Answer:  mean and  median will lie in the interval 6 -10

Explanation:

mean = \sum_{i=1}^{4} fi*xi/fi

          = (42+64+52+36)/(14+8+4+2)

            =194/28= 6.mean lies in the interval 6-10

for median we have to find n

here n = sum of frequencies /2

n= 28/2=14

so median will lie in the class 6-10

since, it will lie in cumulative frequency of the interval 5-10

so frequency class interval will be one next to cumulative that is 6-10.

The statement that is most likely true is that the median is in the 6-10 interval and the mean is in the 6-10

There were a total of 30 different pieces of data collected, so the 15th and 16th pieces of data that would create the median. Both the 15th and 16th numbers would be in the 6 - 10.

If you find the average of the middle data point in each interval the mean would be approximately 7.2. This is in the 2nd interval (6-10).

Find the area of the figure.
Vesnalui [34]

Answer:

AREA = 4,850

Step-by-step explanation:

split into two pieces  

formula for triangles- base x height divided by 2

20 x 50 = 100 / 2 = 50

(130 - 50 = 80)

80 x 120 = 9,600 / 2 = 4,800

add...

4,800 + 50 = 4,850

Diego's sister is twice his age minus 9 years. She is also as old as half the sum of the ages of Diego and both of his 12-year-o
slava [35]

Answer:

Diego is 14 years old.

Sister is 19

Step-by-step explanation:

x = Diego's age

<u>x</u><u> </u><u>+</u><u> </u><u>2</u><u>4</u>

2x-9 = 2

First to get rid of the fraction we multiply each side by 2

2(2x-9) = 2((x+24)/2)

4x-18 = x+24

The we isolate x

4x-18 = x+24

<u>-x+18 -x+18</u>

<u>3x</u> = <u>42</u> Now we divide each side 3

3 3

x = 14

So Diego is 14

Now we can solve for his sister. We can use one of the two equations from earlier to do this.

Plug 14 in for x and then solve for his sister

2(14)-9

28-9

19

His sister is 19
