A class of 12 girls and 14 boys is going to choose 3 students to represent them in student government. Allie suggested that the first 3 students to arrive in class the next day should be the representatives. Bobby suggested that each student roll 2 numbers cubes and the 3 students with the highest sum should be the representatives. Whose method would result in a fair sample that represents the class population, and why?

Answers

Answer 1

The fairest method of these 2 suggested would be the one suggested by Bobby as it will be more random than the first three to show up to class.

Answer 2

Bobbys is fair because it is random. Allies is not fair cause some people can arrive early and it wont be fair for the people who can't.

A rectangle that is 21 inches long and 13 inches wide

Answers

To find the area you need to multiply length times width.

A= LxW
So what numbers would you multiply to get the answer?

The area of rectangular piece that is 21 inches long and 13 inches wide is 273 square inches

What is the Area of Rectangle?

The area of rectangle is -

A = L x B

Given is a rectangular piece that is 21 inches long and 13 inches wide

We can calculate the area using the formula -

Area = Length x Width

A = 21 x 13

A = 273 square inches

Hence, the area of rectangular piece that is 21 inches long and 13 inches wide is 273 square inches

The sum of 225 can be expressed as 200 + 25. Use the Distributive Property and GCF to rewrite the sum

Answers

To start, we have the expression 200+25 which represents the number 225. Now, to put this expression in distributive form, we're to find the greatest common factor (gcf) of 200 and 25 as according to the directions. This would be 25, since it is the largest factor of both 25 and 200. Then, we factor out 25 from both numbers and your answer should look like this: 25(8+1)

Mr. Rodriguez is packing bags of snacks for his children’s lunchboxes. If he has 20 blueberries and 30 grapes, what is the maximum number of bags of snacks that he can pack so that each bag has the same number of blueberries and grapes?

Answers

The common factor of 20 blueberries and 30 grapes is 5. So if you divide the blueberries and grapes you should get 4 blueberries and 6 grapes in each bag. In short, 5 bags.
If each bag has 4 blueberries and 6 grapes.

With equal distribution of blueberries and grapes, Mr. Rodriguez can pack maximum of 10 bags of snacks.

What is ratio?

Ratio is a quantitative relation between two amounts showing the number of times one value contains or is contained within the other.

Given is that Mr. Rodriguez is packing bags of snacks for his children’s lunchboxes and for that he has 20 blueberries and 30 grapes.

Now, we have -

Number of blueberries = n[b] = 20 blueberries

Number of grapes = n[g] = 30

For equal distribution, there should be a ratio of → n[b]/n[g] = 20/30 = 2/3

Or we can write it as 2 : 3. This means that in each box there should be 2 blueberries and 3 grapes.

The maximum number of bags [x] that Mr. Rodriguez can pack can be calculated as -

2x + 3x = 20 + 30

5x = 50

x = 10

Therefore, with equal distribution of blueberries and grapes, Mr. Rodriguez can pack 10 bags of snacks.

W = 3x + 7y solve for y

Answers

3x+7y=213x+7y=21Since 3x3x does not contain the variable to solve for, move it to the right side of the equation by subtracting 3x3x from both sides.7y=−3x+217y=-3x+21Divide each term by 77 and simplify.

To solve for y, we need to isolate it. Start by moving all of the values on the side the y is on that don't have y to the other side (kind of confusing the way I said it). By that, I mean subtract 3x from both sides:

W = 3x + 7y
W - 3x = 7y

Now, divide both sides by 7 to find the value of y:

W - 3x = 7y
(W - 3x)/7 = y

why is iron usually made into alloy for commercial uses?
A iron is too lightweight of a metal
B iron is a scare natural resource
C iron reacts easily with air and water
D iron by itself is to hard

answer fast please

Answers

Iron rusts as C states.
Answer is C.

Iron is typically alloyed for commercial uses because it reacts easily with air and water, leading to corrosion. By creating alloys such as steel with added elements like carbon and chromium, iron becomes more robust and rust-resistant, lending itself to a wider range of applications.

The reason iron is usually made into an alloy for commercial uses is that iron reacts easily with air and water, which is option C. Commercial alloys of iron, like steel, are produced by adding elements such as carbon and metals like manganese, chromium, nickel, tungsten, molybdenum, and vanadium. These elements create an alloy that is more resistant to corrosion (rusting), and they can be engineered to have different properties suitable for specific applications. For example, stainless steel contains chromium which helps in forming a protective oxide layer on the surface, thereby protecting the base iron from rusting.

While wrought iron, which is a commercially pure iron containing less than 0.2% carbon, is quite resistant to rust and is malleable and ductile, it has largely been replaced by mild steel. Mild steel, though not as corrosion-resistant as true wrought iron, is more cost-effective and widely available. Therefore, the commercial use of iron predominantly involves its transformation into alloys that benefit from enhanced strength, durability, and corrosion resistance.

What is the APR of a payday loan for $1460 due in 15 days that charges a $90 fee?

Answers

The answer I got is 150%
90/15= $6
6*365= $ 2191.5
2191.5 / 1460 * 100=150%

Answer:

The answer is 150%

Step-by-step explanation:

Amount of pay day loan = $1460

Also given is that the payday loan for $1460 due in 15 days that charges a $90 fee.

Per day it will charge = [tex]\frac{90}{15}=6[/tex] dollars

For a year it will charge = [tex]365\times6=2190[/tex]

Thus for the due amount of $1460, it will be charged on a rate of =

40 ÷ 160% = 40 ÷ (160 ÷ 100) = (100 × 40) ÷ 160 = 4,000 ÷ 160 = 25.
The answer is 25.

writing this in equation form you have 160% times X = 40

so 160% * x =40

160% as a decimal = 1.60

so 1.60 * x = 40

to find x divide both sides by 1.6

40 /1.6 = 25
