Doug is analyzing the daily profits from the past month for three of his restaurant franchises. He has calculated the mean and s

tandard deviation of the data, in dollars, as shown below.
Location A Location B Location C
Mean = 6,127.85
SD = 413.51 Mean = 6,296.07
SD = 440.67 Mean = 6,191.28
SD = 330.83

For which store does 68% of the data lie between $5,714.34 and $6,541.36 (1 SD from the mean)?


2.
For which location does 95% of the data lie between $5,529.62 and $6,852.94 (2 SD from the mean)?


3.
Which location had the highest average daily profit during the past month?

Answer:

For product A, the product is increasing, for the bigger the number you plug into x (due to the fact that the numbers become bigger because of the time: year 1, year 2, etc)

Product A is 82% change rate, while

product B is 983.45/4 = 245.8625,  1756.16/3 = 585.3867

Product B is 245.8625/585.3867

product B is 42% change rate

Product A change rate is higher than Product B by 40%

Step-by-step explanation:

Hope this helped! :)

Part A: Explain why the x-coordinates of the points where the graphs of the equations y = 4-x and y = 2x + 3 intersect are the s
ale4655 [162]
Part A: Explain why the x-coordinates of the points where the graphs of the equations y = 4-x and y = 2x + 3 intersect are the solutions of the equation 4-x = 2x + 3.

Because the point where the graphs intersect is a point that meets both rules (functions) y = 4 - x and y = 2x + 3 meaning that y from y = 4 - x equals y from 2x + 3 and also both x have the same value.

Part B: Make tables to find the solution to 4-x = 2x + 3. Take the integer values of x between -3 and 3.

x values    4 -x         2x + 3

-3              4-(-3)=7     2(-3)+3 =-3
-2              4-(-2)=6     2(-2)+3 =-1
-1              4-(-1)=5     2(-1)+3 = 1
0                4-0=4        2(0)+3 = 3
1                4-1=3         2(1)+3=5
2                4-2=2        2(2)+3 = 7
3                4-3=1        2(3)+3 = 9

The the solution is between x = 0 and x =1

Part C: How can you solve the equation 4-x = 2x + 3 graphically?

Draw in a same graph both functions  y= 4 - x and y = 2x +3.

Then read the x-coordinates of the intersection point. That is the solution.

Solve 3/4x+1/4y=5 for y
Hitman42 [59]

Answer:

y=-3x+20

Step-by-step explanation:

3/4x+1/4y=5

-3/4x           -3/4x

1/4y=5-3/4x

divide the whole entire equation by 1/4 like this: (4)1/4y=4(5-3/4x)

Your answer is y=-3x+20
