The type of triangle AABC is an equilateral triangle, as it is formed by the midsegments of the equilateral triangle ADEF.

Since the midsegments of a triangle are parallel to its opposite sides and half the length of the opposite sides, the midsegments of an equilateral triangle are congruent to each other, and their length is half the length of the sides of the equilateral triangle.

Suppose we've two endpoints of a line segment as:

A(p,q), and B(m,n)

Then let the midpoint be M(x,y) on that line segment. Then, its coordinates are:

[tex]x = \dfrac{p+m}{2} and y = \dfrac{q+n}{2}[/tex]

We are given that;

An equilateral triangle DEF

AAB is formed by the midsegments of triangle ADEF, which means that AAB is also an equilateral triangle. To see why this is true, we can use the following argument:

The midsegment of DE is parallel to AB and has half the length of AB.

The midsegment of EF is parallel to AA' and has half the length of AA'.

The midsegment of FD is parallel to BB' and has half the length of BB'.

Therefore, AB = AA' = BB', and the angles at A and B are both 60 degrees (since DEF is equilateral).

Thus, AAB is an equilateral triangle, because all its sides are equal in length and all its angles are equal to 60 degrees.

Therefore, by midpoint the answer will be equilateral triangle.

The volume generated by rotating the region bounded by curves x = √y, x= 0 and y = 6 about the x-axis is 24π cubic units.

To use the method of b, we will imagine taking thin slices parallel to the axis of rotation and adding up their volumes.

To use the method of cylindrical shells, we need to determine the height and radius of each cylindrical shell. We will take thin vertical slices parallel to the y-axis.

The height of each cylindrical shell will be dy. The radius of each cylindrical shell will be x, which is equal to √y.

The volume of each cylindrical shell will be:

[tex]dv = 2\pi x * dy[/tex]

Substituting x = √y, we get:

The required equivalent expression using the distributive property is: [tex]$$\boxed{21r + 49s - 28}$$[/tex]

This principle states that multiplying the sum of two or more addends by a number will produce the same outcome as multiplying each addend by the number separately and then adding the results together.

Using the distributive property, we can distribute the factor of 7 to each term inside the parentheses:

7(3r + 7s - 4) = 7(3r) + 7(7s) - 7(4)

Simplifying each term:

The GCF of p² and q² is 25. And the explanation is mentioned below.

The acronym GCF means "Greatest Common Factor." It is often referred to as the "Highest Common Factor" or the "Greatest Common Divisor" (GCD) (HCF). The biggest number that divides two or more other numbers without producing a residue is known as the GCF.

If the GCF of two numbers p and q is 5, then we can express the numbers as:

p = 5a

q = 5b

where a and b are integers, and 5 is the greatest common factor.

Now, let's consider p² and q²:

p² = (5a)² = 25a²

q² = (5b)² = 25b²

We can factor out 25 from both expressions:

p² = 25(a²)

q² = 25(b²)

Notice that the expression for p² has a factor of 25 and a factor of a², while the expression for q² has a factor of 25 and a factor of b².

Since the GCF of p and q is 5, we know that a and b do not have any common factors besides 1 and 5.

Therefore, a² and b² also do not have any common factors besides 1 and 5.

This means that the GCF of p² and q² is simply the factor of 25 that they have in common, which is 25.

So, the GCF of p² and q² is 25.

The p-value for this sample is approximately 0.004655 which is smaller than the significance level of 0.005. This means that we reject the null hypothesis and conclude that there is evidence to support the alternative hypothesis that the population proportions are not equal.

To test the hypothesis Hₐ : p₁ ≠ p₂ at a significance level of α = 0.005, we can use the two-sample z-test for proportions, where the test statistic is given by:

z = (p₁ - p₂) / sqrt{p(1-p)(1/n₁ + 1/n₂)}

where p = (x₁ + x₂) / (n₁ + n₂) is the pooled sample proportion, x₁ and x₂ are the number of successes in the two samples, n₁ and n₂ are the sample sizes for the two samples, and p₁ and p₂ are the sample proportions for the two samples.

Plugging in the given values, we have:

p₁ = 119/687 ≈ 0.1732

p₂ = 137/577 ≈ 0.2374

n₁ = 687

n₂ = 577

p = (119 + 137) / (687 + 577) ≈ 0.202

z = (0.1735 - 0.2376) / √{0.202 * (1 - 0.202) * (1/687 + 1/577)} ≈ -2.83

The test statistic for this sample is approximately -2.83

To find the p-value for this sample, we need to find the probability of observing a test statistic as extreme as -2.83, assuming that the null hypothesis is true. Since this is a two-tailed test, we need to find the area in the tails of the standard normal distribution that corresponds to a significance level of 0.005:

α/2 = 0.005/2 = 0.0025

Using a standard normal table or a calculator, we can find that the z-score corresponding to an area of 0.0025 in the left tail of the standard normal distribution is approximately -2.81. The z-score corresponding to an area of 0.0025 in the right tail is approximately 2.81.

The p-value for this sample is the sum of the areas in the tails beyond the test statistic:

p-value = P(Z ≤ -2.83) + P(Z ≥ 2.83)

P = 0.004655

Assuming "she" in the question is a typo and it should be "if", here's the solution:

If the population of a small town is 567, and it decreases at a rate of 1.5% per year, we can find the population after 20 years using the formula:

P = 567 * (1 - 0.015)^20

where P is the population after 20 years.

