WHAT IS THE MEAN MEDIAN MODE?

The best estimate of the proportion of all women at this university who have a body temperature more than 2 standard deviations above the mean is 2.28%.

Since the sample is normally distributed and has a mean μ = 98.52 F and a standard deviation, σ = 0.727 F and we need to find the percentage of all womenat this university who have a body temperature more than 2 standards deviations above the mean.

Since the sample is normally distributed, 50% of the sample is below the mean. We have 34% of the sample at 1 standard deviation away from the mean and 47¹/₂% at 2 standard deviations above the mean.

So, the percentage below 2 standard deviations from the mean is 50% + 47¹/₂% = 97¹/₂%.

So, the percentage above 2 standard deviations from the mean is 100% - 97¹/₂% = 2¹/₂% = 2.5 %

Since 2.28 % is the closest to 2.5 % from the options, the best estimate is 2.28 %.

So, the best estimate of the proportion of all women at this university who have a body temperature more than 2 standard deviations above the mean is 2.28%.

After the rotation fo 180°, we will get the rectangle J'K'L'M', it can be seen in the image at the end of the answer.

A rotation of 180° always moves the figure 2 quadrants. In this case, the figure starts on the second quadrant, so after the rotation, the figure will be on the fourth quadrant.

Such that the point (x, y) will be transformed into (-x, -y).

Answer: Outdoor carpet should measure 30 square feet to cover the hole.

Step-by-step explanation:

Given:

Level 1 : Length = 5 ft ; Width = 2 ft

Level 2 : Length = 6 ft ; Width = 2 ft

Level 3 : Length = 4 ft ; Width = 2 ft

Area = L x W

Level 1 = 5 ft * 2 ft = 10 ft²

Level 2 = 6 ft * 2 ft = 12 ft²

Level 3 = 4 ft * 2 ft =   8 ft²

Total Area                30 ft²

Answer:

60°  and 180°

Step-by-step explanation:

Sum of interior angles of a polygon = (n - 2) × 180°

(where n is the number of sides)

A hexagon has 6 sides

⇒ Sum of interior angles of a hexagon = (6 - 2) × 180° = 720°

Let x = smallest unknown angle

Therefore, 3x = largest unknown angle

Sum the angles and solve for x:

⇒ 114° + 130° + 140° + 96° + x + 3x = 720°

⇒ 480° + 4x = 720°

⇒ 4x = 720° - 480°

⇒ 4x = 240°

⇒ x = 60°

Therefore, smallest unknown angle = 60°

and largest unknown angle = 3 × 60° = 180°

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the percentage be represented as A

Now , the value of A is given by the equation

A % of 33 = 25

So , substituting the values in the equation , we get

( A / 100 ) x 33 = 25

Multiply by 100 on both sides of the equation , we get

33A = 2500

Divide by 33 on both sides of the equation , we get

A = 2500/33

The value of A = 75.75 %

Therefore , the value of A is 75.75 %

Hence , the number 25 is 75.75 % of 33

Answer: No, Yes, Yes, No (in order)

Step-by-step explanation:

The area of a triangle is equal to the base*height/2.

The first choice:

Area = 6 ft * 5 ft/2

Area = 30 ft^2/2

Area = 15 ft^2

Therefore, this choice is not correct

The second choice:

Area = 12 ft * 5 ft/2

Area = 60 ft^2/2

Area = 30 ft^2

Therefore, this choice is correct

The third choice:

Area = 10 ft * 6 ft/2

Area = 60 ft^2/2

Area = 30 ft^2

Therefore, this choice is correct

The fourth choice:

Area = 20 ft * 6 ft/2

Area = 120 ft^2/2

Area = 60 ft^2

Therefore, this choice is not correct

We muss add the polynomic expression [tex]x^{2}+16\cdot x = -8[/tex]  by 64 on both sides.

In this question we must apply the completing the square method to solve a quadratic equation, which consists in apply algebra properties to reduce part of a expression into a square perfect trinomial.

According to the step 2, we have the following expression:

[tex]x^{2}+16\cdot x = -8[/tex]   (1)

By applying the principle of compatibility with addition and definition of addition, we have the following expression:

[tex]x^{2}+16\cdot x + 64 = - 8 + 64[/tex]

[tex]x^{2}+16\cdot x +64 = 56[/tex]

Now we proceed to solve the given expression:

[tex](x+8)^{2} = 56[/tex]

[tex]x+8 = \pm 2\sqrt{14}[/tex]

[tex]x = -8 \pm 2\sqrt{14}[/tex]

Answer:

x = 3, x = 1

Step-by-step explanation:

Okay, let's set the equation = 0:

3x^2 -12x + 9 = 0

Then, we factorise. To do this, we have to find 2 numbers which have a product of 9 and add up to -12. There are a few ways to do this, but a simple try and error is the easier when using numbers which don't have many factors. So here we know that to get a product of 9, there are only 2 options: 9*1 and 3*3. Now we have to figure out which of these add up to -12. But to do this, we have to take into account the 3, from the x^2 coefficient. This allows to know that the numbers will be 9*1. Then we just need to change the signs to make it work. This would give: -9*-1 (with 3*-1).

The fully factorised equation would be (3x-9)(x-1). Following this, you can always expand it quickly, to check that it really works correctly.

Now let's solve. (3x-9)(x-1) = 0

We say that when two numbers multiplied by each other equal to zero, one of them has to be zero. So if (3x - 9) was equal to 0:

3x - 9 = 0

3x = 9

x = 9/3

x = 3/1

x = 3

Now for the other:

x - 1 = 0

x = 1

Question:

[tex]\textsf{factor : \ } x^4+\dfrac{1}{x^2}[/tex]

Rewrite the expression using the exponent rule [tex]\dfrac{a^b}{a^c}=a^{(b-c)}[/tex]

[tex]\implies x^4+\dfrac{1}{x^2}=\dfrac{x^6}{x^2}+\dfrac{1}{x^2}[/tex]

Factor out common term [tex]\dfrac{1}{x^2}[/tex] :

[tex]\implies \dfrac{1}{x^2}(x^6+1)}[/tex]

Factor [tex](x^6+1)[/tex]:

Apply the exponent rule [tex](a^b)^c=a^{bc}[/tex] to get cubic exponents:

[tex]\implies x^6+1 = (x^2)^3+1^3[/tex]

Apply the sum of cubes formula: [tex]a^3+b^3=(a+b)(a^2-ab+b^2)[/tex]

where [tex]a=x^2[/tex] and [tex]b=1[/tex]:

[tex]\implies (x^2)^3+1^3=(x^2+1)((x^2)^2-x^2 \cdot 1+1^2)[/tex]

[tex]\implies (x^2+1)(x^4-x^2+1)[/tex]

Therefore,

[tex]\implies \dfrac{1}{x^2}(x^6+1)}=\dfrac{1}{x^2}(x^2+1)(x^4-x^2+1)[/tex]

Simplify by dividing the 2nd parentheses by [tex]x^2[/tex]:

[tex]\implies (x^2+1)\left(\dfrac{x^4-x^2+1}{x^2}\right)[/tex]

[tex]\implies (x^2+1)\left(x^2-1+\dfrac{1}{x^2}\right)[/tex]

Factor out [tex]x[/tex] from first parentheses:

[tex]\implies x\left(x+\dfrac{1}{x}\right)\left(x^2-1+\dfrac{1}{x^2}\right)[/tex]
