Step-by-step explanation:

By my math that should is definitely correct. your welcome

Given:

The data set is:

14, 15, 3, 15, 14, 14, 18, 15, 8, 16

To find:

The mean, median and mode of the given data set.

Solution:

We have,

14, 15, 3, 15, 14, 14, 18, 15, 8, 16

Arrange the data values in ascending order.

3, 8, 14, 14, 14, 15, 15, 15, 16, 18

Mean of the data set is:

[tex]Mean=\dfrac{\text{Sum of all observations}}{\text{Number of observation}}[/tex]

[tex]Mean=\dfrac{3+8+14+14+14+15+15+15+16+18}{10}[/tex]

[tex]Mean=\dfrac{132}{10}[/tex]

[tex]Mean=13.2[/tex]

The number of observation is 10 which is an even number. So, the median of the data set is:

[tex]Median=\dfrac{(\dfrac{n}{2})\text{th term}+(\dfrac{n}{2}+1)\text{th term}}{2}[/tex]

[tex]Median=\dfrac{(\dfrac{10}{2})\text{th term}+(\dfrac{10}{2}+1)\text{th term}}{2}[/tex]

[tex]Median=\dfrac{5\text{th term}+6\text{th term}}{2}[/tex]

[tex]Median=\dfrac{14+15}{2}[/tex]

[tex]Median=\dfrac{29}{2}[/tex]

[tex]Median=14.5[/tex]

Mode is the most frequent value of the data set.

In the given data set the highest frequency is 3 because 14 and 15 occurs three times.

So, the mode of the given data set is 14 and`15.

Therefore, the mean is 13.2, median is 14.5 and mode is 14 and 15.

Answer:

[tex]84^{\circ}[/tex]

Step-by-step explanation:

The measure of an inscribed angle is exactly half the measure of the arc it forms. Thus, we have the following equation:

[tex]2(7x-7)=9x+21[/tex]

Solving, we get:

[tex]2(7x-7)=9x+21,\\14x-14=9x+21,\\5x=35,\\x=7[/tex]

Plugging in [tex]x=7[/tex] into [tex]9x+21[/tex]:

[tex]\widehat{DG}=9(7)+21,\\\widehat{DG}=63+21,\\\widehat{DG}=\boxed{84^{\circ}}[/tex]

Answer:

bread $2.5   milk  $3.95

Step-by-step explanation:

b=bread    m= milk

3b +3m = 19.35

4b+2m= 17.90

 Multiply the first by  (-2)

 Multiply the second  by 3

    Then add both

              -6b -6m = -38.7

               12b+6m=53.7

     (when you add both  6m is cancelled)

           6b = 15

         b=  2.5     (BREAD $2.5)

4(2.5) = 10

 10+ 2m = 17.90

2m = 7.90

m= 3.95   (MILK $3.95)

Answer:

1.   5 in.

2.   12 in.

Answer: 12

Answer:

Whats the question, respond in comments.

Answer:

Length = 12 feet, Width = 10 feet

Step-by-step explanation:

Let the length of the bedroom be 'x' ft and the width of the bedroom be 'y' ft.

We know that the perimeter of a rectangle is given by,

P=2(length+width)

P=2(x+y)

It is given that, the length of the bedroom is 2 more than the width, so,

x=y+2

Putting the values in the equation of perimeter we get,

44=2((y+2)+y)

44=2(2y+2)

44/2 =2y+2

22=2y+2

2y=22−2

y= 20/2 =10

Therefore, x=y+2=10+2=12

Hence, the length of the bedroom is 12 feet and the width of the bedroom is 10 feet.

Answer:

44x²y³

Step-by-step explanation:

don't see options for answers but the perimeter would be:

2(3x²y³) + 2(4x²·2y³)

= 6x²·2y³ + 8x²·4y³

= 12x²y³ + 32x²y³

= 44x²y³

For some reason, my explination isn't formatting properly, hope this helped

Answer:

Step-by-step explanation:

The angle is 60 degrees so the triangle is half of an equilateral triangle

so y is half of the hypotenuse:

y = 16/2 = 8

x = √16^2 - 8^2 = √256 - 64 = √192  = 8√3

Answer:

$49,057.50

Step-by-step explanation:

To find how much a percent is of a number you multiply that number and that percent then add the two

SO.... 46,500x5.5% is 2557.50 and then you add the 2 so 46,500 + 2557.50= 49,057.50 hope this helps
