10 Michael has a drawer with 8 pairs of black socks and 12 pairs of white socks. Without looking he takes a white pair of socks out of the drawer. What is the probability that the next pair he takes out is black?

Answers

Answer 1

The ration of white pair of socks and black pair of socks is 11:8 because Michael has already took one pair of the white socks so it's 11:8 between the two but to know the probability of one color you have to put it over the total amount of pair of socks so in total there are 19 now and 8 black pair of socks (were only looking for the probability of the black pair of socks and not the white)

8:19 is the ratio from black pair of socks to the total pairs of socks

You can also say 8/19 or 42% chance

Answer 2

Michael has already took white pair of socks, so that means that now in the drawer are left 11 pairs of white socks.

Therefore the propability of choosing a pair of black socks:
[tex]\frac{8}{19} [/tex]

A rational expression that will be undefined at x=1?

Answers

This rational. expression will be undefined when x=1. 3x+2÷(-x+1)

A rational expression of the form
[tex]r(x)= \dfrac{p(x)}{q(x)} [/tex]
will be undefined for the zeros of the expression [tex]q(x)[/tex]. For an expression with a zero equal to 1, the simplest way is to use [tex](x-1)[/tex] as a factor in [tex]q(x)[/tex]. In can be your only one, or you can mix in other factors.

But, so long as the denominator of [tex]r(x)[/tex] is equal to zero, as it is when [tex]q(x)=x-1[/tex], the expression will be undefined at that point x, because it would involve division by zero.

You could use as your sample:

You can try to get fancy and square some factors or add in some radicals or trigonometric functions or anything else, so long as the 1 makes the denominator equal to zero!

Four consecutive integer numbers add to 2. What are the numbers?

Let the smallest integer=x

The three consecutive integers will be x+1,x+2, x+3

Sum of four consecutive integers=2

So, x+x+1+x+2+x+3=2

Adding like terms, we get

4x+6=2

Subtract 6 from both sides

4x+6-6=2-6

4x+0=-4

4x=-4

To solve for x, let us divide by 4 on both sides

4/4x=-4/4

x=-1

So, the four consecutive integers are =x=-1

x+1=-1+1=0

x+2=-1+2=1

x+3=-1+3=2

So, the four consecutive integers are:= -1,0,1,2

If you take a certain number 2.5 times then add 1.75 and divide the result by 0.8, you’ll get 37.5. What was the original number?

Please show how you did it!

Answers

The answer is 11.3. You just take all the directions and you do the opposite operation.

Work

Step 1 - 37.5 x 0.8 = 30

Step 2 - 30 - 1.75 = 28.25

Step 3 - 28.25 divided by 2.5 = 11.3.

Step 4/ Final Answer - 11.3

lets take the certain number and call it 'x'
take 2.5 of the number = 2.5x
when we add 1.75 - 2.5x + 1.75
and divide by 0.8 - (2.5x+ 1.75)/0.8
the answer is 37.5
lets construct an equation with this information
(2.5x + 1.75)/0.8 = 37.5
2.5x + 1.75 = 37.5* 0.8
2.5x = 30 - 1.75
2.5x = 28.25
x = 28.25/2.5
x = 11.3

T₂ = 12 and T₁ =-6

∴Common ratio = 12/-6 = -2......

Multiply T₁ by -2 you'll have 12[T₂]

explain why the amount of propane in a grill’s tank and the time spent grilling could represent an inverse variation

Answers

The obvious answer is because propane is a gas at room temperature, while 2-propanol is a liquid at room temperature.

That happens because the intermolecular forces that exist between 2-propanol, or isopropyl alcohol, molecules are stronger than those that exist between propane molecules.

Final answer:

The amount of propane in a grill's tank and the time spent grilling represent an inverse variation. As the amount of propane in the tank decreases, the time spent grilling increases.

Explanation:

In the context of a propane grill, the amount of propane in the grill's tank and the time spent grilling represent an inverse variation. In an inverse variation, as one variable increases, the other variable decreases, and vice versa. In this case, as the amount of propane in the tank decreases (more grilling time), the time spent grilling increases. This is because the more propane that is used up, the less time you have left to grill before running out of gas.

