A Venn diagram can be represent set of relationship visually
Answer:
The answer to the question is
Point Estimate = 1.5
Margin of error = 0.3
Step-by-step explanation:
A point estimate as opposed to an interval estimate, presented in the question which consist of a range of values, is a specific point or single value to describe a given set of collected data. An example of a point estimate is the mean of a range of values hence the point estimate is given as
(1.2 + 1.8) ÷ 2 which is equal to 1.5
The margin of error is used to describe the required allowance in terms of statistical points or percentage points by which a given set of result could vary from the actual sample. It represents the expected error between the actual population and the survey result
In this case the margin of error from the mean is
1.5 - 1.2 = 0.3
Margin of error formula is z ×σ/√(n)
where z = z-score
σ = standard deviation
n = number of sampled data
Answer:
B The graph of g(x) is the graph of f(x) shifted to the right 6 unit
Answer:
(a) 75 minutes
(b) 50 minutes
(c) labeling speed = Number of books to label ÷ Time taken to finish labeling them
Step-by-step explanation:
Firstly, she has 750 books to label and she labels 10 books in a minute. Hence, the number of minutes it will take her will equal the number of books divided by the number of books labeled in a minute.
This will be 750/10 = 75 minutes
Secondly, we use the same approach here but the number of books she labeled in a minute is different. Hence we get 750/15 = 50 minutes.
Lastly, the relationship between her labeling speed and the number of minutes is shown as follows.
The speed has a unit of books/minute since it is a rate and this is equal to number of books labeled ÷ Time taken to label them
