Answer: (b) -7/2, 6.
Step-by-step Explanation: We put x = 0; then y = 6; y-intercept of the line is (0,6).
For the slope: 4y = 24 - 14x; then, y = (-7/2)x + 6; the slope is -7/2.
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

Step-by-step explanation:
2nd qestions explanation
put value of x=2 in equation as x-2=0 from equation
(2)^3-6(2)^2+a2+10=2
8-24+a2+10=0
2a=-18+24
2a=6
a=3
