4 0

Answer:

It's is A  and   D.

Step-by-step explanation:

Tan^2 theta cos 2theta

= (sin^2 theta / cos^2 theta )( 2 cos^2 theta - 1)

= 2 sin^2 theta  - sin^2 theta / cos^2 theta

= 2 sin^2 theta - tan^2 theta.

Tan^2 theta  cos 2theta

= ( 1 / cot^2 theta) * cos 2theta

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.

tresset_1 [31]

Answer:

7/4 * pi

Step-by-step explanation:

Area of circle = pi * r^2

Find radius:

pi * 49/64 = pi * r^2

49/64 = r^2

7/8= r

Circumference of circle = 2pi * r

2 * pi * (7/8) = 7/4 * pi

Assuming that the answer is in terms of pi as the question is in terms of pi
