Ashik claims that the graph on the right is the correct interpretation of the scatterplot, but his friend Shelby claims that the graph on the left is correct.
Shelby’s Graph Ashik’s Graph
A graph titled Shelby's Graph has points that form a curved line. A line with negative slope is drawn. A graph titled Ashik's Graph has points that form a curved line. A curved line is drawn to connect the points.
Who is correct and why?
Shelby is correct because the line of best fit has a negative slope and the trend shows a decrease in y values as the x values increase.
Shelby is correct because the line of best fit matches the points as closely as possible with a weak correlation.
Ashik is correct because the points are a strong correlation to this nonlinear association.
Ashik is correct because points with a weak correlation can never have linear association.

Slope- intercept equation from a graph
Find the equation of the line
Answers
We can find the slope using any two points on the line. Readily identifiable are the points (2, 0) and (0, 3), from which we can find the slope:
[tex]\text{slope} = m=\frac{y_2-y_1}{x_2-x_1} \\ m = \frac{3-0}{0-2} = -\frac{3}{2}.[/tex]
The y-intercept is the y value when x = 0, which we already know is 3. So, the slope-intercept equation of this line is:
[tex]y=-\frac{3}{2}x+3.[/tex]

The perimeter of the triangle below is 75 m. Determine the measure of each side of the triangle
Answers
Step-by-step explanation:
The perimeter is the sum of all sides.
AB+AC+CB=75
(2x-9) + (2x+3) + (3x+4) = 75
Combine like terms:
(2x+2x+3x) + (-9+3+4) = 75
7x - 2 = 75
7x = 77
x=11
Replace 'x' with '11' in the above equations to find that:
AB = 2(11) - 9 = 22 - 9 = 13 m
AC = 2(11) + 3 = 22 + 3 = 25 m
CB = 3(11) + 4 = 33 + 4 = 37 m
13 + 25 + 37 = 75 m

Answer:
Volume of given figure = 113.12 cm²
Step-by-step explanation:
Given:
Radius of cylinder = 4/2 = 2cm
Radius of cone = 4/2 = 2 cm
Height of cylinder = 7 cm
Height of cone = 6 cm
Find:
Volume of given figure
Computation:
Volume of given figure = Volume of cylinder + Volume of cone
Volume of given figure = πr²h + (1/3)πr²h
Volume of given figure = (22/7)(2)²(7) + (1/3)(22/7)(2)²(6)
Volume of given figure = (22/7)(4)(7) + (1/3)(22/7)(4)(6)
Volume of given figure = (22)(4) + (22/7)(4)(2)
Volume of given figure = 88 + 25.14
Volume of given figure = 113.12 cm²

Maya is building a sandbox that is 48 inches wide. The length of the sandbox is four times the wldth of the sandbox. What is the perimeter of the sandbox?
Answers
Answer: 480 in.
Step-by-step explanation:
Given
The width of the sandbox is 48 in.
The length of the sandbox is four times the width
[tex]\therefore L=4\times 48=192\ in.[/tex]
Perimeter is the sum of the sides of the shape
The perimeter of the box is
[tex]P=2[48+192]=480\ in.[/tex]
Answer:
the perimeter of the sandbox is 480 inches
Step-by-step explanation:
The computation of the perimeter of the sandbox is shown below:
Since the width is 48 inches
And, the length would be four times the width i.e.
= 4 × 48
= 192 inches
Now the perimeter of the sandbox is
= 2( length + width)
= 2 (192 inches + 48 inches)
= 480 inches
Hence, the perimeter of the sandbox is 480 inches

Find Tan A if Cos2A = 1/2
Answers
Answer:
tan A = ± 1/√3 or ± 0.58
Step-by-step explanation:
2 ways to solve this question.
1. cos 2A = 1/2 2A = 60° or 300° or 420° or ....
A = 30° or 150° or 210° ....
tan A = tan 30° or tan 150° or ... = ± 1/√3
2. cos 2A = 2 cos²A - 1 1/2 = 2 cos²A - 1 cos²A = 3/4
cos 2A = 1 - 2 sin²A 1/2 = 1 - 2 sin²A sin²A = 1/4
tan²A = sin²a/cos²A = (1/4) / (3/4) = 1/3
tan A = ± 1/√3 or ± 0.58
2. How many distinguishable permutations are possible with all the
letters of the word ELLIPSES?
Answers
Answer:
5040
Step-by-step explanation:
This problem is about indistinguishable permutation. We have indistinguishable objects, in this case, these are the letter of the word ELLIPSES. The permutations for the word ELLIPSES is the same when you swap the places of the Ls. We need to not count them to avoid double counting.
We first count how many letters we have on the word, and then count the repeating letters.
ELLIPSES has 8 letters, 2 Es, 2Ls, and 2S.
The formula for indistinguishable permutation is
where n is the total number of objects and are the number of indistinguishable objects.
We have 2Es, 2Ls, and 2S; the formula then becomes:
Simplifying gives us
There are 5,040 distinguishable permutations of the word ELLIPSES.

The total 5040 distinguishable permutations are possible with all the letters of the word ELLIPSES.
The given word is ELLIPSES.
It is required to find total distinguishable permutations that are possible with the above word.
What is permutation?A permutation can be defined as the number of ways a set can be arranged.
Permutation formula as below:
[tex]P=\frac{n!}{p!q!r!...}[/tex]
Where n = Total number of objects.
p,q,r...= the number of indistinguishable objects.
Here total number of letters in the word n = 8
and ELLIPSES have 2Es, 2Ls, and 2S; the formula then becomes:
[tex]=\frac{8!}{2!2!2!}[/tex]
[tex]=\frac{8*7*6*5*4*3*2*1}{2*1*2*1*2*1}[/tex]
[tex]=5040[/tex]
Thus, the total 5040 distinguishable permutations are possible with all the letters of the word ELLIPSES.
