Answer:

Yes, it is a right triangle.

Step-by-step explanation:

Look at the points:

(1, 1), (1,4)

(1,4), (4,4)

(4,4), (1,1)

Find the slope between each point: In respective order, the first one is undefined, the second one has a slope of zero, and the third has a slope of 1. Because undefined slope is completely vertical (parallel to the y axis, and the slope of 0 is completely horizontal (parallel to the x axis), they are perpendicular (as it is transitive since the x axis is perpendicular to the y axis). Therefore, we know that anything that is perpendicular created a right angles', and thus, the any triangle with a right angle is a right triangle.

First we have to determine 30% of 12.

(30×12)÷100=3.6 so 3.6 is 30% of 12.

12 - 3.6= 8.4

Your answer is 8.4

Answer:

no horizontal asymptote

Step-by-step explanation:

When the degree of the numerator > degree of the denominator there is no horizontal asymptote but there is a slant asymptote.

Dividing the numerator by the denominator gives

[tex]\frac{x^2-x-6}{x+4}[/tex] = x - 5 + [tex]\frac{14}{x+4}[/tex]

There is a slant asymptote with equation y = x - 5

Answer:

D

Step-by-step explanation:

Arrange the data 2, 8, 18, 7, 42, 12, 16, 14, 11, 4, 1, 10, 19 in ascending order:

1, 2, 4, 7, 8, 10, 11, 12, 14, 16, 18, 19, 42

The number 42 is an outlier of the data.

1, 2, 4, 7, 8, 10, 11, 12, 14, 16, 18, 19, 42

Write a five-number summary:

Min:  1

Q1: 5.5 (the average between the middle terms of first half of the data)

Med: 11 (the  middle term of the data)

Q3: 17 (the average between the middle terms of second half of the data)

Max: 19

Outlier: 42

Only option D shows

Answer:

The last box plot

Step-by-step explanation:

A box plot is simply a graphical representation of the 5 number summary of a data set;

The minimum, first quartile, median, third quartile, and the maximum

in that order.

We can therefore arrange our given data set from the least to the greatest value;

1, 2, 4, 7, 8, 10, 11, 12, 14, 16, 18, 19, 42

The value 42 is an outlier since it is more extreme than the rest of the values.

From our arrangement of the data values above, we can note the following;

The minimum value is 1

The maximum value is 19

42 is an outlier, will be represented by a dark circle

The box-plot that matches the above is the last one and is thus the correct modified box-plot for the data

Answer:

19.2 grams

Step-by-step explanation:

We can solve the problem via ratio and proportions or simply through cross-multiplication;

we can formulate the following proportions;

(medication/weight) = constant

24/150 = x/120 = constant

where x is the quantity of medication for the 120 lb woman.

solving for x yields;

x = (24/150)*120

x = 19.2 g

Answer:

The correct answer is 19.2 grams

Step-by-step explanation:

It is given that, a 150lb woman receives 24 grams of medicine

To find the amount of medicine

150lb woman receives 24 grams

From the given information we can write,

1lb woman receives 24/150 grams

120lb woman receives = (24/150) * 120

 = 19.2 grams

Therefore 120lb woman get 19.2 grams

The correct answer is 19.2 grams

Answer:

[tex]\boxed{ a_{n} = 6a_{n-1}}[/tex]

Step-by-step explanation:

Step 1. Determine the common ratio

The formula for the nth term of a geometric sequence is

aₙ = a₁rⁿ⁻¹

Data:

a₁ = 4

n = 6

a₆ =31 104

Calculation:

31 104 = 4r⁵

r⁵ = 7776

[tex]r = \sqrt [5]{7776}[/tex]

r = 6

aₙ = 4(6)ⁿ

Step 2. Determine the recursive formula.

aₙ = 4(6)ⁿ

aₙ₋₁ = 4(6)ⁿ⁻¹

[tex]\dfrac{a_{n}}{{a_{n-1}}} = \dfrac{4(6)^{n} }{4(6)^{n-1}} = 6\\\\a_{n} = 6a_{n-1}[/tex]

Broker Q’s commission will be $13.56 less than Broker P’s

Step-by-step explanation:

Answer:

Broker Q will give Diana the better deal by $13.56.

Step-by-step explanation:

Diana wants to purchase a par value $1000 corporate bond. Broker P charges 4.4% of the market value, so the commission would be $46.06008 per bond. On the other hand, Broker Q would only charge $32.50 for each bond; due to this, the difference would be $13.56 in favor of Broker Q.

Answer:

P = 21%

Step-by-step explanation:

We look for the percentage of employees who are not more than 30 years old.

This is:

[tex]P = \frac{x}{n} *100\%[/tex]

Where x is the number of new employees who are not over 30 years old and n is the total number of new employees.

We do not know the value of x or n. However, the probability of randomly selecting an employee that is not more than 30 years old is equal to [tex]P = \frac{x}{n}[/tex]

Then we can solve this problem by looking for the probability that a new employee is not more than 30 years old.

