when mr. adams calculated his students' algebra test scores, he noticed that two students had extremely low scores. which measure of central tendency is affected most by the scores of these two students?
Answers
Mean has been affected most by the scores of these two students.
A bunch of scores is averaged to form the mean. The total scores were divided by the total scores. When population samples are tiny, the mean is susceptible to extreme scores.
When you add up all the individual scores and divide that total by the number of students, you obtain the mean, which is the arithmetic average score.
The average performance of a group of students on a test is represented by their mean scale score. A mean scale score is derived specifically by summing together the scores of each individual student and dividing that amount by the number of scores. It is additionally known as an average.

Answers
8 children are divided into 2 teams each containing 4 children to play a game against each other. 105 different divisions are possible.
Permutation:
In mathematics, permutation refers to the process of placing all members of a set into an order or sequence. In other words, if the set is already ordered, the permutation of its elements is called permutation. Substitutions occur in more or less noticeable ways in almost all areas of mathematics. They often occur when different orders are considered in a particular finite set.
Combination:
Combining is a way of selecting items from a collection, and (unlike permutation) the order of selection does not matter. In smaller cases you can count the number of combinations. Combining refers to combining n things, taken k times at once, without repetition.
According to the Question:
The first team can be chosen in ⁸C₂ = 28 ways.
After that, there are 6 people left, from which there are ⁶C₂ = 15 ways to choose the second team.
Then, there are 4 people left, out of which ⁴C₂ = 6 ways he can choose the third team. There is only one way to choose the fourth and final team from the remaining two.
In the above procedure, each occasion of splitting eight into her two his four teams counted as 4!= 24 times.

how to prove the median of a trapezoid is parallel to the bases and equal in length to the average of their lengths?
Answers
The median of a trapezoid is parallel to the bases and equal in length to the average of their lengths. This is due to the midpoint theorem and the definition of the average.
The median of a trapezoid is a line segment that connects the midpoints of the non-parallel sides of the trapezoid. By the definition of a trapezoid, the two parallel sides (the bases) are of equal length.To prove that the median of a trapezoid is parallel to the bases and equal in length to the average of their lengths, we will make use of the midpoint theorem and the definition of the average.First, let's look at the midpoint theorem: If two points are the midpoints of two sides of a trapezoid, then the line connecting them is parallel to the bases. Now, let's look at the definition of the average: The average of two numbers is equal to the sum of the numbers divided by two.Now, let's apply these two concepts to the median of a trapezoid. As stated above, the median of a trapezoid connects the midpoints of the non-parallel sides of the trapezoid. By the midpoint theorem, the line connecting the midpoints of the non-parallel sides of the trapezoid is parallel to the bases. Next, we need to prove that the median of a trapezoid is equal in length to the average of the lengths of the bases. We can do this by noting that the length of the median of a trapezoid is equal to the sum of the lengths of the bases divided by two. This is because the median line segment connects the midpoints of the bases, so the length of the median is equal to half the sum of the lengths of the bases.Therefore, we can conclude that the median of a trapezoid is parallel to the bases and equal in length to the average of their lengths.Learn more about median here

Answers
The method that solves initial values problem by using sloped at two points is Heuns method.
Therefore the answer is B. Heuns method.
The Heun's method, also known as the improved Euler method, is a numerical method used to solve initial value problems for ordinary differential equations. It is a second-order method, which means that it uses the slope at two points (the starting point and one other point) to estimate the solution at a future point.
Heun's method is an explicit method which is an extension of the Euler method, by using the slope at the midpoint between the current and the next steps to improve the accuracy of the solution.
Euler method is a first-order method which estimates the solution at a future point by using the slope at one point only.
RK method is a family of methods that ranges from first-order to fourth-order method, but it uses a combination of the slopes at different points to estimate the solution.
Picard's method is a method of solving differential equations that is based on the idea of repeatedly applying a function to an initial value until a fixed point is reached. It's a method that does not use slopes.

Answers
More data needs to be collected to be able to conclude if more than half the students regularly recycle as the dotplot shows the results are variable.
1. Calculate the proportion of students who reported recycling in the sample:

3. Calculate the standard error: SE
= sqrt(0.50*(1-0.50)/100)

Answers
The volume of the new box is 30 units^3.
We can infer the roots are rational integers from the response options, thus this polynomial ought to be simple to factor. The coefficients of x must multiply by 10, hence they must be in some sequence of 5,2,1 or 10,1. Since we can try each one separately, we can express the factored form as follows:
(5x-p)(2x-q)(x-r)
Due to the fact that p, q, and r must multiply to 6, they must be either 3,2,1 or 6,1,1 in some sequence. Once more, we may test each one in a different place to determine if they multiply properly.
When we multiply the x-terms and attempt (5x-2)(2x-1)(x-3), the answer is 29. Try adding the x^2 terms together; they equal -39. Consequently, the roots are [tex]\frac{2}{5} , \frac{1}{2} and 3.[/tex] Now if you add 2 to each root, you get the volume is

Marcel just started her own business making cookies. She sells the cookies in boxes, charging $15.00 per box. It costs her $50.00 to buy the supplies. She wants to calculate how many boxes she must make to earn a profit of at least 245.00.
Answers
Answer:
Step-by-step explanation:
To calculate how many boxes of cookies Marcel needs to make to earn a profit of $245.00, we need to use the following formula:
Profit = (Revenue - Expenses) / Number of boxes
We know that the revenue is $15.00 per box and the expenses are $50.00. We also know that the profit should be at least $245.00.
So we can substitute these values into the formula and solve for the number of boxes:
$245.00 = ($15.00 - $50.00) / x
Where x is the number of boxes.
To solve for x, we'll need to multiply both sides of the equation by x:
$245.00*x = ($15.00 - $50.00)
$245.00*x = -$35.00
x = -$35.00/$245.00 = -0.142857143
The number of boxes is a negative value which is not possible, so Marcel will not earn a profit of $245.00. She will need to increase her revenue or decrease her expenses to reach a profit of $245.00.

Answer:
[tex]\frac{-1}{2}[/tex]
Step-by-step explanation:
Rate of change = [tex]\frac{Change in Y value}{Change in X value}[/tex]
Pick any two sets of 'X' and 'Y' value
I chose (-4, 6) as [tex](X_{1} ,Y_{1} )[/tex]and (12, -2) as [tex](X_{2} ,Y_{2} )[/tex] :
Rate of change = Slope / Gradient of graph = [tex]\frac{Y_{2} -Y_{1} }{X_{2} - X_{1} }[/tex]
= [tex]\frac{-2 - (6)}{12 - (-4)}[/tex]
= [tex]\frac{-2 - 6}{12 + 4}[/tex]
= [tex]\frac{-8}{16}[/tex]
= [tex]\frac{- 1}{2}[/tex]
