Answer:The mean absolute deviation (MAD) of the number of pages in the 5 books Rori read =24
Step-by-step explanation:
To find the the mean absolute deviation (MAD,we start firt by
Getting the mean of all values
Mean =120, 106, 94, 100, 180/5 =600/5=120
Next we subtract the mean value from each value which is called distance
120 -120 = 0
106 -120 = -14
94 -120= -26
100 -120=-20
180 -120=60
Thirldly, we find the mean of the distances ignoring the negative signs
0+14+26+20+60 / 5 = 120/5=24
Allison measures some artwork for framing. The first picture is 9 3/4 inches long and the second is 7 1/4 inches long. What is the difference in length of the art?
Answer:
2 2/4
Step-by-step explanation:
Since the first picture is 9 3/4 and the second is 7 1/4. You have to subtract to find the answer.
Ex:
5 - 1 2/4 = ?
First lets turn five in to a fraction 5 -> 5/1
Now lets turn one and a half into an improper fraction 1 2/4 -> 6/4
We can now subtract easily!

Lu is making a quilt that is 20 squares wide and has 15 rows. The border of the quilt is made by using each toy design equally as often. There are a total of 6 toy designs. Each square can hold one design. How many of each design does she use for the border?
Answer:
Out of 6 designs 4 designs will have 12 repetitions and 2 designs will have 11 repetitions.
Or
On the average each design will be repeated 11.67 times.
Step-by-step explanation:
HEre the width = 20 and length = 15
The perimeter = 2(l+b)
= 2( 20+ 15) = 70
The border of the quilt has 70 squares. Each square can have 1 design and there are 6 designs
Number of repetitions for each design = 70/6= 11. 67
6 designs can have 11 repetitions for 66 boxes= 6 *11= 66
4 squares will be left out. 70-66= 4
4 design can have additional repetition.
Meaning out of 6 designs 4 designs will have 12 repetitions and 2 designs will have 11 repetitions.
Or
On the average each design will be repeated 11.67 times.

Find the equation for the
following parabola.
Vertex (2, 3)
Focus (7,3)
Answer:
b
Step-by-step explanation:
formula
(y-k)^2 = 4a(x-h) horizontal parabol
a = 7 - 2 =5
(y-k)^2 = 4*5*(x-h)
(y-k)^2 = 20(x-h)
k=3 , h=2
(y-3)^2 = 4a(x-2)

Solve negative 2 x plus 3 is greater than or equal to negative 3
Answer:equal
Step-by-step explanation:
Answer:
x is less than or equal to 3
Step-by-step explanation:
subtract three from both sides which will give you 2x is greater than or equal to -6. then divide by -2 on both sides to isolate x (dividing by a negative number flips the sign and a negative divided by a negative equals a positive) so then you get x is less than or equal to 3

If you have a new deck of shuffled cards, what is the probability you will choose an ace? (52 cards, no jokers) A) 1 13 B) 1 2 C) 1 4 D) 1 6
Answer:
B 1/2
Step-by-step explanation:
I looked it up.
But I think it'd be C because there would be 4 aces in the deck, and C has 1/4
Answer: 1/13 is the correct answer.
Step-by-step explanation: You put the total amount of aces, which is four, on the top part of your fraction and the total number of 52 cards on the bottom of your fraction. Since four will divide into both numbers, you simplify 4/52 to get 1/13. 4 divided by four is one. 52 divided by 4 is 13. That is how you get your 1/13 from 4/52. Answer was confirmed correct on the test I took. I hope this helps you! Thanks!

What is the approximate volume of the cone below?
7 cm
10 cm
Answer:
183
Step-by-step explanation:
The volume of the cone formula is : [tex]= \pi r^{2} \frac{h}{3}[/tex]
[tex]radius = 10 / 2 = 5[/tex][tex]v= \pi 5^{2} 7/3[/tex]
[tex]\pi 25 * 7/3= \pi * 58.33= 183. 26[/tex]

Which of the following are solutions to 2x^2-8x-90
Answer:
2(x-9)(x+5)
Step-by-step explanation:
In the following diagram, medians AD and BE intersect at F. Which of the following segments would not be true
1) ECD~ACB
2) EF= 1/2EB
3) ED||AB
4) the median drawn from C would pass through F
The segment that is false is (2) EF= 1/2EB
The median lines of a triangle always meet at a point.
This means that the line from point C is true (option 4 is true)
The median divides the side lengths of the triangle into equal segments.
However, the centroid at point F do not divide line EB into equal segments
This means that:
The equation EF= 1/2EB is false
Hence, the segment that is false is (2) EF= 1/2EB

can you say a triangle with equal angles of 60 is equilateral
Answer:
Not really
Step-by-step explanation:
NOT NECESSARILY would a triangle be equilateral if one of its angles is 60 degrees. To be an equilateral triangle (a triangle in which all 3 sides have the same length), all 3 angles of the triangle would have to be 60°-angles; however, the triangle could be a 30°-60°-90° right triangle in which the side opposite the 30 degree angle is one-half as long as the hypotenuse, and the length of the side opposite the 60 degree angle is √3/2 as long as the hypotenuse. Another of possibly many examples would be a triangle with angles of 60°, 40°, and 80° which has opposite sides of lengths 2, 1.4845 (rounded to 4 decimal places), and 2.2743 (rounded to 4 decimal places), respectively, the last two of which were determined by using the Law of Sines: "In any triangle ABC, having sides of length a, b, and c, the following relationships are true: a/sin A = b/sin B = c/sin C."¹
Step-by-step explanation:
A triangle with three equal interior angles is called an equiangular triangle. In an equiangular triangle has three. equal sides, and it is the same as an equilateral triangle.
