A.
The data shows a negative relationship between class size and number of absences.
B.
The data shows no relationship between class size and the number of absences.
C.
The largest class does not have the most absences.
D.
The smallest class does not have the least number of absences.

The statement which BEST describes why Trevor’s conclusion was incorrect is B. The data shows no relationship between class size and the number of absences.
What is Scatterplots?Scatterplots are the plotting of set of points on a vertical axis and an horizontal axis. The shows the correlation extent between the numbers of the observed quantities.
Given a scatterplot which shows the number of absences in a week for classes of different sizes.
From the scatterplot, we can see that,
For a class size of 15, there are 2 kind of absences, 2 and 10.
For class size of 20, there is a positive correlation.
Then again it increases and decreases for various sizes.
So there is no relationship in particular with the 2 variables.
Hence the correct option is B.

Geoffrey incorrectly found the margin of error because he used the wrong sample size.
Please give be brainliest, I really need it.
Geoffrey incorrectly found the margin of error because he used the wrong sample size. Therefore, the correct option is option B.
What is mathematical error?Measurement Error is the difference between the approximated value and the actual value of an object/quantity. The relative error can be computed in the percent with the help of relative error formula. Errors in measuring instruments occur due to inescapable faults in the measuring instrument and limitations of the human eye.
There are three types of errors in solving mathematics problems, which are factual error, procedural error, and computational error. Geoffrey incorrectly found the margin of error because he used the wrong sample size.
Therefore, the correct option is option B.

Quadrilateral ABCD has vertices A(- 3, 1), B(4, 2) B(4, 2), C(9, - 3) , and D(2, - 4) . aProve that quadrilateral ABCD is a rhombus b )Prove that ABCD is not a square .
Answers
9514 1404 393
Explanation:
The vectors representing the diagonals are ...
AC = C - A = (9, -3) -(-3, 1) = (12, -4)
BD = D - B = (2, -4) -(4, 2) = (-2, -6)
The dot-product of these vectors is the sum of the products of corresponding coordinates:
(12)(-2) +(-4)(-6) = -24 +24 = 0
When the dot-product is zero, the vectors are perpendicular. These vectors are different lengths (BD = 1/2·AC), so they are not the diagonals of a square.
__
The midpoints of the diagonals will be in the same place if the quadrilateral is a rhombus.
(A +C)/2 = (B +D)/2
We can simplify our effort a bit by multiplying by 2.
A+C = B+D
(9, -3) +(-3, 1) = (2, -4) +(4, 2)
(6, -2) = (6, -2) . . . . . . . . . . . . . . . . yes, the midpoints are the same point
__
We have shown the diagonals of the quadrilateral are different lengths and perpendicular bisectors of each other, so the quadrilateral IS A RHOMBUS, NOT A SQUARE.

To find:
The value of y.
Solution:
In a right angle triangle,
[tex]\tan \theta=\dfrac{Perpendicular}{Base}[/tex]
In triangle BGU,
[tex]\tan B=\dfrac{GU}{BU}[/tex]
[tex]\tan 44^\circ=\dfrac{7}{y}[/tex]

2nd DAY = 4M
3rd DAY = 4M
4th DAY = 4M
5th DAY = 4M
6th DAY = 4M
7th DAY = 4M
(The M next to the 4 means miles you don't have to include it in your answer on your homework!)

What does the 49 days until Fourth of July there are seven days in a week and how many weeks will it be Fourth of July
Answers
Answer:
It will be Fourth of July in 7 weeks.
Step-by-step explanation:
Since you know that there are seven days in a week, you can use a rule of three to find the amount of weeks in 49 days that is the number of days until Fourth of July:
7 days → 1 week
49 days → x
x=(49*1)/7
x=7
According to this, the answer is that it will be Fourth of July in 7 weeks.

Brett has 100 feet of fence with which to make a rectangular cage for his dog. The area of the cage in square feet is given by the polynomial where w is the width of the cage in feet. What is the area of the cage if the width is 8 feet?
Answers
Answer:
Area of rectangle cage = 336 feet²
Step-by-step explanation:
Given:
Wire required for fencing = 100 feet
Width of rectangular cage = 8 feet
Find:
Area of rectangle cage
Computation:
Wire required for fencing = perimeter of cage
Perimeter of rectangular cage = 100 feet
2[l + b] = 100 feet
l + 8 = 50 feet
Length of rectangular cage = 42 feet
Area of rectangle cage = Length x Width
Area of rectangle cage = 42 x 8
Area of rectangle cage = 336 feet²
