In the accompanying diagram of rectangle ABCD, diagonal AC is drawn, DE = 8, DE 1 AC, and m2 DAC = 55. Find the area of rectangl

Aneli [31]

Answer:

sin (55) = DE / AD

AD = DE / sin (55)

AD = 8 / sin (55)

And

tan (55) = DC / AD

tan (55) = DC / [8 / sin (55) ]

DC = 8 tan (55) / sin (55)

AD * DC =

[8 /sin (55) ] [ 8 tan (55) / sin (55) ] = 136 units^2

The spinner for a board game has eight colors the arrow can land on. What are the degrees of freedom for a goodness-of-fit test

Juliette [100K]

Answer: Option 'c' is correct.

Step-by-step explanation:

Since we have given that

Number of colors that the arrow can land on = 8

We need to find the degrees of freedom for a goodness of fit test of the fairness of this spinner.

As we know that degree of freedom is 1 less than the size of sample.

So, Mathematically, it is expressed as below:

So, Degree of freedom would be

$v=n-1\\\\v=8-1\\\\v=7$

Hence, Option 'c' is correct.
