A drawer contains 4 red socks, 3 white socks, and 3 blue socks. Without looking, you select a sock at random, replace it, and select a second sock at random. What is the probability that the first sock is blue and the second sock is red?
Answer:
[tex]\texttt{Probability}=\frac{3}{25} [/tex]
Step-by-step explanation:
Probability is the ratio of number of favorable outcome to total number of outcomes.
Total number of socks = 4 + 3 + 3 = 10
Number of blue socks = 3
Number of red sock = 4
[tex]\texttt{Probability of selecting blue sock}=\frac{3}{10} \\ [/tex]
[tex]\texttt{Probability of selecting red sock}=\frac{4}{10} \\ [/tex]
For finding the combined probability we need to multiply both the values
[tex]\texttt{Probability that the first sock is blue and the second sock is red}=\frac{3}{10}\times \frac{4}{10}=\frac{12}{100}=\frac{3}{25} \\ [/tex]
[tex]\texttt{Probability}=\frac{3}{25} [/tex]

Find two positive consecutive odd integers such that the square of the larger integer is one less than twice the square of the small integer.
Answer:
smaller integer = 5
Larger integer = 7
Step-by-step explanation:
Let the first odd integer be x
Then the next consecutive integer will be x + 2
Now, The square of larger integer is 1 less than twice the square of the smaller integer.
As, x < x + 2
Smaller integer = x
Larger integer = x + 2
⇒ (x + 2)² + 1 = 2·x²
⇒ x² + 4 + 4x + 1 = 2x²
⇒ x² - 4x - 5 = 0
⇒ x² - 5x + x - 5 = 0
⇒ x(x - 5) + 1(x - 5) = 0
⇒ (x - 5)(x + 1) = 0
⇒ x = 5 or x = -1
But we need positive integer so x = -1 is rejected.
Hence, x = 5
So, smaller integer = 5
Larger integer = 7

A prop for the theater club’s play is constructed as a cone topped with a half-sphere. What is the volume of the prop? Round your answer to the nearest tenth of a cubic inch. Use 3.14 to approximate pi.
Answer: V = 2712.94 cubic inches.
Step-by-step explanation: The prop is formed with two objects: cone and half of a sphere. To calculate the volume, find the volume of the cone and the half-sphere and add them together.
Volume of Cone:
V₁ = [tex]\frac{1}{3}.B.h[/tex]
B is area of the base
h is height
Since the cone has its base as a circle, the volume will be:
V₁ = [tex]\frac{1}{3}[/tex].π.[tex]r^{2}[/tex].h
V₁ = [tex]\frac{1}{3}[/tex] . 3.14 . [tex]9^{2}[/tex] . 14
V₁ = 1186.9 cubic inches
Volume of Half-Sphere:
V₂ = [tex]\frac{2}{3}[/tex].π.[tex]r^{3}[/tex]
V₂ = [tex]\frac{2}{3}[/tex] . 3.14 . [tex]9^{3}[/tex]
V₂ = 1526.04 cubic inches
Total Volume:
V = V₁ + V₂
V = 1186.9 + 1526.04
V = 2712.94 cubic inches
The volume of the prop is V = 2712.94 cubic inches

