Answer:

x=0

y=7

Step-by-step explanation:

Divide 6x-4y=-28 by -2..... -3x+2y=14

3x+5y=35

-3x+2y=14

--------------

7y=49

y=7

6x-4*7=-28

x=0

Find the standard deviation for the given sample data. Round your answer to one more decimal place than is present in the origin

Tema [17]

Answer:

s = 19.7

Step-by-step explanation:

First we need to calculate the mean x' of the sample as:

$x'=\frac{55+18+39+20+20+44+69}{7}=37.9$

We sum all the scores and divide them by the number of scores.

Then, the standard deviation s is calculated as:

$s=\sqrt{\frac{(55-37.9)^2+(18-37.9)^2+(39-37.9)^2+(20-37.9)^2+(20-37.9)^2+(44-37.9)^2+(69-37.9)^2}{7-1} }\\ s=19.7$

We square every score less the mean, sum every value, then divide that by the number of scores less 1 and finally, we calculate the square root.

So, the standard deviation of the sample is 19.7

the coordinates of three of the vertices of a parallelogram are given. Find the possible coordinates for the fourth vertex. L (0

frosja888 [35]

Answer:

Step-by-step explanation:

Given Coordinates of three vertices of the parallelogram L(0,4), M(6,0), N(2,4).

Corresponding to each vertex, there are three possibilities of having a fourth vertex

Coordinates of fourth vertex opposite to L is given by

(x,y)

(6+2−0,0+4−4)=(8,0)

Coordinates of fourth vertex opposite to M is given by

(x,y)=(0+2−6,4+4−0)=(−4,8)

Coordinates of fourth vertex opposite to N is given by

(x,y)=(0+6−2,4+0−4)=(4,0)

Therefore, the possible coordinates of the fourth vertex are

(8,0);(−4,8) and(4,0)
