Answer: Option D

D. 41​

Step-by-step explanation:

A value [tex]x_i[/tex] is considered an outlier if

[tex]x_i> Q_3 + 1.5IQR[/tex]

or

[tex]x_i <Q_1 - 1.5IQR[/tex]

Where

[tex]Q_3[/tex] is the third quartile

[tex]Q_1[/tex] is the first quartile

IQR is the interquartile range.

[tex]IQR = Q_3-Q_1[/tex]

In this case:

[tex]Q_3=92\\Q_1=72[/tex]

So

[tex]IQR = 92-72 =20[/tex]

[tex]Q_3 + 1.5IQR = 92 + 1.5*20 = 122[/tex]

[tex]Q_1 - 1.5IQR=72-1.5*20=42[/tex]

Then the outlier values will be all those greater than 122 or less than 42

Therefore the answer is the option D.

Answer:

720/1681

Step-by-step explanation:

First quadrant so everything is positive for a trig function of just the angle.  I would suggest just drawing a right triangle using tan(x)=40/9 (opp/adj). Find the hypotenuse which is sqrt(40^2+9^2)=sqrt(1600+81)=sqrt(1681)=41.  So sin(x)=40/41 and cos(x)=9/41.

Therefore sin(2x)=2sin(x)cos(x)=2(40/41)(9/41)=720/1681

Answer:

150(.40)^n is your equation

Step-by-step explanation:

Answer:

[tex]=150\cdot{0.4^n}[/tex]

Step-by-step explanation:

Let n be the number of rounds. Lets look at n=1 which is round one. Therefore if 40% of the contestants are eliminated then we can write an expression of the number of contestants eliminated:

[tex]=150\cdot{0.4}[/tex]

For round two, n=2:

[tex]=150\cdot{0.4)\cdot{0.4}=150\cdot{0.4^2}[/tex]

Therefore for the n number of rounds:

[tex]=150\cdot{0.4^n}[/tex]

Answer: 0.167 is the part of the hall that was not occupied. Or 16.7 %

Step-by-step explanation:

300-250=50 this is the number of seats not occupied since 250 is the amount occupied.

So, 50/300=5/30 which can be converted to a number which is 0.1666666667. It says to round to the thousandths place, which is the 3rd number. That is 0.167

Answer:

0.167 part of the hall was not occupied

Step-by-step explanation:

Given :In a concert hall, 250 seats out of 300 were occupied.

To Find :To the nearest thousand, what part of the hall was not occupied?

Solution:

Total seats = 300

Occupied seats = 250

Unoccupied seats = 300-250 = 50

So, The part of the hall was not occupied = [tex]\frac{\text{unoccupied seats}}{\text{total seats}}[/tex]

                                                                     = [tex]\frac{50}{300}[/tex]

                                                                     = [tex]0.167[/tex]

Hence 0.167 part of the hall was not occupied

Answer:

[tex]\frac{\sqrt[3]{100x}}{5}[/tex]

Step-by-step explanation:

we have

so

[tex]\sqrt[3]{\frac{4x*25}{5*25}}[/tex]

[tex]\sqrt[3]{\frac{100x}{125}}[/tex]

Remember that

[tex]\sqrt[3]{125}=5[/tex]

substitute

[tex]\sqrt[3]{\frac{100x}{125}}=\frac{\sqrt[3]{100x}}{\sqrt[3]{125}}=\frac{\sqrt[3]{100x}}{5}[/tex]

Answer:

{-5,-4,2}

Step-by-step explanation:

The domain is the inputs and the range is the outputs

The outputs are the y values

{ -5,2,-4,2}

We only list them once and in order from smallest to largest

{-5,-4,2}

[tex]125 = \frac{1}{125} {}^{y - 1} \\ 125 = ( {5}^{ - 2} ) {}^{y - 1} \\ \\ {5}^{3} = {5}^{2 - 2y} \\ 3 = 2 - 2y \\ - 0.5 = y[/tex]

Answer:

The answer is [tex]y=-0.5[/tex]

Step-by-step explanation:

In order to determine the "y" value, we have to change the way of we see the equation.

