What is the critical value t* which satisfies the condition that the t distribution with 14 degrees of freedom has probability 0
Oduvanchick [21]

Answer:

t_{0.35,14}= 0.3933306

Step-by-step explanation:

From the question we are told that:

Degree of freedom df=14

Significance Level \alpha=0.35

Generally the expression for critical value t is mathematically given by

  t_{\alpha,df}

  t_{0.35,14}

Therefore From Students T Value Table

 t_{0.35,14}= 0.3933306

 T-Value (right-tailed): 0.3933306

Factor 125x9 64. (5x3 – 4)(25x6 20x3 16) (5x3 – 4)(25x3 20x3 16) (5x3 4)(25x6 – 20x3 16) (5x3 4)(25x3 – 20x3 16).
MatroZZZ [7]

The factorization of \rm 125x^9 + 64 is  \rm (5x^3 + 4)(25x^6 - 20x^3 +16).

<h3>Factorization;</h3>

Factorization is nothing but writing a number as the product of smaller numbers.

Given

Polynomial; \rm 125x^9 + 64

To find the factorization the polynomial equates the equation with zero following all the steps given below.

Then,

The factor of the polynomial is;

\rm= 125x^9 + 64\\\\= 125x^9 -100x^6+80x^3+100x^6-80x^3+64 \\\\ =5x^3(25x^6 - 20x^3 +16) +4(25x^6 - 20x^3 +16) \\\\=(5x^3 + 4)(25x^6 - 20x^3 +16)

Hence, the factorization of \rm 125x^9 + 64 is  \rm (5x^3 + 4)(25x^6 - 20x^3 +16).
