Answer:
1. Red, 2. Green, 3. 1/2, 4. 3/10, 5. 4/5, 6. 1/2
Step-by-step explanation:
1. Red is the color with the least amount
2. Green is the color with the highest amount
3. 5 out of 10 of the marbles are green so that simplifies to 1/2
4. 3 out of 10 of the marbles are blue
5. 2 of the marbles are red so there are 8 left out of 10 and you have a 4/5 probability of getting something other than red
6. Half the marbles are green so you have a 1/2 probability to not get green

what are the solutions to the following system of equations?x y = 3y = x2 − 9 (3, 0) and (1, 2) (−3, 0) and (1, 2) (3, 0) and (−4, 7) (−3, 0) and (−4, 7)
Answers
Therefore, the solutions to the given system of equations are: (2√2, -5) and (-2√2, -5).
Hence, option D (3, 0) and (−4, 7) are not solutions of the system of equations.
The given system of equations is: xy = 3.............(1)y = x² - 9..........(2) We have to solve the system of equations.
The value of y is given in the first equation. Therefore, we will substitute the value of y from equation (1) into equation (2).xy = 3x(x² - 9) = 3x³ - 27x Now, we will substitute the value of x³ as a variable t.x³ = t
Therefore, t - 27x = 3t-24x=0t = 8x Substitute t = 8x into x³ = t.
We get:x³ = 8x => x² = 8 => x = ± √8 = ± 2√2. Substitute the value of x in y = x² - 9 to get the value of y corresponding to each value of x.y = (2√2)² - 9 = -5y = (-2√2)² - 9 = -5
A system of equations refers to a set of two or more equations that are to be solved simultaneously. The solution to a system of equations is a set of values for the variables that satisfies all the equations in the system.

Micaela is searching for the best spot to plant her tomato plants. The east side of her house gets 6 hours and 45 minutes of sunlight each day. The west side receives 7 hours and 15 minutes of sunlight on a daily basis. How much less sunlight does the east side receive?
Keep in mind that there are 60 minutes in 1 hour.
Answers
Answer:
420 + 15 = 435
360 + 45 = 405
435 - 405 = 30.
30 minutes less sunlight
Step-by-step explanation:
Answer:
The east side gets 30 minutes less sunlight.
Step-by-step explanation:
To find the answer we have to subtract 6 hours 45 minutes from 7 hours 15 minutes. As we see that 15 is less than 45, we turn 7 hours 15 minutes to 6 hours 75 minutes, and now we can subtract. 6 hours 75 minutes - 6 hours 45 minutes = 30 minutes. Now, we see that the answer is 30 minutes less sunlight.

(A) Row echelon form is :
\(\left[\begin{array}{ccc}1&3&0\\0&0&1\\0&0&0\end{array}\right]\)
(B)The reduced row echelon form is:
\(\left[\begin{array}{ccc}1&3&0\\0&0&1\\0&0&0\end{array}\right]\) × A
Row - Echelon matrix:
A row-echelon matrix means that Gaussian elimination is performed on the rows, and a column-echelon form means that Gaussian elimination is performed on the columns. That is, if the transpose of a matrix is in row form, then it is in column form. Therefore, in the rest of this article, only the row-echelon form is considered. Similar columnar properties can be easily derived by transposing all the matrices. Specifically, a matrix is in row-level form if below are all rows composed of all zeros.
Now,
Divide row 1 by -3 : R₁ = - R₁/3
\(\left[\begin{array}{ccc}1&3&-13/3\\-4&-12&17\\1&3&-4\end{array}\right]\)
Add row 1 multiplied by 4 to row 2:
R₂ = R₂ +4R₁:
\(\left[\begin{array}{ccc}1&3&-13/3\\0&0&-1/3\\1&3&-4\end{array}\right]\)
Add row 1 from row 3 : R₃ = R₃ -R₁
\(\left[\begin{array}{ccc}1&3&-13/3\\0&0&-1/3\\0&0&1/3\end{array}\right]\)
Since the element at row 2 and column 2(pivot element) equals 0, we need to swap the rows.
Find the first non-zero element in column 2 under the pivot entry.
As can be seen, there are no such entries. Move to the next column.
Multiply row 2 by -3: R₂ = -3R₂
\(\left[\begin{array}{ccc}1&3&-13/3\\0&0&1\\0&0&1/3\end{array}\right]\)
Add row 2 multiplied by 13/3 to row 1: R₁ = R₁ + 13R₂/3
\(\left[\begin{array}{ccc}1&3&0\\0&0&1\\0&0&1/3\end{array}\right]\)
Add row 2 multiplied by 1/3 from row 3 : R₃ = R₃- R₂/3

Devi’s mother is three times as old as Devi. Five years ago, Devi’s mother was four times as old as Devi was then. Find their present ages
Answers
Answer:
Devi's present age = 15 years
Devi's Mother's present age = 45 years
Step-by-step explanation:
Let the present age of Devi be x years.
Therefore, mother's present age = 3x
Five years ago:
Devi's age = (x - 5) years
Mother's age =( 3x - 5) years
According to the given condition:
Five years ago:
Devi's mother's age = 4 times Devi's age
3x - 5 = 4( x - 5)
3x - 5 = 4x - 20
20 - 5 = 4x - 3x
15 = x
x = 15 years
3x = 3* 15 = 45 years
Hence,
Devi's present age = 15 years
Devi's Mother's present age = 45 years

can you find the determinant of a non square matrix
Answers
No, the determinant of a matrix can only be calculated for square matrices. A square matrix has an equal number of rows and columns, while a non-square matrix has a different number of rows and columns.
The determinant is a mathematical property that is defined for square matrices only. It is a scalar value that represents certain characteristics of the matrix. To calculate the determinant of a square matrix, you can use various methods such as expansion by minors, cofactor expansion, or using the properties of determinants.
For example, let's consider a 3x2 non-square matrix:
```
A = [[1, 2],
[3, 4],
[5, 6]]
```
Since A is a non-square matrix, we cannot calculate its determinant.
the determinant is a concept applicable only to square matrices. Non-square matrices do not have a determinant.

