Answer: The numerator and denominator degrees of freedom (respectively) for the critical value of F are <u>4</u> and<u> 118 .</u>

Step-by-step explanation:

We know that , for critical value of F, degrees of freedom for numerator = k-1

and for denominator = n-k, where n= Total observations and k = number of independent variables.

Here, Numbers of independent variables(k) = 5

Total observations (n)= 123

So, Degrees of freedom for numerator  = 5-1=4

Degrees of freedom for denominator =123-5= 118

Hence, the numerator and denominator degrees of freedom (respectively) for the critical value of F are <u>4</u> and<u> 118 .</u>

Use the grouping method to factor the polynomial below completely 3x^3+9x^2+5x+15​
Tomtit [17]

Answer:

(x+3)( 3x^2 +5)

Step-by-step explanation:

3x^3+9x^2+5x+15​

Split into two groups

3x^3+9x^2     +5x+15​

Factor 3x^2 out of the  first group and 5 out of the second group

3x^2 ( x+3)  + 5(x+3)

Factor out x+3

(x+3)( 3x^2 +5)

What is the domain of the function f(x) = 2x /(3x^2− 3
Svet_ta [14]
The domain of the function in this case will be for when the denominator is different from zero:
 3x ^ 2- 3 = 0
 3x ^ 2 = 3
 x ^ 2 = 3/3
 x ^ 2 = 1
 x = + / - 1
 Therefore the domain of this function are all reals without including x = 1 and x = -1

Solve for x <br> 4x+3 X-8
Karo-lina-s [1.5K]
We know this angle is a 90° or a right angle. So another words we know adding these 2 expressions equals to 90°.

(4x + 3) + (x - 8) = 90°

Remove the parentheses and combine the like-terms:

5x - 5 = 90°

Add 5 on both sides:

5x = 95°

Divide 5 on both sides

x = 19

You answer is x = 19.
