The number of tiles that will fit along the edge of the square mosaic is 28 tiles.
The concept used here is finding the square root of an area to determine the length of a side of a square and then using simple division to determine the number of tiles that will fit along the edge of the square. This involves using the formulas for finding the area of a square and the perimeter of a square.
To determine the number of 2 in x 2 in tiles that will fit along the edge of a square mosaic, you need to determine the length of one side of the square mosaic. You can do this by finding the square root of the total area:
sqrt(196) = 14
So one side of the square mosaic is 14 inches. The perimeter of the square is 4 * 14 = 56 inches.
Since each tile is 2 inches wide, the number of tiles that will fit along the edge of the square mosaic is 56 / 2 = 28 tiles.
Thus, the number of tiles that will fit along the edge of the square mosaic is 56 / 2 = 28 tiles.

A house has 12 rooms (10 bedroom and 2 living rooms). We want to paint 4 yellow, 5 red and 3 purple. We do not want the living rooms to be the same color. In how many ways this can be done?
Total number of ways to paint rooms is 19,740.
We can solve this problem using the combinatorics. First, we choose the color for the living rooms, which can be done in 3*2 = 6 ways (yellow, red, or purple). Then, we choose the colors for the remaining 10 rooms.
Case 1 : living room is yellow and red
Then remaining colors are 3 yellow, 4 red, 3 purple
number of ways to paint living room = 2
number of ways to pain bedroom = 10!/(3! 4! 3!)
So number of ways = 2 * 10!/(3! 4! 3!) = 8400
Case 2 : living room is yellow and purple
Then remaining colors are 3 yellow, 5 red, 2 purple
So number of ways = 2 * 10!/(3! 5! 2!) = 5040
Case 3 : living room is red and purple
Then remaining colors are 4 yellow, 4 red, 2 purple
So number of ways = 2 * 10!/(4! 4! 2!) = 6300
Total number of ways = 8400 + 5040 + 6300 = 19,740

let a be a 3x2 matrix. suppose we know that u=[2 -3] and v=[4 2] satisfy the equations au = a and av =b. find a solution to x .
The solution to x, when the equations au = a and av =b are satisfied, will be x = [0 0].
Given that u = [2 -3] and v = [4 2] satisfy the equations au = a and av = b, we need to find a solution to the equation ax = b.
Let's express the matrix an as a column vector of its columns: a = [a1 a2]. Now, we have the following equations:
a*u = a
[a1 a2] * [2 -3] = [a1 a2]
This yields two equations:
2a1 - 3a2 = a1
2a1 - 3a2 = a2
Simplifying these equations, we get:
a1 = 3a2 ...(1)
a2 = 2a1 ...(2)
Substituting equation (2) into equation (1), we have:
a1 = 3(2a1)
a1 = 6a1
Solving for a1, we find a1 = 0.
Substituting this value back into equation (2), we have:
a2 = 2(0)
a2 = 0
Therefore, a solution to x is x = [0 0].

is it possible for one of φ∧(ψ ∨θ) and (φ∧ψ)∨(φ∧θ) to be true and the other false?
By examining the truth table, we can determine the two expressions are equivalent and it is possible for one of them to be true and the other false.
Given two Boolean expressions, it is possible for one of them to be true and the other false if they are not equivalent. For example, consider the two expressions: φ ∧ (ψ ∨ θ) and (φ ∧ ψ) ∨ (φ ∧ θ).
It is possible to construct a truth table for these two expressions, which shows all possible combinations of truth values for φ, ψ, and θ, along with the corresponding truth values for the two expressions.
Boolean logic is a branch of mathematical logic that deals with binary operations (i.e., true or false values) and is often used in computer science. One of the basic operations in Boolean logic is the logical conjunction (denoted by ∧), which represents the and operator. For example, if φ and ψ are two propositions, then φ ∧ ψ is true if and only if both φ and ψ are true.

how do I find a probability?
Answer:not sure
Step-by-step explanation:
Answer:
See explanation and examples below.
Step-by-step explanation:
The probability that an event (desired outcome) will occur is the quotient of the number of ways the event can occur (desired outcomes) and the total number of possible outcomes.
For example, consider a die. A die is a 6-faced cube with numbers 1 through 6 on its faces.
The total number of possible outcomes is 6 since it can land with any face with numbers 1 through 6 facing up.
What is the probability if getting a 5?
Here the desired outcome is a 5. There is only one desired outcome since only 1 face has a 5. The total number of possible outcome is 6.
p(5) = 1/6
The probability of getting a 5 is 1/6.
Another example:
A spinner has 4 sections of equal size.
1 section is red.
1 section is blue.
1 section is green.
1 section is yellow.
What is the probability of landing on red?
Desired outcome: landing on red
Number of desired outcomes: 2
Total number of possible outcomes: 4
p(red) = 1/4
Using the same spinner, what is the probability of landing on yellow or green?
Landing on the green section or landing on the yellow section are both desired outcomes, so the number of desired outcomes is 2.
The total number of outcomes is 4.
p(yellow or green) = 2/4 = 1/2

