You randomly survey students about whether they like hamburgers or hot dogs. of 129 students who like hamburgers, 46 like hot do
Ludmilka [50]

 Here is the two-way table and the marginal frequencies in bracket:                          

                                 Like hamburger    do not like hamburger      Total

Like hot dog                    46(0.16)             54 (0.10)                        100(0.36)

Do not like hot dog          83(0.30)           95 (0.34)                        178(0.64)

Total                                 129 (0.46)             149 (0.54)                  278(1)

<h3>What is the two-way table?</h3>

Number of people who like hamburger but do not like hot dog = 129 - 46 = 83

Number of people who do not like hamburger and do not like hot dog = 149 - 54 = 95

Total number of people who like hot dog = 46 + 54 = 100

Total number of people who do not like hot dog = 83 + 95 = 178

Total = 100 + 178 = 278

The marginal frequency can be determined by dividing each number by the total number of people in the survey.

  • marginal frequency of people who like hot dog = 100 / 278 = 0.36
  • marginal frequency of people who do not like hot dog = 178 / 278  = 0.64

aev [14]
The sides of the square is 6 cm with a scale factor of 1.6
So the actual size will be
= 6 * 1.6
= 9.6 cm

Getting the area:
Area = s^2
Area = 9.6^2
Area = 92.16 square centimeters

Getting the perimeter:
Perimeter = 4*s
Perimeter = 4 * 9.6
Perimeter = 38.4 cm
