Answer:

PT = 24

Step-by-step explanation:

PT = TQ

3x + 6 = 5x - 6

12 = 2x

x = 6

PT = 3(6) + 6

PT = 18 + 6

PT = 24

Answer:

24

Step-by-step explanation:

From the pic,PT=TQ

therefore,

3x+6=5x-6

5x-3x=6+6

2x=12

therefore, x=12/2

                  =6

therefore, PT=3×6+6

                      =24

Answer:

[tex]cos\theta = -\frac{12}{37}[/tex]

Step-by-step explanation:

Given

[tex]tan\theta = \frac{35}{12}[/tex]

Quadrant: 3rd

Required

Determine [tex]cos\theta[/tex]

This question will be solved using the Pythagoras theorem

[tex]Hyp^2 = Adj^2 + Opp^2[/tex]

The tangent of an angle is calculated as thus;

[tex]tan\theta = \frac{Opp}{Adj}[/tex]

Comparing

[tex]tan\theta = \frac{35}{12}[/tex] to [tex]tan\theta = \frac{Opp}{Adj}[/tex]

We can conclude that

[tex]Opp = 35[/tex]    [tex]Adj = 12[/tex]

Substitute these values in the Pythagoras formula

[tex]Hyp^2 = 35^2 + 12^2[/tex]

[tex]Hyp^2 = 1225 + 144[/tex]

[tex]Hyp^2 = 1369[/tex]

Square root of both sides

[tex]Hyp = \sqrt{1369}[/tex]

[tex]Hyp = 37[/tex]

SInce [tex]\theta[/tex] is in the 3rd quadrant, then

[tex]cos\theta = -\frac{Adj}{Hyp}[/tex]

Where [tex]Adj = 12[/tex] and [tex]Hyp = 37[/tex]

[tex]cos\theta = -\frac{12}{37}[/tex]

Answer:

1

Step-by-step explanation:

The slope formula is [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex] so when you plug in all of the numbers to where they are supposed to be you would get [tex]\frac{1-3}{1-3}[/tex] which is [tex]\frac{-2}{-2}[/tex] which can be simplified to [tex]\frac{1}{1}[/tex] which is just 1 and that would be our answer

Answer:

Jeremy has 12 ways of painting his room.

He has 4 different wall colors and 3 different trim colors, so, if we want to know how many ways does he have to paint his room, we only need to multiply:

4 * 3 = 12

That's why he has 12 ways of painting his room. That's because for each of the 4 different wall colors, there are 3 trim colors he can use.

Answer: 12 different ways

Step-by-step explanation:

The question is asking for a combination of a wall color and a trim color because his room required one wall color and one trim color.

In this case, combination will be the number of first kind multiplies with the second kind. This is similar to sketching a tree diagram but instead, we will be using numerical method which will be quicker.

If you are still confused, I will provide some examples.

This also applies to your question. You have 4 different wall colors and 3 different trim colors.

4×3=12

You have 12 different ways to paint the room

Answer:

Supongo que en realidad dice

"... Para llegar de la planta baja hasta el piso 9..."

Ok, el elevador comienza en el piso 0, y llega hasta el piso 9 después de 5 movimientos.

De estos 5 movimientos, 3 suben (los podemos definir como positivos)

y 2 bajan (los escribimos como negativos).

Entonces, comienzo en 0.

0 + A + B + C - D - E = 9.

ahí dice que:

"desde el piso 0, tengo 3 subidas y dos bajadas de tal forma que el resultado final es el piso 9"

Una expresión algebraica matemática consta de variables y constantes junto con operaciones algebraicas. Al resolver problemas de palabras algebraicas, es necesario que los problemas se traduzcan con precisión en ecuaciones y se resuelvan correctamente.

m = -8/3

Answer:

y = 5x - 800

Step-by-step explanation:

If x represents the number of pages typed, 5x will represent how much money he earns from typing them, since he gets $5 per page.

Then, 800 needs to be subtracted from this because he spent $800 on the computer.

So, the equation will be y = 5x - 800 to represent his profit.

Answer:

Domain: [tex]\{x|x\in\mathbb{R}\}[/tex]

Range: [tex]\{y|y\in\mathbb{R},y\leq -2\}[/tex]

Step-by-step explanation:

The domain is the span of x-values the graph covers.

The range is the span of y-values the graph covers.

The given graph is a quadratic. We can see that the x-values will extend infinitely in both directions.

Thus, the domain is all real numbers.

In set notation, this is:

[tex]\{x|x\in\mathbb{R}\}[/tex]

From the graph, we can see that the maximum value is y=-2. The graph won't ever go above this.

So, the range is all real numbers less than or equal to -2.

In interval notation, this is:

[tex]\{y|y\in\mathbb{R},y\leq -2\}[/tex]

Step-by-step explanation:

So there are 4 chocolate chips and 12 oatmeal. In total, there are 16 cookies.

The probability of selecting a chocolate chip when you reach in for the first time will be 4/16 or 1/4.