Answer: [tex] fg(x)=4x^3+12x^2-5x-15[/tex]
Step-by-step explanation:
Given: [tex]f(x)=4x^2-5\text{ and } g(x)=x+3[/tex]
We know that for any function f(x) and g(x), the multiplication function (fg) (x) is given by :-
[tex]fg(x)=f(x)g(x)[/tex]
Now, for the given functions, we have
[tex]fg(x)=(4x^2-5)(x+3)\\\\\Rightarrow\ fg(x)=4x^2(x+3)-5(x+3)\\\\\Rightarrow\ fg(x)=4x^3+12x^2-5x-15[/tex]
For the function f(x) = (8-2x)2 ,find f-1 . Determine whether f-1 is a function.
A.
f-1(x) = ;f-1 is a function
B.
f -1 (x) = ; f-1 is not a function
C.
f-1(x) = ;f-1 is not a function
D.
f-1(x) = ; f-1 is a function
Its not A!,
f-1(x) = 8±√x/2; f-1 is not a function, is the answer
What is the length of each edge of a cube if its surface area is 486 square units?
81 units
18 units
9 units
3 units
Answer:
the correct answer is 18 i hope this helps you
The length of each edge of a cube with a total surface area of 486 square units is 9 units, obtained by dividing the total surface area by 6 to get the area of one face and then taking the square root.
To find the length of each edge of a cube when you have the total surface area, you need to understand that a cube has 6 faces that are all squares of the same size. Since the total surface area of the cube is given as 486 square units, we can find the area of one face by dividing the total surface area by 6. Once we have the area of one face, we can find the length of one edge by taking the square root of that area because the area of a square is equal to the length of one side squared (Area = side x side).
Let's calculate:
Total surface area of the cube = 486 square unitsArea of one face = 486 / 6 = 81 square unitsLength of one edge = [tex]\\(\sqrt{81})[/tex] = 9 unitsTherefore, the length of each edge of the cube is 9 units.
Which of the following are independent pairs of events? Check all that apply.
A.Flipping two coins and having one show a head and the other show a head
B.Being sneezed on and catching a cold
C.When rolling a pair of dice, getting a total of 6 and having one die show a 3
D.Rolling a 4 on one die and rolling a 2 on another die
E.Seeing clouds and winning the lottery,
The best answer for these question would be:
A. Flipping two coins and having one show a head and the other show a head
D. Rolling a 4 on one die and rolling a 2 on another die
E. Seeing clouds and winning the lottery
Independent events in math means that the first situation does not affect the other variable. It is generally the individual probability that will happen to the solution. Which means that you have to determine whether the first situation will be affected on the second events that will happen. While the dependent events, have the opposite effect.
What is the equation of a vertical line passing through (−5, −2)?
x = −5
y = −2
x = −7
y = −3
Answer:
x = -5
First option is correct.
Step-by-step explanation:
The vertical line is passing through the point (−5, −2).
The equation of a vertical line is in the form x = k
For vertical line, the x-coordinate of each point that lie on the line remains same. Only the y-coordinate is different
For the given point, the x-coordinate = -5
Hence, k = -5
Therefore, the equation of line is x = -5
First option is correct.

The square of nine less than a number is three less than the number. What is the number ?
The original problem is translated into a quadratic equation. By following the process of expanding, moving all terms to one side and solving the resulting equation yield the overall possible solutions x = 4 or x = 1.
Explanation:The question is asking to solve for a number based on a given condition. In this case, let's symbolize this unknown number with x. The problem can be written as an algebraic equation which is (x-9)^2 = x-3. You solve it first by expanding the equation, then move all terms to one side of the equation, to get a quadratic equation. Then, solve the quadratic equation to get the possible values of x. If you follow these steps, you will find that the possible solutions for this equation are x = 4 or x = 1.

Michelle works at a store that sells clothing accessories. The supply function for baseball caps is P=Q-6, where P is the price and Q is the quantity of baseball caps. If Michelle sells the baseball caps for $19 apiece, how many baseball caps will the store make?
A. 31 baseball caps
B. 6 baseball caps
C. 19 baseball caps
D. 25 baseball caps
Answer:
25
Step-by-step explanation:
Given : The supply function for baseball caps is P=Q-6, where P is the price and Q is the quantity of baseball caps.
To Find: If Michelle sells the baseball caps for $19 apiece, how many baseball caps will the store make?
Solution:
The supply function for baseball caps is P=Q-6
where P is the price
Q is the quantity of baseball caps.
Now we are given that Michelle sells the baseball caps for $19 a piece.
So, P = 19
Substitute the value in the function:
19=Q-6
19+6=Q
25 =Q
Thus If Michelle sells the baseball caps for $19 apiece, the store make will make 25 baseball caps .
