Answer:

105°

Step-by-step explanation:

(11x-5)+(6x+5)+x=180

If sample variance is computed by dividing SS by df = n – 1, then the average value of the sample variances from all the possibl
boyakko [2]

Answer:

s^2 = \frac{SS}{n-1}

And if we take the average value of the sample variances from all the possible random samples we will get the population variance:

\sigma =\frac{SS}{n}

So then the best answer for this case would be:

The average value of the sample variances from all the possible random samples will be exactly the population variance

Step-by-step explanation:

For this case we can define the sum of squares with this formula:

SS = \sum_{i=1}^n (X_i -\bar X)^2

Where:

\bar X =\frac{\sum_{i=1}^n X_i}{n}

And we can find the sample variance with this formula:

s^2 = \frac{SS}{n-1}

And if we take the average value of the sample variances from all the possible random samples we will get the population variance:

\sigma =\frac{SS}{n}

So then the best answer for this case would be:

The average value of the sample variances from all the possible random samples will be exactly the population variance

Ms. Etienne deposited $450 into an account that paid 5% interest compounded annually. She did not make any
Alexus [3.1K]

Answer:

$603.04

Step-by-step explanation:

The Compound Amout formula is A = P(1 + r)^t, where:

P is the principal (initial deposit), r is the annual interest rate as a decimal fraction, and t is the time period in years.

In this particular case, the Compound Amount is:

A  = ($450)(1 + 0. 05)^6 = ($450)(1.34) = $603.04

A line passes through (1, -5) and (-3, 7).
siniylev [52]

Answer:

Slope-intercept form: y=-3x-2

Point-slope form: y+5=-3(x-1)

Step-by-step explanation:

Slope-intercept form is y=mx+b

Point-slope form is y-y1=m(x-x1)

The slope is (7-(-5))/(-3-1)=12/-4=-3

Now we solve for b, aka. the y-intercept:

-5=-3(1)+b

-5=-3+b

-2=b

So the equation in slope intercept form is y=-3x-2

As for point-slope form, it's y+5=-3(x-1)
