Answer:

x = 85°

Step-by-step explanation:

Because the sum of the angles in a triangle is 180°, we can find ∠CDB.

180° - ∠CBD - ∠BCD = ∠CDB.

180° - 35° - 50° =

180° - 85° =

95°

So, ∠CDB is 95°

Then, because a line has 180°, we can find ∠CDA.

180° - ∠CDB = ∠CDA.

180° - 95° = 85°

So, x = 85°

Answer:

The correct option is 3.

Step-by-step explanation:

It is given that the quantities of blue and green paints used for each mix and connected them using a line segment, as shown in the graph below:

The line have two end points A(1,2) and B(9,14).

Domain is the set of inputs. In a graph all the values of x for which the graph is defined, are domain of the function.

The line is defined from x=1 to x=9. So, the domain of the function lies between 1 to 9 (inclusive).

$1\leq x\leq 9$

Therefore, option 3 is correct.

A two-factor between-subjects design is evaluated. The F-value for Factor A has df = 1, 40 and the F-value for Factor B has df =

finlep [7]

Answer:

The df values for the A x B interaction are also 3,40

Step-by-step explanation:

The F-value for Factor A has df = 1, 40

The F-value for Factor B has df = 3, 40.

The df values for the A x B interaction are also 3,40

This is because the source of variation between columns has ( c- 1); rc(n-1) degrees of freedom and the source of variation between rows has (r-1); rc(n-1) degrees of freedom and the source of variation of interaction

(between rows and columns) has ( c-1) ( r-1); rc(n-1) degrees of freedom.

Therefore

Factor A: ( c- 1); rc(n-1) = 1,40

<u>Factor B: (r-1); rc(n-1) = 3,40</u>

Interaction : ( c-1) ( r-1); rc(n-1) = 3*1,(40)= 3,40

where c refers to columns , r refers to rows and n refers to the total sample size.
