Answer:
(1)
(2)
Step-by-step explanation:
Solving (1):
(a): Mean
This is calculated as:
So, we have:
Solving (b): The variance
This is calculated as:
Where:
and
So, we have:
So, we have:
Solving (c): The standard deviation.
This is calculated as:
Solving (2):
(a): Mean
This is calculated as:
So, we have:
Solving (b): The variance
This is calculated as:
Where:
and
So, we have:
So, we have:
Solving (c): The standard deviation.
This is calculated as:
1/2 (12)(5a+7b)
6(5a+7b)
30a + 42b -- I hope this helped
Is there a picture to go with this problem?
Answer:
6
Step-by-step explanation:
The computation of the least possible whole number is shown below:
Here we need the factors of 150 i.e.
= 3 × 5 × 2 × 5
Here we can add to one box and the 5 to the other box
And, now if we can add 3 to one box and in the other we can add 2 so they cant be equal to each other
Now lets try 5 × 6 and 5
So, here The perfect square is 900
= 30 × 30
= 900
Hence, the number would be 6
From the original positions, just flip the X value since it changes the X when flipping over the Y axis, so (3,2) (1,5) and (-2,1)
