Consider the equation 82 + 4y = 64. Where does the graph intersect the y-axis? Fill in the coordinate point:( Question 3
Answers
The value of the equation for which the graph intersect the y-axis is -9/4.
The given equation is 82 +4y = 64
We need to calculate the coordinate where the graph intersect the y-axis.
So, 82 +4y = 64
Subtracting 82 from both sides, we have
82 +4y - 82 = 64 - 82
4y = -18
Now, Dividing the equation by 4, we get :
y = -18/4
So, y = -9/4
Hence, the value of the equation for which the graph intersect the y-axis is -9/4.

The slope of the line segments that form my two sides is 0.75, and the length of each side is 5 units. What are my other two vertices?
Answers
According to the information, the vertex at the top left of the parallelogram is (4, 8.25). Thus, the other two vertices of the parallelogram are (2, 5), (9, 5), (7, 8), and (4, 8.25).
How to find the vertices of the parallelogram?To find the vertex of the parallelogram we can use the point-slope form of a line: y - y1 = m(x - x1), where,
m = slope(x1, y1) = point on the lineFor the side sloping up from left to right, we can use the point (2, 5), since it is on the bottom side of the parallelogram. Plugging in the values, we get:
y - 5 = 0.75(x - 2)Simplifying, we get:
y = 0.75x + 3.5To find the point where this line intersects the top side of the parallelogram, we can use the fact that the length of the sloping side is 5 units. We know that the endpoint of the bottom side at (2, 5) is 5 units away from the intersection point in the x-direction, so we can add 5 to the x-coordinate to find the intersection point. Plugging in x = 7 into the equation above, we get:
y = 0.75(7) + 3.5 = 8Therefore, the vertex at the top right of the parallelogram is (7, 8).
For the side sloping down from left to right, we can use the point (9, 5), since it is on the bottom side of the parallelogram. Plugging in the values, we get:
y - 5 = -0.75(x - 9)Simplifying, we get:
y = -0.75x + 11.25To find the point where this line intersects the top side of the parallelogram, we can again use the fact that the length of the sloping side is 5 units. We know that the endpoint of the bottom side at (9, 5) is 5 units away from the intersection point in the x-direction, so we can subtract 5 from the x-coordinate to find the intersection point. Plugging in x = 4 into the equation above, we get:

the respone times for a certain ambulance company are normally distributed with a mean of 13 minutes.95% of the response times are between 10 and 16 minutes
Answers
The standard deviation of the response time is 1.53 minutes.
What is the standard deviation of the response time?To get standard deviation, we will determine z-scores corresponding to the given percentiles and use them to calculate the standard deviation.
Z-score = z = (x - μ) / σ
For the lower bound of 10 minutes:
z = (10 - 13) / σ
For the upper bound of 16 minutes:
z = (16 - 13) / σ
As normal distribution is symmetric, the z-score corresponding to the lower tail of 2.5% is -1.96, and the z-score corresponding to the upper tail of 2.5% is 1.96.
Using z-scores, we set up equations:
(10 - 13) / σ = -1.96
(16 - 13) / σ = 1.96
Solving the first equation:
-3 / σ = -1.96
σ = -3 / -1.96
Solving the second equation:
3 / σ = 1.96
σ = 3 / 1.96
Dividing both sides by 1.96:
-3 / 1.96 = σ
1.53 = σ

2y - 3x = 0
Answers
The two variable equations when solved for x in terms of y is given as the equation y = 3x/2, and option A is the correct answer.
What are equations?A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("="). For illustration, 2x - 5 = 13. Two expressions are combined in an equation using an equal symbol ("="). The "left-hand side" and "right-hand side" of the equation are the two expressions on either side of the equals sign. Typically, we consider an equation's right side to be zero.
The given equation is:
2y - 3x = 0
Add 3x on both sides of the equation:
2y -3x + 3x = 3x
2y = 3x
Divide both sides of the equation with 2:
2y / 2 = 3x / 2
y = 3x/2
Hence, the two variable equations when solved for x in terms of y is given as y = 3x/2, and option A is the correct answer.