Suggest regular languages L1 and L2 over {0,1} such that 1. L1⊈L2, 2. L2L1, and 3. (L1∪L2)∗=L1∗∪L2∗ (b) Prove or disprove whether condition 3 above holds for any regular languages, L1 and L2.
Answers
a). We have proved all the given conditions.
b). It is true that condition 3 holds for all regular languages L1 and L2.
(a) Regular languages L1 and L2 can be suggested as follows:
Let \(L_1={0^{(n+1)} | n\geq 0}\)
and
\(L_2={1^{(n+1)} | n\geq 0}\)
We have to prove three conditions:1. L1 ⊈ L2:
The given languages L1 and L2 both are regular but L1 does not contain any string that starts with 1.
Therefore, L1 and L2 are distinct.2. L2 L1:
The given languages L1 and L2 both are regular but L2 does not contain any string that starts with 0.
Therefore, L2 and L1 are distinct.3. (L1 ∪ L2)* = L1* ∪ L2*:
For proving this condition, we need to prove two things:
First, we need to prove that (L1 ∪ L2)* ⊆ L1* ∪ L2*.
It is clear that every string in L1* or L2* belongs to (L1 ∪ L2)*.
Thus, we have L1* ⊆ (L1 ∪ L2)* and L2* ⊆ (L1 ∪ L2)*.
Therefore, L1* ∪ L2* ⊆ (L1 ∪ L2)*.
Second, we need to prove that L1* ∪ L2* ⊆ (L1 ∪ L2)*.
Every string that belongs to L1* or L2* also belongs to (L1 ∪ L2)*.
Thus, we have L1* ∪ L2* ⊆ (L1 ∪ L2)*.
Therefore, (L1 ∪ L2)* = L1* ∪ L2*.
Therefore, we have proved all the given conditions.
(b)It is true that condition 3 holds for all regular languages L1 and L2.
This can be proved by using the fact that the union of regular languages is also a regular language and the Kleene star of a regular language is also a regular language.

Work out a formula connecting x and y.

Answers
The formula for y in terms of x when x and y are in direct proportion is y = x/4.
The formula connecting x and y when x and y are in inverse proportion is xy = 400.
When two variables x and y increase or decrease at the same pace, they are said to be in direct proportion. The ratio of x to y is hence constant.
Given that x = 40 and y = 10 when x and y are in direct proportion, we can write:
x/y = 40/10
Simplifying the ratio gives:
x/y = 4
To find a formula for y in terms of x, we can manipulate the above equation to isolate y:
x/y = 4
y/x = 1/4 (dividing both sides by x)
y = x/4
When two variables x and y have an inverse relationship, their product is said to be constant. So that xy = k, where k is a constant, y reduces as x grows and vice versa.
Given that x = 40 and y = 10 when x and y are in inverse proportion, we can write:
xy = k
Substituting the values of x and y gives:
40 × 10 = k
k = 400

Twenty-two years later, the price of a single share of stock has risen to over $110. One scatterplot shown summarizes the number of years since the initial stock offering in 1987 and the price of the stock, while the other compares years since 1987 to the log of stock price.
Based on these scatterplots, what type of model is most appropriate for summarizing the relationship between year and stock price?
A linear model is appropriate because the scatterplot of the transformed data is roughly linear.
An exponential model is appropriate because the scatterplot of time and log price is increasing.

What is linear model ?These scatterplots show that model type A is best suited to summarize the relationship between year and stock price. The scatterplot of the processed data is nearly linear, so a linear model is suitable.
A linear model is applicable if we can create a linear equation based on the connection between the independent and dependent variables (because there is no constant rate of change).
Otherwise, we can simulate the relationship using an exponential model.
An exponential model is:When the rate of increase representing the relationship between the year and stock price is proportional or constant, we utilize the exponential model.
By determining whether the ratio of the dependent values is the same, one can choose to describe the connection as an exponential equation.

Therefore , the solution of the given problem of ratio comes out to be 8:17 .
Describe ratio.The simple formula "a / b," where "b" may be greater than zero, can be used to determine a group of integers "a" and "b" that appear to be equal. Two ratios are combined to form a ratio. If there were only one man and three ladies, the fraction would be 1:1. In the group, there are 3/4 women and 1/4 males. Parts can be a division between things, a figure, or a particular percentage of a component's volume.
Here,
Let x be the price of plastic per square centimetre used to create visage A.
Consequently, the price of the components for aspect A is:
=> 4πx
The metal sector's size on face B is:
=> (20/360)π(2cm)² = (1/9)π cm²
The plastic sector's size on face B is:
=> (340/360)π(2cm)² = (17/9)π cm²
Face B's entire surface size is:
=> (1/9)π + (17/9)π = 2π cm²
Let y be the plastic's expense per square centimetre used to create face B.
Consequently, the price per cm2 of the metal used to create face B is three and a half times the price per cm2 of the plastic, leading to:
=> (3/2)y = (3/2)(2x) = 3x
The material cost for the metal section on face B is inversely correlated with its area, so:
=> (1/9)π(3x)
The price of the plastic used in the section on face B is inversely proportional to its area, so:
=> (17/9)πy
=> 8πx : 17πy = 8 : 17
