4, 3, 4, 5, 6, 6, 8, 4

Part A: What is the mean of the data? Show your work. (4 points)

Part B: Use your answer from Part A to calculate the mean absolute deviation for the data. Show your work. (6 points)

Answers

Answer 1

Part A:

The mean of the data is 5 because you add all the numbers otgether then divided it by 8 (the number of classmates). 4 + 3 + 4 + 5 + 6 + 6 + 8 + 4 = 40 then divided by 8 is 5.

Answer 2
Answer is 5
Hope this helped

Answers

Answer:

it says there are only 10, not 20?

Step-by-step explanation:

Given that the base of the triangle is 12ft, and the hypotenuse is 37ft, the missing side is 35ft.
Since L is a square, all the sides will be 35ft
Area = length squared
Area of square L = 35ft^2 or option b

Answer:

4) 10.5 m.  5) 7 1/3   6)6m

Step-by-step explanation:

5 might be inaccurate (as i am doing mental math) but 4 and 6 are definently right :)

4) 7 times 1 1/2 = 7 times 1 = 7
7 times 1/2 equals 7/2 or 3 1/2
add 7 and 3 1/2
answer is 10 1/2cm

5) 5.5 divided by 1.5
1.5 times 3 equals 4.5
1 divided by 1.5 equals .6
3 plus .6 equals 3.6
3.6 times 2 equals 7.2in

6) 9 divided by 3 equals 3
so 3 times 2 equals 6m

Help me with math please
A cone has a slant height of 15 cm and a height of 12 cm.
What is the radius of the cone?

cm.
What is the volume of the cone?

cubic centimeters.

Answers

Answer:

The answer to your question is 9 cm

Step-by-step explanation:

Data

slant height = 15 cm

height = 12 cm

radius = ?

Process

To solve this problem, use the Pythagorean theorem. The slant height is the hypotenuse, the height is the long leg and the radius is the short leg.

            c² = a² + b²

          slant height² = height² + radius²

-Solve for radius

          radius² = slant height² - height²

-Substitution

          radius² = 15² - 12²

-Simplification

           radius² = 225 - 144

           radius² = 81

-Result

           radius = 9 cm

Answer:it would be C.

Step-by-step explanation:

6-(-6)=12 and 5-(-3)=8, so if you put it in the fraction, it would end up as 3/2.


3-(-3)=6 and 3-(-1)=4, and 6/4 simplified is 3/2. If both slopes are 3/2, then they would be parallel, showing that the two lines have the same slope. Another way to prove is that 3/2=3/2 is true

A spinner with four sections is spun 30 times.
Color Number of times
Red 7
Yellow 8
Blue 6
Green 9

Based on these results, what is the experimental probability that the next time the spinner is spun, it lands on green?
A. 1/5
B. 3/10
C. 4/15
D. 7/30

Answers

Answer:

3 / 10

Step-by-step explanation:

Total = 30 times

n ( T ) = 30

Green = 9

n ( G ) = 9

To find : Probability of Green [ P ( G ) ]

Formula : -

P ( G ) = n ( G ) / n ( T )

P ( G ) = 9 / 30

9 = 3 x 3

30 = 3 x 10

P ( G ) = ( 3 x 3 ) / ( 3 x 10 )

P ( G ) = 3 / 10

Hence,

the experimental probability that the next time the spinner is spun, it lands on green is 3 / 10.

B
If it landed on green 9/30 times that is the ratio.
3/10= 9/30

Express x in terms of y! Find the value of x when y =5
2(x - 3)/y =5​

Answers

Hey there!

2(x - 3) / y = 5

2(x - 3) / 5 = 5

2(x) + 2(-3) / 5 = 5

(2x - 6) 5 = 5

MULTPLY 5 to BOTH SIDES

(2x - 6)/5 * 5 = 5 * 5

SIMPLIFY IT!
2x - 6 = 5 * 5

2x - 6 = 25

ADD 6 to BOTH SIDES

2x - 6 + 6 = 25 + 6

SIMPLIFY IT!
2x = 25 + 6

2x = 31

DIVIDE 2 to BOTH SIDES

2x/2 = 31/2

SIMPLIFY IT!

x = 31/2

x = 15 1/2


Therefore, the answer should be:

x = 15 1/2


Good luck on your assignment & enjoy your day!

The graph shows two lines, A and B.

Part A: How many solutions does the pair of equations for lines A and B have? Explain your answer.

Part B: What is the solution to the equations of lines A and B? Explain your answer

Answers

Answer:

A: 1 solution

B: (4,4) is the solution

Step-by-step explanation:

They have different slopes so they're already different equations and because of that, they can only have one solution.

The intersection of the two lines is the solution since those coordinates satisfy both equations.

Answer:

Part A

The solutions of a graphed pair of equations are the points of intersection - the points on the graph where the two lines cross each other.  At this point, when inputting the same x-value into the 2 equations, the resulting y-values will also be the same.

Therefore, from inspection of the graph, there is one point of intersection, and so one solution.

The name for a system that has one solution and intersects at one point is Consistent Independent

Part B

From inspection of the graph, the point of intersection is (4, 4).

Therefore, the solution to the equations of line A and B is (4, 4).

Proof

Equation of line B:  y = xEquation of line A:  y = -0.5x + 6

Using substitution:

⇒ x = -0.5x + 6

⇒ 1.5x = 6

⇒ x = 4

Substituting the found value of x into one of the equations to find y:

⇒ y = 4

Therefore, the solution is (4, 4)