In these cases, when the variable is in the exponent and  it is possible to make two exponents in each side of the equation, we have to equal bases and then we have to make other equation between the exponents of both sides.

So,

[tex]125=(\frac{1}{25})^y^-^1\\(5)^3=(5^-^2)^y^-^1\\(5)^3=(5)^-^2^*^y^+^2\\[/tex]

Then, we have to make an equation between the exponents of both sides:

[tex]3=-2*y+2\\2*y=2-3\\2*y=-1\\y=\frac{-1}{2}=-0.5\\ y=-0.5[/tex]

Finally, the value of "y" is -0.5

Answer:

the answer will 100 percent be A

Answer:

The correct option is B.

Step-by-step explanation:

Let x is the  air conditioning unit's actual capacity and y is the maximum variance in British thermal units (Btu).

It is given that an air conditioning unit promises to have a cooling capacity of 6,000 British thermal units (Btu).

It means the maximum variance is less than or equal to absolute difference of actual capacity and 6,000.

[tex]y\leq |x-6000|[/tex]

The related equation of this inequality is a V-shaped curve with vertex (6000,0) and y-intercept (0,6000). Related curve is a solid curve because the points on curve included in the solution set.

The shaded region lie below the curve because the sign of inequality is ≤.

Therefore the correct option is B.

Answer:

There are no solutions to the inequality.

Step-by-step explanation:

|x - 3| < x – 3

1. Separate the inequality into two separate ones.

(1) x – 3 < x – 3

(2) x – 3 < -(x – 3)  

2. Solve each equation separately

(a) Equation (1)

[tex]\begin{array}{rcl}x - 3 & < & x - 3\\x & < & x\\\end{array}\\\text{This is impossible. No solutions exist.}[/tex]

(b) Equation (2)

[tex]\begin{array}{rcl}x - 3 & < & -(x - 3)\\x - 3 & < & -x + 3\\x & <& -x + 6\\2x & < & 6\\x & < & 3\\\end{array}\\\text{This is impossible. No solutions exist}[/tex]

For example, if x = 0, we get  

|0 - 3| < 0 - 3 or

3 < -3

Answer:

B. By simplifying 9 to [tex]3^{2}[/tex] to make both powers base three and subtracting the exponents

Step-by-step explanation:

When you have a division the quotient of powers property states that the exponents should be substracted, and by simplifying 9 to [tex]3^{2}[/tex] you end up with an equation like this:

[tex]\frac{3^{4} }{3^{2} }[/tex]=[tex]3^{2}[/tex]

Then you just have to substract the exponent from the denominator from the numerator´s exponent, which would be:

4-2=2

and the resultant equation would be:

[tex]3^{2} =3^{2}[/tex]

The Quotient of Powers Property allows you to subtract exponents when dividing expressions with the same base. The expression 3^4/9 simplifies to 3^2 because 9 can be expressed as 3^2, therefore their exponents are subtracted (4-2=2).

In this question, the Quotient of Powers Property is used. This property states that to divide where the base remains the same, you subtract the exponents. In the expression 3^4/9 = 3^2, we know that 9 can be expressed as 3^2.

Therefore, it becomes 3^4/3^2. According to the Quotient of Powers Property, we subtract the exponent of the denominator from the exponent of the numerator (4-2=2). Hence the expression simplifies to 3^2. The correct choice is B: By simplifying 9 to 3^2 to make both powers base three and subtracting the exponents.

Step-by-step explanation:

The zeros are the x-intercepts, when the curve passes through the x-axis.

I'm going to call our function P

P(x)=-0.5x^2+221x-224 is equal to 0 (our profit is equal to 0) when x (the unit price is such and such)

The answer is our unit prices when our profit is 0

The expression represents the monthly profit from sales of a product at a given unit price. The zero(s) of the expression represent the unit price(s) when the profit is equal to 0.

