Answer:
156.9
Step-by-step explanation:
∠x=4(∠y)
Angles in a triangle add to 180:
∠x+∠y+90=180
4(∠y)+∠y=90
5(∠y)=90
∠y=18
The left side of the parallelogram is opposite ∠y, which we know, and we know the adjacent (marked as 57) so we can use tan:
tanA=opposite/adjacent
tan18=(side)/57
side=18.5204226853
Similarly, we can find the base of the shape using cos:
cosA=adjacent/hypotenuse
cos18=57/(base)
base=59.9333467816
Perimeter = 2(side)+2(base)
=2(18.5204226853)+2(59.9333467816)
=37.0408453706+119.866693563
=156.907538934

Answer:
33 ft²
Step-by-step explanation:
The area of the outdoor carpet = area of trapezoid + area of rectangle + area of triangle
✔️Area of trapezoid = ½(a + b)h
Where,
a = 6 ft
b = 3 ft
h = 11 - 9 = 2 ft
Area of trapezoid = ½(6 + 3)*2 = 9 ft²
✔️Area of rectangle = L*W = 7 *3 = 21 ft²
✔️Area of triangle = ½bh
b = 2 ft
h = 3 ft
Area = ½*2*3 = 3 ft²
✅Area of the outdoor carpet = 9 + 21 + 3 = 33 ft²

Chauncey is building a storage bench for his son’s playroom. The storage bench will fit into the corner and against two walls to form a triangle. Chauncey wants to buy a triangular shaped cover for the bench.
Formula for Area of Triangle:
A = ½ x b x h
(the photo is below)
If the base of the storage bench is 2 ½ ft. and the height along one side of the wall is 4 ½ ft. What is the area of the triangular cover?
Answers
Answer:
2.5 times 4.5 times .5 = 5.625 ft squared
Step-by-step explanation:
Lets look at our Formula
.5 times base of triangle (b) times height of triangle (h)
Based on the photo, the height is 4.5 feet and the base is 2.5 feet.
4.5 times 2.5 times .5 (the 1/2 in the formula) = 5.625 ft squared.
Remember that it is 1/2 times the base and height, b/c triangle is half of square. Ft squared because ft times ft equals ft squared

2) Ms. Smith, a math teacher, recently gave a mathematics quiz in her class. The ten quiz scores were: 89 87 93 90 12 91 88 87 83 91
a) Based on the test scores above, would you say the class did well? Why or why not?
b) If you were Ms. Smith, which average would you use to describe the data: mean, median, or mode?
Answers
Answer:
Step-by-step explanation:
The average is 81 a low B, but if you throw out the low score it rises to 88.8, a high B.
I would use the median 88, 89 since it is higher and is a more accurate representation of the majority of the class
A) Yes, we can say that the class did well.
B)I would choose median to describe the data.
How to find mean, median and mode?
Mean simply means average of the data given, Here,
[tex]Mean=\dfrac{89+87+93+90+12+91+88+87+83+91}{10} =80.9[/tex]
Median is the value of data set (when arranged in ascending order) that divides it into two sets and is often called the middle number. When no. pf values in data set is even, the median is N/2.
Here,
[tex]Median=\dfrac{10}{2} ^{th}=5^{th} term=88[/tex] (data taken in ascending order)
Mode is the value which has largest frequency among the all the other values.
Here, Mode is 87 and 91.
A) The class did well if we consider the data from point of view of its median and mode, but the average value is a bit low as we have a drastically low value that is 12.
B) I would describe the data by median because the class mean is very low and as there are 2 mode values, it is not the best representation of the score. The median of the set is a high and singleton value, therefore the most accurate measure of central tendency would be median.

find a20 of a geometric sequence of the first few terms of the sequence given by -1/2;1/4;-1/8;1/16
Answers
Answer:
[tex]a_{20} = 1/1048576[/tex]
Step-by-step explanation:
Given
[tex]Sequence: -1/2;1/4;-1/8;1/16[/tex]
Required
Determine [tex]a_{20[/tex]
Since it is a geometric sequence, first we need to calculate the common ratio (r)
[tex]r = \frac{a_2}{a_1}[/tex]
From the sequence:
[tex]a_2 = 1/4[/tex]
[tex]a_1 = -1/2[/tex]
[tex]a_1[/tex] is the same as [tex]a[/tex]
So:
[tex]r = \frac{a_2}{a_1}[/tex]
[tex]r = \frac{1/4}{-1/2}[/tex]
[tex]r = -1/2[/tex]
[tex]a_{20[/tex] is then calculated as:
[tex]a_n = ar^{n-1}[/tex]
Where
[tex]n = 20[/tex]
[tex]a_{20} = ar^{20-1}[/tex]
[tex]a_{20} = ar^{19}[/tex]
[tex]a_{20} = (-1/2) * (-1/2)^{19}[/tex]
Apply law of indices
[tex]a_{20} = (-1/2)^{1+19}[/tex]
[tex]a_{20} = (-1/2)^{20}[/tex]
Evaluate the exponent
[tex]a_{20} = 1/1048576[/tex]