Simplifying this expression, we get:

P = 567 * 0.742 = 420.414

Rounding this to the nearest whole number, we get:

P ≈ 420

Therefore, after 20 years, the population of the small town would be approximately 420.

The function has an infinite solution.

A unique kind of relation called a function is one in which each input has precisely one output. In other words, the function produces exactly one value for each input value. The graphic above shows a relation rather than a function because one is mapped to two different values.

The relation above would turn into a function, though, if one were instead mapped to a single value. Additionally, output values can be equal to input values.

The x-values are input into the function machine. The function machine then performs its operations and outputs the y-values. The function within can be any function.

Since f(x) and g(x) are the same function, their graphs will be the same and all points on the line are solutions. All x values will be solutions. This means there are infinitely many.

Therefore , the solution of the given problem of linear equation comes out to be y= (3/2)x + 5 .

The equation y=mx+b is the basis of a linear regression model. B is the slope, and m is the y-intercept. The aforementioned sentence is repeatedly alluded to as a "math problem with two variables," despite the fact that y and y are distinct parts. In bivariate linear equations, there are only two variables. The application regions for linear equations have no definitive solutions.

Here,

We must first determine the slope of the line before using the point-slope form of the equation of a line to determine the equation of the line that goes through two points.

The angle of the line that connects the coordinates (2, 8) and (8, 7) is:

=> slope = (−7 − 8) / (−8 − 2)

=> slope = −15 / −10

=> slope = 3/2

When we express the equation of a line in the point-slope format, where (x1, y1) is one of the line's points and m is its slope, we get the following result:

=> y − y1 = m(x − x1)

By selecting the line's origin (2, 8) and substituting the slope m = 3/2, we obtain:

=> y − 8 = (3/2)(x − 2)

The equation y = mx + b is transformed into the slope-intercept form by condensing and reordering the variables.

=> y = (3/2)x + 5

Consequently, y = (3/2)x + 5 represents the equation of the line going through the points (2, 8) and (8, 7) respectively.

What is the standard deviation?

When we measure diversity in a data set, it is called standard deviation. We have to calculate the variance first. The square root of variance gives the standard deviation. The formula to calculate standard deviation is:

s= [tex]\sqrt{\frac{(x1-xm)^{2} + (x2-xm)^{2} +........+ (xn-xm)^{2} }{n-1} }[/tex]

First, we will calculate the mean of the data, xm

[tex]xm=\frac{18+22+39+48+77+89}{6}[/tex]

      [tex]=48.83[/tex]

Then, we will calculate the following:

[tex](x1-xm)^{2}=(18-48.83)^{2} \\\\(x2-xm)^{2}=(22-48.83)^{2} \\\\(x3-xm)^{2}=(39-48.83)^{2} \\\\(x4-xm)^{2}=(48-48.83)^{2} \\\\(x5-xm)^{2}=(77-48.83)^{2} \\\\(x6-xm)^{2}=(89-48.83)^{2} \\[/tex]

This simply means that the x-axis moves to the left by 4 points and that the y-axis moves down 3 points. (if it was a plus not minus then points would move up and to the right)

1) Move the x-axis

We can see that the x-axis of b is 5. To move it to the left 4 we subtract 5 by 4

2) Move the y-axis

We can see that the y-axis of b is 1. To move it down we subtract 1 by 3

Answer:

y = -4x + 5.

Step-by-step explanation:

The slope-intercept form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept.

Given that the line passes through the point (2, -3) and has a slope of -4, we can use the point-slope form of a linear equation to find the y-intercept:

y - y1 = m(x - x1)

where x1 and y1 are the coordinates of the given point, and m is the slope.

Substituting the given values, we get:

y - (-3) = -4(x - 2)

Simplifying and rearranging, we get:

y + 3 = -4x + 8

Subtracting 3 from both sides, we get:

y = -4x + 5

Therefore, the equation in slope-intercept form for the given line is y = -4x + 5.

The multiple of the unit fraction 3/8​ is 15/40.

What is fraction ?

A fraction is a number that represents a part of a whole. It is a way of representing a quantity that is not a whole number. Fractions are written with two numbers, one above the other and separated by a horizontal line. The number above the line is called the numerator, and the number below the line is called the denominator.

To find the multiple of a fraction, you simply multiply the numerator and the denominator by the same number. For example, to find the multiple of 3/8, you can multiply both the numerator and the denominator by 2:

3/8 * 2/2 = 6/16

So the multiple of 3/8 by 2 is 6/16.

Similarly, you can find the multiple of 3/8 by any other number by multiplying both the numerator and denominator by that number. For instance, if you want to find the multiple of 3/8 by 5, you can multiply both the numerator and the denominator by 5:

3/8 * 5/5 = 15/40

Therefore, the multiple of the unit fraction 3/8​ is 15/40.

After a successful mating season, young are produced. Change occurs continuously in an economy that is growing. We are unable to remark, "It changed here," in reference to an occurrence. The pattern is always changing (radioactive decay, a bacteria colony, or perfectly compounded interest).
