velikii [3]

Answer:

Step-by-step explanation:

Given the data:

180kg, 250kg, 200kg, 209kg, 195kg, 205kg, 190kg, 188kg, 192kg

The interquartile range (IQR) = Q3 - Q1

Reordering the data:

180, 188, 190, 192, 195, 200, 205, 209, 250

Q3 = 3/4(n+1)th term

Q3 = 3/4(10) = 7.5 th term = (205+209)/2 = 207

Q1 = 1/4(n+1)th term

Q1 = 1/4(10) = 2.5th term = (188+190)/2 = 189

Q3 - Q1 = 207 - 189 = 18

What is the mid point in the photo?

Irina18 [472]

Step-by-step explanation:

$midpoint = ( \frac{ \frac{1}{3} - \frac{7}{3} }{2} , \frac{ \frac{5}{12} + \frac{7}{12} }{2} )$

$= ( \frac{ \frac{ - 6}{3} }{2} , \frac{ \frac{12}{12} }{2} )$

$= ( \frac{ - 2}{2} , \frac{1}{2} )$

$= ( - 1,0.5)$