The expression -0.5x^2 + 221x - 224 represents the monthly profit, in thousands of dollars, from sales of a product when it is sold at a unit price of x dollars.

The zero(s) of the expression are the unit price(s) when the profit is equal to 0. To find the zero(s), we need to set the expression equal to 0 and solve for x.

Step-by-step explanation:

The 4 part of the ratio represents 30 red ribbons

Divide 30 by 4 to find the value of one part of the ratio

30 ÷ 4 = 7.5, hence

6 × 7.5 = 45 ← number of green ribbons

Final answer:

To park for $30 in a parking garage that charges $22.50 for the first hour and $2.50 for each additional hour, you can park for 4.2 hours.

Explanation:

The parking garage charges $22.50 for the first hour and $2.50 for each additional hour. Let's use 'x' to represent the number of hours. To find how many hours you can park for $30, we need to write and solve the equation.

Total cost equation:

$22.50 + $2.50(x-1) = $30
$22.50 + $2.50x - $2.50 = $30
$2.50x = $10.50
x = 4.2 hours

Therefore, you can park for 4.2 hours for $30 in the garage.

Final answer:

By repeating the perpendicular line segment construction twice using paper folding, one can effectively find the midpoint of a line segment, demonstrating the application of geometric principles and theorems related to perpendicular constructions.

Explanation:

If you repeat the perpendicular line segment construction twice using paper folding, you can construct the midpoint of a line segment. This is based on the principle that constructing perpendiculars at the ends of a given line segment and then erecting a third perpendicular midway between them will intercept the line segment at its midpoint. This is affirmed by the theorems that explain the geometrical properties and relationships of constructing perpendicular lines and their midpoints.

To elucidate, let's take a line segment AB of a certain length, and fold the paper to construct a perpendicular line at point A. Next, repeat the same action at point B. Now, fold the paper to find the midpoint of AB, and erect a perpendicular line at this midpoint. This results in the third perpendicular intersecting AB exactly at its midpoint, demonstrating that this method is effective for finding the midpoint of a line segment, thereby validating option A.

You can construct: The midpoint of a line segment.

The correct option is (A).

Paper folding constructions can be used to create geometric shapes and lines based on certain properties. Let's break down each of the given options and see if they can be achieved by repeating the perpendicular line segment construction twice:

A. The midpoint of a line segment: Yes, this can be achieved. Folding a line segment in half will give you its midpoint. By repeating the perpendicular line segment construction twice, you fold the line segment once to find a point equidistant from both endpoints (which is the midpoint), and folding it again should confirm that the resulting point is indeed the midpoint.

B. An angle congruent to a given angle: No, this cannot be achieved. The perpendicular line segment construction does not involve creating or manipulating angles, so it cannot be used to construct an angle congruent to a given angle.

C. A parallel to a line through a point not on the line: No, this cannot be achieved. The perpendicular line segment construction does not involve creating parallel lines.

D. An angle bisector: No, this cannot be achieved. Again, the perpendicular line segment construction does not involve manipulating angles, so it cannot be used to construct an angle bisector.

Therefore, the correct option is:

A. The midpoint of a line segment.

Answer:

Step-by-step explanation:

∠QRT and ∠SRT are supplementary angles,

therefore m∠QRT + m∠SRT = 180°.

(45x)° + m∠SRT = 180°            subtract (45x)° from both sides

m∠SRT = 180° - (45x)°

We know: the sum of the measures of the angles of the triangle is equal to 180 °. Therefore we have the equation:

(180 - 45x) + (57 + x) + 25x = 180         combine like terms

(-45x + x + 25x) + (180 + 57) = 180

-19x + 237 = 180             subtract 237 from both sides

-19x = -57             divide both sides by (-19)

x = 3
