What is the sum
of the rational expressions below?
Answer:
D. 4x² - x / x² - x - 2
Step-by-step explanation:
First cross multiply then sum the results:
cross:
x(x + 2) = x² + 2x
3x(x - 1) = 3x² - 3x
sum the results of the cross:
x² + 2x + 3x² - 3x
4x² - x (this goes at the top)
Then multiply the bottom:
(x - 1 )(x + 2)
x² + 2x - x - 2
x² - x - 2 (this stays at the bottom)

males in the netherlands are the tallest, on average, in the world with an average height of centimeters (cm) (bbc news website). assume that the height of men in the netherlands is normally distributed with a mean of cm and standard deviation of cm.
The probability that a Dutch male is taller than 195 cm is 0.2525
Out of a random sample of 1000 Dutch men, people taller than 190 cm are 253 in number using statistics.
Mean = 183 cm
SD = 10.5 cm
Z score = ( Value - Mean ) /SD
Dutch male is shorter than 175 cm
Z score = ( 175 - 183)/10.5 = -0.762
from z score table probability is 0.223
Dutch male is taller than 195 cm
Z score = ( 195 - 183)/10.5 = 1.143
from z score table probability is 0.8735 for shorter than 195 cm
Hence probability that a Dutch male is taller than 195 cm = 1 - 0.8735
= 0.1265
Dutch male is between 173 and 193 cm
Z score = ( 173 - 183)/10.5 = -0.952 => 0.1705Z score = ( 193 - 183)/10.5 = 0.952 => 0.8295

during a severe storm, electrical transformers that function independently are expected to operate 85 percent of the time. suppose 20 electrical transformers are randomly selected from the population. let the random variable t represent the number of electrical transformers operating during a severe storm. which of the following is the best interpretation of the random variable t ?
The binomial variable with mean 17 transformers and standard deviation √2.55 transformers.
In math standard deviation is defined as a measure of how dispersed the data is in relation to the mean.
Here we have know that the good electrical transformers operate at approximate 85% of the total time and 20 electrical transformers are chosen at random.
Here let us assuming the variable is a binomial variable.
Then we have written it as in the following form,
=> Mean = number of samples * probability
And the value of standard deviation is calculated as
=> Standard Deviation = √mean (1 − probability)
Here we know that the value of mean is calculated as,
=> 85% * 20 = 0.85*20 = 17 transformers
Then the value of Standard deviation is calculated as,
=> √mean * (1 − 0.85)
Apply the values on the formula, then we get,
=> √17 * 0.15 =√2.55 transformers.
Hence the random variable is a binomial variable.

The College Board reported that in 2014, the mean Math Level 2 SAT subject test score was 686 with a standard deviation of 96. Assuming scores follow a bell-shaped distribution; use the empirical rule to find the percent of students who scored less than 494.
Feedback: Incorrect. The z-score for this situation is (494 - 686) / 96 = -2. Recall that 95% of observations will fall within 2 standard deviations of mean. This means that 2.5% of observations will fall above 2 standard deviations and 2.5% of observations will fall below 2 standard deviations. This question asks for the percent of students who scored less than 494 (below 2 standard deviations). The correct answer is 2.5%.
Totally correct about the mentioned before is 2.5%. This is because the z-score for this situation is (494 - 686) / 96 = -2. According to the Empirical Rule, approximately 95% of observations will fall within 2 standard deviations of the mean. In this case, the question is asking for the percent of students who scored less than 494, which is below 2 standard deviations, so the answer is 2.5%.
SAT Math Level 2 ScoreThe Empirical Rule states that for a normal distribution, approximately 68% of the data will fall within one standard deviation of the mean, approximately 95% of the data will fall within two standard deviations of the mean, and approximately 99.7% of the data would get fall within 3 standard deviations of the mean. So if we know the mean and standard deviation of a normal distribution, we can use this rule to estimate the percentage of data that falls within a certain range.
In this specific question, the mean of Math Level 2 SAT subject test score was 686 with a standard deviation of 96. We were asked to find the percent of students who scored less than 494. To find this we first calculated the z-score which is (494 - 686) / 96 = -2.
Since the z-score is -2 it means that it's 2 standard deviation below the mean, and according to the Empirical rule 95% of observations will fall within 2 standard deviations of mean. This means that 2.5% of observations will fall above 2 standard deviations and 2.5% of observations will fall below 2 standard deviations. So the answer is 2.5%.

You measure the mass of a ring three times using the same balance and get slightly different values: 17.46 g, 17.42 g, 17.44 g
The variation in the values is due to random error. Hence, it can be reduced by taking more observations to estimate the measure of the mass of the ring.
One way to minimize experimental error in this situation is to take multiple measurements and use the average of those measurements as the final value. This helps to account for any small fluctuations or inaccuracies in the individual measurements.
Also, it is important to ensure that the balance is properly calibrated and that the ring is placed on the balance in the same way each time.
Other ways to minimize experimental error include using a more precise measuring instrument, such as a digital scale, and ensuring that the lab environment is controlled and stable (i.e. no drafts or vibrations that could affect the measurements).

