Answer:
The correct answer is D
Step-by-step explanation:
Answer:
C) Both sets have an interquartile range of 27.
Step-by-step explanation:
Sorted data
Set 1: 65, 66, 77, 79, 81, 93, 104, 105
Set 2: 1, 29, 56, 59, 60, 67, 72, 74
Median position: (8+1)/2 = 4.5th value
Ranges:
Set 1: 105 - 65 = 40
Set 2: 74 - 1 = 73
Medians:
Set 1: (79+81)/2 = 80
Set 2: (59+60)/2 = 59.5
IQR:
Set 1: (93+104)/2 - (66+77)/2
= 27
Set 2: (67+72)/2 - (29+56)/2
= 27
Answer:
{y|y≥−2}
Step-by-step explanation:
The domain is {x|x∈R}
The range is {y|y≥−2}
Answer:
Triangle
Step-by-step explanation:
The square root of 99 is irrational.
Answer:
Domain: all real numbers
The interval on which the function is increasing is : (0 , infinity)
The interval on which the function is decreasing is : (-infinity , 0)
The interval on which the function is constant is : ( 0,0 )
Step-by-step explanation:
f(r)=5r^2−4
This is a quadratic function.
vertex at (0, -4) and with positive coefficient for r^2
The interval on which the function is increasing is : (0 , infinity)
The interval on which the function is decreasing is : (-infinity , 0)
The interval on which the function is constant is : ( 0,0 )
