Find the gfc of 24m and 16mn

In a simple regression analysis for a given data set, if the null hypothesis β = 0 is rejected, then the null hypothesis ρ = 0 i

kati45 [8]

Answer:

Null hypothesis: $\rho =0$

Alternative hypothesis: $\rho \neq 0$

The statistic to check the hypothesis is given by:

$t=\frac{r \sqrt{n-2}}{\sqrt{1-r^2}}$

And is distributed with n-2 degrees of freedom

And the statistic to check the significance of a coeffcient in a regression is given by:

$t_1 = \frac{\hat{\beta_1} -0}{S.E (\hat{\beta_1})}$

For this case is importantto remember that t1 and p value for test of slope coefficient is the same test statistic and p value for the correlation test so then the answer would be:

Always

Step-by-step explanation:

In order to test the hypothesis if the correlation coefficient it's significant we have the following hypothesis:

Null hypothesis: $\rho =0$

Alternative hypothesis: $\rho \neq 0$

The statistic to check the hypothesis is given by:

$t=\frac{r \sqrt{n-2}}{\sqrt{1-r^2}}$

And is distributed with n-2 degrees of freedom

And the statistic to check the significance of a coeffcient in a regression is given by:

$t_1 = \frac{\hat{\beta_1} -0}{S.E (\hat{\beta_1})}$

For this case is importantto remember that t1 and p value for test of slope coefficient is the same test statistic and p value for the correlation test so then the answer would be:

Always

Carl worked six and one-half hours on Monday. He worked eight and two-third hours on Tuesday. How many hours did Carl work in al

Gnoma [55]

Answer: 15 hours and 37 minutes

Step-by-step explanation: 6 and 1/2 hours is 6 hours and 30 mins

8 and 2/3 hours is 8 hours and 67 mins

So 8 hours + 6 hours is 14 hours

Since 67 minutes is over an hour, we're going to take 60 minutes from 67, leaving u with 7 minutes

Add the 60 minutes to the 14 hours and you get 15 hours.

Take the 7 minutes and add it to the 30 minutes and you get 37 minutes.

All together the answer is 15 hours and 37 minutes

A Fraction Number: The sum of the numerator and denominator is 40. if its value is 3/5 after simplifying, what is the fraction b

katrin2010 [14]

Here: Fraction = 3/5
Let, original fraction (before simplifying) = 3x/5x
Then, 3x + 5x = 40
8x = 40
x = 40/8
x = 5

So, 3x = 3(5) = 15 & 5(5) = 25

In short, Your Answer would be 15/25

Hope this helps!

Dan drove 845 miles in 13 hours. At the same rate, how many miles would he drive in 11 hours

denis23 [38]

845 miles / 13 hours = 65 miles per hour

65 miles per hour x 11 hours = 715 miles

A cab driver charges a fixed rate of $3 plus an additional $1.50 for each mile driven. When representing this situation with a f

Andreas93 [3]

The independent variable would be the fixed rate of $3 because the amount for each mile driven changes based on how far they drive
