evaluate f(-x)=x/x2+1
To evaluate f(-x) when f(x) = x/(x^2 + 1), we need to substitute -x for x in the function.
So f(-x) = (-x)/((-x)^2 + 1)
Simplifying the denominator we get:
f(-x) = (-x)/(x^2 + 1)
The function f(-x) is equivalent to the function f(x) with the x-value negated. The value of the function f(-x) is the same as the value of the function f(x) but with the x-value negated.
It's important to note that we can also express this as f(-x) = -f(x)
So the value of f(-x) is x/(x^2 + 1) with the x-value negated.

The distance covered on the triangular path to home along point A to B to C is 23.42 miles.
What is Pythagorean theorem?In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem. These triangle's three sides are known as the Perpendicular, Base, and Hypotenuse. Due to its position opposite the 90° angle, the hypotenuse in this case is the longest side. When the positive integer sides of a right triangle (let's say sides a, b, and c) are squared, the result is an equation known as a Pythagorean triple.
Given that the trip to home goes from point A to point B and then to point C.
The path traced thus, represents the hypotenuse of the two triangles. Triangle BHA and triangle BCH.
The Pythagorean theorem is given as follows:
a^2 + b^2 = c^2
For triangle BHA substitute the value of a = 4 and b =6.
4^2 + 6^2 = c^2
16 + 36 = c^2
c = 7.21
For triangle BHC, substitute the value of a = 7 and b =6.
7^2 + 6^2 = c^2
49 + 36 = c^2
c = 9.21
Now, from point B to point H the additional distance is 7 miles, hence the total distance traveled is:
D = 7.21 + 9.21 + 7
D = 23.42
Hence, the distance covered on the triangular path to home along point A to B to C is 23.42 miles.

A 10 foot vertical post cast a 2 foot shadow at the same time a nearby cellphone tower cast a 116 foot shadow. How tall is the cell phone
Answer:23.2
Step-by-step explanation:
10/2=5
10/5=2
116/5=23.2
Answer:
580 ft.
Step-by-step explanation:
The height of the cellphone tower can be found using the following proportion:
(shadow of cellphone tower) / (shadow of 10 foot post) = (height of cellphone tower) / (10 feet)
Solving for the height of the cellphone tower:
(116 feet) / (2 feet) = (height of cellphone tower) / (10 feet)
Which brings us to:
116 ÷ 2 = x ÷ 10
58 = x ÷ 10
580 = x
The cell phone tower is 580 ft.

Consumer Reports gave a report about the life (hours) of size AA batteries in toys. A total of 16 random toys were tested which gave a mean life of 3.58 hours with sample standard deviation of 1.85 hours. a. The packaging for the batteries claims that the AA batteries last around 5 hours in toys. Does the sample differ from the claim? a = .05 b. Would your answer change if a - .001? Explain.
a. To determine if the sample differs from the claim, we can use a hypothesis test. The null hypothesis is that the mean life of the AA batteries in toys is 5 hours, and the alternative hypothesis is that the mean life is different from 5 hours.
What does a math equation mean?
The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.
Using a t-test with a significance level of 0.05, we can calculate the t-statistic and the p-value.
The t-statistic is calculated as (mean - hypothesized mean) / (standard deviation / sqrt(sample size))
t = (3.58 - 5) / (1.85 / sqrt(16)) = -2.06
The p-value is the probability of getting a t-statistic as extreme or more extreme than the one we calculated, assuming the null hypothesis is true.
p-value = P(t < -2.06) = 0.048
Since the p-value is less than 0.05, we can reject the null hypothesis and conclude that the sample mean of 3.58 hours differs significantly from the claim of 5 hours.
b. The p-value is the probability of getting a t-statistic as extreme or more extreme than the one we calculated, assuming the null hypothesis is true. If we change the significance level to 0.001, the p-value would be less than 0.001, which would still be less than the new significance level. Therefore the conclusion would still be the same, the sample mean of 3.58 hours differs significantly from the claim of 5 hours.
However, it's worth mentioning that a lower significance level (0.001) would require a stronger evidence against the null hypothesis, therefore it would be more stringent in accepting the alternative hypothesis.