The radius of the circular lens of a magnifying glass is 4 centimeters.
What is the area, in square centimeters of the glass?

Answers

Answer: 50.24 square centimeters.

Step-by-step explanation:

Given: The radius of the circular lens of a magnifying glass = 4 centimeters

The area of a circle is given by :-

[tex]\text{Area}=\pi r^2[/tex], where r is the radius of the circle.

Then the area of the circular lens of a magnifying glass is given by :-

[tex]\text{Area}=\pi (4)^2=(3.14)(16)=50.24\text{ square centimeters }[/tex]

Hence, the area of the circular lens of a magnifying glass = 50.24 square centimeters.

In a raffle, one ticket is randomly chosen from 80 tickets to receive free haircuts for a year. If Jake entered 6 tickets, what is the probability that he is not chosen to receive the free haircuts? Express your answer as a fraction in simplest form, percent, and decimal.

Answers

Final answer:

The probability that Jake is not chosen in the raffle is 37/40, 92.5%, or 0.925.

Explanation:

The question asks for the probability that Jake is not chosen to receive free haircuts for a year from a raffle of 80 tickets, where he entered 6 tickets.

First, we compute the probability that Jake is chosen, which is the number of tickets he entered divided by the total number of tickets, resulting in 6/80 or 3/40.

To find the probability that Jake is not chosen, we subtract this probability from 1 (the total probability space), yielding 1 - 3/40 = 37/40.

In the simplest form, this is already reduced. As a percent, this probability is 92.5%, and as a decimal, it is 0.925.

A student earned grades of C, A, B, and A in four different courses. Those courses had these corresponding numbers of credit hours: 4, 5, 1, and 5. The grading system assigns quality points to letter grades as follows: A = 4, B = 3, C = 2, D = 1, and F = 0. Compute the grade point average (GPA) and round the result to two decimal places.

Answers

Final answer:

To compute the GPA, multiply each grade by its corresponding credit hours, sum up the grade points, and divide by the total number of credit hours. In this case, the GPA is 3.40.

Explanation:

To compute the grade point average (GPA), we need to multiply each grade by its corresponding number of credit hours to get the grade points. Then, we sum up the grade points and divide by the total number of credit hours. Here are the calculations:

Course 1: C grade (2 grade points) x 4 credit hours = 8 grade pointsCourse 2: A grade (4 grade points) x 5 credit hours = 20 grade pointsCourse 3: B grade (3 grade points) x 1 credit hour = 3 grade pointsCourse 4: A grade (4 grade points) x 5 credit hours = 20 grade points

Total grade points = 8 + 20 + 3 + 20 = 51 grade points

Total credit hours = 4 + 5 + 1 + 5 = 15 credit hours

GPA = Total grade points / Total credit hours = 51 / 15 = 3.40

A Web site defines a regular polygon as “a polygon with all sides the same length.” Is this definition valid?

A. Yes, because all regular polygons fit this definition.
B. Yes, because a square is a regular polygon.
C. No, because some polygons that are irregular fit this definition.
D. No, because not all regular polygons fit this definition.

Answers

Final answer:

The definition of a regular polygon as a polygon with all sides the same length is incomplete because it does not include the requirement that all angles must also be equal. Therefore, the best answer choice is C, as some polygons with equal sides do not have equal angles and are not regular.

Explanation:

The definition of a regular polygon as “a polygon with all sides the same length” is not entirely accurate, because it overlooks an important aspect of regular polygons. For a polygon to be considered regular, it must not only have all sides of equal length but also all angles must be equal. Therefore, the correct answer is C. No, because some polygons that are irregular fit this definition. For example, an equilateral triangle and a square are both regular polygons because they satisfy both conditions. However, a rhombus may have all sides of equal length but can have angles that are not equal, which makes it an irregular polygon.

d. 7% to 10%

Answers

Answer:

The answer is b.

Step-by-step explanation:

Answer:

b. 3% to 5% is the right choice.

Step-by-step explanation:

When a person buys a house, he will pay anywhere between 2 to 5 percent of the actual home price or the purchase price in the closing fees.

For example - if a home costs $200,000, a person can pay between $4000 and $10000 in closing costs.

So, option B : 3% to 5% is the correct answer.
