1. Is the average change in population the same now as it was 50 years ago? Explain your answer.
2. Reflect on the interpretation of your data.
3. What should you consider when comparing population growth (or decline) over different intervals of time? Hint: What factors influence population growth or decline? Explain fully and provide examples where needed.
1. The average change in population is not the same now as it was 50 years ago. The population growth rate can vary greatly from year to year and decade to decade, and is influenced by a variety of factors such as birth and death rates, immigration, and emigration. Therefore, it is important to analyze the specific data for each time period to determine the average change in population.
2. When interpreting data on population growth or decline, it is important to consider the factors that influence population change and to analyze the data in the context of the specific time period being studied. It is also important to consider the accuracy and reliability of the data source, as well as any potential biases or limitations in the data.
3. When comparing population growth or decline over different intervals of time, it is important to consider a range of factors that can influence population change, such as birth and death rates, migration patterns, economic and environmental conditions, and government policies. For example, population growth rates in a country may be influenced by changes in healthcare access or advancements in technology that reduce infant mortality rates or increase life expectancy. In addition, migration patterns can greatly impact population growth rates, as some regions may experience large influxes of immigrants or emigrants at different periods in time. When comparing population data over different intervals of time, it is important to take into account these and other factors that may contribute to population growth or decline.

Answer:
SAMEEEE
Step-by-step explanation:
Use r = 2 and r = 5 to determine if the two expressions are equivalent.
r + 4(2 + r) – 12 8 + 2r – 6
Complete the statements.
When r = 2, the first expression is
.
When r = 2, the second expression is 6.
When r = 5, the first expression is 21.
When r = 5, the second expression is
.
The expressions are not equivalent.

The ratio of dye to pounds of clothing is constant. A worker develops the chart below to show the amount of dye needed for different amounts of clothing.
Clothes Dyeing
Weight of clothing (pounds)
Cups of dye
22
5.5
28
6.5
34
8.5
36
9
For which weight of clothing is the ratio of weight to dye different from the other ratios?
22 pounds
28 pounds
34 pounds
36 pounds
Answer:
28 pounds
Step-by-step explanation:
Ratios:
22:5.5
28:6.5
34:8.5
36:9
So you divide the ratios:
22/5.5 = 4
28/6.5= 4.30769230769
34/8.5=4
36/9=4
So 28 pounds is different from the other ratios
On an architect’s drawing of a house, 1 inch represents 1.5 feet. If the bedroom window is 5 inches long on the drawing, how many feet long will it be in the actual house?
Brainliest if you answer
Answer:
3.33~
Step-by-step explanation:
Since 1 inch represents 1.5 feet, you'll divide 5 inches by 1.5. And get 3.33 repeating
Answer:
7.5 feet
Step-by-step explanation:
REASONAccording to the given scale, 1 inch on the drawing represents 1.5 feet in the actual house.
Therefore, to find the length of the bedroom window in feet, we need to multiply the length on the drawing (5 inches) by the scale factor (1.5 feet/inch):
5 inches * 1.5 feet/inch = 7.5 feet
Hence, the bedroom window will be 7.5 feet long in the actual house.

Find X please show work!
Answer:
x=35
Step-by-step explanation:
The sum of the angles of the triangle is 180
x+10 + x + 3x-5 = 180
Combine like terms
5x +5 = 180
Subtract 5 from each side
5x+5-5= 180-5
5x = 175
Divide each side by 5
5x/5 =175/5
x=35
Answer:
35 is correct answer

A tent company has a tent design that is a triangular prism. The following is a net of the design.
Note: Figure is not drawn to scale.
If a = 67 inches, b = 68 inches, c = 40 inches, and d = 64 inches, how much fabric is needed to make the tent?
Answer:
first...you have to split the net into three rectangles and two triangles
picture inserted
Step-by-step explanation:
step 1
triangular base area
1/2 bh = 1/2 (44 in)(64 in)
= 1/2 (2,816 sq in)
= 1,408 sq in.
2 x 1,408 sq in = 2,816 sq in.
step 2
end rectangle area
lw = (68 in)(69 in)
= 4,692 sq in
2 x 4,692 sq in = 9,384 sq in
Now find the area of the middle rectangle
lw - (69 in) (44 in) = 3,039 sq in.
then add all the areas together
2,816 + 9,384 + 3,036 = 15,236 sq in

