Answer:

5 is the median of this data set.

Step-by-step explanation:

Median is the number in the middle. When the data is ordered from the least to the greatest (ascending order). If the two middle values, find the mean of two middle values.

Now we arrange this data in ascending order

2, 3, 3, 3, 4, 4, 5, 5, 5, <u>5, 5</u>, 6, 7, 8, 8, 9, 9, 9, 10, 10

We find two numbers in the middle, we add them and divide with 2.

= (5 + 5) / 2

= 10 / 2 = 5

5 is the median of this data set.

Answer:

Step-by-step explanation: Each Notebook Cost $4

If haley Bought 1 Backpack That Was $36 Dollars, Subtract The Number 36 From The Total Amount She Paid For Everything. 48-36 = 12.

If She Bough 3 Notebooks, Divide How Much She Paid By How Many Notebooks She Bought.

12 Divided By 3 Is 4

I need help solving this step by step please.

babunello [35]

Answer:

Yes, i believe that the generalization about the measure of a point angle of a star polygon is true.

First we find sum of interior angle of an n-sided star polygon.

number of triangle in a polygon = n - 2

sum of interior angle of a triangle = 180°

sum of interior angle of an n-sided star polygon = ( n - 2 ) × 180°

To find measure of a point angle, we use:

$\frac{|n-2(d)|}{n}$ × 180°

To find a point angle we eliminate density by multiplying d by 2 in the formula for finding number of triangle, divide the whole by total number of sides and then multiply by the sum of interior angle of triangle(180°).

Since all the angle of a regular star polygon are equal, we can calculate each pointy interior angle of a regular star polygon using the formula given below:

$\frac{|n-2(d)|}{n}$ × 180°

A net and 4 figures are shown. Which figure shown can be formed from the net. ( input the number only) please answer quick and e

AfilCa [17]

A net is pretty much a three dimensional shape unfolded into a flat construction. Imagine cutting the edges of a box and unfolding it so you can lay it flat on the ground. That would form a net for the 3D shape of the box.
In this case, 1 and 2 obviously aren't right since they would both involve triangles in their net. 3 is close, but the parts of the net wouldn't be completely equal. Therefore it has to be 4, the cube.

The sum of the consecutive numbers is 111. What is the smallest of the three numbers?

sammy [17]

Let
x = first consecutive number
x + 1 = second consecutive number
x + 2 = third consecutive number

The sum of these numbers are 111.
x + x + 1 + x + 2 = 111
3x = 111 - 1 - 2
3x = 108
x = 36

Therefore, the smallest number is 36 because other numbers are 37 and 38.

Answer:

(1/2)x+(1/4)=x

x=0.5

3x+3=2(x+7)

x=11

2(x-5)+7=x+8

x=11

0.8x+5=0.2(40-x)

x=3

5(x-1)-6x=-11x

x=0.5

6(x+2)-x=4(x+4)+7

x=11

(1/2)(x+8)+(3/2)x=10

x=3

Step-by-step explanation:

(1/2)x+(1/4)=x

x-0.5x=0.25

0.5x=0.25

x=0.5

3x+3=2(x+7)

3x+3=2x+14

3x-2x=14-3

x=11

2(x-5)+7=x+8

2x-10+7=x+8

2x-x=8+10-7

x=11

0.8x+5=0.2(40-x)

0.8x+5=8-0.2x

0.8x+0.2x=8-5

x=3

5(x-1)-6x=-11x

5x-5-6x=-11x

11x-x=5

10x=5

x=0.5

6(x+2)-x=4(x+4)+7

6x+12-x=4x+16+7

6x-4x-x=16+7-12

x=11

(1/2)(x+8)+(3/2)x=10

0.5x+4+1.5x=10

2x=6

x=3
