Answer: B
Step-by-step explanation:
In statistical terms ,ordinal scale contains things that you can place in order.
For example, hottest to coldest, lightest to heaviest, richest to poorest. Basically, if you can rank data by 1st, 2nd, 3rd place (and so on), then you have data that’s on an ordinal scale.
To find the IQR you first need to write it in numerical order
77, 81, 83, 84, 86, 86, 88, 92
IQR is just Q3 - Q1
Q1 is the middle of the first have, since it has an even set of 4 numbers in the first half you need to take the average of the two middle ones.. which is 82
Q3 done the same process would be 87.
87 - 82 = 5
IQR = 5
Answer:
D
Step-by-step explanation:
you can just find the value of y and try some number of x
i.e. if x = 0, both of them will be 0
x = 1
G(x) result is -2
F(x) result is 1
x= -1
G(x) result will be 2
F(x) result is -1
so from these we can prove that G(x) is bigger graph than F(x) but flip vertically by y axis
Y = 5x + 4
Gradient = slope = 5
(0,4) = y - intercept
