Answer:

d. 0.133

Step-by-step explanation:

-Standard error is calculated using the formula:

$E=\frac{\sigma}{\sqrt{n}}\\\\\sigma-=standard \ deviation\\n=sample \ size$

#We substitute the given values in the formula to solve for E:

$E=\frac{\sigma}{\sqrt{n}}\\\\=\frac{1.2}{\sqrt{81}}\\\\=0.133$

Hence, the standard error is 0.133 and the correct option is d

Part of a shape is drawn.

frosja888 [35]

Answer:

The points of the rotated shape are: (4, 1), (5, 3), (4, 4), (2, 1), (1, 3), (2, 4)

Step-by-step explanation:

From the part of the shape we can see and the symmetry, the missing points are:

(-2, -1)

(-1, -3)

(-2, -4)

Rotation 180° about the origin transforms the point (x, y) into (-x, -y). Applying this rule to our figure, we get:

(-4, -1) -> (4, 1)

(-5, -3) -> (5, 3)

(-4, -4) -> (4, 4)

(-2, -1) -> (2, 1)

(-1, -3) -> (1, 3)

(-2, -4) -> (2, 4)

A line contains the points (-7,15) and (10,27) what is the slope of the line as a simplified fraction?

Gwar [14]

Answer:

The slope of line for given points is $\frac{12}{17}$

Step-by-step explanation:

Given points of line as :

A = ( - 7 , 15 ) i, e $x_1$ = - 7 , $x_1$ = 15

B = ( 10 , 27 ) i.e $x_2$ = 10 , $y_2$ = 27

Let The slope of line be m

So , The slope with two points is given as equation

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

Or, m = $\frac{27 - 15}{10 + 7}$

Or, m = $\frac{12}{17}$

Hence The slope of line for given points is $\frac{12}{17}$ . Answer