You pick a marble, roll a die, and pick a card. How many outcomes are possible?
Answers
The total number of possible outcomes is given by the expression 6n × 52, where n represents the number of marbles to choose from.
How to determine How many outcomes are possibleTo determine the number of possible outcomes, we need to consider the number of outcomes for each event and then multiply them together.
1. Picking a marble: Let's assume there are n marbles to choose from. If there are n marbles, then the number of outcomes for this event is n.
2. Rolling a die: A standard die has 6 sides numbered 1 to 6. Therefore, the number of outcomes for this event is 6.
3. Picking a card: A standard deck of cards has 52 cards. Hence, the number of outcomes for this event is 52.
To find the total number of possible outcomes, we multiply the number of outcomes for each event together:
Total number of outcomes = (number of outcomes for picking a marble) × (number of outcomes for rolling a die) × (number of outcomes for picking a card)
Total number of outcomes = n × 6 × 52
Therefore, the total number of possible outcomes is given by the expression 6n × 52, where n represents the number of marbles to choose from.

What is the area of the square that measures 3.1 m on each side
Answers
The area of the square with a side length of 3.1 meters is 9.61 square meters.
To find the area of a square, we need to multiply the length of one side by itself. In this case, the square has a side length of 3.1 m.
Area of a square = side length × side length
Substituting the given side length into the formula:
Area = 3.1 m × 3.1 m
To perform the calculation:
Area = 9.61 m²
It's worth noting that when calculating the area, we are working with squared units. In this case, the side length is in meters, so the area is expressed in square meters (m²). The area represents the amount of space enclosed within the square.
Remember, to find the area of any square, you simply need to multiply the length of one side by itself.

2) How many deer will live in this forest 25 years later? Round your answer to an integer.
3) After how many years, the deer population will be 301? Round your answer to an integer.
4) Use a calculator to answer this question: Many years in the future, about how many deer will live in this forest?
Answers
After about 21 years, the deer population will be 301. many years in the future, about 290 deer will live in the forest.
What is Algebraic expression ?
Algebraic expression can be defined as combination of variables and constants.
To find the number of deer living in the forest this year, we need to substitute x = 0 in the given equation:
P(0) = (1450(0) + 3870) ÷ (5(0) + 9)
P(0) = 3870 ÷ 9
P(0) = 430
Therefore, there are 430 deer in the forest this year.
To find the number of deer that will live in the forest 25 years later, we need to substitute x = 25 in the given equation:
P(25) = (1450(25) + 3870) ÷ (5(25) + 9)
P(25) = 54250 ÷ 134
P(25) ≈ 405
Therefore, there will be about 405 deer in the forest 25 years later.
To find after how many years the deer population will be 301, we need to solve the equation for x:
P(x) = 301
(1450x + 3870) ÷ (5x+9) = 301
1450x + 3870 = 301(5x+9)
1450x + 3870 = 1505x + 2709
55x = 1161
x ≈ 21.11
Therefore, after about 21 years, the deer population will be 301.
To find how many deer will live in the forest many years in the future, we can simply take the limit of the given equation as x approaches infinity:
lim(x→∞) P(x) = lim(x→∞) (1450x + 3870) ÷ (5x+9)
Using L'Hôpital's rule, we can take the derivative of the numerator and denominator separately:
lim(x→∞) P(x) = lim(x→∞) (1450) ÷ 5
lim(x→∞) P(x) = 290
Therefore, many years in the future, about 290 deer will live in the forest.

A coefficient is a quantity or number that is related to a variable. The variable is frequently followed by an integer that has been multiplied by the variable.
Define Coefficient.In mathematics, a coefficient is a quantity that is multiplied by a variable in a single term or in a polynomial's terms. Any sign that represents a constant value can be used, including numbers. It is often a number, however in other situations it could be a letter. In the formula: ax² + bx + c, for instance, x is the variable and a and b are the coefficients.
Therefore, a coefficient can be actual or hypothetical, expressed as a fraction or decimal, positive or negative, and real or imaginary. According to another definition, a coefficient is "Any number we multiply a variable by." For instance, the coefficient of the variable x in the expression 9.3x is 9.3, whereas the coefficient of the expression -5z is -5.
