We have a study involving 5 different groups that each contain 9 participants (45 total). What two degrees of freedom would we r
vivado [14]

Answer:

Degree of freedoms F(4,40)

Step-by-step explanation:

Given:

There is a study which is involving 5 different groups that each contains 9 participants (totally 45)

The objective is to calculate the degree of freedoms

Formula used:

Numerator degree of freedom = k-1

denominator degree of freedom=N-K

Solution:

Numerator degree of freedom = k-1

denominator degree of freedom=N-K

Where,

K= number of groups = 5

N= total number of observations

which is given as follows,

N=45

Then,

Numerator degree of freedom = k-1

=5-1

=4

Denominator degree of freedom = N-K

=45-5

=40

Therefore,

Degree of freedoms, F(4,40)

Please help I dont understand
Anastasy [175]

Answer:

Angle 2=160

Angle 3=10

Step-by-step explanation:

The rhombus is made up of two isoceles triangle.

Angle 1 measures 160.

Since the triangle is a isoceles triangle, the opposite angles of the congruent sides is equal angles to each other.

So the reamaing angles in the top triangle are equal so we can use this equation

Remeber that triangle maximum degree it can hold is 180

160 + x + x = 180

160 + 2x = 180

2x = 20

x = 10

We have two congruent triangle side they share Three sides. SSS

This means the corresponding angle of Angle 1 is Angle 2.

Angle 2=Angle 1 by CPCTC.

Angle 2=160

Angle 3 corresponds with one of the remaining congruent angles so it measures

10.

How do you divide 2\3 divided by 7\8 using kcf answer
xz_007 [3.2K]

Answer: \frac{16}{21}

<u>Step-by-Step Explanation:</u>

KCFmeans: Keep, Change, Flip

  • Keep: the first fraction
  • Change: the sign <em>from division to multiplication</em>
  • Flip: the second fraction

  \frac{2}{3} ÷ \frac{7}{8}

= \frac{2}{3} * \frac{8}{7}   <em>KCF is applied here!</em>

= \frac{2(8)}{3(7)}

= \frac{16}{21}
