Answer: The median of the upper half of a set of data is the upper quartile ( UQ ) or Q3 . The upper and lower quartiles can be used to find another measure of variation call the interquartile range . The interquartile range or IQR is the range of the middle half of a set of data.
Step-by-step explanation:
Assume the girls sold X boxes in the first week. They sold in the second week X+5 and 2X+10 in the third week.
The sum X + X + 5 + 2X + 10 = 431
4X = 416. Therefore X = 104
The answers are:
a0 = 104
a1 = 109
a2 = 218
Hope that helps you :)
This dot plot shows a nonlinear association... this is because if you look at the plot you can tell that there isn’t a line going any direction, it’s kinda scattered..so there isn’t any outliers rather it’s a nonlinear plot
What are the numbers x and y are sopposed to be?
Answer: Angle C measures 132.5 degrees
Step-by-step explanation: What we have here is an irregular polygon with six sides. Two sides have been identified as 90 and 130. And the other sides are yet unknown. We shall start by computing the total sum of the interior angles of the six sided polygon.
The formulae for computing the interior angles of a polygon is given as (n - 2) x 180,
Where n stands for the number of sides of the polygon
Therefore in this diagram, sum of the interior angles equals
(6 - 2) x 180
= 4 x 180
= 720 degrees
That means the addition of all the given angles equals 720. This can be expressed as follows;
90 + 130 + (x + 10) + x + x + x = 720
220 + x + 10 + 3x = 720
By collecting like terms we now have
4x = 720 - 220 - 10
(Note that if a positive value crosses to the other side of an equation it becomes negative and vice versa)
4x = 490
Divide both sides of the equation by 4
x = 122.5
Therefore, since angle C is (x + 10)
C = 122.5 + 10
C = 132.5 degrees
