Prompt: Data plays a crucial role in decision-making because it can reveal relationships between different quantities. We can of

ten use linear equations to model these relationships and make predictions about the data. Think about a situation when you needed to analyze data. What types of trends did you find in the data? How did noticing the trends help you make a decision related to the situation?
In industry, data analysis is essential to recognize the challenges a company faces, and to analyze data in practical ways. Information is purely statistics and estimates in and of itself. Analysis of data organizes, interprets, integrates, and translates the data into usable knowledge that incorporates the data meaning. A situation in which I had to analyze data was while I was collecting data for a school project on how sleeping with a phone in the bedroom vs. sleeping without a phone in a bedroom. When I graphed this data as a bar graph, I found that it showed that more people reported better sleeping patterns when they did not have a phone in the bedroom, and the opposite for when they did. A graph makes a connection between quantities more visible in ways that a table and formula do not. This would help the person viewing the graph to come up with an answer far more easily, as the graph allows them to view the data in a way that is simpler to grasp and translate.

Answer:

You can use a chart to analyze the number of Push-Ups you do for five weeks. I found an uptrend. It helped me make a decision related ton the situation by seeing what the relationship in the graph or situation is, also it helps if you know what type of graph your looking at. Also it helped  determine the slope of the graph.

Answers:

  • Person A receives at least 800 dollars, but no more than 1600 dollars
  • Person B receives at least 1000 dollars, but no more than 2000 dollars

=============================================================

Explanation:

We don't have enough information to nail down exact figures, but we can make a range estimate.

The two people (call them A and B) share the profits in the ratio of 4 to 5

In shorthand notation, we can say the ratio is 4:5

This means person A gets 4x dollars while person B gets 5x dollars

The ratio 4x : 5x reduces to 4:5 after dividing both parts by x. The variable x is some positive real number.

The total profit is therefore 4x+5x = 9x dollars

This expression 9x is between 1800 and 3600 dollars, including both endpoints

We then can say...

1800 \le 9x \le 3600\\\\\frac{1800}{9} \le \frac{9x}{9} \le \frac{3600}{9}\\\\200 \le x \le 400

We see that x = 200 is the smallest possible x value. This leads to person A and B receiving 4x = 4*200 = 800 dollars and 5x = 5*200 = 1000 dollars respectively. Note how the ratio 800:1000 reduces to 4:5 after we divide both parts by 200. We can see that 800+1000 = 1800 which is the lowest profit possible.

The inequality above shows that x = 400 is the largest x value possible. If this is the case, then person A receives 4x = 4*400 = 1600 dollars while person B receives 5x = 5*400 = 2000 dollars. The ratio 1600:2000 reduces to 4:5 after we divide both parts by 400. We can see that 1600+2000 = 3600 is the largest profit possible.

-------------------------

To summarize:

  • Person A can receive anywhere between 800 dollars and 1600 dollars (inclusive of both endpoints).
  • Person B can receive anywhere between 1000 dollars and 2000 dollars (inclusive of both endpoints).

The actual amount they receive will depend on what the actual profit is. Since we're only given the range of the profit, we can only make an estimated guess of the range for each partner.

-------------------------

Side note: For either person, the ratio of the max to min is 2:1. This tells us that the max amount they receive is double compared to the min amount they receive. It's no coincidence that 3600 is double that of 1800.

Find the lateral area of the cone in terms of π.
Andreyy89

Answer:

15\pi\ cm^{2}

Step-by-step explanation:

we know that

The lateral area of the cone is equal to

LA=\pi rl

where

r is the radius of the base

l is the slant height

we have

r=3\ cm

Applying the Pythagoras Theorem find the slant height

l^{2}=3^{2} +4^{2}\\ \\l^{2}=25\\ \\l=5\ cm

substitute in the formula

LA=\pi (3)(5)=15\pi\ cm^{2}

For the equation, complete the solution. 8x + y = −7 <br> (x, y) = , 1
butalik [34]

Answer:

(x, y) = (-1, 1)

Step-by-step explanation:

8x + y = −7

for y = 1

8x + 1 = -7

subtract 1 from boh sides

8x = -8

divide bot sides by 8

x = -1

(x, y) = (-1, 1)
