Answer:
The correct option are: (A), (B), (C) and (E).
Step-by-step explanation:
The One-Way ANOVA is a statistical test used to compare the three or more population means.
The hypothesis is:
<em>H</em>₀: The population means are equal, i.e. μ₁ = μ₂ = μ₃ =...= μₙ
<em>H</em>ₐ: At least one of the population mean differ.
The Assumptions of One-way ANOVA are:
- The samples selected from each population are independent of each other.
- The population distribution of the dependent variables follow Normal distribution.
- The population variances are always equal for all the groups.
Thus, the correct option are: (A), (B), (C) and (E).
Answer:
Step-by-step explanation:
A
Answer:
Please check the attached figure!
Step-by-step explanation:
Part a)
Point A is located at the x-coordinate x=-4 and y-coordinate y=1.
Hence, the coordinates of point A = (-4, 1)
Part b)
Point B(3, -2) has been plotted and is shown in the attached figure.
It is clear from the attached diagram that point B is located at the x-coordinate x=3 and y-coordinate y=-2. Hence, the coordinates of point B = (3, -2)
Part C)
Point C has the same x-coordinate as point A i.e. x=-4 and the same y-coordinate as point B i.e. y=-2.
Hence, the coordinates of point C = (-4, -2). Point C is also plotted as shown in the diagram.
AB is the longest side, so ∠C is the largest angle.
use law of cosine: 16²=9²+12²-2*9*12cosC
216cosC=81+144-256=-31
cosC=-0.14352
C≈98
12 + n
if you substitute n for any whole number and simplify. you will find that 12+n does not equal any others. for example, i used 6 in place of n and all equations gives you 10 except 12+n
hope this helps!
