0.07
45h represents how much it costs per hour to get it fixed and how long it takes to get it fixed
0.07(45h) would represent the tax because it is 7% of the cost pretax
Answer:
32 Meters
Step-by-step explanation:
A square has 4 equal sides so all you have to do is divide 128 by 4
Answer:
i)
Variables: length of bolt, number of flaws of bolt
ii)
Length of bolt: Quantitative continuous
number of flaws of bolt: Quantitative discrete
iii)
Observational unit: Bolts
iv)
sample size=75
Step-by-step explanation:
i)
The variables in the conducted study are "length of bolt" and "number of flaws on each bolt" because quality engineer is interested in evaluating the length of bolt and the number of flaws each bolt is having. Thus, the length and number of flaws for each bolt varies and we can say that "length of bolt" and "number of flaws on each bolt" are two variables in the conducted study.
ii)
The length of bolt can be presented numerically and further that the length of a bolt is measurable and thus, the length of bolt is a quantitative continuous variable.
The number of flaws of each bolt can be presented numerically and further that the number of flaws of each bolt can be counted and thus, the number of flaws of each bolt is a quantitative discrete variable.
iii)
The conducted study indicates that observational units are "bolts" because for each bolt its length and flaws are determined.
iv)
The sample size is 75 because a quality engineer selected 75 bolts and then measured its length and flaws.
Answer: d. 3
Step-by-step explanation: 12 inches in a foot
Answer:
Nadia is correct
Step-by-step explanation:
Rate of change = y/x
Using a point on the graph, say, (3, 8),
Rate of change = 8/3.
Therefore, Nadia's answer is correct while that of Nolan is wrong.
