represents the features stated above for both lines is shown in the diagram below.

The two inlet pipes can fill the tank in 4 hours and 10 hours.
The work done by the inlet pipes per hour is calculated to be:

If the measure of ∠ C A B = 4 x + 14 and ∠ D A E = 6 x − 18 then find the measure of ∠ C A B
CAB and DAE are suplementary
Measure of CAB is 84.4, by using supplementary angle theory.
What is supplementary angle?
In geometry, two angles are referred to as supplementary angles if their sum is 180 degrees. For instance, if A + B = 180°, then A and B are considered supplementary angles. Complementary angles always result in a straight angle when combined (180 degrees).
Angles that add up to a precise 90 degree angle are said to be complementary. For instance, 30 degrees and 60 degrees are complementary angles.
We have given, CAB= 4x+14 and DAB = 6x-18
Both are supplementary angle
Therefore, CAB + DAB = 180
4x+14+6x-18=180
10x-4=180
10x=176
x=17.6
hence, CAB = 4(17.6)+14 = 84.4

In the accompanying diagram of BCD m
Given:
m∠C = 70°
m∠CDE = 130°
Question 1:
To find ∠CDB, let's use the exterior angle theorem.
The exterior angle theorem states that the sum of 2 opposite interior angles is equal to the exterior angle.
Thus,
m∠C + m∠B = 130
70 + m∠B = 130
Subtract 70 from both sides:
70 - 70 + m∠B = 130 -70
m∠B = 60°
Now, use the triangle angle sum theorem to find ∠CDB.
The triangle angle sum theorem states that the sum of interior angles in a triangle is 180°
∠CDB = 180 - 70 - 60 = 50°
∠CDB = 50°
Question 2:
∠CBA = ∠C + ∠CDB
∠CBA = 70 + 50 = 120°
∠CBA = 120°
ANSWER:
∠CDB = 50°
∠CBA = 120°

By Angle-Angle theorem similarity ΔABC is similar to ΔA'B'C'.
Given two triangles are ABC and A'B'C'.
What is a dilation?Dilation is the process of resizing or transforming an object. It is a transformation that makes the objects smaller or larger with the help of the given scale factor. The new figure obtained after dilation is called the image and the original image is called the pre-image.
1) Triangle ABC is reduced to triangle A'B'C'
∠ABC=∠A'B'C'=90°
∠BAC=∠B'A'C'
So, by AA similarity
ΔABC≈ΔA'B'C'
2) Triangle ABC is enlarged to triangle A'B'C'
∠ABC=∠A'B'C'
∠BAC=∠B'A'C'
So, by AA similarity

The key to doing this without the calculator is to take the cube of numbers and the one that has 20 in between them is the answer.
1³ = 1
2³ = 8
3³ = 27
We can see that 20 is between 8 and 27.

Given the equation:
y = 828000 - 2700x
Where y is the value of the building and x is the number of months of use.
Let's find when the value of the building will be $666,000.
To find when the value will be $666,000, substitute 666000 for y in the equation and solve for x.
y = 828000 - 2700x
666000 = 828000 - 2700x
Subtract 828000 from both sides:
666000 - 828000 = 828000 - 828000 - 2700x
-162000 = -2700x
Divide both sided by -2700:

Either Table A or Table B shows a proportional relationship.
Plot the points from the table that shows a proportional relationship.
( If you can, can you save the image as and edit it it will help me out a lot)
Answer: Table A has a proportional relationship
See the diagram below
==================================================
Explanation:
Table A has a proportional relationship because all the points are on the same straight line. That line in this case is y = 2x
Whatever x is, multiply it by 2 and you'll get the y value
Example: If x = 4, then y = 2*x = 2*4 = 8 which gives the point (4,8)
