Answer:
C
Step-by-step explanation:
Anything that says congruent line segments using this figure is incorrect. There are no givens that indicate any congruency of segments. So both A and B are incorrect.
PRT and QTS are vertically opposite and are equal. All vertically opposite angles are equal to the angle across from them. C must be your answer.
PRT might Be equal to QTS. Most of the time this will not be true. D is not universally the answer.
Answer:
(1) 330
(2) 692
(3) 110
(4) 43.25
Step-by-step explanation:
The data provided is for the dying time of four different types of paint.
One-way ANOVA can be used to determine whether all the four paints have the same drying time.
Use Excel to perform the one-way ANOVA.
Go to Data → Data Analysis → Anova: Single Factor
A dialog box will open.
Select the data.
Select "Grouping" as Columns.
Press OK.
The output is attached below.
The required values are as follows:
(1)
Sum of Squares of Treatment (Between Subjects):
SST = 330
(2)
Sum of Squares of Error (Within Subjects):
SSE = 692
(3)
Mean Squares Treatment (Between Subjects):
MST = 110
(4)
Mean Squares Error (Within Subjects):
MSE = 43.25
General formula :
V = pi x radius squared x height
41.5 = pi x 4 x h
41.5 = 4pi x h
41.5/4pi = h
3.302465069 = h
