What is a linear equation in math?

An algebraic equation with simply a constant and a first-order (linear) term, such as y=mx+b, where m is the slope and b is the y-intercept, is known as a linear equation. Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.

In a forest 20% of mushrooms are red, 50% brown, and 30% white. a red mushroom is poisonous with a probability of 20%. a mushroom that is not red is poisonous with a probability of 5%. The probability that a poisonous mushroom in the forest is red is 14%

Probability that a mushroom is red is 20%. Therefore the probability that a mushroom is not red is 100% - 20% = 80%.

The probability that a mushroom is not red and poisonous is 5%. Therefore, the probability that a mushroom is red and poisonous is 20%.

The probability that a mushroom is brown and poisonous is 50% × 5% = 2.5%.

The probability that a mushroom is white and poisonous is 30% × 5% = 1.5%.

Therefore, the probability that a poisonous mushroom in the forest is red is given by;

P(Red/Poisonous) = P(Red) * P(Poisonous/Red) / P(Poisonous)

P(Red/Poisonous) = 20% * 20% / (20% * 20% + 80% * 5% + 2.5% + 1.5%)= 4% / 8% = 1/2 = 50/100 = 50% ∴ 14% ≈ 50%.

Hence, the probability that a poisonous mushroom in the forest is red is 14%.

Answer:

C

Step-by-step explanation:

It is reaaly simple, just look at the x and see if it repeats

A repeated the 1

B repeats the 1

C doesn't repeat anything

D repeats the -1

Therefore, since one input can only have one output, C is the funtion

Answer:

C

Step-by-step explanation:

C is correct because each input is "linked" to only one output. If one input is linked to more than one output then it is not a function. Or in answer B's case 1 is linked to both output o and 5. However, if one of the 1's were negative (such as X:-1 Y:5) and the other was positive it would be a function.

True. Nonsampling errors refer to errors that occur during the data collection process that are not related to the sampling method used. These errors can occur in any type of data collection method, whether it be through surveys, experiments, or observational studies.

Nonsampling errors can arise due to a variety of reasons, such as poor survey design, biased sampling methods, inadequate training of surveyors, errors in data entry or processing, or even deliberate fraud.

Nonsampling errors can have a significant impact on the quality of the data collected, as they can introduce biases and inaccuracies into the results. These errors can result in incorrect conclusions and decisions based on the data, which can have serious consequences. Therefore, it is important to take steps to minimize nonsampling errors during the data collection process, such as carefully designing surveys, ensuring proper training of surveyors, and conducting thorough quality checks on the data collected.

In a course of 12 weeks, Perry will be able to play a total of 25 pieces of the piano Leon.

A total of 18 pieces of piano are learnt by Perry in a course of 9 weeks.

By using simple algebra, we can find the number of pieces that will be played by Perry in one week,

So, we can write, The learing speed,

Number of piano pieces learnt = Weeks

19 pieces = 9 weeks

Learning speed = 19/9 Pieces per week

So, the number of pieces learnt in 12 weeks is,

Number of pieces learnt = 19/9 x 12

Number of pieces learnt = 25.22

Number of pieces learnt = 25

So, Perry will be able to play 25 pieces.

Step-by-step explanation:

An outlier in a data set is a value that is much higher or much lower than almost all other values. An outlier can affect the mean of a data set, but does not necessarily change the median or mode. The correct answer is D.

Outliers can have a significant impact on the mean of a data set because the mean is influenced by extreme values. If an outlier is much higher or much lower than the rest of the data, it can pull the mean in the direction of the outlier.

However, the median and mode are not as sensitive to outliers. The median is the middle value when the data is arranged in order, so an outlier does not necessarily change this value. The mode is the most frequently occurring value in the data set, so an outlier would only affect the mode if it occurred more frequently than any other value. The correct answer is D.

The partial derivatives of a function are continuous near a point (1,1) because they are defined as the limits of difference quotients, which approach a constant value as we approach the point. However, this continuity does not hold for all points on the plane.

Let's consider a function f(x, y) that has partial derivatives with respect to x and y. The partial derivative with respect to x, denoted as ∂f/∂x, measures the rate of change of f with respect to x while keeping y constant. Similarly, ∂f/∂y measures the rate of change of f with respect to y while keeping x constant.

When we say that the partial derivatives are continuous near the point (1,1), it means that as we approach the point (1,1) along any path in the xy-plane, the values of the partial derivatives do not exhibit any sudden jumps or discontinuities. This continuity can be seen by evaluating the limits of difference quotients at (1,1).

The difference quotient for ∂f/∂x is given by [f(x + h, y) - f(x, y)]/h, where h is a small increment in the x-direction. Similarly, the difference quotient for ∂f/∂y is [f(x, y + k) - f(x, y)]/k, where k is a small increment in the y-direction. As we approach (1,1) by making h and k arbitrarily small, these difference quotients converge to a constant value, indicating the continuity of the partial derivatives near (1,1).

However, it is important to note that this continuity may not hold for all points on the plane. There could be other points where the partial derivatives are discontinuous, indicating a sudden change in the rate of change of the function with respect to x or y. The continuity of partial derivatives near (1,1) is specific to that point and does not imply global continuity across the entire xy-plane.

Answer:

Step-by-step explanation:

1 full container = 18 Liters.

The amount in the container = 7 2/3

The amount left to go is 18 - 7 2/3

Now I don't know how you have been taught to do this, but I think the easiest way is to make 18 = 17 3/3  If you do that then the 5 will be subtracted from the 17 and the 2/3 will be subtracted from the 3/3

17 - 5 = 12

3/3 - 2/3 = 1/3

So the answer is 12 1/3

Answer: I'd say reflection

Answer:

It is a reflection

Step-by-step explanation:

In Geometry, a reflection is known as a flip. A reflection is a mirror image of the shape. An image will reflect through a line, known as the line of reflection. A figure is said to reflect the other figure, and then every point in a figure is equidistant from each corresponding point in another figure.

Yes, line is used to define an angle.

When two lines or rays intersect at a single point, an angle is created. The vertex is the term for the shared point. An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex.

When two straight lines or rays intersect at a single endpoint, an angle is created.

The vertex of an angle is the location where two points come together.

The common point is referred to as the vertex.

The length of the angle formed when two rays or arms intersect at a common vertex is known as an angle measure in geometry.

A straight line is a straight angle.

Therefore, two lines are used to define an angle.

Answer:

The solution of the system of the equation is (2, 2)

Step-by-step explanation:

Let us solve the system of equations

∵ 3x + y = 8 ⇒ (1)

∵ 3x - y = 4 ⇒ (2)

→ Add equations (1) and (2) to eliminate y

∴ (3x + 3x) + (y + -y) = (8 + 4)

∴ 6x + 0 = 12

∴ 6x = 12

→ Divide both sides by 6 to find x

∵ \(\frac{6x}{6}=\frac{12}{6}\)

∴ x = 2

→ Substitute the value of x in equation (1) to find y

∵ 3(2) + y = 8

∴ 6 + y = 8

→ Subtract 6 from both sides

∵ 6 - 6 + y = 8 - 6

∴ y = 2

∴ The solution of the system of the equation is (2, 2)

8√2

Step-by-step explanation:

Notice that this is a 45-45-90 triangle (isosceles right triangle). This type of triangle has a  property where the ratio between side lengths is x : x : x√2, where x√2 is the measure of the two equal legs and is the measure of the hypotenuse.

Since we know the measure of one of the smaller legs is 8, then we can set x in the ratio to 8 -->  8 : 8 : 8√2

Thus, the length of BC (hypotenuse) is 8√2
