Complete the point-slope equation of the line through (-1,6)(−1,6)left parenthesis, minus, 1, comma, 6, right parenthesis and (1

velikii [3]

Answer:

$y-6 = -\frac{1}{2} (x+1)$

Step-by-step explanation:

For this case we have two points given (-1,6) and (1,5)

And we want to complete the point slope equation of the line:

$y-6 = m(x-x_o)$

We need to find the slope and we can use the following formula:

$m = \frac{y_2 -y_1}{x_2 -x_1}$

And replacing the info we got:

$m= \frac{5-6}{1-(-1)}=-\frac{1}{2}$

And then the equation would be given by:

$y-6 = -\frac{1}{2} (x- (-1))$

And our final answer would be:

$y-6 = -\frac{1}{2} (x+1)$

For a sample of n = 36 that has a sample variance of 1,296, what is the estimated standard error for the sample? 6 37 36 6. 9

Liula [17]

The estimated standard error for the sample is 6

Given,

Sample size, n = 36

Sample variance, $s^{2}$ = 1296

Standard deviation, s = √1296

= 36

Standard error, SE = $\frac{s}{\sqrt{n} }$

= $\frac{36}{\sqrt{36} }$

= $\frac{36}{6}$

= 6

Concept

Sample size is the number of participants or observations included in a study. It is denoted by ‘n’

Sample variance is a measure of the degree to which the numbers in a list are spread out. It is denoted by ' $s^{2}$ '

Standard deviation is a measure of how dispersed the data is in relation to the mean. It is denoted by ‘s’

What if you quadruple the radius of a circle. What happens to the circumference? Explain using examples.

Stells [14]

Step-by-step explanation:

Let's check

Let radius be x

Circumference:-

➜2πr

➜2πx

New radius=3x

New Circumference:-

➜2πr

➜2π3x

➜6πx

Taking ratio:-

➜2πx/6πx

➜1/3

➜1:3

If we quadruple the radius Circumference will also be quadrupled.
