Answer:
(x + 3)² + (y - 1)² = 80
Step-by-step explanation:
Circle equation: (x - h)² + (y - k)² = r²
We are given <em>h</em> and <em>k</em>, so we just plug that in:
(x + 3)² + (y - 1)² = r²
To find <em>r</em>, we need to use distance formula: 
between the center of the circle and the point on the circle. We should get √80 as <em>r</em>. We plug that in to get our answer:
(x + 3)² + (y - 1)² = 80
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:
20%
Step-by-step explanation:
To find this, set up a ratio of percent over 100 equals is over of. Is being 32 and of being 160.
= 
Then, cross multiply. Multiply 32 by 100 before dividing by 160 in order to get the final answer of 20%.
32 x 100 = 3200
3200/160 = 20
Hope this helps!
We have two ways to solve this question
1)sin45=4√2 /x
√2 /2 =4√2 /x
X=8
2)Pythagorean theorem
In a 45-45-90 degree triangle
(4√2)^2+(4√2)^2=x^2
X=8
