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

What is the solution to this system of equations? 2t + w = 10 4t = 20 − 2w A. It has no solution. B. It has infinite solutions.

joja [24]

Answer:

<h3>B. It has infinite solutions</h3>

Step-by-step explanation:

Given the system of equations:

2t + w = 10 ..... 1

4t = 20 − 2w ... 2

From 1:

w = 10-2t ...3

Substitute 3 into 2 to have;

4t = 20 - 2(10-2t)

4t = 20-20+4t

4t = 4t

Let t = k

Substitute t = k into 1 and get w;

From 1: 2t + w = 10

2k + w =10

w = 10 - 2k

k can take any integers. This shows that the solution to the equation is infinite

Find the area of a circle with a diameter of 16 inches. Use 3.14 for pi.

Aliun [14]

Diameter of the circle = 16 inches
Radius of the circle = 16/2
= 8 inches
pi = 3.14
Then
Area of the circle = pi (Radius)^2
= 3.14 * (8)^2
= 3.14 * 64
= 200.96 square inches
From the above deduction, it can be concluded that the correct option among all the options that are given in the question is the third option or option "c". I hope that this is the answer that you were looking for and the answer has come to your help.

A relation is plotted as a linear function on the coordinate plane starting at point e (0, 27)(0, 27) and ending at point f (5,−

kolbaska11 [484]

The slope of the line is calculated using
y2 - y1 / x2 - x1
Substituting the given values
-8 - 27 / 5 - 0 = -7
The rate of change or the slope is -7
And the initial value is the value of y when x is 0. From the first coordinates, the initial value is 27.

A high school runs a survey asking students if they participate in sports. The results are found below. Run an independence test

Sveta_85 [38]

Answer:

It can be concluded that participation in sports is dependent on grade level.

Step-by-step explanation:

In this case a Chi-square independence test for the data is to be performed at α = 0.01.

The hypothesis can be defined as follows:

H₀: The participation in sports is independent of grade level.

Hₐ: The participation in sports is dependent of grade level.
