Answer:
Table 1 = Proportional
y is 7 times x
Table 2 = Not proportional
Step-by-step explanation:
There are 100 cm in a meter so 16 cm is equal to 1600/48
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

Answer:
Step-by-step explanation:
1) 1 km = 1000 m
7.8 km = 7.8 * 1000
= 7800 m
2) 1 g = 1000 mg
1.6 g = 1.6 * 1000
= 1600 mg
