b = -2
As, y-intercept is -2.
Option B correct.
Find equation of the line.
y = mx+ b
y = -x + (-2)

solana purchased 50 boxes of ceramic pottery and 40 boxes of plates on Monday.On Thursday she purchased 58 boxes of ceramic pottery and 46 boxes of plates. the weekly total was 108 boxes of ceramic pottery and 96 boxes of plates. Let c represent the number of ceramic pottery pieces in each box, and let p represent the number of handpainted plates in each box.
Write two equivalent expressions to show the total number of ceramic pottery pieces and handpainted plates that Solana bought.
Both expressions are equivalent
What is the expression in mathematics?
In mathematics, an expression is a combination of numbers, variables, and mathematical operations that can be evaluated to a specific value or result. Expressions can be simple or complex, and they can be used to represent mathematical relationships or to perform calculations.
Let c represent the number of ceramic pottery pieces in each box, and let p represent the number of handpainted plates in each box.
To find the total number of ceramic pottery pieces that Solana bought, we can use the following expression:
c* (50 + 58) = c*108
This expression shows that the total number of ceramic pottery pieces is equal to the number of ceramic pottery pieces in each box multiplied by the total number of boxes of ceramic pottery that Solana bought.
Alternatively, we can use the following expression:
c50 + c58 = 108*c
This expression shows that the total number of ceramic pottery pieces is equal to the product of the number of ceramic pottery pieces in each box and the number of boxes Solana bought on Monday plus the product of the number of ceramic pottery pieces in each box and the number of boxes Solana bought on Thursday.
Similarly, to find the total number of handpainted plates that Solana bought, we can use the following expression:
p* (40 + 46) = p*86
This expression shows that the total number of handpainted plates is equal to the number of handpainted plates in each box multiplied by the total number of boxes of handpainted plates that Solana bought.
Alternatively, we can use the following expression:
p40 + p46 = 86*p
This expression shows that the total number of handpainted plates is equal to the product of the number of handpainted plates in each box and the number of boxes Solana bought on Monday plus the product of the number of handpainted plates in each box and the number of boxes Solana bought on Thursday.
Both expressions are equivalent, as they provide the same value for the total number of ceramic pottery pieces and handpainted plates that Solana bought.

What does a correlation of r =- 0.89 indicate?
The magnitude of the correlation coefficient indicates the strength of the association. For example, a correlation of r = 0.9 suggests a strong, positive association between two variables, whereas a correlation of r = -0.2 suggest a weak, negative association.
How to interpret a correlation coefficient?
The statistical measure of how well changes in the value of one variable predict changes in the value of another is called a correlation coefficient. The value rises or falls together when the variables are positively linked.
Is r or r 2 the correlation coefficient?
The summary table in the Regression output contains the "R" value, which is the coefficient of correlation. The term "coefficient of determination" also applies to R square. To obtain the value of R squared, multiply R by R. In other words, the square of the coefficient of correlation is the coefficient of determination.

During the tour, he was told that he would travel 10 miles upstream and then 10 miles downstream. He also knows that the river was flowing at a rate of 3 miles/hour and that the tour took about three hours.
The boat moved at a constant speed for the whole journey, although its actual speed varied with the current.

If it is negative b < 0, the function is undefined for -1 < x < 1.
If in an exponential function the base is less than zero, then it would make the function values complex for certain fractional values.

The second formula is the Completing the Square formula, which is used to solve any quadratic equation of the form ax² + bx + c = 0. This formula is used to rewrite the equation in the form (x + h)² = p , and then solve for the value of x. The third formula is the Factorization Method, which is used to solve any quadratic equation of the form ax² + bx + c = 0. This method is used to factor the equation into two linear factors, and then use either the Quadratic Formula or the Completing the Square formula to find the two values of x that are the solutions to the equation.

Note that the explicit equation and domain for an arithmetic sequence with a first term of 3 and a second term of 5 is n = 3 + 2(n − 1); all integers where n ≥ 1 (Option D)
What is an arithmetic sequence?Arithmetic progression or arithmetic sequence is a numerical series in which the difference between subsequent terms is constant. For example, the sequence 5, 7, 9, 11, 13, 15..
The first term of the arithmetic sequence is 3, followed by 5. Thus, the common difference is, 5-3 = 2. You use these values to the derived formulas for arithmetic progression. One of these formulas is
An = A1 + (n-1)d
where
An is the nth term in the sequence
A1 is the first term of the sequence
n is the total number of terms within the sequence
d is a common difference.
In this problem, A1 = 5 and d=2. Substituting to the equation,
An = 3 + (2)(n-1)
An = 3 + 2(n-1), where n should be more than 1. In order for it to become a sequence, it should contain more than one term.
Therefore, it is correct to appropriate an explicit equation and domain for an arithmetic sequence with a first term of 3 and a second term of 5 to be: n = 3 + 2(n − 1); all integers where n ≥ 1

Outcome Frequency
Heart 7
Spade 3
Club 6
Diamond 4
Determine the experimental probability of drawing a heart.
0.13
0.25
0.35
0.70
Answer:
For the first question, To determine the probability that a student studied for exactly 1 hour, we can use the formula:
P(X=1) = (number of students who studied for 1 hour) / (total number of students)
In this case,
P(X=1) = 8/30 = 0.27 (rounded to two decimal places)
So the probability that a student studied for exactly 1 hour is 0.27
For the second question, to determine the experimental probability of drawing a heart, we can use the formula:
P(Heart) = (number of times a heart is drawn) / (total number of draws)
In this case,
P(Heart) = 7/20 = 0.35
So the experimental probability of drawing a heart is 0.35
Therefore, the option 3 is the answer.

What is the principle of factorization Mcq?
Answer:
The principle of factorization is that every square matrix can be expressed as a product of a lower triangular matrix and upper triangular matrix. On the basis of this fact, these lower and upper triangular matrices help us in finding the unknowns.
