The average age of a breed of dog is 19. 5 years. If the distribution of their ages is normal and 20% of dogs are older than 22. 6 years, find the standard deviation
The standard deviation of the ages of this breed of dog is approximately 4.4 years.
To find the standard deviation, we can use the concept of z-scores and the cumulative distribution function (CDF) of a standard normal distribution. Let's denote the average age as μ (mu) and the standard deviation as σ (sigma).
Given that the average age of the breed is 19.5 years, we can set μ = 19.5. We are also given that 20% of the dogs are older than 22.6 years. Using the z-score formula, we can calculate the z-score corresponding to this percentile:
z = (x - μ) / σ
Where x is the given value (22.6 years) and z is the z-score. Rearranging the formula, we can solve for σ:
σ = (x - μ) / z
Plugging in the values, we have:
σ = (22.6 - 19.5) / z
To find the z-score corresponding to the 20th percentile, we can use the inverse CDF of the standard normal distribution. Using statistical software or a z-table, we find that the z-score corresponding to the 20th percentile is approximately -0.84.
Substituting the values, we get:
σ = (22.6 - 19.5) / -0.84 ≈ 3.7 / -0.84 ≈ -4.4

The values of a and b from the quadratic equation x² + (13/2)*x + 15/2 = 0 are:a = -10/13 and b = -3/13 respectively.
How to solve the quadratic equation?For a general quadratic equation:a*x² + b*x + c = 0
The solutions are:
\(x = \frac{-b \pm \sqrt{b^2 - 4ac} }{2a}\)
In this case, we have the quadratic equation:
x² + (13/2)*x + 15/2 = 0.
Replacing that in the quadratic formula for the solutions, we will get:
\(x = \frac{-13/2 \pm \sqrt{(13/2)^2 - 4*1*15/2} }{2*13/2}\\\\
x = \frac{-6.5 \pm 3.5 }{13}\)
Then the two solutions are:
x = (-6.5 - 3.5)/13
= -10/13
x = (-6.5 + 3.5)/13
= -3/13
Therefore, the solution to the quadratic equation is = -10/13 and b = -3/13

How were the planets in the solar system formed?
Answer: The Sun and the planets formed together, 4.6 billion years ago, from a cloud of gas and dust called the solar nebula. A shock wave from a nearby supernova explosion probably initiated the collapse of the solar nebula. The Sun formed in the center, and the planets formed in a thin disk orbiting around it.

A particular company charges advertisers a one-time cost of $ 500 $500dollar sign, 500, in addition to $ 4.50 $4.50dollar sign, 4, point, 50 for every one thousand times an advertisement is shown on the company's webpage. An advertiser wants its ad to appear M MM thousand times on the webpage, but does not want to spend more than $ 5 , 000 $5,000dollar sign, 5, comma, 000. Which of the following inequalities best describes the situation?
Answer:
500 + 4.50M is less than or equal to 5,000
Explanation:
$4.50 will be used every time an ad, M, will appear on a webpage. For example, if 3 ads were to appear on a webpage, we would use 4.50(3) to find the total cost of the advertisement. In addition, the company charges a one-time cost of $500, meaning that this number will not be multiplied into the inequality, since it is being added only once.
In addition, the advertiser does not want to spend more than $5,000, meaning that the cost should be less than $5,000.
Therefore, since we know that 4.50M gives us the cost of the advertisement, and $500 will be added as a "one-time cost," the best answer to this is 500+4.50M is less than or equal to 5,000.

An equation is formed of two equal expressions. The correct option is A.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The gas tank of each car has a volume of 16 gallons and the gas tank of each truck has a volume of 30 gallons. Therefore, the total gas needed for the fleet is,
16c + 30t
Also, it takes 2,000 gallons of gas to fill the empty gas tanks of the entire fleet. Therefore, the equation that shows the possible number of cars, c, and the number of trucks, t, in the fleet is,
16c + 30t =2000.
Hence, the correct option is A.

Imagine you are a systematist who has discovered an unfamiliar animal
A scientist who focuses on the naming and classification of species is a systematist, commonly referred to as a taxonomist. Their work entails classifying and categorizing species according to their genetic make-up, morphological traits, and evolutionary relationships.
As a systematist what to do after discovering an unfamiliar animal?An unfamiliar species has been found, and as a systematist, first course of action would be to carefully examine and record the animal's physical traits, behavior, habitat, and any other pertinent details that could assist me in determining its taxonomic classification.
In order to get their opinions and knowledge, then talk with colleagues and taxonomy specialists. Reaching out to experts on certain animal subspecies, such as mammal, bird, reptile, or insect researchers, may be one way to do this.
After that attempt to categorize the animal using recognized taxonomic systems using the information that had been at disposal. This could entail examining DNA samples, doing additional tests, contrasting its physical traits with those of known species, or some combination of these.
The work to record and publish the results in a scientific journal after determining the animal's taxonomic categorization and would also share this knowledge with other researchers in the field. This could increase our knowledge of biodiversity and have a significant impact on conservation initiatives meant to safeguard this recently discovered animal and its habitat.

A trapezoid is shown in the coordinate plane.
Which of the following gives the line or lines of symmetry about which the trapezoid can be reflected in order to map the trapezoid onto itself?
The line or lines of symmetry about which the trapezoid can be reflected in order to map the trapezoid onto itself is x = -2.
What is symmetry?Symmetry is defined as a likeness between two parts of an object that is equal and balanced. Planar symmetry, which refers to various types of symmetry on a flat surface, is illustrated by the four different types of symmetry.
A figure's symmetry line is the path it takes to transfer itself onto another figure. The midpoints of the parallel sides in the provided figure are (1, 4) and (-2, -2), and the trapezoid's symmetry line is at x = -2.
Thus, the line or lines of symmetry about which the trapezoid can be reflected in order to map the trapezoid onto itself is x = -2.

two objects, x and y, accelerate from rest with the same constant acceleration. object x accelerates for twice the time as object y. which of the following is true of these objects at the end of their respective periods of acceleration?
Answer:
X has travelled 4 times as far as Y
X is moving 2 times as fast as Y
Explanation:
Because x=1/2at²(get rid of the first portion of x=vt+1/2at² because initial v is 0 which multiplies to 0). If the acceleration is set to for example 10 (keep this constant for both X and Y) and we use t=1 and t=2 for time (as the time travelled of X is twice that of Y). Plugging this into the equation, at t=1, x=4. At t=2, x=20. 20 is four times greater than 5, so X has travelled 4 times as far as Y.
To find the difference in speed between the two objects, use the equation \(v_{f}=v_{0} +at\). Since the initial velocity is 0, that part can just be removed from the equation. With v=at, it is easy to see that if the time plugged in is twice for one than the other (and the acceleration is the same for both), the final result will be twice of the other as well. For example: If the acceleration is 10 again for both, then v=10t. If t is 1, the velocity is 10. If t is 2, the velocity is 20.
