Suppose that the numbers that the boy being cast from the dice are 3 4 5 6.
3 stands for white, 4 stands for red, 5 stands for green and 6 stands for blue.
We need to interpret the statement given above. The set of numbers is 3 4 4 6 6 5.
First, we need to get the mean of this set. Add all the numbers and divide by the total number that the set has.
3+4+4+6+6+5= 28 / 6
= 4.67 The mean is 4.67
For the variance, we will use the mean above ( 4.67 )
1. Squared the mean and subtract how many numbers are present in the set.
4.67x4.67= 21.8089 /6 = 3.64 set aside this result
2. Next squared all the numbers present in the set and add the result
3x3= 9 , 4x4= 16, 4x4=16, 6x6=36, 6x6=36, 5x5=25
9+16+16+36+36+25= 138
3. Subtract the result of #2 with #1
138 - 3.64= 134.36 set this aside
4. Subtract 1 from the total numbers you have in your set
6 - 1= 5
5. Divide the result we have in #3 with the result of #4
134.36 / 5= 26. 872
So the variance is 26.872
Answer:
(-2,-1)
Step-by-step explanation:
This is a special 60-30-90 triangle, and the angle measure of x is
Answer:
sqrt(2)/2
Step-by-step explanation:
Sin(135) = sin(180-135) = sin(45)
= 1/sqrt(2) or sqrt(2)/2
sqrt: square root
Answer:
see below
Step-by-step explanation:
First determine how much is subtracted from the account
12.57+24.95+36.86 =74.38
They charge .15 per check=3*.15 = .45
Subtract the amounts of the checks and the check fees
139.50-74.38-.45 =64.67
