When studying populations, it is very difficult to evaluate all individuals, whether by size, difficulty, budget, etc., to solve this, the statistical inference deals with all the mathematical procedures that allow drawing conclusions for the population, with a degree of calculable error, from a sample of it.
Answer
C. Is the process of drawing inferences about the population based on the information taken from the sample
1. cost +1.25*cost = 500
2.25*cost = 500
cost = 500/2.25 = 222.22
Clyde should pay $222.22 or less for the pottery.
2. cost +0.25*cost = $12.50
1.25*cost = $12.50
cost = $12.50/1.25 = $10.00
The cost to Orchard Supply of a bag of fertilizer is $10.00.
Answer:
Angle 1 is 60°
Step-by-step explanation:
(36+90)+C=180
126+C=180
C=180-126
=54
Answer=54
Answer:
Highest score is 21.5
Step-by-step explanation:
Let the highest score be h
Let the lowest score be l
Therefore
h = 3l - 4 (1)
and
h - l = 30 (2)
I. E.
h = 30 - l (3)
Substituting (3) in (1)
30 - l = 3l - 4
Collecting like terms
30 + 4 = 3l + l
34 = 4l
l = 34/4
l = 8.5
Then substitute l = 8.5 in (1)
h = 3l - 4
h = 3(8.5) - 4
h = 25.5 - 4
h = 21.5