The solutions that match the given differential equation are a)y=0 and b)y=2x.
The differential equation is a homogeneous linear differential equation with constant coefficients, which can be written in the form of y" + p(x)y' + q(x)y = 0. The general solution to this type of equation is y = c1e^(rx) + c2e^(rx) where r is the root of the characteristic equation r^2 + p(x)r + q(x) = 0.
In this case, the equation is of the form xy'' - y' = 0. By dividing both sides by x, we get y'' - (1/x)y' = 0, which is a homogeneous linear differential equation with constant coefficients. The characteristic equation is r^2 - (1/x)r = 0. The roots of this equation are r1 = 0 and r2 = 1/x.
Therefore, the general solution to this differential equation is y = c1 + c2x.
y=0 is a solution of the differential equation since it satisfies the equation when plugged in.
y=2x is also a solution of the differential equation since it also satisfies the equation when plugged in.
y=2x^2 and y=2 are not solutions of the differential equation because when plugged into the equation they don't satisfy it.

if you have flipped t tails, you need to flip t 1 consecutive heads to win the game. what is the probability to win the game?
The probability of flipping 1 head in a fair coin flip is 0.5. The probability of flipping t heads in a row is [tex]0.5^{t}[/tex]. To win the game, you need to flip t heads after flipping t tails, so the probability of winning the game is ([tex]0.5^{t}[/tex])².
The probability of flipping heads in a fair coin flip is 0.5, meaning that the chance of getting heads on any given flip is 50%. If you have flipped t tails and now need to flip t heads in a row to win the game, then the probability of flipping t heads in a row is [tex]0.5^{t}[/tex].
To win the game, you need to flip t heads after t tails, so the overall probability of winning the game is ([tex]0.5^{t}[/tex])², which is the probability of flipping t heads multiplied by the probability of flipping t tails. In other words, the chance of winning the game is the product of the individual probabilities of each coin flip outcome. The probability of winning the game decreases as the number of heads you need to flip in a row increases.
To simplify the answer, let's assume that you need to flip t=3 heads in a row to win the game after flipping t=3 tails
The probability of flipping one head is 0.5, so the probability of flipping 3 heads in a row is (0.5)³ = 0.125.
The probability of flipping one tail is also 0.5, so the probability of flipping 3 tails in a row is (0.5)³ = 0.125.
The probability of winning the game, which is flipping 3 heads after flipping 3 tails, is (0.125)² = 0.015625.
So, the probability of winning the game is approximately 0.016, or 1.56%.

Answer:
3.4 in²
Step-by-step explanation:
We can solve for the area of the blue portion of this figure by subtracting the area of the circle (the area that is NOT blue) from the area of the surrounding square.
First, we can solve for the area of the square using arithmetic.
In this problem, the side length is twice the radius ([tex]r[/tex]) of the circle (given as 2 in), since the circle is circumscribed inside the square, meaning that it touches the square at all 4 midpoints of its sides.
[tex]\textrm{side length} = 2r[/tex]
[tex]\textrm{side length} = 2(2 \, \textrm{in})[/tex]
[tex]\textrm{side length} = 4 \, \textrm{in}[/tex]
Now we can solve for the area of the square using the formula:
[tex]\textrm{Area}_\square = \textrm{side length}^2[/tex]
[tex]\textrm{Area}_\square = (4 \, \textrm{in})^2[/tex]
[tex]\textrm{Area}_\square = 16 \, \textrm{in}^2[/tex]
Next, we can solve for the area of the circle using the formula:
[tex]\textrm{Area}_\circ = \pi r^2[/tex]
Remember that the radius of the circle was given as 2 in.
[tex]\textrm{Area}_\circ = \pi (2 \, \textrm{in})^2[/tex]
[tex]\textrm{Area}_\circ = 4\pi \, \textrm{in}^2[/tex]
Finally, we can solve for the area of the blue portion of the figure by subtracting the area of the circle from the area of the square.
[tex]\textrm{Area}_{\textrm{blue}} = A_\square - A_\circ[/tex]
[tex]\textrm{Area}_{\textrm{blue}} = 16 \, \textrm{in}^2 - 4\pi \, \textrm{in}^2[/tex]
If we plug this into a calculator, we approximately get:
3.4 in²
