1/4
Because......
Dice=6
From 1-6, only 2,4,6 are even numbers( or multiple of 2 )
So 3 ( numbers of even numbers ) /6
There are two dices we need to roll..
So 3/6 X 3/6
We simplify 3/6 by 2 :
1/2 X 1/2
Which equals 1/4
<span>The data of set X has a greater spread than that of set Y. This only means that the Standard Deviation of data set X is greater than the standard deviation of data set Y. The standard deviation is larger when data is more spread out.</span>
Answer:
e. none of these
Step-by-step explanation:
Primary interest in designing randomised block experiment is to : reduce the within treatment variation, to more easily detect differences between means.
A randomised block design involves the experimenter dividing subjects into subgroups known as blocks. The blocks are designed as to reduce the variability within the blocks, compared to variability between the blocks. This intra blocks less variation & inter blocks more variation, make blocks mean well represent their differences.

Step-by-step explanation:
Answer:
6 in
Step-by-step explanation:
Let x = the side length of the original square.
They removed 3 in from each side of the original square, so the side lengths of the remaining square are x - 3 in.
The area of the smaller square is (x - 3)².
The area of the original square is x²
I assume the area of the smaller square is ¼ that of the original square. Then
1. Solve for x
2. Calculate the side length of the smaller square
(a) x = 2
Side length = x - 3 = 2 - 3 = -1 in.
IMPOSSIBLE. You can't have a negative side length.
(b) x = 6
Side length of smaller square = 6 - 3 = 3 in.
Side length of original square = x = 6 in
Check:
OK.
