Answer:The Mann-Whitney U test is used to compare differences between two independent groups when the dependent variable is either ordinal or continuous, but not normally distributed. ... The Mann-Whitney U test is often considered the nonparametric alternative to the independent t-test although this is not always the case.
Step-by-step explanation:that would de why
Not sure why, but I wasn't able to post my solution as text, so I've written it elsewhere and am posting screenshots of it here.
In the fifth attachment, the first solution is shown above the second one.
Answer:
The answer to your question is: D = non of the above
Step-by-step explanation:
Data
-4x - 4y = -5 (I)
x - 2y = 1 (II)
Process
Find the slopes of both lines
(I) -4x - 4y = -5
-4y = 4x + 5
y = 4/-4 x + 5/-4
y = - x + 5/4
(II) x - 2y = 1
- 2y = - x + 1
y = -1/-2 x + 1/-2
y = 1/2 x - 1/2
The slopes are different slope 1 = -1 and slope 2 = 1/2, so there is no relation between the lines.
Answer:
265.1 units²
Step-by-step explanation:
Area of circle:
3.14 × 12²
452.16
Side of the triangle:
s² = 12² + 12² - 2(12)(12)cos(120)
s² = 432
s = 12sqrt(3)
Area of triangle:
½ × s × s × sin(60)
½ × 432 × sqrt(3)/2
187.0614872
Shaded area:
452.16 - 187.0614872
265.0985128 units²
