Answer:
The degrees of freedom associated with the critical value is 25.
Step-by-step explanation:
The number of values in the final calculation of a statistic that are free to vary is referred to as the degrees of freedom. That is, it is the number of independent ways by which a dynamic system can move, without disrupting any constraint imposed on it.
The degrees of freedom for the t-distribution is obtained by substituting the values of n1 and n2 in the degrees of freedom formula.
Degrees of freedom, df = n1+n2−2
= 15+12−2=27−2=25
Therefore, the degrees of freedom associated with the critical value is 25.

Answer:
Step-by-step explanation:
256
Every two triangles are similar. Therefore the sides of triangles are in proportion.
We have the equations:
1.
<em>cross multiply</em>
<em>divide both sides by 5</em>

<em>subtract 3 from both sides</em>

--------------------------------------
2.
<em>cross multiply</em>

<em>divide both sides by 3</em>

------------------------------------------
3.

<em>cross multiply</em>
<em>divide both sides by 5</em>

<em>subtract 12 from both sides</em>

----------------------------------------------
4.
<em>cross multiply</em>

<em>divide both sides by 3</em>
