N+d=47
5n+10d=295
divide 2nd by 5
n+2d=59
we have
n+d=47
n+2d=59
eliminate n
multiply first equaton by -1 and add to other equaton
-n-d=-47
<u>n+2d=59 +</u>
0n+1d=12
d=12
sub back
n+d=47
n+12=47
minus 12 both sides
n=35

x = 1.75 rounded in seconds
Answer:
bro its so easy
Step-by-step explanation:
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
