1. How much did the population change between 1950 and 1960? What was the average annual change for that period? Hint: Calculate the changes, then calculate the mean, or average, by dividing by the number of years. State the units clearly. The units are listed on the chart.

2. Repeat question 1 for the period between 1970 and 1980; between 1990 and 1995.

3. Do you think a linear model (or graph) would best illustrate this data? Explain your reasoning.

Answer:

16.49

Step-by-step explanation:

First we are going to find the area of the larger circle. You don't need to find the radius, you can just use the diameter(the radius is 2.5). 3.14 times 2.5 squared=19.63. Next, the radius of the smaller circle is 1. So, 3.14 ^1 squared=3.14 19.63 - 3.14= 16.49

Answer:

280ml of oil.

Step-by-step explanation:

The first step to finding how much oil he should use, turn 5 : 2 into a fraction.

5     Since we know he uses 700ml of mayo, we use that to find the          

2     amount of oil.

We use cross multiplication and use x for the amount of oil.

x = oil

5  =   700

2         x

2 x 700 = 1,400

1,400 ÷ 5 = 280

x = 280

In order to confirm if this is true, we check if the ratios are equivalent.

5/2 = 700/280

simplify 700/280 by finding the gcf

GCF = 140

700 ÷ 140 = 5

280 ÷ 140 = 2

5 : 2 or 5/2

Therefore, it is correct

Answer:

86,205.3 cm³

Step-by-step explanation:

So first you have to know the formulas. The volume of a cone is V= 1/3 π r²×H. The volume for a sphere is V= 4/3πr³. But, in this instance the sphere is cut in half, so what we would do is just divide the formula by 2. We are going to start with the cone. plug in the answers. r=28 and H=49. you can always, for pie, plug it in for 3.14, depending on your calculator and teacher. It should look like V=1/3π28²×49. So, for that answer you should get, 40,229.14cm³. Next is the half sphere. Plug in what is necessary, r=28. It should look like, V=4/3π28³. You should get 91952.32cm³, but remeber you have to half it so takes that answer and divde by 2. Then your answer is 45976.16cm³. After done just add your two sums together and you should get 86205.3cm³.

Answer:

90 degrees is a right angle, and is in the corner of this text box, or this: |_

40 degrees is an acute angle, a little less than half 90 degrees, like this: <

135 degrees is an obtuse angle, and is 90 degrees + 45 degrees.

Also, something important to remember when drawing this is that 180 degrees is half of a circle, and 360 degrees is a full circle.

Answer:

A = 324m²

Step-by-step explanation:

Formula for finding the surface area of a rectangular prism:

2(wl + hl + hw)

First, let's find out which one of the measurements is the height, length, or width.

6m = length

16m = width

3m = height

Next, we calculate the surface area. We have to do the formula one by one too.

2(wl + hl + hw)

2(16x6 + 3x6 + 3x16)

16 x 6 = 96

3 x 6 = 18

3 x 16 = 48

Now, we add those together.

96 + 18 + 48 = 162

Lastly, multiply by 2.

162 x 2 = 324

Therefore, A = 324m²

Answer: 49.2 yd 2

Step-by-step explanation:

You must know the formula for surface area. The surface area would be A=2(wl+hl+hw), Plug in the numbers, and then solve. You will get 49.2.

Answer:

0.484 billion       0.0484 billion per year

Step-by-step explanation:

Population change between 1950 and 1960 = 3.039 - 2.555 = 0.484 (billion)

Number of years between 1950 and 1960 = 1960 - 1950 = 10 years

Average population change per year = 0.484 ÷ 10 =  0.0484 billion per year

Answer:

Step-by-step explanation:

The 1960 Census of Population is providing a vast amount of detailed statistics reflecting the widespread redistribution of the population during the 1950's. The pattern of population movement during the 1950's parallels, to a great extent, that which occurred during the 1940's, particularly after World War II. To permit better understanding of the population movement, that has occurred from 1950 to 1960, the Bureau of the Census has undertaken the compilation of statistics on the separate components of population change for counties. This is the first time that, estimates of net migration have ever been published for all the counties in the United States. By combining groups of counties into certain widely used statistical areas, such as the standard metropolitan statistical area, State economic area, and economic subregion, one can obtain a broader picture of population movement in the United States.

The histogram of the given data is attached. A histogram is a graphical representation of the distribution of numerical data. It consists of a set of rectangles, or bins, placed side by side along a horizontal axis.

The width of each bin in the histogram represents a range of values, and the height of each bin represents the frequency or count of data points that fall within that range.

Histograms are commonly used to visualize the shape of a data distribution, including its center, spread, and any outliers or gaps. They can also reveal patterns or trends in the data, such as skewness, bimodality, or multimodality.

Histograms are often used in statistics, data analysis, and scientific research to explore, summarize, and communicate information about datasets. They are a powerful tool for understanding and interpreting numerical data, and can help to identify important features or insights that might be missed by other types of visualizations.

Answer:

Step-by-step explanation:

im assuming you solve for r.

-8r<-12

divided by -8 on both sides so you change signs

r>12/8

r> $ 3/2

Answer:

$r > 1.5$ or [tex]\frac{3}{2}[/tex]$

Hope this helps!

Step-by-step explanation:

Hiding the dollar signs real quick:

-8r < -12

Divide both sides by -8: ( remember that when multiplying or dividing both sides by a negative number reverses the inequality )

-8 ÷ -8 × r < -12 ÷ -8  =  r > 1.5 or [tex]\frac{3}{2}[/tex]

20 it's because you will take the w (width) and l (length) which is w=5

and l=4 and the answer is l x w so 5 x 4 = 20
