Is the spinner below , what is the probability of lading on 2 ? Help me !!!!

Answer:

(Choice A)

Harry stains his shirt during the dinner.

Step-by-step explanation:

If Harry and Larry are having a barbecue dinner and the probability of Harry staining his shirt during the dinner is 1/5 and the probability of Larry staining his shirt during the dinner is 15%, Harry stains his shirt during the dinner is more likely.

Harry - 1/5 as a percent: 20%

Larry - 15% as a decimal: 0.15

Therefore 20% is more than 15 percent.

This makes the answer, Harry stains his shirt during the dinner.

Answer:

(TZ - 2P)/2 = S

Step-by-step explanation:

Multiply both sides by Z

T*Z = Z*2(S + P)/Z

TZ = 2*(S + P)                    Divide by 2

TZ/2 = 2(S + P)/2              Do the division

TZ/2 = S + P                      Subtract P from both sides

TZ/2 - P = S                       That's one answer. You could refine it.

Multiply P by 2 so that you can put TZ - 2P over a common denominator.

(TZ - 2P)/2 = S                   Is another answer.  

I think the second one is probably the best one.

Answer:

to find the vertical asymptote, you have to put the rational function in the simplest form, which means to cancel any common factor between the numerator and denominator. here we don't have anything to cancel. then take the denominator and equal it to 0. x-3=0 ,x=3

to find the horizontal asymptote, in this situation, the degree of the numerator and denominator are the same which is 1. therefore, y=the coefficient of the numerator ÷ the coefficient of the denominator. y=6÷1 ,y=6

Answer with explanation:

The given function is:

   [tex]f(x)=\frac{6x-2}{x-3}[/tex]

Horizontal Asymptote

   [tex]y= \lim_{x \to \infty} \frac{6x-2}{x-3}\\\\\text{Dividing Numerator and Denominator by ,x}\\\\\Rightarrow y=\lim_{x \to \infty} \frac{6-\frac{2}{x}}{1-\frac{3}{x}}\\\\\Rightarrow y=\frac{6-0}{1-0}\\\\\Rightarrow y=6[/tex]

Vertical Asymptote

→Substitute Denominator of f(x) =0

⇒x-3=0

⇒x=3

⇒x=3 is Vertical Asymptote , and y=6 is horizontal Asymptote.

5500% of 4600% is 2530

Order of Operations in Mathematics follow this following rule :

This rule is known as the PEMDAS method.

In working on a mathematical problem, we first calculate operation that is in parentheses, follow by exponentiation, then multiplication or division, and finally addition or subtraction.

Let us tackle the problem.

This problem is about Percentage.

Given:

What percent of 4600% is 2530?​

We can translate above questions into mathematical equation as follows:

[tex]x\% \times 4600 \% = 2530[/tex]

[tex]x\% \times \frac{4600}{100} = 2530[/tex]

[tex]x\% \times 46 = 2530[/tex]

[tex]x\% = 2530 \div 46[/tex]

[tex]x\% = \frac{55}{1}[/tex]

To convert above fraction , we could multiply with 100% :

[tex]x\% = \frac{55}{1} \times 100\%[/tex]

[tex]x\% = \boxed{ 5500 \% }[/tex]

Another Example:

50% of 4600 is 2300

80% of 4600 is 3680

100% of 4600 is 4600

120% of 4600 is 5520

Grade: Middle School

Subject: Mathematics

Chapter: Percentage

Keywords: Linear , Equations , 1 , Variable , Line , Gradient , Point , Multiplication , Division , Exponent , PEMDAS , percentange , percent

The 2530 is 55% of 46. This means that 2530 is 55% of 4600%, as 4600% is equivalent to 46 in decimal form.

To find what percent 2530 is of 4600%, we first need to understand that 4600% is equal to 46. Hence, we need to determine what percent of 46 is 2530.

Let x be the percentage we are trying to find. We can set up the equation:

x% of 46 = 2530

To solve for x, we divide both sides by 46:

x% = 2530 / 46

x% = 55

So, 2530 is 55% of 46.

To summarize, 2530 is 55% of 46. This means that 2530 is 55% of 4600%, as 4600% is equivalent to 46 in decimal form.

Answer:

(x + 4)(x + 2)

Step-by-step explanation:

Consider the factors of the constant term ( + 8) which sum to give the coefficient of the x- term ( + 6)

The factors are + 4 and + 2, since

+ 4 × + 2 = + 8 and + 4 + 2 = + 6, hence

x² + 6x + 8 = (x + 4)(x + 2) ← in factored form

The two binomials that are factors of this trinomial x^2+6x+8 would be (x + 4)(x + 2).

