Answer:
"The interquartile range (IQR) is a measure of variability, based on dividing a data set into quartiles. ... The values that divide each part are called the first, second, and third quartiles; and they are denoted by Q1, Q2, and Q3, respectively."
Step-by-step explanation:
90 seconds
73 seconds
67 seconds
Answer:
82 seconds
Step-by-step explanation:
(1.2*82)+125=223.4
(2.6*82)+10=223.2
These are the closest. If you are estimating this is the right answer
Answer:
7) 40
8) 23
9) 63
Step-by-step explanation:
180 degrees in a triangle. Add the 2 degrees they give you, and then subtract that from 180 to find the missing angle.
82 + 58 = 140 180 - 140 = 40
115 + 42 = 157 180 - 157 = 23
27 + 90 = 117 180 - 117 = 63
Hope this helps.
Answer:
7=40, 8=23, and 9=63
Step-by-step explanation:
The key info to solve is that in a triangle there are 180 degrees
7) we add 82 and 58 and then subtract the total from 180 to find x
=82 + 58 = 140, and 180 - 140 = 40, so 40=x
We do the same for the rest
115 + 42 = 157, and 180 - 157 = 23, so 23=x
Wait whats that square in the triangle? It represents 90 degrees, a right angle!
so, 27 + 90(right angle) = 117, and 180 - 117 = 63, so 63=x
