Answer:
Y-6=-1/2(x-(-1) )
Step-by-step explanation:
The Equation for the point-slope of the line is y - 6 = -1/2(x + 1).
What is the slope of a line?A line's slope is defined as the ratio of the change in y coordinates to the change in x coordinates.
Both the net change in the y-coordinate and the net change in the x-coordinate are denoted by y and x, respectively.
Given coordinates (-1,6) and (1,5).
the slope of line is given by,
m = (y₂- y₁)/(x₂ - x₁)
y₂- y₁ = 5 - 6 = -1
x₂ - x₁ = 1 - (-1) = 2
m = -1/2
to find the equation at y = 6
when y = 6, x = -1
the equation is given by
y - y₁ = m(x - x₁)
y - 6 = -1/2(x -(-1))
y - 6 = -1/2(x + 1)
Hence equation of a line is y - 6 = -1/2(x + 1).

The fictitious state of Aribraska has a graduated state income tax.
Residents pay 3% on the first $15,000 of income.
The next $25,000 earned is taxed at a rate of 5%.
Any money earned above $40,000 is taxed at 7%.
The income tax for Aribraska is modeled by a piecewise defined function.
Over which part of the domain is the piecewise function defined as
f(x) = 0.05x – 300?
An Aribraska resident who earns $32,000 would owe how much in tases?
$1,300
$1,600
$1,740
Answer:
$1300
Step-by-step explanation:
The piecewise function is defined as f(x) = 0.05x - 300 over the income range of $15,000 to $40,000. An Aribraska resident who earns $32,000 would owe $1,600 in taxes.
Explanation:The piecewise function is defined as f(x) = 0.05x - 300 over the part of the domain where the income is between $15,000 and $40,000. This is because the tax rate of 5% is being applied to the income in this range. For any income above $40,000, the tax rate is 7%, so the function would not be equal to 0.05x - 300.
To calculate the amount of taxes owed by an Aribraska resident who earns $32,000, we need to determine the income range that applies to this amount. Since $32,000 is within the range of $15,000 to $40,000, we can use the piecewise function to calculate the taxes:
f(32,000) = 0.05(32,000) - 300 = 1,600
Therefore, an Aribraska resident who earns $32,000 would owe $1,600 in taxes.

The probability that a certain state will be hit by a major tornado (category F4 or F5) in any single year is 1/18. Use this information to answer the questions below
(A) What is the probability that the state will be hit by a major tornado two years in a row?
Answer:
The probability that the state will be hit by a major tornado two years in a row is 0.00309.
Step-by-step explanation:
Independent events are those events that are not affected by the occurrence (or no occurrence) of other events. These events do not affect the probability of another even taking place.
For example, the events of winning a lottery and being late for work are independent or the events of taking a cab home and making dinner are also independent.
In this case we are provided that the probability that a certain state will be hit by a major tornado is, [tex]\frac{1}{18}[/tex].
Consider the event that a state was hit by the major tornado.
The event of the major tornado hitting a state a second time next year is not dependent on the fact that it had already hit that state last year.
The two events are independent.
Compute the probability that the state will be hit by a major tornado two years in a row as follows:
P (Tornado hits twice) = P (Tornado in 1st year) × P (Tornado in 2nd year)
[tex]=\frac{1}{18}\times \frac{1}{18}\\=0.00309[/tex]
Thus, the probability that the state will be hit by a major tornado two years in a row is 0.00309.
The probability that a state will be hit by a major tornado two years in a row, given that the probability for any single year is 1/18, is 1 in 324.
Explanation:The question is asking about the probability that a certain state will be hit by a major tornado two years in a row, given that the probability for any single year is 1/18. In this question, the two events are independent, meaning that the occurrence of a tornado in one year does not affect the occurrence of a tornado in the next year. Therefore, we can simply multiply the probabilities for each year to find the two-year probability.
To calculate, we take the probability of a tornado in one year (1/18) and multiply it by the same probability for the next year (which is also 1/18).
So, the calculation is (1/18) * (1/18) = 1/324.
This means that the probability that the state will be hit by a major tornado two years in a row is 1 in 324.

2x + 3
Step-by-step explanation:
Given
2x² + 5x + 3
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term
product = 2 × 3 = 6 and sum = 2 + 3 = 5
The factors are 2 and 3
Use these factors to split the x- term
2x² + 2x + 3x + 3 ( factor the first/second and third/fourth terms )
= 2x(x + 1) + 3(x + 1) ← factor out (x + 1) from each term
= (x + 1)(2x + 3) ← in factored form
Thus the other factor is (2x + 3)

The probability of rolling a sum of 4 or less with two dice is 6 out of 36 outcomes, which simplifies to 1/6 or 0.1667 when rounded to four decimal places.
Explanation:To calculate the probability that the sum of two rolled dice will be 4 or less, we can list all possible outcomes (the sample space) and then count the favorable outcomes. A single six-sided die has 6 faces, so the total number of outcomes when rolling two dice is 6 × 6 = 36. The pairs of dice that sum to 4 or less are: (1,1), (1,2), (1,3), (2,1), (2,2), and (3,1). There are 6 such pairs, so the probability of rolling a sum of 4 or less is 6/36, which simplifies to 1/6.
The probability should be rounded to four decimal places if necessary, but in this case, the fraction simplifies exactly to 1/6. Therefore, the probability is 0.1667 when rounded to four decimal places.

How many revolutions is 900 degrees
9 revolutions
3 revolutions
2.5 revolutions
4.5 revolutions
Answer: 2.5
Step-by-step explanation:
One complete revolution equals 360 degrees. To find out how many revolutions 900 degrees represent, you divide 900 by 360 resulting in 2.5 revolutions.
Explanation:To ascertain the number of revolutions in 900 degrees, consider that a full circle encompasses 360 degrees. Dividing 900 by 360 yields 2.5, revealing that 900 degrees translates to 2.5 revolutions. This calculation stems from the fundamental concept that each complete revolution covers 360 degrees. In essence, the formula involves dividing the given degree measure by the standard degree value for a full revolution. Consequently, this approach facilitates the conversion of angular measurements into a more comprehensible representation of revolutions, aiding in the interpretation of rotational or circular motions within mathematical or physical contexts.