Factorization is expressing a mathematical quantity in terms of multiples of smaller units of similar quantities.

For an integer, factorization is the decomposition of that integer in terms of smaller integers which when multiplied with each other give back that considered number.

Those composing integers are called factors of that considered integers.

Consider the factors of the constant term ( + 8) which sum to give the coefficient of the x- term ( + 6)

x² + 6x + 8

The factors are - 4 and + 2, since

+ 4 × + 2 = + 8 and + 4 + 2 = + 6,

Answer: True

Step-by-step explanation: that is the correct definition on theoretical probability! :D

. Probability is calculated as the ratio of the number of favorable outcomes to the total number of possible outcomes, not unfavorable outcomesThe statement about theoretical probability in the question is false.

The provided statement about theoretical probability is false. According to the definition of theoretical probability, the probability of an event occurring is in fact the number of favorable outcomes divided by the total number of possible outcomes, not the unfavorable outcomes. To calculate the theoretical probability of an event A, one must count the number of outcomes that are favorable for event A (those that result in the event occurring) and divide by the total number of all possible outcomes.

Example:

If a die is rolled, the probability of rolling a three (a favorable outcome) is 1 in 6 (the total number of possible outcomes), as there is one three on a die and six possible outcomes in total.

Therefore, the correct way to express probability is:

Probability = (number of favorable outcomes) / (total number of possible outcomes)

Answer:

A large pizza costs $5 and a small pizza costs $3.

Let 'x' be the number of large pizzas and 'y' the number of small pizzas. We have that:

x + y = 150

5x + 3y = 570

Solving the system of equations:

x + y = 150 → 3x + 3y = 450 → 3y = 450 - 3x

5x + 3y = 570 → 5x + 450 - 3x = 570

2x = 120

x = 60

y = 150 - 60 = 90

Therefore. Carmen y Carlos will make 60 large pizzas and 90 small pizzas.

Answer:

9y +9x - 10a-10c -10b = 105

Step-by-step explanation:

Given

a+b+c = -6 and x+y = 5

We have to find 9y +9x - 10a-10c -10b

Rearranging the terms

9x+9y-10a-10b-10c

Simplifying will give us:

= 9 (x+y) - 10(a+b+c)

Putting the values of x+y and a+b+c

= 9(5) -10(-6)

=45+60

=105

Therefore,

9y +9x - 10a-10c -10b = 105 ..

Answer:

9y + 9x - 10a - 10c - 10b  = 105

Step-by-step explanation:

It is given that,  a+ b + c = - 6 and x + y = 5

To find the value of given expression

Let the expression be 9y +9x - 10a-10c -10b

9y +9x - 10a -10c -10b  = 9(y + x) - 10(a + c + b )

 = 9(x + y) - 10(a + b + c)

 = 9 * (5) - 10 * (-6)

 = 45 + 60

 = 105

Therefore 9y + 9x - 10a - 10c - 10b  = 105

3w + 6r ≤ 90

3(4) + 6(3) ≤ 90

12+18 ≤ 90

30 ≤ 90

So, Option 2 is incorrect.

3w + 6r ≤ 90

3(9) + 6(12) ≤ 90

27+72 ≤ 90

99 ≤ 90 (this equation doesn't hold because 99 is greater than 90 and not less than 90)

Option 3 is incorrect.

4) 12 hours walking; 10 hours running

w = 12 and r =120

3w + 6r ≥ 36

3(12) + 6(10) ≥ 36

36+60 ≥ 36

96 ≥ 36

3w + 6r ≤ 90

3(12) + 6(10) ≤ 90

Answer:

The distance formula d = rt, 'd' stands for distance, 'r' stands for rate and 't' stands for time.

It's a well known formula used in physics to solve problems that involves questions like "how fast", "how far", or "for how long".

In the formula d = rt, the variable t represents time. It's a consistent representation across situations whenever you are dealing with equations for motion, speed, or other physics contexts.

The variable t in the formula d = rt stands for time. This formula is used to calculate distance based on the rate of speed (r) and the time (t) traveled. To solve for time, you would rearrange the formula to t = d/r, which means time equals distance divided by rate.

In various physics and mathematical contexts, as shown in the reference information, the letter t consistently represents time. It could be the time an object takes to cover a certain distance at a given rate, or more complex scenarios involving non-Euclidean worlds or quantum mechanics. Nevertheless, whenever you see t in such equations, it is typically referring to time, unless otherwise specified.

