If average size of bass caught in strawberry lake is normally distributed, then the probability that the size of fish we caught is more than 15 inches is 0.3085.
The mean-size of the bass caught is (μ) = 13 inches,
The standard-deviation of the bass caught is (σ) = 4 inches,
we have to find probability that size of fish we caught is more than 15 inches.
We will use the z-score formula:
⇒ z = (x - μ)/σ,
So,
⇒ z = (15 - 13)/4 = 0.5,
Now, we need to find the probability of getting a z-score of 0.5 or higher. We use a standard normal distribution table to find this probability.
⇒ P(Z > 0.5) = 0.3085
Therefore, the required probability is 0.3085 or 30.85%.

A maze and walkway with the same total area of 5,616 square yards has a walkway that is one yard wide. What are the dimensions of this maze?
The total width of the maze is 51.5+2=53.5 yards and the total length of the maze is 105 yards.
What is an Equations?Equations are mathematical statements with two algebraic expressions on either side of an equals (=) sign. It illustrates the equality between the expressions written on the left and right sides. To determine the value of a variable representing an unknown quantity, equations can be solved. A statement is not an equation if there is no "equal to" symbol in it. It will be regarded as an expression.
The total area of the maze and walkway is equal to the area of the maze plus the area of the walkway. The area of the walkway is equal to the length of the maze plus twice its width since the walkway is one yard wide on both sides of the maze.
Let x be the width of the maze. So, (x+2) is the width of the maze and walkway, and (2x+2) is the length of the maze and walkway.
length×width=area
(2x+2)(x+2)=5616
2x²+6x+4=5616
2x²+6x=5612
Write in the form x2+bx=d by dividing both sides by 2:
x²+3x=2806
Complete the square by adding (23)2=2.25 to each side:
x²+3x+2.25=2806+2.25
(x+1.5)²=2808.25
Take the square root of both sides:
x+ 1.5 = ±√2808.25
x = −1.5±√2808.25
x ≈ −54.5 or x ≈ 51.5
A negative solution does not make sense so we take x≈51.5.
Hence, the total width of the maze is 51.5+2=53.5 yards and the total length of the maze is
2(51.5)+2
= 105 yards.

Solve the following quadratic equation for all values of x in simplest form
9(x^2 −10)−3= 7
Answer: To solve the quadratic equation, we can start by simplifying the left side of the equation:
9(x^2 −10)−3 = 7
9x^2 - 90 - 3 = 7
9x^2 - 93 = 7
Next, we can isolate the x^2 term by adding 93 to both sides:
9x^2 = 100
Finally, we can solve for x by taking the square root of both sides and considering both the positive and negative square roots:
x = ±√(100/9)
x = ±(10/3)
Therefore, the solutions to the quadratic equation are:
x = 10/3 or x = -10/3.

Chang is building a circular sandbox with a circumference of 31.4 meters. She uses a string tied to a metal stake to trace out a circle in her backyard.
Mr. Chang's string will therefore be about 10 meter long rounded to nearest meter
What exactly is pi?
The proportion of a circle's circumference to its diameter is denoted by the mathematical constant pi (). It cannot be written as a simple fraction since it is an irrational number. Pi is approximately equal to 3.141592, or 3.15.
We must first determine the circle's radius in order to determine the length of Mr. Chang's string.
C = 2πr, where C is the circle's circumference and r is its radius, is the formula for a circle's circumference.
Given that the circle's circumference is 31.4 meters, we can solve for r using the following method:
C = 2r 31.4
=2x3.14xr
= 31.4/(2x3.14)r
= 3.14/6.28r
r = 5
Thus, the circle's radius is roughly 5 meters.
The diameter of the circle, which is twice as long as its radius, will be equal to Mr. Chang's stake because it is in the center of the circle.
Mr. Chang's string will therefore be about 10 meter long rounded to nearest meter

