Plz help with these two question.The ages of 10 workers at a factory are shown. What is the mean absolute deviation for the group (round to the nearest tenth)?
A) 10.3
B) 12.7
C) 40.4
D) 127.8

The scatter plot shows a regression line of advertising dollars spent and sales. If the company were to spend $350,000 on advertising, what would be the predicted sales?
A) $116 million
B) $120 million
C) $118 million
D) $122 million

Answers

Answer 1

Answer: For number 1: you would add all the ages together, 23+19+50+49+67+34+30+59+40+33=404 and then divide that by how many workers(10) 404 divided by 10=40.4 and that is already rounded to the nearest tenth. So the answer to number 1 would be C. 40.4. Number 2: I'm just guessing but because the line on the graph shows is at around B) and C) is looks closer to $122 million, so I would go with D. $122 million

d. The slope of the line is undefined.

HOY -- horizontal line, 0 slope, represented by y = a number
VUX -- vertical line, undefined slope, represented by x = a number.

so we have y = 3
this is a horizontal line which has a 0 slope.

An adventure game has a number cube with 12 equal-size faces: some labeled with 1, some labeled with 2, and some labeled with 3. The game manufacturer tests the cube by rolling it 12, then 120, and then 1200 times.What is the best estimate of the number of faces labeled with 2?

Answers

The best possible estimate will be the amount of twos rolled out of twelve hundred times, divided by 100 and rounded to the nearest integer.

Or, you could just look at the die to find the exact number :)

Ranking the three from best to worst will be: point, line, plane. The justification is that, the starting concept determines the next one.

Step-by-step explanation:

The connection can be described by starting with the fundamental concept,procedure or strategy that give rise to the others. In this case, to form a line, you need to have points that join to extend infinitely in different directions. This means the point, is the fundamental concept, that will give the line.A plane is an infinite set of points that form a connected flat surface extending infinitely far in all direction. So here again, the plane exist where there is a set of points. However, a plane is named by three points that are in the plane but not in the same line. Hence, before naming a plane, the concept of a line should be considered. Ranking the three from best to worst will be: point, line, plane. The justification is that, the starting concept determines the next one.
