Step-by-step explanation:
Baseball Basketball Football Total
Group 1 27 28 45 100
Group 2 26 28 46 100
Group 3 30 26 44 100
Now we have from the table that the number of people who prefer to watch football is close to 45.
Hence, out of 1225 people a reasonable estimate of the number of people who prefer to watch football is calculated as:
Hence, to the nearest whole number it is: 551

Step-by-step explanation:
we have
----> inequality A
The solution of the inequality A is the shaded area below the solid line
The y-intercept of the solid line is -4
The x-intercept of the solid line is -1
The slope of the solid line is negative
----> inequality B
The solution of the inequality B is the shaded area above the solid line
The y-intercept of the solid line is 2
The x-intercept of the solid line is -2
The slope of the solid line is positive
The solution of the system of inequalities is the shaded area between the two solids line
