How many 3/4 cup servings are in 12 cups of cherries?
1 answer:
Answer:
16 serving.
Step-by-step explanation:
Given: 3/4 cup servings.
Now, computing the number of serving in 12 cups of cherries.
Using unitary method to solve.
∴ Number of serving=
Number of serving in one cup is
Number of serving in 12 cups =
Number of serving in 12 cups=
∴ There are 16 serving is possible in 12 cups of cherries.

This is the same as showing the following system of equations doesn't have a solution:
or in matrix form,
The quickest way to check if there is a solution is to check whether the coefficient matrix is invertible. If its determinant is 0, then it is not invertible.
And the quickest way to show that the determinant is 0 is by observing that the third row is a linear combination of the first two rows:
(-2, 9, 6) - (-3, 2, 1) = (-2 + 3, 9 - 2, 6 - 1) = (1, 7, 5)
So there are indeed no such scalars <em>c₁</em>, <em>c₂</em>, and <em>c₃</em>.
Answer:
But we need to calculate the mean with the following formula:
And replacing we got:
And for the sample variance we have:
And thi is the best estimator for the population variance since is an unbiased estimator od the population variance
Step-by-step explanation:
For this case we have the following data:
1.04,1.00,1.13,1.08,1.11
And in order to estimate the population variance we can use the sample variance formula:
But we need to calculate the mean with the following formula:
And replacing we got:
And for the sample variance we have:
And thi is the best estimator for the population variance since is an unbiased estimator od the population variance