Write 7^3 x 7^2 using a singular exponent.
Answer:
7^5
Step-by-step explanation:
The base number (7) is the same, so we can just add the exponents together.
Hope that helped!
To write 7^3 x 7^2 using a singular exponent, you can add the exponents together since the bases (7) are the same. The result is:

Suppose that f(x)=4x+5. What is f^-1 (f^-1(9)) ?
Step-by-step explanation:
the inverse of the inverse of a function is the function itself
It's like going and coming back
f^-1(f^(-1)9) = f(9) f(9) = 4*9+5f(9) = 36+5 f(9) = 41Answer:
9
Step-by-step explanation:
The inverse of the inverse is the input
f^-1 (f^-1(9)) = 9
As a proof
f(x) = 4x+5
y = 4x+5
Exchange x and y
x = 4y+5
Solve for y
(x+5) = 4y
(x+5)/4 = y
f^-1 (x) = ( x-5)/4
Then find the inverse of this function
y = ( x-5) /4
Exchange x and y
x = (y-5)/4
4x = y-5
4x+5 = y
Which gives us the original function back
f^-1( input) = 4x+5
Using the value given
f^-1 (9) = ( 9-5)/4=4/4 =1
Using the 1 from the previous part as the input
f^-1( 1) = 4*1+5 = 4+5 = 9

Answer: 1. sqrt(19); 2. sqrt (96); 3. sqrt (105); 4. sqrt (28)
Step-by-step explanation: All you have to do is use Pythagoras' Theorem.
So, e.g. in question 1, the equation would be x^2 + 9^2 = 10^2.
x^2 = 100 - 81
x^2 = 19
Therefore, x = sqrt (19) or (19)^1/2
BTW, sqrt means square root.
And now you apply it for everything else.

Order the numbers from closest to zero to farthest from zero:
4.38, l4.5l, l-4.6l, -l4.9l
HELPPPPP
The smallest number is the one closest to zero, or after zero, if it's a negative number, while the largest number is the number with the largest difference from the smallest, or the highest of value (not considering all situations). Usually, you would use the ascending order method for graphing numbers based on their value, which is indeed smallest to largest. According to thefreedictionary.com, "A function or variable continuously approaching zero as a limit." Tip: In ordering numbers based on value, the whole numbers that aren't negative are considerably believed to be the easiest numbers to order.
With that being said, here is the order of the numbers from smallest to largest:
4.38
4.5
4.6
4.9
Answer:
Here are the numbers ordered from closest to zero to farthest from zero:
4.38 (closest to zero)
4.5
-4.6
-4.9 (farthest from zero)

Explain the cosine rule and sine rule while also saying how to use it and provide examples (keep it in simple terms)
Answer:
Sure, I'll explain the cosine rule and sine rule in simple terms:
The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.
Here's an example of how to use the cosine
Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.
Using the cosine rule:
a^2 = b^2 + c^2 - 2bc * cosA
where A is the angle opposite side a, we can plug in our values and solve for a:
a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)
a^2 = 64 + 36 - 96 * 0.707
a^2 = 10.56
a = sqrt(10.56)
a = 3.25 (rounded to two decimal places)
Therefore, the length of side a is approximately 3.25 units.

The mean for the data set is 15. What number is missing?
18,16, __,9,12,23
Answer:
12
Step-by-step explanation:
\(\frac{18 + 16 + 9 + 12 + 23 + x}{6} = 15\)
x = 90 - (18 + 16 + 9 + 12 + 23 )
x = 12
Hello answer 12
18 + 16 + 12 + 9 + 12 + 23 = 90 90 ÷ 6 = 12 therefore the missing number is 12 because when you add all the numbers amd divide by the numbers of number you get 15
