Answer:

The system of equations has infinite solutions. True for all y and x.

Given equations:

x + 4y = 0

20y = - 5x

Make x the subject for equation 1:

x + 4y = 0

x = -4y

Plug x as -4y in second equation:

20y = - 5x

20y = - 5(-4y)

20y = 20y

0 = 0

L.H.S = R.H.S

True for all y.

Therefore true for all x.

Answer:

x=1   y=(-1/2)   putting those in 20x1=20   so 20= then you put -1/2 and multiply it by the -5  that would be your answer

Which equation is correct for the perpendicular bisector of the line segment whose endpoints are (−1,1) and (7,−5)?
kherson [118]
Slope = (-5-1)/(7+1) = -6/8 = -3/4
Perpendicular slope = 4/3

Midpoint = ((-1+7)/2 , (1+(-5))/2) = (3, 3)

equation:
y = mx + c
y = 4/3 x + c

at point (3, 3)
3 = 4/3(3) + c
c = 3 - 4 = -1

y = 4/3 x - 1 or 3y = 4x - 3

Answer

standard deviation

Explanation

Standard deviation is the measure of spread of data around the mean.

Mode is the most common value - which would be the mean in a normal-like distribution.

Median is the middle value when the data is ranked in ascending order (or descending even)

Skewness, is when the mode of the data falls behind the mean by a large margin.

An example is GDP, a few billionaires increase the number number and distort it, even though most people are of low or middle based income.

A population of geese grow in such a way that each generation is simply 2.2 times the previous generation. There were 3 geese in
lapo4ka [179]
First generation: 3

Second generation: 3\times2.2

Third generation: 3\times2.2\times2.2=3\times2.2^2

Fourth generation: 3\times2.2\times2.2\times2.2=3\times2.2^3

And so on. The general formula for the nth generation is 3\times2.2^{n-1}. So by the 15th generation, you should expect around 3\times2.2^{15-1}\approx186655 geese.
