Response:
The average of the 10 sales figures for store A is $40,000.
Detailed explanation:
Provided;
yˆ= −3,000 + 1.2x...................... (1)
Where;
x = daily sales amounts at store A or the average of the 10 sales amounts for store A =?
yˆ = daily sales amounts at store B or the average of the 10 sales amounts for store B = $45,000
Substituting y = 45,000 into equation (1) and solving for x, yields:
45,000 = −3,000 + 1.2x
45,000 + 3,000 = 1.2x
48,000 = 1.2x
x = 48,000 / 1.2
x = 40,000
Consequently, the mean of the 10 sales figures for store A is $40,000.
The value of x is 12. This can be found using the Pythagorean theorem with c equal to 13 and b equal to 5, where a equals x.
A slope of 5/2 signifies that moving 2 units horizontally results in moving 5 units vertically. To visualize this, from any point on the line, shift 2 units right, and from there, move upwards until you intersect the line again. If the vertical movement is 5 units, the slope is confirmed to be 5/2. Option A indicates a slope of 5/2, B specifies a slope of 4/2, while C affirms the slope of 5/2. I can't clearly see the graphs represented in images D and E; however, E might have a slope of 5/2, which should be measured, and D clearly does not match the slope of 5/2, as it can be compared with A, demonstrating a significant difference, thus it can be eliminated.
