Answer: 28.
Step-by-step explanation:
The median of a data set is defined as the middle value of a data set.
For instance, the median of the data set [4, 7, 8] would be 7 because it is the "middle value".
You can find this by sorting the numbers by smallest to largest:
2, 9, 15, 16, 21, 24, 28, 32, 34, 35, 37, 39, 40
There are 13 numbers in the set, so you can exclude the first 6 and last 6 numbers from the set to get your median, 28.
You find the scale factor which is 10/4=2.5
then times that by 6.
2.5×6=15 and take 6 from 15.
15-6=9
x=9
hope it helps :-)
Answer:
10 square in.
Step-by-step explanation:
The rectangles are similar by a scale factor of 3. We can tell because the quotient of two of the corresponding sides, 18 and 6, is 3 (18/6=3)
That means the width of ABCD is 3 times the width of WXYZ.
Let's say the width of ABCD is x. Then 18*x=90 because that's the area.
x=90/18=5
Now we have the width of ABCD, 5, so to get the width of WXYZ, we divide by 3, which is 5/3.
Now to get the area of WXYZ, we can do 5/3, the width, times 6, the length, which is 30/3=10.

Answer:
The graph in the attached figure
Step-by-step explanation:
we have
isolate the variable y
Adds 10 both sides
Divide by 2 both sides
The solution of the inequality is the shaded area below the dashed line
The slope of the dashed line is positive
The y-intercept of the dashed line is (0,5) (value of y when the value of x is equal to zero)
The x-intercept of the dashed line is (-3.33,0) (value of x when the value of y is equal to zero)
