Some students recorded how many minutes they spent on the phone in one day. They put the results in a Stem-and-Leaf Plot.
What is the mean number of minutes spent on the phone?
Answers
Explanation:
The data from the stem-and-leaf plot is:
10,
24,25,26,
30,30,32,33,
40,45,46
Add up those values
10+24+25+26+30+30+32+33+40+45+46 = 341
Then divide over n = 11 which is the sample size.
341/11 = 31 is the arithmetic mean.
Answer:
341/11 = 31 is the arithmetic mean.

Step-by-step explanation:
You are given a triangle with side lengths of 6, 9, and 12. Is the triangle a right triangle? How do you know?
Answers
Answer:
No, it's not
Step-by-step explanation:
You choose the longest side which is 12 and apply the theory of phitagors
The longest side which is the hypotenuse in a right triangle = square root the square sum for each side
So to be a right triangle it should be
\( \sqrt{ {9}^{2} + {6}^{2} } = 10.8 \: \: that \: doesnt \: equal \: 12\)
So it's not a right triangle.
Look at the famous right triangle whose side are 5(hypotenuse), 4, 3
\( \sqrt{ {4}^{2} + {3}^{2} } = 5\)
So it's a right triangle
Right triangle lengths can be checked by the Pythagorean theorem.
This states that a^2+b^2=c^2
a and b are the shorter side lengths, and they form the right angle. c is the hypotenuse, and is the longest length.
Input the values to check if the equation checks out:
6^2+9^2=12^2
36+81=144
117≠144
No, it is not a right triangle. Hope this helps!

2 5/18Step-by-step explanation:
7 2/3 - 3 1/6 - 2 2/9 = Given 7 12/18 - 3 3/18 - 2 4/18 = Bring to common denominator of 18(7 - 3 - 2) + (12 - 3 - 4)/18 = Group integers and fractions2 + 5/18 = Simplify2 5/18 AnswerThe first step is to find a common denominator. (I will be using • to represent multiplication) The lowest common denominator that 3, 6, and 9 share is 18.
3 • 6 = 18
6 • 3 = 18
9 • 2 = 18
To rewrite your numbers using 18 as a denominator, you must multiply the numerator and denominator by the same number.
Since 3 • 6 = 18, 7 2/3 will be rewritten as
7 12/18 (since 2 • 6 = 12) we don’t have to worry about the whole number (7), so leave it as it is.
3 1/6 can be rewritten as
3 3/18, since 6 • 3 = 18 and 3 • 6 = 18
Once again we leave the whole number alone
2 2/9 can be rewritten as
2 4/18, since 9 • 2 = 18 and 2 • 2 = 4
Now we simply subtract our whole numbers and our fractions. Let’s first subtract our whole numbers.
7 - 3 - 2 = 2
Now we can subtract our fractions. Remember that when we subtract fractions, the denominator stays the same. In other words, we only subtract the numerator and ignore the denominator.
12/18 - 3/18 - 4/18 = 5/18
Therefore youre solution is
2 5/18

top of pink cuboid is 2 x 2 which is 4
sides of pink cuboid are 6 x 6 and there are 4 of the same faces so 6 x 6 x 4
green cuboid side is 5 x 4 and there are 2 faces that are similar so 5 x 4 x 2
the other side of the green cuboid is 10 x 4 and there are 2 faces that are similar so 10 x 4 x 2
the bottom and top would be 10 x 5 and there are 2 faces that are similar so 10 x 5 x 2 but a chunk of the top face is being blocked so we have to subtract the amount thats blocking it off so we do( 10 x 5 x 2 ) - ( 2 x 2 ), 2 x 2 is the face blocking it off.
the total then adds up to 364 cm but if that doesnt work then do 364 because it might be trying to count in bottom face of the pink shape

Area of five squares = 1289.09 square units
Perimeter = 194.6 units
Step-by-step explanation:
Area of square and perimeter:
First find the length of each square, then find the area of each square.
To find the area of five squares, add all the area of each square.
Side of square1 = 27 units
\(\sf Side \ of \ square2 = \dfrac{2}{3}*27=2*9 = 18 \ units\\\\Side \ of\ square3= \dfrac{2}{3}*18=2*6=12 \ units\\\\Side \ of \ square4=\dfrac{2}{3}*12=2*4=8 \ units\\\\Side \ of \ square5=\dfrac{2}{3}*8=\dfrac{16}{3}=5.3 \ units\)
Area of square1 = 27*27 = 729 square units
Area of square2 = 18*18 = 324 square units
Area of square3 = 12*12 = 144 square units
Area of square4 = 8*8 = 64 square units
Area of square5 = 5.3*5.3 = 28.09 square units
Area of five squares = 729 + 324 + 144 + 64 +28.09
= 1289.09 square units
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Perimeter of the composite figure = (27 + 27+27+9) + (18+18+6) +(12+12+4) + (8+8+2.7)+ (5.3+5.3+5.3)
= 90 + 42 + 28 + 18.7 + 15.9
= 194.6 units

find the degree of 3m^2·n^4
Answers
Answer:
4
Step-by-step explanation:
The degree of a polynomial is the variable with the highest degree, in this case you have two variables and generally, when you have two variables, especially when they're grouped you would add the degrees So for example: \(xy^3 + x^2y^3\). The first term xy^3 has a degree of 4 because x has a degree of 1 and y has a degree of 3, adding those two becomes 4, the second term has a degree of 5 so the degree of the polynomial is 5. In your example, you provided \(3m^2-n^4\), which you can think of as: \(3m^2n^0 * n^4m^0\). Adding the degrees you get 2 and 4 the highest one is 4, so the degree of the polynomial is 4
Answer:
4
Step-by-step explanation:
Here the exponent of n is 4, which is greater than the exponent of m, which is 2. Thus, the degree of this expression is 4.
