Find the range of the following data.
2 answers:
Answer:
(D) 20
Step-by-step explanation:
We are given the data as the scores, these are:
83, 77, 88, 93, 97, 79, 94, 80, 97, 81
In order to find the range, firstly arrange the data in ascending order, we have
77, 79, 80, 81, 83, 88, 93, 94, 97, 97
Now, the range of the given data is equals to highest data point- lowest data point, thus
Therefore, the range of the given data set is 20.
Hence, option (D) is correct.

Answer:
The correct option is A.
Step-by-step explanation:
If a line passes through two points and
, then the equation of line is
Let y be the profit (in millions) after x years.
From the given graph it is clear that the line passes through the point (1,-100).
The company paid for these costs and made combined profits of $80 million after 4 years. It means the graph passes through the point (4,80).
The line passes through (1,-100) and (4,80). So, the equation of line is
Subtract 100 from both sides.
The function form is
Therefore, the correct option is A.
