Find for x if sin x cot x csc x = sqrt 2 ?

1 answer:

4 0

Since sin and csc are inverses it is the same as saying cot(x) = sqrt 2 which is tangent of x as sqrt2/2 there is no rational answer for x

Answer:

The correct option is (A).

Step-by-step explanation:

The p-value is well-defined as per the probability, [under the null-hypothesis (H₀)], of attaining a result equivalent to or more extreme than what was the truly observed value of the test statistic.

A small p-value (typically p < 0.05) specifies strong evidence against the null hypothesis (H₀), so the null hypothesis is rejected. A p-value less than 0.05 is considered as statistically significant.

A large p-value (p > 0.05) specifies fragile proof against the H₀, so the null hypothesis is failed to be rejected.

In this case the p-value of the test is,

p-value = 0.003

And the significance level of the test was,

α = 0.05.

p-value = 0.003 < α = 0.05.

The p-value less than the significance level of the test.

Thus, the results are statistically significant.

The correct option is (A).