Answer:
3. X = (-4, -5), Y = (0, -3), Z = (-1, -7)
4. Refer back to my explanation.
5. a. Refer back to my explanation.
5. b. 28 units^2; please solve for the other rectangle.
5. c. No, because translation means moving the figure, not changing the shape or size.
Step-by-step explanation:
Warning in advance: the picture is very blurry when looking at the numbers on the graph so I have tried my best to decipher them.
3.
First, write down the ordered pairs for X, Y, and Z.
X = (-1, 4)
Y = (3, 6)
Z = (2, 2)
Note that horizontal movement (moving left or right) affects only the x coordinate. If you are moving to the left, you will subtract from the x coordinate. If you are moving to the right, you will add to the x coordinate.
Vertical movement (moving up or down) affects only the y coordinate. If you are moving up, you will add to the y coordinate. If you are moving down, you will subtract from the y coordinate.
Apply this concept to the ordered pairs:
Moving left = subtraction from x coordinate
Moving down = subtraction from y coordinate
X2 = (-1 - 3, 4 - 9) = (-4, -5)
Y2 = (3 - 3, 6 - 9) = (0, -3)
Z2 = (2 - 3, 2 - 9) = (-1, -7)
Your new image should have X at (-4, -5), Y at (0, -3), and Z at (-1, -7).
4.
After reading the concepts and seeing my explanation and demonstration, please try number 4 on your own. If you have any questions, feel free to ask me for help.
5. a.
The same goes for this problem since it is the same concept.
5. b.
To find the area of a rectangle, use the equation length × width, also known as l × w. In order to figure out what the length and width are equal to, count the units on the graph. JK is 7 units wide. Since this is a rectangle, ML will be the same width, 7 units. KL is 4 units long so JM will also be 4 units long. Now that we know the number of units, we can plug the numbers into the formula:
4 units × 7 units = 28 units^2
The question asks to solve for the area of each rectangle so please try the same for the rectangle you create from problem 5. a.
5. c.
The area of a figure will not change after translation because translation does not affect the figure's size or shape. If the figure is only moved, then no part of its area is changed so no, the area of a figure will not change.
The length of a rectangle is 5 less than twice the width, and the area of the rectangle is 52 ft^2. Find the dimensions of the rectangle.
Answers
9514 1404 393
Answer:
6.5 ft wide by 8 ft long
Step-by-step explanation:
We can let x represent the width of the rectangle. Then the length is ...
L = 2x -5
and the area is ...
A = LW = (2x -5)(x) = 52
2x² -5x -52 = 0 . . . . . put in standard form
(2x -13)(x +4) = 0 . . . . factor
x = 6.5, -4 . . . . . . . . . . values that make the factors zero
The length is then ...
L = A/W = 52/6.5 = 8
or
L = 2W -5 = 2(6.5) -5 = 13 -5 = 8
The rectangle is 6.5 feet wide and 8 feet long.

The 95% Confidence Interval is ($, $ )
Answer:
at 95%, confidence interval is ( $43312, $54288 )
Step-by-step explanation:
Given the data in the question;
sample size n = 36
mean x' = 48,800
standard deviation σ = 16,800
at 95% confidence level;
∝ = 1 - 95% = 1 - 0.95 = 0.05
∝/2 = 0.05 / 2 = 0.025
z critical value, [tex]Z_{\alpha/2[/tex] = 1.96
now, confidence interval for population mean is given by the formula
x' ± [tex]Z_{\alpha/2[/tex]( σ/√n )
so we substitute
⇒ 48800 ± 1.96( 16800/√36 )
⇒ 48800 ± 1.96( 2800 )
⇒ 48800 ± 5488
⇒ 48800 - 5488, 48800 + 5488
⇒ ( 43312, 54288 )
Therefore, at 95%, confidence interval is ( $43312, $54288 )
