The equation of the line in slope-intercept form is:

y = mx + b

Where,

m: slope of the line

b: cutting point with the y axis.

For the slope of the line we have:

m=\frac{y2-y1}{x2-x1}

Substituting values we have:

m=\frac{-4-8}{-6-4}

Rewriting we have:

m=\frac{-12}{-10}

m=\frac{6}{5}

Then, we choose an ordered pair:

(xo, yo) = (4, 8)

Substituting values in the generic equation of the line we have:

y-yo = m (x-xo)

y-8 = \frac{6}{5} (x-4)

Rewriting we have:

y = \frac{6}{5}x -\frac{24}{5} + 8

y = \frac{6}{5}x -\frac{24}{5} + \frac{40}{5}

y = \frac{6}{5}x + \frac{16}{5}

Answer:

The equation of the line in slope-intercept form is:

y = \frac{6}{5}x + \frac{16}{5}

Answer:

y = \frac{6}{5} x + \frac{16}{5}

Step-by-step explanation:

The slope-intercept form is y = mx + b, where "m" is the slope and 'b" is the y-intercept.

Given: G(-6, -4) and E(4, 8)

Now we can use these points G(-6, -4) and E(4, 8) and find the slope.

Slope (m) = \frac{y2 - y1}{x2 - x1}

Here x1 = -6, y1 = -4, x2 = 4 and y2 = 8

Plug in these values in the above formula, we get

slope(m) = \frac{8 - (-4)}{4 -(-6)}

= \frac{12}{10}

Slope (m) = \frac{6}{5}

Now we can use the formula (y - y1) = m(x - x1) and find the required equation.

We can plug in m value and (x1, y1) value and find the equation.

y - (-4) = 6/5(x - (-6))

y + 4  = 6/5(x + 6)

Using the distributive property a(b + c) = ab + ac, we get

y + 4 = 6/5 x + 36/5

y = 6/5 x + 36/5 - 4

y =6/5 x +(\frac{(36 - 20)}{5}

y = \frac{6}{5} x + \frac{16}{5}

One estimate of the population of the world on January 1, 2005, is
inn [45]

Answer:

8,566,379,470 people

Step-by-step explanation:

Let's start simple.  In order to find the population increase on January 1, 2006, we need to multiply 6,486,915,022 by 1.4% and add it to 6,486,915,022.

  1. 6,486,915,022*1.4% = 90,816,810.308
  2. 90,816,810.308+6,486,915,022 = 6,577,731,832.31 people on January 2006.

Note that the above two steps gives the same answer as 6,486,915,022*1.014.

So we need to do this for each year.  20 years pass between 1/1/2005 and 1/1/2025.  

We need to do 6,486,915,022*1.014*1.014*1.014... 20 times.

This is equivalent to 6,486,915,022*1.014^{20}.

Multiplying it out gives us 8566379470.2 = 8,566,379,470 people.

Heres a set of data 2.4, 1.6, 3.2, 0.3, 1.5 each peice of data is increases by 10, what is the mean? each new peice of data is d
Leviafan [203]

Step-by-step explanation:

Mean is the ratio of the sum of the sample data to the total sample size.

1) Given the set of data 2.4, 1.6, 3.2, 0.3, 1.5, if each piece of data is increases by 10, the new data's will be;

(10+2.4), (10+1.6), (10+3.2), (10+0.3), (10+1.5)

sum of the new data's = 59

Sample size = 5

Mean = 59/5

Mean = 11.8

Hence if the price of data is increases by 10, its new mean will be 11.8

2) If each new piece of data is doubles, the new set of data will be;

2(2.4), 2(1.6), 2(3.2), 2(0.3), 2(1.5)

= 4.8, 3.2, 6.4, 0.6, 3.0

Sum of new data = 4.8+3.2+6.4+0.6+3.0

Sum of new data = 18

sample size = 5

Mean = 18/5

Mean = 3.6

Hence the new mean if the data were doubles is 3.6
