Their are two solutions.
X = -2/7 = 0.286
X = 1
A sample of size <em>n</em> taken from a normally distributed population with mean <em>µ</em> and standard deviation <em>σ</em> has a sample mean of <em>µ</em> and standard deviation of <em>σ</em>/√<em>n</em>.
So the sample mean would still be 180.1, while the sample standard deviation would be 100/√94 ≈ 10.31.
Answer:
Step-by-step explanation:
9. (2, -2) (1,0) (3,0) shade in and connect the points making it look like a 'U'
10. (-3, 1) (-4, -1) (-2,-1) not shaded and connect points making it look like ^
11. (2,-2) (1,-3) (3,-3) (0,-6) (4,-6) not shaded and connect points making it look like ^
12. (3, -1) (2,-2) (4,-2) (1,-5) (5,-5) not shaded and connect points making it look like ^
sorry for not showing the work, giving the points was the easiest way to give you the answers(:
7) x^2y^2 over 16
8) 8m^9n^3 over 27
9) 4x^3y^2
10) -4x^10y^8
