The least number of square yards of paper required to make the poster is 11 square yards.
How did we get the value?The area of a rectangle can be found by multiplying the length of its sides. To find the length and width of the rectangle, we can subtract the x and y values of the opposite vertices.
The length of the rectangle is 34 - 2 = 32 inches, and the width is -44 - 4 = -48 inches. We will have to make the width positive to find the area, so the area is 32 * 48 = 1536 square inches.
Since 1 square yard is equal to 144 square inches, we need to divide 1536 by 144 to find the number of square yards: 1536 / 144 = 10.67 square yards.
Therefore, the least number of square yards of paper required to make the poster is 11 square yards.

River says that KM is the
bisector of
error in River's reasoning.
The error in River's analysis is that it is known if LM and MJ are perpendicular to KL and KJ.
What is error analysis?
Error analysis is a technique used to track out errors in learner language, ascertain whether they are systematic, and (if possible) provide an explanation for why they occurred.
It is given that -
Line segment KM is the bisector of ∠LKJ.
Also, line segment LM = MJ.
According to the angle bisector theorem if a line is a bisector of an angle then the corresponding sides of the angle should be perpendicular to the third side which is getting bisected.
Although it is given that LM = MJ, but it is not known that if LM and MJ are perpendicular to the sides of ∠LKJ.
Therefore, River cannot conclude that KM is the bisector of ∠LKJ.

The function that is represented by the graph is y = ∛(x + 3) + 3.
What is a function?
In mathematics, a function is a unique arrangement of the inputs (also referred to as the domain) and their outputs (sometimes referred to as the codomain), where each input has exactly one output and the output can be linked to its input.
The general form of a cube root function is -
y = a∛(x - h) + k and the parent graph is y = ∛x.
So the parent function is found.
The coordinate point for the parent function is -
(-1,-1) , (0,0) and (1,1).
In the graph it can be seen that the coordinate points are -
(-4,2), (-3,3) and (-2,4)
So the graph is first moved 3 units up and then moved three units left.
So, the coordinated become - (x + (-3) , y + 3)
So, the function that represents the graph is -
y = ∛(x + 3) + 3
Therefore, the function is y = ∛(x + 3) + 3.

The ratio of the sides = 7: 3
The ratio of perimeter = 7: 3
The ratio of the areas = 49: 9
Area of green polygon = 23
Similar Polygons:The polygons which are in the same shape but different in size are known as similar polygons. For similar polygons, the ratio of sides is known as the scale factor which is equal to the ratio of perimeters. Here the ratio of the areas is the squares of the scale factor.
Note:
Area of a hexagon = [ 3√3 ]/2 × side²Here we have two polygons
Side of the yellow polygon = 7 units
By the given formulas,
Perimeter of polygon = 6(7) = 42 units
Area of the polygon = 127 units²
Side of the green polygon = 3 units
Perimeter of polygon = 6(3) = 18 units
Area of Polygon = (3√3)/2 × (3)² = 23.383 ≅ 23
The ratio of the sides of polygons yellow to green = 7: 3
The ratio of perimeter = 42: 18 = 7: 3
The ratio of the areas = (7/3)² = 49/9
=> 49: 9

The life (in hours) of a randomly chosen led light produced by a manufacturer is normally distributed with mean 1100 and standard deviation 70. Find the number of sample if the probability that the mean life is less than 1120 hours is 0.92
The sample size if the probability that the mean life is less than 1120 hours is 0.92 is given as follows:
n = 24.
How to obtain probabilities using the normal distribution?The z-score of a measure X of a variable that has mean symbolized by [tex]\mu[/tex] and standard deviation symbolized by [tex]\sigma[/tex] is obtained by the rule presented as follows:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score represents how many standard deviations the measure X is above or below the mean of the distribution, depending if the obtained z-score is positive or negative.Using the z-score table, the p-value associated with the calculated z-score is found, and it represents the percentile of the measure X in the distribution.By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].The parameters for this problem are given as follows:
[tex]\mu = 1100, \sigma = 70, s = \frac{70}{\sqrt{n}}[/tex]
The p-value of Z when X = 1120 is of 0.92, hence Z = 1.405, and the sample size is obtained as follows:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]1.405 = \frac{1120 - 1100}{\frac{70}{\sqrt{n}}}[/tex]

Write a story problem that can be represented by 8/3÷4 and explain why the division makes sense
A baker had 24 cupcakes and wanted to divide them equally among 8 friends. How many cupcakes would each friend receive?
The problem can be represented by 8/3 ÷ 4, where 8 represents the number of friends, 3 represents the number of cupcakes each friend should receive, and 4 represents the number of groups the cupcakes should be divided into.
The division makes sense because first, we need to find out how many cupcakes each friend should receive, which is 24 ÷ 8 = 3. Then, we divide the number of cupcakes each friend should receive by the number of groups to find out how many cupcakes each group should receive, which is 3 ÷ 4 = 0.75 cupcakes per group.

A spinner with 10 equally sized slices has 2 yellow slices, 4 red slices, and 4 blue slices. The dial is spun and stops on a slice at
random. What is the probability that the dial stops on a yellow or red slice?
Write your answer as a fraction in simplest form.
Answer: 3/5
The total number of slices is 10, and the number of yellow or red slices is 2 yellow slices + 4 red slices = 6 slices.
So, the probability of the dial stopping on a yellow or red slice is 6 slices / 10 total slices = 3/5.
This is the final answer, and it is already in its simplest form.

an = 3(6n)
an = 3(6n + 1)
an = 6(3n – 1)
an = 3(6n – 1)
The explicit rule for the nth term of the geometric sequence: 3, 18, 108, 648, 3,888, … is aₙ = 3( 6ⁿ⁻¹ )
What is the explicit rule for the nth term of the geometric sequence?The geometric sequence is expressed as aₙ = a₁ × rⁿ⁻¹
Given the set of numbers in the question;
3, 18, 108, 648, 3,888, …
The first term a₁ = 3
Next, we determine the common ratio r.
Divide a term by the previous term gives the common ratio.
Common ratio r = 18/3
Common ratio r = 6
Now, plug in the values of first and common ratio into the above formula to determine the nth term.
aₙ = a₁ × rⁿ⁻¹
aₙ = 3 × 6ⁿ⁻¹
aₙ = 3( 6ⁿ⁻¹ )
Therefore, the nth term of the sequence is aₙ = 3( 6ⁿ⁻¹ ).
Option D) aₙ = 3( 6ⁿ⁻¹ ) is the correct answer.

C) What is the best classification for the triangle?
Answer: x = 14; y = 74; Isosceles and Acute
Step-by-step explanation: 3(x+7) = 3x + 21
Isosceles triangles have congruent base angles making 63 = 3x +21
Solve for x.
All angles of a triangle add up to 180 making y = 180 - 63 - 63.
Isosceles because two sides are congruent. And acute because all angles are under 90.

If a tile pattern has an equation `y=-2x+10`, what does the number `-2` tell us about the tile pattern?
The value -2 is the rate of change of the linear equation.
What does the number -2 tell us about the pattern?A general linear equation is:
y = a*x + b
Where a is the rate of change and b is the y-intercept.
The rate of change tells us how the variable y changes when the variable x changes.
In this case we have:
y=-2x+10
So the "-2" is the rate of change, it tells us that each time that x increases 1 unit, the value of y decreases by 2 units.
