The third side of the triangle can have any one of the following lengths:

2 cm < third side < 10 cm.

The triangle inequality theorem, which asserts that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side, must be applied in order to find the potential lengths of the third side of the triangle.

We have sides of 6 cm and 4 cm in this instance. Hence, the third side's length must be smaller than the sum of the first two sides and bigger than the difference between them.

Contrast: 6 - 4 = 2 cm

Sum: 6 + 4 = 10 cm

As a result, the following are potential lengths for the triangle's third side:

Third side: 2 cm; length: 10 cm

Hence, the third side could be any length that falls within the range of 2 cm and 10 cm (exclusive).

Using the expected value of probability formula, the value of  Σ[x•P(x)] is -0.65

The expected value of a probability distribution is a measure of the central tendency of the distribution. It is also known as the mean or the average value of the distribution.

To calculate the expected value, we multiply each possible outcome by its corresponding probability and then sum up the products. Symbolically, if X is a random variable with possible outcomes x1, x2, ..., xn and probabilities p1, p2, ..., pn, then the expected value of X, denoted E(X), is given by:

[tex]E(X) = \sum_{i=1}^{n} x_i p_i[/tex]

To find Σ[x•P(x)] we need to multiply each x-value by its corresponding probability and then sum up the products.

So we have:

Σ[x•P(x)] = (-1)(0.999) + (349)(0.001)

Σ[x•P(x)] = -0.999 + 0.349

Σ[x•P(x)] = -0.65

Therefore, Σ[x•P(x)] is equal to -0.65.

Answer:

-1, -6, 13, 20 is an arithmetic sequence
d = 7

5, 12, 19, 26 is arithmetic sequence

d = 7

-3 - 9, -27, -81 is not an arithmetic sequence

Step-by-step explanation:

Common difference is the difference between successive terms and must be the same for all terms

-1, -6, 13, 20 is an arithmetic sequence with common difference:
6 - (-1) = 13 - 6 = 20 - 13 = 7

5, 12, 19, 26 is arithmetic sequence with common difference
12- 5 = 19 - 12 = 26 - 19 = 7

-3 - 9, -27, -81 is not an arithmetic sequence
The difference between successive terms is not the same
-9 - (-3) = -9 + 3= -6

but

-27 - (-9) = -27 + 9 = -18

In fact it is a geometric sequence where each term = x previous term

-9 = 3 x -3

-27 = 3 x -9

The slope of the image of the original line y = 2x - 4 after the transformation (x,y) (-x, -y) is -2.

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

The slope of the original line y = 2x - 4 is 2.

To find the slope of the image after the transformation, we can apply the transformation rule to two points on the original line, and then find the slope of the line passing through the images of those two points.

Let's choose two points on the original line:

Point 1: (0, -4)

Point 2: (1, -2)

Now we apply the transformation rule to each of these points:

Point 1 image: (-0, -(-4)) = (0, 4)

Point 2 image: (-1, -(-2)) = (1, 2)

The images of these two points lie on the line y = -2x + 4. The slope of this line is -2.

Therefore, the slope of the image of the original line y = 2x - 4 after the transformation (x,y) (-x, -y) is -2.

An organized representation of the data is all that the graph is. It facilitates our understanding of the facts. Data is the term used to describe the numerical information obtained through observation.

The modification looks like this.

Combining two transformations results in the transformation of

h(x) to -h(x) -4.

1. An X-axis-centered reflection. Every point (x, y) in h(x) is transformed into (x', y'), where x' = x and y' = -y. Hence, (x, y) (x, -y)

2. A 4-unit translation of each reflected point, where the x value remains constant, but the y value is translated downward to become y'-4 = -y -4

Every coordinate (x, y) in h(x) will be transformed to the following as a result of both transformations: (x, -y -4)

Given that the graph is made up of two straight lines that intersect at the origin, all we need to do is select any three points in h(x), determine their transformed coordinates, and then connect them using straight lines: h(x0 -h(X) - 4 (-2, 4) (-2, -4-4) =(-2, -8) (0, 0) (0, -0 - 4) =(0, -4) (4, 2) (4, (4, -6)

Answer:

First, we need to calculate the total number of payments Ryan will make over 10 years, which is 10 years x 12 months/year = 120 months.

Next, we can use the formula for the present value of an annuity to calculate the maximum price of the boat:

PV = PMT x [1 - (1 + r/n)^(-nt)] / (r/n)

where PV is the present value, PMT is the monthly payment, r is the annual interest rate, n is the number of compounding periods per year, and t is the number of years.

Plugging in the values we have:

PMT = $500

r = 0.13

n = 12 (since the loan is monthly)

t = 10

PV = $500 x [1 - (1 + 0.13/12)^(-12x10)] / (0.13/12)

PV = $44,484.72

Therefore, the maximum price for a boat that Ryan's budget can afford, rounded to the nearest hundred dollars, is $44,500.

There are no real numbers, actual solutions to the equation |x| = -5/8.

Several mathematical disciplines, including calculus, algebra, geometry, and number theory, employ the absolute value function. By removing the sign from a number or changing a complicated expression into a simpler one, it is frequently used to simplify expressions and equations. The distance between two points in n-dimensional space, where n is any positive integer, is also defined using the absolute value function. The absolute value function is also employed in many mathematical applications, including physics, engineering, economics, and finance, where it is utilised to describe quantities that can only have non-negative values.

The distance from the sun to the earth is approximately 150 million km.

To convert this to meters, we can multiply by 1,000 to get 150 billion meters (1 km = 1000 m).

Using the speed of light of 300 million m/s, we can calculate the time it takes for light to travel from the sun to the earth by dividing the distance by the speed of light:

Time = Distance / Speed of light

Time = 150,000,000,000 m / 300,000,000 m/s

Time = 500 seconds

Therefore, it takes about 500 seconds or 8.3 minutes for a beam of light to travel from the sun to the earth.

Since the p-value (0.72) is greater than the significance level (0.05), we fail tο reject the null hypοthesis.

The null hypοthesis is  statement that assumes there is nο significant difference between twο οr mοre sets οf data. It is statement that can be tested and either accepted οr rejected based οn statistical evidence.

Tο test whether the number οf resignatiοns is unifοrm οver the fοur seasοns, we can use the chi-squared gοοdness οf fit test. The null hypοthesis fοr this test is that the number οf resignatiοns is unifοrm οver the fοur seasοns

Here are the steps tο perfοrm the chi-squared gοοdness οf fit test:

Determine the expected frequencies:

Tο determine the expected frequencies, we need tο assume that the null hypοthesis is true. Since there are fοur seasοns, each seasοn is expected tο have 1/4 οf the tοtal number οf resignatiοns. Therefοre, the expected frequency fοr each seasοn is 60/4 = 15.

Calculate the test statistic:

The test statistic fοr the chi-squared gοοdness οf fit test is calculated using the fοrmula:

χ²=∑(O-E)²/E

Using the οbserved frequencies, we get:

χ² = (20 - 15)²/15 + (15 - 15)²/15 + (10 - 15)²/15 + (15 - 15)²/15

= 1.33

Determine the p-value:

The p-value fοr the calculated test statistic is 0.72.

Make a decisiοn:

Since the p-value (0.72) is greater than the significance level (0.05), we fail tο reject the null hypοthesis.