The second time, you reach in, however, there would be one less chocolate chip cookie because you would've pulled one out previously. Thus, the probability is now 3/15 or 1/5.

So, the probability of pulling a chocolate chip cookie consecutively is:

Answer:

7560.

Step-by-step explanation:

There are 9 letters after the M consisting of  3 O's, 2 H's, 2 H's and 2 E's.

So the number of ways is   9! / (3!*2!*2!*2!)

= 362880 / (6*2*2*2)

= 362880 / 48

= 7560.

The number of ways the word MOSHOESHOE can be rearranged, if the letter M must always begin a word is 75,600 ways

Given:

MOSHOESHOE

n = total number of letters = 10

a = number of times O appears = 3

b = number of times S appears = 2

c = number of times E appears = 2

d = number of times H appears = 2

number of ways the word can be rearranged if M must always begin a word

= n! / (a! b! c! d!)

= 10! / (3!, 2!, 2!, 2!)

= (10 × 9 × 8 × 7 × 6 × 5 × 4× 3 × 2 × 1) / (3 × 2 × 1, 2 × 1, 2 × 1, 2 × 1)

= 3,628,800 / (6 × 2 × 2 × 2)

= 3,628,800 / 48

= 75,600 ways

Therefore, the number of ways the word can be rearranged if M must always begin a word is 75,600 ways

The complete question is:

Mr. Molesky observes a group of monkeys for 24 hours to learn about their behavior. He records how long they slept (in hours), how many bananas they ate, gender, age (in years), and the specific breed of monkey.

(a) What are the individuals in this data set?

(b) Identify the variables that were recorded, and indicate whether each one is categorical or quantitative?

Solution:

(a)

The term "individuals", in statistics, implies or denotes the objects or people included in a statistical study.

In this case it is provided that Mr. Molesky observes a group of monkeys for 24 hours to learn about their behavior.

So, the "individuals" in this data set are the monkeys.

(b)

Categorical variables belong to a certain category or label values. Such as gender of a person, state from which a person is from, color of the marble and so on.

Quantitative variables are those variables that assume numerical values and represent some sort of measurement. Such as height, weight, annual income of the people working at the same place and so on.

In this case the variables are:

Number of bananas the monkeys ate - Quantitative variable

Gender - Categorical variable

Age (in years) -  Quantitative variable

Specific breed of monkey - Categorical variable

The individuals in the data set refers to each monkey used in the experiment.

The variables in the experiment include :

Individuals used in a research refers to each species or subject used in the research finding.

DISCRETE variables involves variables whose values or numbers can be obtained by counting.while

y = 8+3x

filling in 25 for x, we find that:

Answer:

D.

Step-by-step explanation:

The domain remains the same [a, b) and the range  is [mc + n,md + n).

Step-by-step explanation:

I guess you mean 1cm:100000cm

Hence, for every 1 cm on the map 100000 cm is covered on the land.

Take the distance on the map for 20 km be x

Hence, 1:100000:: x: 2000000 cm

In order to solve this ratio, you must multiply the extremes and the moderates (nears).

Hence, 2000000×1=100000×x [1km=100000 cm]

Hence, 2000000= 100000x

Hence, x=2000000/100000 cm

Hence, x=20 cm

Hence, 20 cm on the map

Let x be a variable, and f(x) a function of that variable.

f(2) is a number ; it's the value of the function f(x) when x = 2, assuming that value exists.

f(x) = 2 is a statement ; it says there is some value of x for which the function returns a value of 2. Because it's a statement, it can be true or false.

Here's an example:

Define f(x) = sin(x). Then f(2) = sin(2) ≈ 0.909297.

If x is a real number, then the statement sin(x) = 2 is false, because -1 ≤ sin(x) ≤ 1 for all real x.

If we replace 2 with 1, on the other hand, we get

f(1) = sin(1) ≈ 0.84147

and

sin(x) = 1  ==>  x = π/2 + 2nπ

where n is any integer. (So we're talking about numbers like π/2, -3π/2, 5π/2, -7π/2, and so on.) We're saying here that any real number x of the above form satisfies the equation and makes the statement true.

Answer:

The correct answer is rational.

Step-by-step explanation:

The diameter of the tree belongs to the subset of rational numbers.

Natural numbers are the numbers 1, 2, 3 4, etc. Since 18.5 has a fractional/decimal component, it is not considered a natural number.  Whole numbers include all of the natural numbers, as well as 0; therefore, 18.5 is not a whole number either.

Integers include all whole numbers as well as negative numbers, but the integer category still does not encompass numbers with a decimal component.  For this reason, 18.5 is not an integer either.

Therefore, the only subset of numbers that 18.5 can fall under is rational numbers.  A rational number is a number that can be represented as a fraction.  18.5 can be represented as 37/2 and is thus a rational number.

You can also refer to the infographic given in the question for further clarity on which subsets of numbers are more inclusive than others.
