A newspaper writer will write an article about the mean age of voters. She will estimate by selecting a sample of voters and calculating their mean age. Which method should the writer use to select the sample?randomly select 100 people who voted in the last election
select 100 people who voted in the last election and are more than 30 years old
select 100 people who voted for the most popular candidate in the last election
randomly select 100 people who read the newspaper
Answers
This will avoid bias based on age, as we would see in the second choice. It will also ensure that the people who respond are actually voters, unlike the last choice; some people that read the newspaper may not be voters at all. Additionally, some candidates are more popular among certain age groups, so to avoid bias we should not select just voters that voted for the most popular candidate.

Melanie’s bedroom walls are 45% painted. The area of her walls totals 420 square feet. What is the number of square feet of Melanie’s walls that still need to be painted?
Answers
You can get that by find out what 45% of 420 is (420 x 45 = y, divide it by 100), and subtracting it from 420 (420 - 189 = 231).
Or you can go right ahead and calculate what is the remaining percentage, which is 55%, so (420 x 55 = y, divide it by 100).
The percentage of Melanie's walls that still needed to be painted is 55 % and the number of walls is 231 feet²
What is Percentage?A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.
Percentage change is the difference between the measured value and the true value , as a percentage of the true value
Percentage change =( (| Measured Value - True Value |) / True Value ) x 100
Given data ,
Let the percentage of Melanie's walls that still needed to be painted be A
Now , the equation will be
The total number of walls = 420 feet²
The percentage of Melanie's walls that are painted = 45 %
So , the remaining percentage A = 100 - percentage of Melanie's walls that are painted
The percentage of Melanie's walls that still needed to be painted A = 55 %
And , the number of walls that needed to be painted = percentage of Melanie's walls that still needed to be painted A x total number of walls
On simplifying , we get
The area of walls that needed to be painted = ( 55/100 ) x 420
The area of walls that needed to be painted = 231 feet²
Hence , the area of Melanie's wall to be painted is 231 feet²

What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b, will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
The ratio is the division and the ratio can be bigger than the amount which is put on the ratio or the ratio could be smaller than the amount which is put on the ratio. It depends upon whether the numerator is big or small than the denomintor.
Given the condition in the question let's suppose the number is x then
seven-time is 7x and 5 means 7x + 5.
Similarly -2 times means -2x and 11 means -2x + 11 hence (7x +5 )/(-2x+11) will be correct answer.

Answers
You have to assume something or it is unsolvable.
We will assume that the triangle is divided into 2 smaller right triangles. They will be subject to a^2 + b^2 = c^2
a = 32/2 = 16
b = h
c = 20
20^2 = 16^2 + h^2
400 = 256 + h^2 Subtract 256
400 - 256 = h^2
144 = h^2
h = sqrt(144)
h = 12
Now we can find the area.
h = 12
base = b = 32
Area = 1/2 * b * h
Area = 1/2 * 32 * 12
Area = 192 square inches.
Problem 5
Same assumption. Same method.
a^2 + b^2 = c^2
c = 25
b = 7
h = ???
h^2 + 7^2 = 25^2
h^2 + 49 = 625
h^2 = 625 - 49
h^2 = 576
h = sqrt(576)
h = 24
Area = 1/2 Base * h
base = 2*7
base = b = 14
Area = 1/2 * 14 * 24
Area = 168 <<<< answer.
which function grows at the fastest rate for increasing values of x?

If you want to see this in action, make up a table of values. You'll see the y values for 2^x get very large and eventually need scientific notation
Hoped this help you buddy! :D
Answer with explanation:
The given functions in x are
1. f(x)=4 x² + 9 x
2. h(x)= 2 x
3. g(x)=18 x
To check whether the function is increasing or not , there are two ways
1. The graph of function is sloping Upwards.
2. For, two real x number ,that is if , a ≥ b, then , f(a) ≥ f(b).
All the three given function in x, are increasing because ,for increasing , x , value of function increases.
For Integral numbers,
⇒Function 1
f(x)=4 x² + 9 x
f(1)=4×1²+9×1
=4 +9
=13
f(2)=4×2²+9×2
=4 × 4 +18
=16 +18
= 34
f(2) - f(1)=34 - 13
= 21
→→Function B
h(x)= 2 x
h'(x)=2
Rate of change of function is constant, which is equal to 2.
→→Function C
g(x)=18 x
g'(x)=18
Rate of change of function is constant, which is equal to 18.
≡⇒→Rate of change of function ,f(x) is maximum among three functions.That is, f(x)=4 x² + 9 x , has highest rate of increasing, for increasing value of, x.

[tex]7.8+0.5\ \textgreater \ 6.2[/tex]
This also satisfies the theorem.

How many pieces 3/7 of a foot each can I make out of 7/2 feet of rope?
Answers
Final answer:
To find out how many 3/7 foot pieces can be made from 7/2 feet of rope, divide the total rope length by the length of one piece, resulting in 8 whole pieces with a small amount left over.
Explanation:
The question asks how many pieces of rope, each measuring 3/7 of a foot, can be made from a total length of 7/2 feet. To find the answer, you need to divide the total length of the rope (7/2 feet) by the length of each piece (3/7 foot), which is a division problem involving fractions:
(7/2) ÷ (3/7) = (7/2) × (7/3) = 49/6.
This means you can cut the rope into 49/6 pieces. Since you can't have a fraction of a physical piece of rope, the practical answer is that you can make 8 whole pieces of rope, each 3/7 of a foot long, with a little bit of rope left over.
You can make 8 full pieces of rope that are each 3/7 of a foot long from 7/2 feet of rope, with a small leftover piece.
Explanation:The question asks how many pieces of rope measuring 3/7 of a foot each can be made from 7/2 feet of rope. To find this, we divide the total length of rope by the length of one piece:
Total length of rope: 7/2 feet
Piece length: 3/7 foot
We divide 7/2 by 3/7, which is the same as multiplying 7/2 by the reciprocal
of 3/7 (which is 7/3):
(7/2) * (7/3) = 49/6
This simplifies to 8 1/6, which means you can make 8 full pieces of rope that are each 3/7 of a foot long, with a small piece leftover.

Using this, we can get our answer.
1/2 (4 * 4 * 6) + 4^2
1/2 * 96 + 16
48 + 16
64
Thus the answer should be 64in. ^2
The surface area of the pyramid is 64 inch².
What is Surface area?A three-dimensional shape's surface area is the sum of all of its faces. To calculate the surface area of a shape, we add the areas of each face.
Here the pyramid has 4 triangles and one square.
Side of base square = 4 inch
Height of Triangle = 6 inch
Then, area of base
= side²
= 4²
= 16 inch²
and, Area of Triangle = 1/2 x base x height
= 1/2 x 4 x 6
= 12 inch²
So, the Surface Area of pyramid
SA = 1/2 (4 x t) + side²
= 12 x 4 + 16
= 48+ 16
= 64 inch²
