Answer:
Sam is 12, sam's brother is 19, and sam's mom is 32.
Step-by-step explanation:
First the equation you need to use is S+7+S+3S-4=63(the variable s represents Sam), you combine the like terms which then equals 5S+3=63, then you use inverse operations. Subtract 3 on both sides, 5S=60, then you divide on both sides which equals S equals 12. Then you just plug in the number, S is Sam which means Sam's 12. Then 12+7 which is 19, Sam's brother. Then 3 times 12 minus 4 is 32. And if you check to make sure, 12+19+32 does equal 63.
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:
Could be 12 or 16. Need more information
Step-by-step explanation:
I believe the answer is degree 2
If you divide 2.3 by 1.15 to find out how much greater it is, the answer is 2.
