Is there translation in english
The reason the 2nd number is plus two because you start with a odd number like 3 so to get the next odd number you have to add 2 get it.
X+X+2=188
2x+2=188
Subtract 2
2x= 186
Divide by 2
X= 93
Numbers are 93,95
Check 93+95=188
Answer:
d. 2250.
Step-by-step explanation:
The calculation of mean square due to error (MSE) is shown below:-
Since there are four treatments i.e H0: μ1 = μ2 = μ3 = μ4
And, the SSTR is 6,750
Based on this, the mean square due to error is
= 

= 
= 2,250
Hence, the mean square due to error is 2,250
Therefore the correct option is d.
All the other information is not relevant. Hence ignored it
Y = 15
x - y = 30
We replace y with the given value:
x - 15 = 30
x = 30 + 15
x = 45
