The vertices of a triangle are P(–8, 6), Q(1, –3), and R(–6, –3). Name the vertices of

xz_007 [3.2K]

The refrection of a point or set of points across the line y = x will result in a point or set of points whose coordinates are the interchange of the x-value and the y-value of the original point or set of points.

Given that the vertices of a triangle are P(-8, 6), Q(1, -3) and R(-6, -3), the vertices of the triangle formed by the refrection Ry=x(ΔPQR) are P'(6, -8), Q'(-3, 1) and R'(-3, -6).

Find the mean and the standard deviation for each set of values. Show your work. 15,17,19,20,14,23,12

vekshin1

1. Mean.

$\overline{x}=\dfrac{15+17+19+20+14+23+12}{7}=\dfrac{120}{7}\approx\boxed{17.14}$

2. Standard deviation.

First we have to square each value and calculate the mean of that squares:

$\overline{x^2}=\dfrac{15^2+17^2+19^2+20^2+14^2+23^2+12^2}{7}=\boxed{\dfrac{2144}{7}}$

so the variance:

$s^2=\overline{x^2}-\overline{x}^2=\dfrac{2144}{7}-\left(\dfrac{120}{7}\right)^2\approx\boxed{12.41}$

and the standard deviation:

$s=\sqrt{s^2}=\sqrt{12.41}\approx\boxed{3.52}$

Write an standard form of: slope=-10/3 , y-intercept=5

rodikova [14]

Answer:

Input work is the work done on a machine as the input force acts through the input distance. This is in contrast to output work which is a force that is applied by the body or system to something else. Output work is the work done by a machine as the output force acts through the output distance.Jan 15, 2020 bshdggxgxgx xysfshsfsvsydvfnshdgdbdycbd dgd dh dgx dgx d

Solve 7x - c=k for x

kobusy [5.1K]

Answer:

$x = \frac{c+k}{7}$

Step-by-step explanation:

We'd add c in both sides

7x = c + k

Divide 7 in both sides isolate the variable

7x/7 = x

c+k/7

x = c + k/7

Our answer is x = c+k/7
