Answer:
6√3
Step-by-step explanation:
√108= √(36×3)
√36×√6= 6×√3
=6√3
First find slope intercept for our equation
-6x+3y=18.9
3y=6x+18.9
y=2x+6.3
Since b is y intercept, y intercept is (0,6.3)
Now in x intercept y is equal to 0.
So substitute it for our equation.
0=2x+6.3
-2x=6.3
x=-3.15
So x intercept is (-3.15, 0)
Answer: The probability of an odd number is 1/2, and the probability of a tail is also 1/2, so the probability of both occurring is the product, 1/4.
Step-by-step explanation: The coin is fair, the probabilities of getting a head and a tail are equal to 12 . The probability of getting an even number on a die is 36=12 because among 6 results there are 3 even numbers
Answer:
Step-by-step explanation:
For this case we have a sample of n =10 and we have the following statistics:
And we want to estimate the population variance. We need to remember that the population variance is given by this formula:
And the sample variance is given by:
And we can find a formula for the population variance in terms of the sample deviation like this:
And replacing we got:
