A researcher decides to determine if the type of writing utensil that a student uses while doing their math affects their accuracy. A group of 1200 high school students in Algebra are randomly divided into four groups. One group uses a regular pencil, another uses a mechanical pencil, one group uses a pen and the fourth group is allowed to use whatever type of utensil they feel like. A math test is given and the results are tabulated for accuracy. The variable- type of writing utensil - is what type of variable?

Answers

Answer 1

Since the variable type of writing utensil assumes labels and not numbers, it is classified as qualitative.

What are qualitative and quantitative variables?Qualitative variables: Assumes labels or ranks.Quantitative variables: Assume numerical values.

In this problem, the type of writing utensil has 4 labels: regular pencil, mechanical pencil, pen, whatever.

Hence, since the variable assumes labels and not numbers, it is classified as qualitative.

A right triangle has a hypotenuse with length 6 ft and a leg of length 3.4 ft.

What is the length of the other leg of the right triangle?

Enter the answer, rounded to the nearest hundredth.

Answers

Answer:

The answer is 4.94, rounded.

Step-by-step explanation:

The pythagorean theorem is : a^2+b^2=c^2

Inserting our numbers:

3.4^2+b^2=6^2

We can find 'B' by finding the other two numbers and subtracting 'A', from 'C'.

3.4*3.4= 11.56

6*6= 36

36-11.56= 24.44

Then, find the root of the difference

What are ratio and proportion?

A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.

Algebra is the study of graphic formulas, while logic is the interpretation among those signs.

A sum of money is divided between Laura and Joan in the ratio 2:3.

Laura’s share is $8.

Let J be the amount of Joan's share and L be the amount of Laura's share.

Then the amount of Joan's share will be

L / J = 2 / 3

8 / J = 2 / 3

By the cross multiplication, then the equation will be

2J = 8 x 3

2J = 24

 J = 24 / 2

 J = $12

The amount of the Joan's share will be $12.

Answer:

Its solving equations with variable on both sides

Step-by-step explanation:

Example: 8a = 3a+25

You have to make a variable on the both side

So.....

8a-3a = 3a+25-3a

And then solve it. So the last thing you will have is

5a = 25

If you want to the simplest form...divide 25 with 5

a = 25/5

a = 5

What are the pros and cons of using disposable plastic and paper products for dine-in fast food restaurants over reusable plates, cups, and silverware? atleast 2 pros and 2 cons

Answers

Answer:

Disposable items decompose after some time thus making them eco-freindly(safe for the environment) they also don't make a giant mess that takes thousands of years to decompose and even if they do it doesn't take that long for them to decompose on the other hand they are more expensive to mass produce than reusable items and they also are more expensive to buy than non Disposable but reusable items.

Non disposable but reusable Items when thrown away can take decades or even in some cases tens of thousands of years to decompose and can pose a threat to the environment they can be eaten by fish and other animals causing them in some cases to die they can cause a giant mess on the other hand they are cheap,and quick to make and you don't have to pay as much for dishes.

Solve completely \large x^4-4=x^3+2x

Answers

Move everything to one side and factorize by grouping.

x⁴ - 4 = x³ + 2x

x⁴ - x³ - 2x - 4 = 0

(x⁴ - 4) - (x³ + 2x) = 0

(x² - 2) (x² + 2) - x (x² + 2) = 0

(x² - x - 2) (x² + 2) = 0

(x - 2) (x + 1) (x² + 2) = 0

Then

x - 2 = 0   or   x + 1 = 0   or   x² + 2 = 0

x = 2   or   x = -1   or   x² = -2

If x is real, then the third case has no solution. Then x = 2 or x = -1. Otherwise, we can solve over the complexes and include x = ± √2 i where i = √(-1).

which is like a radical to ^3 to the square root of 54 after simplifying

Answers

Answer:

The radical that is equal to ∛54 is 3∛2.

