So if we know the volume of a cube is given by V = x ^ 3, and V = 3 3/8, then 3 3/8 = x ^ 3

So here we now know we have to find the, err, triple square root or something of 3.

Since square root is just x ^ 1/2, then we know that it would be x ^ 1/3 to figure out this problem.

So just replace x with 3 3/8, to get 1.5.

So the answer you're looking for is 1.5.

In order for you to use the goodnees-of-fit test, the test of independence, or the test of homogeneity, the expected frequencies

nataly862011 [7]

The condition for the expected value in the goodness of fit test is that the expected frequency is at least 5.

According to the statement

we have to find the condition of the expected values in the case of testing of goodness-of-fit test.

So, For this purpose we know that the

The goodness of fit test is of a statistical model describes how well it fits a set of observations. Measures of goodness of fit typically summarize the discrepancy between observed values and the values expected.

So, The main condition of the expected value for the goodness of fit test is

For each category, the expected frequency is at least 5.

Without this condition the test is not possible, so overall this the main condition related the goodness of fit test.

So, The condition for the expected value in the goodness of fit test is that the expected frequency is at least 5.

Answer:

₹14000

Step-by-step explanation:

Let c represent the cost price, and m represent the marked price.

c × (1 +40%) = m

m × (1 -15%) - c = ₹1900

Using the first expression for m, the second equation becomes ...

1.40c×0.85 -c = ₹1900

0.19c = ₹1900

c = ₹1900/0.19 = ₹10000

Then the marked price was ...

m = 1.40c = 1.40×₹10000 = ₹14000

The marked price was ₹14000.

_____

The selling price was ₹11900.
