Answer:

$\bar X = \frac{52384 +54079 +52762 +54364 +52584+53987 +53108 +51588 +50554 +53987}{10}=52939.7$

$Mode= 53987$

$Median = \frac{52762+53108}{2}=52935$

$Midrange=\frac{50554+54364}{2}=52459$

Step-by-step explanation:

We can calculate the mean with the following formula:

$\bar X = \frac{\sum_{i=1}^n X_i}{n}$

And if we replace the values given we got:

$\bar X = \frac{52384 +54079 +52762 +54364 +52584+53987 +53108 +51588 +50554 +53987}{10}=52939.7$

The mode is the most repeated value and for this case with a frequency of 2 the mode is:

$Mode= 53987$

In order to find the median we need to order the dataset on increasing way like this:

50554, 51588, 52384 ,52584, 52762

53108, 53987 , 53987 , 54079, 54364

Since we have 10 values an even number the median is calculated from the average between positions 5 and 6 on the data ordered, and we got:

$Median = \frac{52762+53108}{2}=52935$

The mid range is defined like this:

$Midrange = \frac{Max +Min}{2}$

And if we replace we got:

$Midrange=\frac{50554+54364}{2}=52459$

A. State the coordinates of each point and in which quadrant they lie.

olga_2 [115]

Answer:

I (1, 2) quadrant 1
J (3, -1) quadrant 4
K (-4, 0) x-axis
L (-4, 2) quadrant 2
M (4, -4) quadrant 4

b) (-4, 0)

c) (4, 2)

d) (-3, 1)

Step-by-step explanation:

I (1, 2) quadrant 1
J (3, -1) quadrant 4
K (-4, 0) x-axis
L (-4, 2) quadrant 2
M (4, -4) quadrant 4

b) (-4, 0) doesn't move as it is already on the x-axis

c) (4, 2)

d) (-3, 1)

reflected in the x-axis = (3, 1), then reflected in the y-axis = (-3, 1)

How can you calculate the circumference if you know the circle’s radius? Write a formula please.

Alika [10]

C=2πR
C equals the <span>circumference of the circle, while π is 3.14 and R is the radius. them multiply that by 2
