Use the fact that the world population was 2,560 million in 1950 and 3,040 million in 1960 to model the population of the world

Serga [27]

Answer:

The relative growth rate is 18.75%.

Step-by-step explanation:

If the world population was 2.560 million in 1950 and 3.040 million in 1960, it means that there was a growth of 480 million people in 10 years. Thus, it is a growth of 18.75%, according to the following calculation:

2,560 = 100

480 = X

(480 x 100) / 2,560 = X

48,000 / 2,560 = X

18.75 = X

Therefore, if this growth rate were to be maintained, in subsequent years the world population would evolve as follows:

1970: 3,040 x 1.1875 = 3,610 million inhabitants

1980: 3,610 x 1.1875 = 4,286 million inhabitants

1990: 4,286.8 x 1.1875 = 5,090 million inhabitants

Kanesha wants to find out if people in her community would support turning an unused park into a dog park. Which populations wou

inysia [295]

The most likely populations that Kanesha can pick an appropriate sample for the survey is: people who live near the unused park.

When running a survey, it is important to use a sample that represents the target population that can sufficiently provide answers to the questions you seek to ask.

Using the a sample from the right population will give you enough data to carryout a survey. The people living close to the unused park would definitely be affected by whatever establishment that is done in the unused park.

Therefore, the most likely populations that Kanesha can pick an appropriate sample for the survey is: people who live near the unused park.

Parallelogram MNPQ was dilated to create parallelogram M'N'P'Q'. On a coordinate plane, 2 parallelograms are shown. Parallelogra

Naddika [18.5K]

Answer:

The answer is below

Step-by-step explanation:

Which statements are true about the parallelograms? Check all that apply.

The length of side MN is 2 units.

The length of side M'N' is 5 units.

The image is smaller than the pre-image.

Sides MQ and M'Q' both have the same slope, 1.

The scale factor is 2/5

a) The length of side MN is determined using the formula:

$|MN|=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}=\sqrt{(4-2)^2+(-2-(-2))^2}=\sqrt{2^2}=2\\ \\ |MN|=2$

The first option is correct

b) The length of side M'N' is determined using the formula:

$|M'N'|=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}=\sqrt{(10-5)^2+(-5-(-5))^2}=\sqrt{5^2}=2\\ \\ |M'N'|=5$

The second option is correct

c) From the coordinates of parallelogram MNPQ and M'N'P'Q', we can see that parallelogram MNPQ is dilated by a factor of 5/2 to produce parallelogram M'N'P'Q' , hence parallelogram M'N'P'Q' is bigger that parallelogram MNPQ. This means that The image is bigger than the pre-image.

The third option is wrong

d) The slopes are given as:

$Slope\ of\ MQ=\frac{Change\ in\ y}{Change\ in\ x}=\frac{1-2}{-3-(-2)} =1\\ \\Slope\ of\ M'Q'=\frac{Change\ in\ y}{Change\ in\ x}=\frac{3-5}{-7-(-5)} =1\\$

Option four is correct

e) From the coordinates of parallelogram MNPQ and M'N'P'Q', we can see that parallelogram MNPQ is dilated by a factor of 5/2 to produce parallelogram M'N'P'Q', hence the scale factor is 5/2

Option 5 is wrong