Answer:

11 cartons

Step-by-step explanation:

Number of large boxes that can be contained in a carton = 8

Number of small boxes that can be contained in a carton = 10

Total number of boxes sent in one shipment = 96

This shipment contains both large and small boxes. Let there be x cartons of large boxes and y cartons of small boxes in one shipment. So, we can say,

Total number of large boxes in one shipment = Number of boxes in one carton * Total number of cartons = 8x

Similarly,

Total number of small boxes in one shipment = 10y

Since, total number of boxes in one shipment is 96, we can set up the equation as:

8x + 10y = 96

This equation can have following possible solutions:

We are given in the statement that are more large boxes than the small boxes, the valid solutions are:

Assuming that he sent both large and small boxes, the only valid solution will be:

This means, the merchant sent 7 cartons of large boxes i.e. 56 large boxes and 4 cartons of small boxes i.e. 40 small boxes. So in total he sent 11 cartons.

Answer:

Answer:

there are no extraneous solutions to the equation

Step-by-step explanation:

Given

[tex]\sqrt{8x+9}[/tex] = x + 2 ( square both sides )

8x + 9 = (x + 2)² ← expand

8x + 9 = x² + 4x + 4 ( subtract 8x + 9 from both sides )

0 = x² - 4x - 5 ← in standard form

0 = (x - 5)(x + 1) ← in factored form

Equate each factor to zero and solve for x

x - 5 = 0 ⇒ x = 5

x + 1 = 0 ⇒ x = - 1

As a check

Substitute these values into the equation and if both sides are equal then they are the solutions.

x = 5 : [tex]\sqrt{8(5)+9}[/tex] = [tex]\sqrt{49}[/tex] = 7

right side = 5 + 2 = 7

left side = right side ⇒ x = 5 is a solution

x = - 1 : [tex]\sqrt{8(-1)+9}[/tex] = [tex]\sqrt{1}[/tex] = 1

right side = - 1 + 2 = 1

left side = right side ⇒ x = - 1 is a solution

There are no extraneous solutions

Answer:

There are no extraneous solutions

Step-by-step explanation:

sqrt(8x+9) = x+2

Square each side

(sqrt(8x+9))^2 = (x+2)^2

8x+9 =  (x+2)^2

FOIL

8x+9 = x^2 +2x+2x+4

Combine like term

8x+9 = x^2 +4x+4

Subtract 8x from each side

8x-8x+9 = x^2 +4x-8x+4

9 = x^2 -4x+4

Subtract 9 from each side

0 = x^2 -4x-5

Factor

0=(x-5) (x+1)

Using the zero product property\

x-5 =0  x+1=0

x=5   x=-1

Check the solutions

x=5

sqrt(8*5+9) = 5+2

sqrt(40+9) = 5+2

sqrt(49) =7

x=-1

sqrt(8*(-1)+9) = -1+2

sqrt(-8+9) = -1+2

Answer:

c = sqrt( 29x^2 + 44x + 52)

Step-by-step explanation:

This is an application of the Pythagorean theorem

c = sqrt(a^2 + b^2)

a = 2x - 4

b = 5x + 6

c = sqrt( (2x - 4)^2 + (5x + 6)^2 )                           Substitute and expand

c = sqrt( 4x^2 -  16x + 16 + 25x^2 + 60x + 36)     Collect like terms

c = sqrt( 4x^2 + 25x^2 - 16x + 60x + 16+36)        Combine the like term pairs.

c = sqrt( 29x^2 + 44x + 52)

This does not factor into anything very nice.

Answer:

Madeline is standing 2x - 4 feet from the base of a tree, and the height of the tree is 5x + 6

Now we want to know the distance from Madeline's feet to the top of the tree.

You could picture it as a triangle rectangle, where the cathetus is the distance between Madeline and the tree and the distance between the floor and the top of the tree, in this case the distance between Madeline's feet and the top of the tree is the hypotenuse of such triangle rectangle, and can be obtained using the Pythagorean theorem: "the square of the hypotenuse is equal to the sum of the square cathetus"

then:

[tex]H^2 = (2x - 4)^2 + (5x + 6)^2[/tex]

[tex]H^2 = (4x^2 -16x + 16) + (25x^2  + 60x +36)[/tex]

[tex]H^2 = (29x^2 + 44x + 52)[/tex]

[tex]H = \sqrt{ (29x^2 + 44x + 52)}[/tex]

this is the distance from Madeline's feet to the top of the tree in terms of x.
