Answer:
Step-by-step explanation:
Mean roughly means the average of all the results. Add all of them up and divide it by the number of items there are. Median, basically means, you line them up from low to high numerically and the middle number.
To graph ty function simply make a table of values, where you choose any value for x and substitute that value in the function.
Then take the absolute value of the expression in the square bracket.
It is always positive, the absolute value of -6 is 6 etc.
Then graph the resulting points.
Another way to do it is simply draw the graph of y = |x| then move it 2 spaces to the right and 4 spaces down, I believe.
The graph is proportional
Answer:
41 degrees
Step-by-step explanation:
All three angles in a triangle must add up to 180 degrees. The picture already tells you that B is 63 degrees. This means A and C should both add up 117 degrees. If A is 2x+8 and B is x+7, then A+B is 3x+15. This means that 3x+15 is equal to 117 degrees.
- 3x + 15 = 117
- 3x = 117 - 15
- 3x = 102
- x = 102/3
- x = 34
Now that we know that x is 34, we plug it in. X + 7 becomes 34 + 7 degrees which is equal to 41 degrees.
The store must sell 60 of each set each to obtain the biggest possible income
<h3>How to determine the number of each gift set?</h3>
The given parameters can be represented using the following table:
<u>Set 1 Set 2 Available</u>
Notebook 2 3 300
Pen 1 1 120
Selling price 8 11.5
Using the above data values, we have:
Objective function: Max P = 8x + 11.5y
Subject to:
2x + 3y ≤ 300
x + y ≤ 120
Next, we plot the graph of the above inequalities (see attachment)
From the attached graph, we have:
(x,y) = (60,60)
Hence, the store must sell 60 of each set each to obtain the biggest possible income