There are two are parallel vertical lines l and m intersected by another line t making angles 1 and 3 with l and 5 and 7 with m. 1 and 4 and 2 and 3 are opposite angles at the point of intersection of l and t. 5 and 8 and 6 and 7 are opposite angles at the point of intersection of m and t. If m∠2 = 120°, what is m∠7?
Since lines l and m are parallel, we know that angles 1 and 5 are corresponding angles and are therefore congruent. Also, angles 4 and 8 are corresponding angles and are congruent.
We also know that angles 1 and 4 are vertical angles, so they are congruent, and angles 2 and 3 are vertical angles, so they are congruent.
Thus, we can set up the following equation:
m∠7 = m∠8 - m∠5 = m∠4 - m∠5
We are given that m∠2 = 120°, so we can use this to find m∠1:
m∠1 + m∠2 = 180° (since angles 1 and 2 are supplementary)
m∠1 + 120° = 180°
m∠1 = 60°
Since angles 1 and 5 are congruent, we know that m∠5 = 60°.
We are also given that angles 1 and 3 are complementary, so we can use this to find m∠3:
m∠1 + m∠3 = 90°
60° + m∠3 = 90°
m∠3 = 30°
Now we can find m∠4:
m∠1 + m∠4 = 180° (since angles 1 and 4 are supplementary)
60° + m∠4 = 180°
m∠4 = 120°
Finally, we can use these values to find m∠7:
m∠7 = m∠4 - m∠5
m∠7 = 120° - 60°
m∠7 = 60°
Therefore, m∠7 is 60°.
What do i do for a rectangle that is 8 inches long, 3 inches on the bottom, and 5 inches on the side. Help me please
The area of the rectangle is 40 square inches.
For a rectangle that is 8 inches long, 3 inches on the bottom, and 5 inches on the side, there are a few things you can do.
The perimeter of a rectangle is the sum of the lengths of all four sides.
To calculate the perimeter, add the lengths of the top and bottom sides (8 + 3 = 11) and the lengths of the two side lengths (5 + 5 = 10).
To find the area of a rectangle with an 8-inch long side, a 3-inch bottom side, and a 5-inch side, follow these steps:
Identify the dimensions of the rectangle.
The dimensions are given as 8 inches long, 3 inches on the bottom, and 5 inches on the side.
However, a rectangle only has two different side lengths, so we can assume that the 3-inch measurement is irrelevant.
Confirm the side lengths.
In this case, the side lengths are 8 inches and 5 inches. The 8-inch side is the length, and the 5-inch side is the width.
Calculate the area of the rectangle.
To find the area, multiply the length by the width. In this case, that is 8 inches (length) multiplied by 5 inches (width).
Area = Length × Width
Area = 8 inches × 5 inches
Area = 40 square inches

A donut shop wanted to determine the best price to sell its donuts. The manager of the shop gathered data from several donut shops in the city for the total cost, y, for different amounts of donuts, x. He created the following scatter plot with a line of fit.
scatter plot titled donut pricing with the x axis labeled number of donuts and the y axis labeled total cost in dollars, with points at 1 comma 1, 2 comma 2 and a half, 5 comma 3, 6 comma 5 and a half, 3 comma 2, 7 comma 5, 4 comma 4, 8 comma 4 and a half, 12 comma 7, 10 comma 7, 9 comma 7, and 8 comma 5 and a half, with a line passing through the coordinates 2 comma 2 and 7 comma 5
Find the slope of the line of fit and explain its meaning for the real-world situation.
The slope is 3 over 5, which means when 0 donuts are sold, it is predicted that the shop will earn $0.60.
The slope is 4 over 5, which means when 0 donuts are sold, it is predicted that the shop will earn $0.80.
The slope is 3 over 5, which means for each additional donut sold, the shop is predicted to earn $0.60.
The slope is 4 over 5, which means for each additional donut sold, the shop is predicted to earn $0.80
The correct answer is "The slope is 4 over 5, which means for each additional donut sold, the shop is predicted to earn $0.80."
The slope of the line of fit represents the rate of change in the dependent variable (total cost, y) with respect to the independent variable (number of donuts, x). In other words, it represents the amount by which the total cost increases or decreases for each unit increase in the number of donuts sold.
In this case, the slope of the line of fit is 4/5, which means that for each additional donut sold, the total cost is predicted to increase by $0.80. This indicates that the donut shop should expect to make a profit of $0.80 for each donut sold, assuming that all other factors remain constant. This information can be used by the donut shop to determine the optimal price to sell its donuts and maximize its profits.

Solve the following: 5x + 3x = 2(4x - 5) - 2
This statement is false. Therefore, the original equation has no solution.
How to solve an equation?
To solve the equation 5x + 3x = 2(4x - 5) - 2, we need to simplify each side of the equation using the order of operations (PEMDAS).
First, we simplify the left side of the equation by combining like terms. 5x + 3x equals 8x, so we have:
8x = 2(4x - 5) - 2
Next, we simplify the right side of the equation using the distributive property of multiplication. We multiply the 2 by each term inside the parentheses:
8x = 8x - 10 - 2
We can simplify further by combining like terms on the right side of the equation:
8x = 8x - 12
Now we have an equation with variables on both sides. To solve for x, we want to isolate the variable on one side of the equation. We can do this by subtracting 8x from both sides:
0 = -12
This statement is false. Therefore, the original equation has no solution.
The equation 5x + 3x = 2(4x - 5) - 2 is an example of a contradiction. It means that there is no value of x that makes both sides of the equation equal. In this case, we can see that the left side of the equation is always greater than or equal to the right side, no matter what value of x we choose. Therefore, the equation has no solution.

