The degree of freedom is 6.
The degrees of freedom for the chi-square are calculated using the following formula: df = (r-1)(c-1) where r is the number of rows and c is the number of columns.
Given:
rows= 3
column= 4
So, degree of freedom
= (row-1)(column-1)
=(3-1)(4-1)
=2*3
=6
Hence, the degree of freedom is 6.

Answer:
75 units²
Step-by-step explanation:
PL² = 6² + 8²
PL² = 100
PL = 10
Triangles PAL and MPL are similar triangles
6/8 = PM/10
PM = 10 × 6/8 = 7.5
Area = 7.5 × 10
24/25
flip the sign to multiplication and change 5/8 to 8/5 and multiply straight across.
3/5 x 8/5 = 24/25