Climbing Mt. Everest is not an easy task! Not only is it a difficult hike, but the Earth's atmosphere
decreases exponentially as you climb above the Earth's surface, and this makes it harder to breathe. The air
pressure at the Earth's surface (sea level) is approximately 14.7 pounds per square inch (or 14.7 psi). In
Denver, Colorado, elevation 5280 feet, the air pressure is approximately 12.15 psi.
a.) write an exponential equation
b.) what is the air press at the top of mount everest, elevation 29,000 feet?
The exponential equation that represents the relationship between the air pressure and the elevation above the Earth's surface is
y = 14.7 x 0.827^x
The air pressure at the top of Mount Everest, elevation 29,000 feet is approximately 1.931 psi
Finding exponential equation and calculating air pressureTo write an exponential equation for the relationship between the air pressure and the elevation above the Earth's surface, we can use the form y = a x b^x,
where y is the air pressure,
x is the elevation,
and a and b are constants.
We can use the data given in the problem to find the values of a and b.
Let y = air pressure (psi)
x = elevation (feet)
We know that at sea level (x = 0), y = 14.7 psi
At Denver, Colorado, elevation 5280 feet, y = 12.15 psi
We can use these two points to find the values of a and b in the equation y = a x b^x
12.15 = 14.7 x b^5280
b = (12.15/14.7)^(1/5280)
b = 0.827
a = 14.7
The exponential equation that represents the relationship between the air pressure and the elevation above the Earth's surface is
y = 14.7 x 0.827^x
b.) To find the air pressure at the top of Mount Everest, elevation 29,000 feet, we can substitute that value for x into the exponential equation.
y = 14.7 x 0.827^29000
y = 1.931 psi
The air pressure at the top of Mount Everest, elevation 29,000 feet is approximately 1.931 psi. It's worth noting that this is a very low air pressure and the human body is not able to survive with such low pressure without proper equipment.

What is the Pythagoras theorem?
The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.
We know that, measure of each angle in a rectangle is 90°.
Let the length of diagonal of rectangular pool be x
So using Pythagoras theorem, we get
x²=12²+7²
⇒ x²=144+49
⇒ x²=193
⇒ x=√193
⇒ x=13.89
≈13.9 meters
The measure of diagonal in a rectangular pool is 13.9 meters. Therefore, option A is the correct answer.

The vertices of the original triangle are given as follows:
A(-3,-2), B(-6,-5) and C(-1,-4).
The vertices of the reflected triangle are given as follows:
A'(4,2), B'(1,5) and C'(6,4).
Hence the composite rule is given as follows:
(x,y) -> (x + 7, -y).
Meaning that the glide reflection is defined as follows:
x -> x + 7: translation of 7 units right.y -> -y: reflection over the x-axis.More can be learned about glide reflections at brainly.com/question/5612016

Find the following for the given functions.
f(x): =
X/X + 9 ,
g(x) = x³
The results of operations between functions:
Case A: (f + g) (x) = x / (x + 9) + x³
Case B: (f - g) (x) = x / (x + 9) - x³
Case C: (f · g) (x) = x⁴ / (x + 9)
Case D: (f / g) (x) = 1 / [x² · (x + 9)]
Function (f / g) (x) has the following domain: x ∈ R - {- 9, 0}.
How to find the result of operations between two functions
According to function theory, we can obtain a function with more complexity by operations between two functions, the most common operations are listed below:
Addition: (f + g) (x) = f (x) + g (x)Subtraction: (f - g) (x) = f (x) - g (x)Multiplication: (f · g) (x) = f(x) · g(x)Division: (f / g) (x) = f (x) / g (x)Now we proceed to determine the resulting function:
Case A:
(f + g) (x) = f(x) + g(x)
(f + g) (x) = x / (x + 9) + x³
Case B:
(f - g) (x) = f(x) - g(x)
(f - g) (x) = x / (x + 9) - x³
Case C:
(f · g) (x) = f (x) · g (x)
(f · g) (x) = [x / (x + 9)] · x³
(f · g) (x) = x⁴ / (x + 9)
Case D:
(f / g) (x) = f(x) / g(x)
(f / g) (x) = [x / (x + 9)] / x³
(f / g) (x) = 1 / [x² · (x + 9)]
The domain of (f / g) (x) is the set of all values of x-values such that the function exists. In this case, we must determine the values of the denominator of (f / g) (x) such that it is not equal to zero.
x² · (x + 9) = 0
x = 0 or x = - 9
The domain of (f / g) (x) is: x ∈ R - {- 9, 0}.

The value of x that solves the equation is x = 28.10, and there are 4 eggs per batch.
Which value satisfies the equation?Particularly x is not in that equation, but we can write:
5x = 140.50
To solve for x, we need to divide both sides by 5, then we will get:
5x/5 = 140.50/5
x = 140.50/5
x = 28.10
How many eggs are needed per batch?To find this, we need to take the quotient between the number of eggs and the number of batches, so we will get:
12 eggs.
3 batches.
12/3 = 4
This means that you need 4 eggs per batch.
