Slope intercept form:

y=mx+b

Where:

m= slope (rise y /run x )

b= y-intercept ( where the line crosses the y- axis )

m=1/3

b= -3

Replacing:

y= 1/3x-3

So, the line crosses the y- axis at y=-3, and since the slope is positive the line increases 1 unit up, by every 3 units to the right along the x axis.

Answer:

C. 3x + 2y = 12

explanation:

The solution to the variable x is 12 and the measure of ∠B is 48°.

∠A = 5x−12°

∠B = 2x+24°

Angle A and Angle B are congruent angles.

Congruent angles are angles with the same or equal measures.

So,

∠A = ∠B

5x - 12 = 2x + 24

5x - 2x = 24 + 12

3x = 36

divide both sides by 3

x = 36/3

x = 12

So therefore,

∠A = 5x−12°

= 5(12) - 12

= 60 - 12

= 48°

∠B = 2x+24°

= 2(12) + 24

= 24 + 24

= 48°

Therefore, since ∠A and ∠B are congruent, the measure of ∠A and ∠B is 48° respectively.

450 is the maximum possible number of points of intersection of these fifty segments that could lie in the interior of the first quadrant.

When two or more lines when crossing each other in a same plane, then these lines are called as intersecting lines. The intersecting lines share a common point, which exists on all the intersecting lines, and is known as the point of intersection. Point of intersection means the point at which where the two lines intersect each other.

We can pick any two points on the xx-axis and any two points on the yy-axis to form a quadrilateral, and the intersection of its diagonals will thus definitely be inside the first quadrant.

P-value of a hypothesis test is an important measure of the strength of evidence against the null hypothesis and helps us make informed decisions about rejecting or failing to reject the null hypothesis.

A hypothesis test is a statistical method used to test the validity of an assumption or a hypothesis about a population based on a sample data.

The correct answer is b. The P-value of a hypothesis test is the probability of observing a sample statistic more extreme than the one actually obtained, assuming the null hypothesis is true.

In hypothesis testing, we start with a null hypothesis, which is usually denoted as H_0, that represents the status quo or the default assumption. The alternative hypothesis, denoted as H_a, represents the opposite of the null hypothesis.

The P-value is the probability of observing a sample statistic more extreme than the one actually obtained, assuming the null hypothesis is true. A low P-value indicates that the sample data provides strong evidence against the null hypothesis, and we reject the null hypothesis.

A high P-value indicates that the sample data does not provide strong evidence against the null hypothesis, and we fail to reject the null hypothesis.

In mathematical terms, the P-value is calculated as the probability of observing a test statistic Z that is more extreme than the one actually obtained, assuming the null hypothesis is true.

The volume of the solid is 207.23 cm³.

Volume of the Solid:

Volume is the area occupied by an object/matter (solid, liquid, gas) within a 3D object. Alternatively, the volume of a three-dimensional object is generally defined as the capacity of the object that matter can hold.

For example, the volume of a cubic box indicates how much water or other substance it can contain. For ice cream cups, the amount of ice cream that can fit in the cup without gaps corresponds to the volume of the ice cream cup.

Now, based on the question:

Volume of Solid = Volume of Cylinder + Volume of Cone

Volume of Cylinder = πr²h

v= 3.14 * (3)² * 6

v = 169.56

Volume Of Cone:

Cone volume defines the space or volume of the cone. A cone is a three-dimensional geometric shape with a circular base that tapers from a flat base to a point called an apex or vertex. A cone is formed by a series of line segments, half-lines, or lines connecting vertices that are common to all points on the base in a plane that does not contain vertices. A cone can be thought of as a series of noncongruent disks that overlap each other such that the ratios of the radii of adjacent disks are kept constant.

We know that :

Volume of Cone = πr² h/3

v = 3.14 * (3)² * 4/3

v = 37.7

Now,

Volume of Solid = 169.56 + 37.7

There is evidence of a negative correlation between systolic blood pressure and heart rate. In a sample of 200 patients, a sample correlation of -0.057 was found. Correlation is a statistical measure used to assess the degree to which two variables are related to one another. A correlation coefficient ranging from -1 to 1 is used to represent this relationship. A negative correlation exists when two variables move in opposite directions.

It means that as one variable increases, the other variable decreases or vice versa.In the given case, there is evidence of a negative correlation between systolic blood pressure and heart rate because the sample correlation is -0.057. This value indicates that there is a small negative correlation between systolic blood pressure and heart rate. Systolic blood pressure is the amount of pressure exerted by blood against the walls of the arteries when the heart pumps. It is the top number in a blood pressure reading.

When your heart beats and pushes blood out, the systolic pressure is created.Heart rate is the number of times your heart beats per minute. It is also known as the pulse rate. It represents the number of times your heart contracts and relaxes with each heartbeat.

None of the statements a, b, c, or d can be determined to be true based solely on x ⇒ y and y ⇒ z.

Given that x ⇒ y and y ⇒ z, we can determine the valid implication between x and z.

To evaluate the possible truth values, let's consider the following cases:

If x is true and y is true:

Since x ⇒ y, the implication holds.

If y ⇒ z, the implication holds.

Therefore, z can be true in this case.

If x is true and y is false:

Since x ⇒ y, the implication does not hold.

The truth value of y ⇒ z is not relevant in this case.

Therefore, we cannot determine the truth value of z.

If x is false:

Since x ⇒ y, the implication holds vacuously, regardless of the truth value of y.

The truth value of y ⇒ z is not relevant in this case.

Therefore, we cannot determine the truth value of z.

Based on the above analysis, we cannot definitively conclude the truth value of z from the given information. Therefore, none of the statements a, b, c, or d can be determined to be true based solely on x ⇒ y and y ⇒ z.

In probability theory, a Venn diagram is a diagrammatic representation of sets that shows all possible logical relations between them. Venn diagrams are widely used in probability and statistics to visualize the relationship between different sets of data.

The given Venn diagram shows the relationship between three sets, A, B, and C. In order to calculate probabilities using a Venn diagram, we need to know the number of elements or members in each set, as well as any overlapping regions.

We can then use these numbers to calculate the probability of different outcomes.Let's consider two possible probabilities from the given Venn diagram:1.

The probability that an element is in set A and set B but not in set C is 0.1/0.5 = 0.22. The probability that an element is in set B or set C but not in set A is 0.2/0.6 = 1/3The first probability can be calculated by dividing the number of elements in the overlapping region of sets A and B (which is 0.1) by the total number of elements in set B (which is 0.5).

This gives us a probability of 0.22 or 22%.The second probability can be calculated by dividing the number of elements in the union of sets B and C (which is 0.2) by the total number of elements in either set B or set C (which is 0.6). This gives us a probability of 1/3 or approximately 33%.

Therefore, the correct probabilities are:1.

The probability that an element is in set A and set B but not in set C is 0.1/0.5 = 0.22.

The probability that an element is in set B or set C but not in set A is 0.2/0.6 = 1/3

Area of the sector in red = 177.87 cm²

Area of the sector in blue = 437. cm²

Step-by-step explanation:

Area of the sector = \(\frac{\theta}{360}(\pi )(r)^2\)

Area of the sector shaded in blue = \(\frac{256}{360}(\pi )(14)^2\)

                                                        = 437.87 cm²

Central angle formed by sector shaded in red = 360 - 256 = 104°

Area of the sector shaded in red = \(\frac{104}{360}(\pi )(14)^2\)

                                                      = 177.884

                                                      ≈ 177.88 cm²

Therefore, area of the sector shaded in red = 177.87 cm² and area of the sector in blue = 437.88 cm²