This is:

[tex]P(X< 30)[/tex]

Then we find the z-score

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

We know that:

μ = 38 years

[tex]\sigma = 10[/tex] years

So

[tex]Z = -0.8[/tex]

Then

[tex]P (X<30) = P (\frac{X- \mu}{\sigma} < \frac{30-38}{10})\\\\P (X<30) = P(Z<-0.8)[/tex]

By symmetry of the distribution

[tex]P(Z<-0.8)=P(Z>0.8)[/tex]

Looking in the normal standard tables

[tex]P(Z>0.8)=0.211[/tex]

Finally P = 21%

Answer:

Width = 16 cm

Length = 9 cm

Step-by-step explanation:

Width = x cm

Length = x - 7

Area = 144 cm²

x(x - 7) = 144

x² - 7x = 144

x² - 7x - 144 = 0

(x - 16)(x + 9) = 0

x = 16 or x = -9 (rejected)

Width = 16 cm

Length = 16 - 7 = 9 cm

The width is determined to be 16 cm, and the length is 9 cm.

The student is asking for the dimensions of a rectangle given an area of 144 square centimeters and a length that is 7 centimeters less than its width. To find the dimensions, we can let the width be represented by w and the length by w - 7 (since the length is 7 centimeters less than the width). The area of a rectangle is calculated by multiplying the length by the width, which in this equation would be w(w - 7). We can set this equal to the given area of 144 square centimeters and solve for w.

Setting up the equation: w(w - 7) = 144. This simplifies to w^2 - 7w - 144 = 0.

To solve for w, we need to factor the quadratic equation, which results in (w - 16)(w + 9) = 0. The width can be 16 cm because it must be a positive value. Subsequently, the length is 16 - 7 = 9 cm.

Therefore, the dimensions of the rectangle are 16 cm in width and 9 cm in length.

Substitute

4x+2=x-4

Then solve

3x=-6

x=-2

Substitute answer into an equation to find y

y=-2-4

y=-6

So you solution is:

(-2,-6)

Answer:

bench:  $416; table:  $325.

Step-by-step explanation:

Let t and b represent the costs of the table and bench respectively.  Then:

t + b = $741, and t = b + $91.

Substituting b + $91 for t in the first equation, we get:

b + $91 + b = $741

Then 2b = $741 - $91, or 2b = $650

Then the bench costs $325 and the table ($325 + $91), or $416.

Answer:

C. are symmetrical

Step-by-step explanation:

Regular polygons mean that the polygon has sides with equal measures. This means that any line drawn from the vertex straight down passing through the center will create two symmetrical figures.  

A regular polygon is a polygon with n number of sides such that the measure of each side of the polygon is equal. The correct option is C.

A regular polygon is a polygon with n number of sides such that the measure of each side of the polygon is equal and the measure of the interior angle between any two consecutive sides is equal.

All regular polygons are symmetrical. This can be observed for any regular polygon with n number of sides.

Hence, All regular polygons are symmetrical.

The number of coins Julia found is 5

Step-by-step explanation:

We know that the total number of gold coins collected divided by the number of people collecting is 6. So we can set up an equation:

[tex]\frac{6+5+6+8+x}{5}=6[/tex]

this simplifies to:

[tex]\frac{25+x}{5}=6[/tex]

Using the multiplication property of equality and multiplying both sides by we get:

Answer:

{x,y} = {-2,2}

Step-by-step explanation:

Solve equation [2] for the variable  y  

  7y = 7x + 28

  y = x + 4

Plug this in for variable  y  in equation [1]

-8x + 4•(x +4) = 24

-4x = 8

Solve equation [1] for the variable  x  

4x = - 8  

x = - 2

By now we know this much :

   x = -2

   y = x+4

Use the  x  value to solve for  y  

   y = (-2)+4 = 2

Solution :

{x,y} = {-2,2}

and this intersects at only one point so your answer is A

The correct answer is: [tex]\[ \text{C. Infinitely many solutions} \][/tex].

To determine the number of solutions for the given system of equations, let's analyze it:

1. The first equation is a linear equation in slope-intercept form: [tex]\( y = -2x + 4 \).[/tex]

2. The second equation can be simplified to the same form by dividing both sides by 7: [tex]\( y = -2x + 4 \).[/tex]

Comparing the two equations, we can see that they represent the same line. In other words, the equations are equivalent.

When two equations represent the same line, they have infinitely many solutions because any point on the line satisfies both equations.

(4x−3)(3x²+2)

Step-by-step explanation:

Factor 12x3−9x2+8x−6

12x3−9x2+8x−6

=(4x−3)(3x2+2)

The factored form of the expression 12x³ - 9x² + 8x - 6 by grouping is (3x² + 2)(4x - 3).

To factor the expression 12x³ - 9x² + 8x - 6 by grouping, we can group the terms in pairs and factor out the common factors.

Step 1: Group the terms in pairs

(12x³ - 9x²) + (8x - 6)

Step 2: Factor out the greatest common factor from each pair

3x²(4x - 3) + 2(4x - 3)

Step 3: Notice that both terms now have a common factor of (4x - 3)

(3x² + 2)(4x - 3)

Therefore, the factored form of the expression 12x³ - 9x² + 8x - 6 by grouping is (3x² + 2)(4x - 3).
