Answer:
w = 12
Step-by-step explanation:
We are given the equation:

First, clear out the denominators by multiplying both sides by LCM. In this scenario, our LCM is 40. Thus, multiply both sides by 40:

Simplify the expressions/equations:

Isolate w-variable:

Hence, the solution is w = 12

Answer:
3
Step-by-step explanation:
A direct variation is of the form
y = kx
We know x and y so we can find k
81 = k *27
Divide each side by 27
81/27 = 27k/27
3=k
The constant of variation is 3
Answer:
3,315 is the answer
Step-by-step explanation:
1) Just divide
9945 ÷ 3 = 3,315
Not hard
But here my answer!
Answer:
i use the two sided t-test.
Step-by-step explanation:
it would be nearly impossible to ascertain with certain the proposition above but we would rather guess using the parameters that were available at the time.
generally in statistics, we use a two sided t-test when an area of a distribution is two-sided and tests whether a particular given sample in question is greater than or less than a exact range of values.
the two sided t-test is mostly used in null-hypothesis testing and testing for statistical significance.