3u•V
State whether the result is a vector or a scalar.
The answer is 3u•v = 3(-6) = -18. So, the result is a Scalar
What do you mean by Scalar and Vectar quantity?In physics, a scalar quantity is a physical quantity that has only magnitude, but no direction. Examples of scalar quantities include mass, time, temperature, energy, and distance. Scalar quantities are represented by a single numerical value, and they can be added, subtracted, multiplied, and divided like regular numbers.
On the other hand, a vector quantity is a physical quantity that has both magnitude and direction. Examples of vector quantities include displacement, velocity, acceleration, force, and momentum. Vector quantities are represented by a magnitude (the size or amount of the quantity) and a direction (the orientation of the quantity in space), and they are usually written as boldface letters or with an arrow above them. Unlike scalar quantities, vector quantities cannot be added, subtracted, multiplied, or divided like regular numbers. Instead, they must be combined using vector operations such as vector addition, dot product, and cross product.
The dot product of two vectors u and v is defined as:
u•v = (u1 * v1) + (u2 * v2)
where u1 and u2 are the components of vector u, and v1 and v2 are the components of vector v.
Using this formula, we can calculate:
u•v = (7 * -2) + (2 * 4) = -14 + 8 = -6
So, 3u•v = 3(-6) = -18.

For a total of $2,400, the coach purchased 30 hoodies and 15 long sleeve shirts. A hoodie costs $60 and a long sleeve shirt is $45.
Let x represent the number of hoodies ordered and y represent the number of long sleeve shirts ordered. To describe the provided data, we may construct the following system of two equations:
x + y = 45 (because there are 45 players) (since there are 45 players)
60x + 45y = 2400 (the total cost of the order) (the total cost of the order)
We may determine that x = 30 and y = 15 by solving for x and y. As a result, the coach placed orders for 15 long sleeve jerseys and 30 hoodies. We can confirm that the total price is $2400: (30 x $60) + (15 x $45) = $1800 + $675 = $2400

what information can be inferred (deduced) from the graphs you created? can you predict what the graphs would look like if you had polled 100 people? be specific in your explanations- this answer should be 6 thoughtful sentences long.
The information inferred from the graphs includes the overall trend, frequency of responses, and distribution of data, and predicting what the graphs would look like if we polled 100 people depends on factors such as sample population, question being asked, and range of possible responses.
From the graphs created, we can infer several things such as the overall trend, frequency of responses, and distribution of the data. For instance, if the graphs depict a bell-shaped curve, we can conclude that the responses were normally distributed, and that most people fell within the average range of responses. Conversely, if the graphs show a skewed distribution, it can indicate that a particular response was more common among the participants. We can also deduce from the graphs which response was the most popular and which was the least popular.
As for predicting what the graphs would look like if we polled 100 people, it would depend on various factors such as the sample population, the question being asked, and the range of possible responses. However, we can assume that with a larger sample size, the graphs would provide a more accurate representation of the population as a whole, and the distribution of responses would be more normal.

Answer: it is one of the last two
Step-by-step explanation:
coordinates of point wjere the graph of y=4-2x crosses line y=1
Answer:
To solve this problem, we need to set the equation of the line and the equation of the given curve equal to each other and then solve for x. Once we find the value of x, we can substitute it back into either equation to find the corresponding y-coordinate. Here are the steps:
1. Set the equations equal to each other:
4 - 2x = 1
2. Solve for x:
4 - 2x - 1 = 0
3 - 2x = 0
3 = 2x
x = 3/2
2. Substitute x back into either equation to find y:
y = 4 - 2(3/2)
y = 1
Therefore, the point where the graph of y=4-2x crosses the line y=1 is at (3/2, 1).
distance between (1,5) and (-6,-2)
[tex]\:\: \:\: \:\star[/tex] We are asked to find out the distance between (1,5) and (-6,-2).We know the formula to find the distance between two points is given by -
[tex] \:\: \star \underline{ \sf{ Distance = \sqrt{ (y_2 -y_1)^2 + (x_2-x_1)^2}}}\\[/tex]
As per question, points are -
A (1,5)B(-6,-2)Now that we are given the points, so we can put them into the formula and solve for distance between them.Which is -
[tex]\:\: \:\: \:\star \underline{ \sf{ Distance = \sqrt{ (y_2 -y_1)^2 + (x_2-x_1)^2}}}\\[/tex]
[tex] \longrightarrow \sf Distance_{(AB)} = \sqrt{ (-2-5)^2 + (-6-1)^2 }\\[/tex]
[tex]\:\:\:\:\:\longrightarrow \sf Distance_{(AB)}= \sqrt{ (-7)^2 + (-7)^2 }\\[/tex]
[tex]\:\:\:\:\longrightarrow \sf Distance_{(AB)} = \sqrt{ 49+49 }\\[/tex]
[tex]\: \:\:\:\: \:\longrightarrow \sf Distance _{(AB)}= \sqrt{ 98}\\[/tex]
[tex]\: \:\:\: \:\longrightarrow \sf Distance_{(AB)} = \sqrt{49 \times 2}\\[/tex]
[tex]\:\: \:\: \:\:\longrightarrow \sf\underline{ Distance_{(AB)} = 7√2}\\[/tex]
[tex]\: \:\:\: \:\:\longrightarrow \sf Distance_{(AB) }= 9.89949......\\[/tex]
[tex]\: \:\:\: \:\:\longrightarrow \sf \underline{Distance_{(AB) }= 9.9\:(Approx)}\\[/tex]
Therefore, the distance between (1,5) and (-6,-2) is 7√2 or, 9.9 ( Approx).
