Answer:
2.) 7.8
Step-by-step explanation:
We can use Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
5^2 + 6^2 = c^2
25+36 = c^2
61 = c^2
Take the square root of each side
sqrt(61) = sqrt(c^2)
7.810249676 = c
Answer:
Step-by-step explanation:
Correct me is I'm wrong but I believe its a independent variable.
The mean is 35/5=7
The variance is the average of the sum of squared differences of each element from the mean:
v=((7-7)^2+(5-7)^2+(11-7)^2+(1-7)^2+(11-7)^2)/5
v=(0+4+16+36+16)/5
v=14.4
Area is equal to length times width, so 1.3x would represent the area. B is the answer.
