Take 1960 as 0 then find out next year's

1970=10
1980=20
1990=30
2000=40
2005=45
2010=50

Also

Divide each population by one thousand i.e turn to decimal .

This we done to create the plot on graph easily

The graph has been attached

for the below points

(0,9.706)
(10,10.652)
(20,10.798)
(30,10.847)
(40,11.353)
(45,11.478)
(50,11.576)

Answer:

When creating a scatter plot, first decide the explanatory variable and response variable.

<u>Explanatory variable</u> (independent variable) is along the x-axis.

<u>Response variable</u> (dependent variable) is along the y-axis.

The population number is dependent upon the year, therefore, draw the year along the x-axis and the population along the y-axis.

As the data values for the population start at 9706 thousand, it is sensible to begin the y-axis at 9000.

As the data values for the year start at 1960, it is sensible to begin the x-axis at 1950.

An appropriate x-axis : y-axis scale to use is 1 : 50

Plot the data points according to the given in the table.
Finally, add a title for each axis.

The graph means that 2 x and 9.4 make up 20 in total, so set up the equation 2x + 9.4 = 20.

Subtract 9.4 from both sides.

2x = 10.6

Divide by 2.

x = 5.3

The answer is the value of x that makes this equation true is 5.3

Hope this helps

Simplify (x - y + 1) - (x + y - 1)

andrey2020 [161]

First, distribute the minus sign across the second set. So you have:

x - y + 1 - x - y + 1

Now, we combine like terms:
x-x=0
-y-y=-2y
1+1=2

So we have -2y+2

Hope that helps.

help please!! find the area of each triangle. round intermediate values to the nearest tenth. use the rounded values to calculat

White raven [17]

Area of a triangle = (1/2)*base*height

For both of the triangles, you have the base (8.8 for the triangle on the left, 7.6 for the triangle on the right) and the side lengths, but not the height. But since both are isosceles triangles, you can find the height using the pythagorean theorem.

First divide the triangle vertically into two triangles (see attached picture). Now you have two right triangles, you can apply the pythagorean theorem on either one of them to find the height. The pythagorean theorem says that for a right triangle, $a^2+b^2=c^2$ , where c is the hypotenuse and a and b are the sides of the triangle.