Step-by-step explanation:

Given

∛54

We need to find the radical that is similar to ∛54, we need to break down the radicand 54, into smaller numbers, therefore, take the LCM of the number,

54 = 2 x 3 x 3 x 3

As we are taking the cube root, therefore, we need numbers that are repeating thrice.

Thus, the radical can be written as,

[tex]\sqrt[3]{54} =\sqrt[3]{2x 3x 3x 3} \\\\\sqrt[3]{54} =3\sqrt[3]{2}[/tex]

Hence, the radical that is equal to ∛54 is 3∛2

Answer:

[tex]3\sqrt[3]{2}[/tex]

Step-by-step explanation:

Original expression:

[tex]\implies \sqrt[3]{54}[/tex]

Factorize 54 using prime factorization:

[tex]\implies \sqrt[3]{2 \cdot 3^3}[/tex]

Apply radical rule: [tex]\sqrt[n]{ab} =\sqrt[n]{a} \cdot \sqrt[n]{b}[/tex]

[tex]\implies \sqrt[3]{2} \cdot \sqrt[3]{3^3}[/tex]

Apply radical rule: [tex]\sqrt[n]{a^n} =a[/tex]

[tex]\implies \sqrt[3]{2} \cdot 3[/tex]

[tex]\implies 3\sqrt[3]{2}[/tex]

Area of a triangle = 1/2 × base × height

Area of blue shape:

Area of rectangle + area of triangle

= (9 × 15) + (1/2 × (15 - 9) × 15)

Answer:

113.04

Step-by-step explanation:

The area of the square is 144 which means the length of each side of the square is 12. When the length on one side is 12 the radius of the circle will be half of the whole length. In this case, it means the radius is going to be 6. When we find the radius, we can use the formula r^2pie to find the area for the circle.

6 * 6 * 3.14

= 113.04

Answer:

Area = 113.04 in²

Step-by-step explanation:

Given:

Area of the square = 144 in²

Area of a square

[tex]\sf A=s^2\quad \textsf{(where s is the side length)}[/tex]

Substitute the given area of the square into the formula and solve for s:

[tex]\begin{aligned}\sf A & = \sf s^2\\\implies \sf 144 & = \sf s^2\\\sf \sqrt{144} & = \sf \sqrt{s^2}\\\sf 12 & = \sf s\\\implies \sf s & = \sf 12\:\:inches\end{aligned}[/tex]

From inspection of the given diagram, the side length of the square is equal to the diameter of the circle.  Therefore, the diameter is 12 inches.

Radius of a circle

[tex]\sf r = \dfrac{1}{2}\:d\quad \textsf{(where d is the diameter)}[/tex]

Substitute the found diameter into the formula and solve for r:

[tex]\begin{aligned}\sf r & = \sf \dfrac{1}{2}\:d\\\implies \sf r & = \sf \dfrac{1}{2}(12)\\\sf r & = \sf 6\:\:inches\end{aligned}[/tex]

Area of a circle

[tex]\sf A= \pi r^2 \quad \textsf{(where r is the radius)}[/tex]

Substitute the found radius into the formula and solve for A:

[tex]\begin{aligned}\sf A & = \sf \pi r^2\\\implies \sf A & = \sf 3.14 \cdot 6^2\\& = \sf 3.14 \cdot 36\\& = \sf 113.04\:\: in^2\end{aligned}[/tex]

Therefore, the approximate area of the paper circle is 113.04 in².

Answers

Answer:

411

Step-by-step explanation:

Because it has a 4 , 1 , and a 1

meaning the first number can't be 1 so it is automatically a 4.

and then the only 2 numbers left is 2 one's so you have to put them in their also automatically and 4 is asking 1 to round up can it.

411 can't round up,it would round down because 1 is 4 and below so it can't go up and goes down.

so 4 1 1 can't go up the number would have to be 450 to go to 500 but because it is 411 it goes down to 400 because it is rounded to 400.
