Determine whether the results below appear to have statistical significance, and also determine whether the results have practi

pantera1 [17]

Answer:

Step-by-step explanation:

Given that in a study of a weight loss program, 4 subjects lost an average of 48 lbs.

It is found that there is about a 32% chance of getting such results with a diet that has no effect.

The results do not appear to have statistical significance. The reasons are

1) Sample size of 4 is very small not even meeting the bare minimum

2) Sample of 4 cannot be taken to represent the population

3) Whether bias was there in the selection of sample is not known.

4) Std deviation is not considered which is very important while concluding results.

Answer:

$2x^6$

Step-by-step explanation:

First, we find the greatest common factor 50, 10 and 2.

It is 2.

Then, we find the greatest common factor of $x^{6},x^{7}$ and $x^{8}$ which is $x^{6}$ .

Thus, the greatest common factor is $2x^6$

Find the average rate of change between f(-7) and f(-1) in the function f(x)=x^2+2x -8

Levart [38]

Answer:

- 6

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

$\frac{f(b)-f(a)}{b-a}$

here [ a, b ] = [ - 7, - 1 ]

f(b) = f(- 1) = (- 1)² + 2(- 1) - 8 = 1 - 2 - 8 = - 9

f(a) = f(- 7) = (- 7)² + 2(- 7) - 8 = 49 - 14 - 8 = 27

Hence

average rate of change = $\frac{-9-27}{-1-(-7)}$ = $\frac{-36}{6}$ = - 6
