Answer:

Here the slope is 2.

Step-by-step explanation:

The first step here is to solve for y.  This will lead us to the correct slope value.  Subtracting 4x from both sides, we get -2y = 7 - 4x.

Dividing both sides by -2, we get y = -7/2 + 2x.  The coefficient of x is the slope.  Here the slope is 2.

The slope of a line parallel to the line 4x - 2y = 7 is 2. This is calculated by modifying the given equation into the form y = mx + b and determining the value of 'm', which represents the slope, and parallel lines share the same slope.

To find the slope of a line parallel to the given line, 4x - 2y = 7, we first need to put the given equation in the standard form y = mx + b, where 'm' represents the slope of the line.

We can do this by isolating 'y' in the equation. So, 4x - 2y = 7 becomes 2y = 4x - 7. Then, we divide the entire equation by 2 to solve for 'y', which gives us y = 2x - 7/2. Thus, the slope 'm' of this line is 2.

Lines that are parallel to each other have the same slope, so the slope of the line parallel to the given line is also 2.

To find out how many pounds of apples Meredith has left after 4 hours, we need to subtract the total change in apples from the original amount.

To find out how many pounds of apples Meredith has left after 4 hours, we need to subtract the total change in apples from the original amount. Let's calculate step-by-step:

To find the total change, we need to add the individual changes:

Total Change = -8.5 + (-12 2/3) + (-16 1/5) + (-10.2) = -47 61/60 pounds

Now, we subtract the total change from the original amount:

Final Amount = 85.4 - 47 61/60 pounds

Answer: B

Step-by-step explanation: Got it right on edge

Answer:B

Step-by-step explanation:I did it

Answer:

Data set B has a higher range than data set A and thus B has a higher degree of variability than A.

Step-by-step explanation:

There are several measures of variability in Statistics among them being;

The range

The inter-quartile range

Variance and standard deviation

To compare the variability of two or more sets of data, we can compute any of the above measures of dispersion and compare them across the various data sets.

In this question we have been given two data sets;

Data Set A: 18, 24, 29, 30, 39

Data Set B: 26, 29, 39, 40, 52

The simplest measure of variability or dispersion is the range. The range is defined as the difference between the maximum and the minimum values in a data set.

The range of data set A is; 39 - 18 = 21

The range of data set B is; 52 - 26 = 26

Data set B has a higher range than data set A and thus B has a higher degree of variability than A.

Supplementary angles are two angles which sum up to 180°.

Answer:

B. [tex]\angle 2\text{ and }\angle 5[/tex]

Step-by-step explanation:

We have been given an image of intersecting lines. We are asked to find the pair of angles that must be supplementary.

We know that two angles are supplementary when they add up-to 180 degrees.

Upon looking at our given image, we can see that the measure of angle 2 and measure of angle 5 is 90 degrees. So these angles will add up-to 180 degrees, therefore, option B is the correct choice.

Answer:

x1= 14/4 and X2 = -2

Step-by-step explanation:

To find the values of "X" for which when the function is evaluated gives 19 we need to equal the function to 19, as follows:

2x^2+3x+5 = 19

2x^2+3x+5-19=0

2x^2+3x-14=0

Then, solving for "x" we need to use the quadratic formula (Attached), where a, b, and c, are the following:

Why?

C) It corresponds to the 48-degree angle

Answer:

1) 48 and C) It corresponds to the 48-degree angle.

Step-by-step explanation:

Seeing the parallel lines k and l, and the transversal line m, we have that 48° and angle 1 are corresponding angles because k and l are parallel, then, the angle formed with the same transversal line will have the same measure.

So, the measure of angle 1 is 48 (option 1) and the reason is C) It corresponds to the 48-degree angle.

Answer:

100pi in^2, or 314.16 in^2 to nearest hundredth.

Step-by-step explanation:

The areas of the surface of water for  full basin and area for the surface when the depth is 10 inches are in the ratio 25^2 : 10^2 = 6.25 : 1. (because the depth of the water = radius of the water when the basin is full).

The area for a full basin =  pi r^2 = 625pi in^2.

