When figuring the pooled population variance estimate in a t test for independent means?

1 answer:

4 0

The appropriate response is a weighted average. It is a mean ascertained by giving qualities in an informational index more impact as indicated by some characteristic of the information. It is normal in which every amount to have arrived at the midpoint of is allocated a weight, and these weightings decide the relative significance of every amount on the normal.

Lie is solving the quadratic equation by completing the square.

wel

we have

$3x^{2} + 18x - 8 = 0$

Step $1$

Move the constants to the right side

$3x^{2} + 18x = 8$

Step $2$

Factor 3 out of the variable terms

$3(x^{2} + 6x) = 8$

Step $3$

Add $27$ to both sides of the equation

$3(x^{2} + 6x+9) = 8+27$

$3(x^{2} + 6x+9) = 35$

Step $4$

Write the polynomial as a binomial squared

$3(x+3)^{2} = 35$

therefore

the answer is

Factor 3 out of the variable terms.

What property was used on 14k + 2 (3k+5) -5 = 10 to obtain 14k + 6k +10 - 5 =10

Elis [28]

$\boxed{\text{The distributive property}}\\\\\text{In order to solve the equation, you would have to first use the }\\\text{distributive property:}\\\\14k + 2 (3k+5) -5 = 10\\\\\text{Distribute the 2 to the variables inside the parenthesis}\\\\14k+6k+10-5=10\\\\\text{You can see that your outcome matches the equation in the question}\\\\\text{Therefore, the distributive property would be your answer}$
