Answer:

Mean = 33.7

Median = 34.5

Mode = 34

Range = 33

After adding 26....

mean decreases by 0.7

median decreases by 0.5

mode is 34

range is 33

Step-by-step explanation:

mean = sum of all the data values/number of data values

= (18 + 19 + 20  + 34 + 34 + 35 + 37 + 42 + 47 + 51)/10
= 337/10
= 33.7

To find median arrange the values in increasing order, find the mid value

If the number of data points is even, find the average of the mid 2 data values

Arranging data values we get:
18, 19, 20, 34, 34, 35, 37, 42, 47, 51

Since there are 10 data values, take the average of the middle two:
(34 + 35)/2 = 34.5

The mode is the value that occurs most often. We see that there are two instances of 34 whereas the other values appear only once

Mode = 34

The range is highest - lowest = 51 - 18 = 33

After we add 26, we get the following data set arranged

18, 19, 20, 26, 34, 34, 35, 37, 42, 47, 51

we can calculate the stats using the same technique as above

We get the following values

mean = )(18 + 19 + 20 + 26 + 34 + 34 + 35 + 37 + 42 + 47 + 51)/11
= 33  

median = 34

mode = 34

range = 51-18 = 33

To find the decrease in mean and median subtract from the first set of values

Answer:

158 in

Step-by-step explanation:

front/back faces: 8 * 3 = 24in

side faces: 8 * 5 = 40in

top/bottom faces: 3 * 5 = 15in

2 * (24 + 40 + 15) = 158in

Answer:

The height is 5 units

Step-by-step explanation:

The area of a triangle is

A = 1/2 bh where b is the base and h is the height

30 = 1/2 (12) h

30 = 6h

Divide each side by 6

30/6 = 6h/6

5 = h

The height is 5 units

Answer:

D is the right choice and no you cannot fit the pizza inside the box.

Step-by-step explanation:

D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.

Answer:

I believe the answer is D.

Step-by-step explanation:

The dimensions of the rectangle ABCD is 24 x 16

The perimeter P of a rectangle is given by the formula, P=2 ( L + W) , where L is the length and W is the width of the rectangle.

Perimeter P of rectangle = 2 ( Length + Width )

Given data ,

Let the dimensions of the rectangle be represented as L x W

where L and W are the length and width of the rectangle

The perimeter of the rectangle P = 80

Now , measure of side E F of triangle is given by the Pythagoras Theorem

And , E F = √ ( A F )² - ( E A )²

On simplifying the equation , we get

The measure of side E F = √ ( 625 - 400 )

The measure of side E F = √225 = 15

Now ,

The measure of side EC of triangle is given by the Pythagoras Theorem

And , EC = √ ( E F )² - ( C F )²

On simplifying the equation , we get

The measure of side E C = √ ( 15 )² - ( 9 )²

The measure of side E C = √ ( 225 - 91 )

The measure of side E C = √144

The measure of side E C = 12

So , the length of the rectangle B C = E B + B C = 12 + 12

The length of the rectangle B C = 24

The width of the rectangle is A B = W

Perimeter P of rectangle = 2 ( Length + Width )

Substituting the values in the equation , we get

80 = 2 ( 24 + W )

Divide by 2 on both sides of the equation , we get

24 + W = 40

Subtracting 24 on both sides of the equation , we get

W = 16

Hence , the dimensions of the rectangle is 24 x 16

Answer:

area = 85.84 ft²

Step-by-step explanation:

large rectangle  area = 6 x 12 = 72 ft²

2 triangles area = 2(4 x 3.46 x 0.5) = 13.84 ft²

72 + 13.84 = 85.84 ft²

Answer:

the numbers 2 and 6 are both the modes.

Step-by-step explanation:

the mode is the number that appears the most. if there are two numbers that appear most often (and the same number of times) then the data has two modes.

the nubers 2 and 6 were repeated 4 times. causing them to be the modes of the data set :)

Answer:

6 and 2 is your answer

Step-by-step explanation:

1. You have the numbers 2, 6, 8, 3, 4, 6, 2, 6, 8, 5, 6, 2, 7, 8, 4, 3, 2, 7, 3, 4

2. Count how much each number occurs.

2 occurs 4 times

6 occurs 4 times

8 occurs 3 times

3 occurs 3 times

4 occurs 3 times

5 occurs once

And 7 occurs twice

3. See which number occured the most.

Answer:

$44

Step-by-step explanation:

Let the total amount of money be represented by Y

Amount spent on fresh food =

\( \frac{4}{7} \times y\)

Remainder =

\(y - \frac{4}{7}y = \frac{3}{7} y\)

Amount spent on frozen foods = two-thirds of remainder = $22

\( = \frac{2}{3} \times \frac{3}{7} y = \frac{2}{7} y\)

\(\frac{2}{7} y = 22 \\ y = 22 \times \frac{7}{2} \\ y = 77\)

The total amount for grocery shopping is $77

Therefore, Brittany spent $44 on fresh foods

\( = \frac{4}{7} \times 77 \\ = 4 \times 11 \\ = 44\)