So the area  when depth is 10 inches =  625pi / 6.25 = 100pi in^2.

Answer:

9. ∠A ≅ ∠R

10. SI ≅ GH

11. MN ≅ RN

12. FE ≅ TU

Step-by-step explanation:

Look at the reason identifier: A means "angle"; S means "side". The order is important. AAS means two adjacent angles with only one of them next to the corresponding sides. SAS means the angle is between two corresponding sides.

9. Sides CS and TS correspond and are congruent. The vertical angles at S are congruent, so the AAS identifier means you're looking for angles A and R to be congruent. (Using angles C and T would invoke the ASA identifier.)

__

10. Sides HI are congruent; the angles at H and I are congruent. The SAS identifier means you're looking for the sides on the other side of those angles to be congruent: sides SI and GH.

__

11. SSS means you're claiming all three sides are congruent to their corresponding sides. The common side is congruent to itself; the marked sides are congruent. So, you need the unmarked sides to be congruent to each other.

__

12. HL means you're claiming the hypotenuse and one leg of the right triangle are congruent. One leg is already marked, so you need the hypotenuses to be congruent.

Polygons are categorized according to their side count. The following are the designations for polygons depending on the number of sides they exhibit:

3 sides: Triangles

4 sides: Quadrilaterals

Special cases of quadrilaterals include rectangles, squares, parallelograms, rhombuses, and trapezoids.

5 sides: Pentagons

6 sides: Hexagons

7 sides: Heptagons or Septagons

8 sides: Octagons

9 sides: Nonagons

10 sides: Decagons

Polygons are classified based on the number of sides they possess. Here are the names for polygons with different numbers of sides:

Triangles: The simplest polygon with three sides, often classified based on angles as equilateral, isosceles, or scalene.

Quadrilaterals: Four-sided polygons, encompassing various shapes with specific characteristics. For example, squares have equal sides and right angles, while rectangles have opposite sides of equal length and right angles.

Pentagons: Five-sided polygons, commonly found in geometry and nature.

Hexagons: Six-sided polygons frequently seen in beehives and some crystal structures.

Heptagons or Septagons: Seven-sided polygons, less commonly encountered in everyday geometry.

Octagons: Eight-sided polygons, often used in architecture and design.

Nonagons: Nine-sided polygons, less commonly discussed but still defined geometrically.

Decagons: Ten-sided polygons, exhibiting symmetry and regularity in shape.

A frequency polygon is a statistical tool used in mathematics to represent the distribution of data visually, much like a line graph, but specifically connected to a histogram. They are particularly helpful for interpreting continuous data and spotting trends within datasets.

Although the question seems to be incomplete, it appears to ask about the terminology used in mathematics, particularly pertaining to polygons. However, if we connect the dots with the provided reference, it seems the actual topic is 'frequency polygons' in the context of statistics. A frequency polygon is a graphical representation of data in statistics, where it's used to illustrate the distribution of a dataset and is similar to a line graph. It is typically made by connecting the midpoints of the tops of bars of a histogram with straight lines, making the data visually easy to interpret. By doing so, it helps in understanding how values are distributed over an interval and is often used to compare different sets of data on the same graph.

Continuous data can sometimes be difficult to analyze, but frequency polygons simplify this by offering a clear, visual interpretation. They are helpful in identifying trends and patterns in data which are not immediately obvious when looking at a table of values or a histogram alone.

Answer:

A.

Step-by-step explanation:

First, let's define the types of numbers.

Real numbers: a value that represents a quantity along a continuous line

ex: 1, 5, -6, 0.125, 45.5258,

Integer: Zero, any positive or negative number

ex: -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5....

Whole numbers: a number without fractions [not negative]

ex: 0, 1, 2, 3, 4, 5.....

Rational numbers: any number that can be expressed as the quotient or fraction

ex: 1, 2, 3, 4, 5

Irrational numbers: any number that can't be expressed at the quotient or fraction

ex: pi, [3.14.... (never ending decimal)]  square root of 2....

Based on this information, the false statment would be A. I believe, because

pi is a real number and it is an irrational number.