The mean of the sampling distribution is related to the mean of the population, the standard deviation of the sampling distribution is related to the standard deviation of the population and the shape of the sampling distribution is affected by the sample size.
a. The mean of the sampling distribution is related to the mean of the population. The mean of the sampling distribution is an estimate of the population mean and is usually denoted by x⁻. The mean of the sampling distribution is expected to be close to the population mean, as the sample size increases. However, if the sample size is small, there will be more variation in the sample means and the sample mean will not be an accurate estimate of the population mean.
b. The standard deviation of the sampling distribution is related to the standard deviation of the population. The standard deviation of the sampling distribution is an estimate of the population standard deviation and is usually denoted by s. The standard deviation of the sampling distribution is expected to be smaller than the population standard deviation, as the sample size increases. The standard deviation of the sampling distribution is also affected by the sample size, it decreases as sample size increases.
c. The shape of the sampling distribution is affected by the sample size. As the sample size increases, the shape of the sampling distribution becomes more normal and less skewed, regardless of the shape of the population. The larger the sample size, the less spread in the sample means and more likely that the sample mean will be close to the population mean.

What is linear equation?An algebraic equation with simply a constant and a first-order (linear) term, such as y=mx+b, where m is the slope and b is the y-intercept, is known as a linear equation. The variables in the previous sentence, y and x, are referred to as a "linear equation with two variables" at times. Ax+By=C represents a two-variable linear equation in its standard form. As an illustration, the conventional form of the linear equation 2x+3y=5 It is rather simple to locate both intercepts when an equation is stated in this way (x and y).
We can write these values as coordinate points, on the form:
As a result, the sentence: "After an hour of driving, Katie had $6.75 worth of gas." can be seen as the following:
(1,6.75)
And: "After 6 hours of driving, there was only 1.5 gallons left" will have the point:
(6,1.5)$
Part B
With this in mind, we can find the slope of a linear function that passes through those two points. Then,
[tex]$m=\frac{y_2-y_1}{x_2-x_1}=\frac{1.5-6.75}{6-1}=\frac{-5.25}{5}=-1.05$[/tex]
Thus, the slope is -1.05.
Part C
Now, we will write a linear equation that relates[tex]$\mathrm{g}$[/tex] and[tex]$\mathrm{h}$[/tex]. As we already have the slope, we can use it to find the y-intercept as:
[tex]$$y=m x+b$$[/tex]
[tex]$g=m h+b$[/tex]Writing it with the variable[tex]s $\mathrm{g}$[/tex]and [tex]$\mathrm{h}$[/tex].
[tex]$$1.5=(-1.05)(6)+b$$[/tex]
[tex]1.5+6.3=b \\[/tex]
7.8=b
This means that an equation for g in terms of h is given by:
[tex]$$g=-1.05 h+7.8$$[/tex]
Part D
For this portion, we will apply the linear equation we discovered for calculating how much gas she will still have after a three-hour drive. Thus, h will have a value of 3, and we replace on the function to get the following result:
[tex]g=-1.05(3)+7.8 \\[/tex]
=-3.15+7.8
=4.65
This means that Katie will have 4.65 gallons left after driving for 3 hours.
The complete question is,

The probability of exactly 4 of the 7 hens contracting the disease is ⁷C₄(0.15)⁴(0.85)³.. The ideal response is (A).
How can the binomial distribution be used to calculate probability?
The binomial theorem, which can be expressed as (a + b)n = nC0anb0 + nC1an1b1 + nC2an2b2 +....+ nCna0bn, is the foundation of the binomial distribution.Events must be independent of one another and have probabilities that add up to 1 in order for the probability to be used.
Due to that,There is a 15% chance that the chicken will be affected it is spelled as as,
15% P(infected)
= 15/100
= 0.15
Consequently, the likelihood of avoiding diseased chicken is,
P(not contaminated) = 1 - 0.15= 0.85
Seven chickens in all will be used for the test.
Now, the binomial distribution may be used to determine the likelihood of having exactly 4 sick chickens.
nCxpxqnx is a general expression for the binomial distribution.
n = 7 and x = 4 for the case where p = P(infected) and q = P(not infected) are given
Consequently, the likelihood is given as,
P = 7C4(0.15)4(0.85)3 (Exact 4 are infected).

A binomial distribution should be utilized since the answer—whether or not an employed person commutes more than 10 minutes to work—is a yes or no question.
B. The answer is the percentage of days a week on which a working person travels more than 10 minutes to go to work. The Poisson distribution should be utilized since the number of days is a count variable and the mean number of days does not always equal the variance.
C. The answer is the number of minutes a student studies each week. Since the number of study minutes is a continuous variable with an equal mean and variance, the normal distribution should be applied.
D. The answer is the subject's blood type (A,B,AB, or O). Given that there are four alternative outcomes for blood type, multinomial distribution should be employed.

jim holzman at ace ticket has a few premium seats in the front row. he would like to find out how much extra he can charge for those tickets, relative to identical seats right behind in the second row. to do so, he decided to run a survey.
The price difference, which can then be used to determine the extra he can charge for the front row tickets.
To calculate the price difference between the front row and second row tickets, Jim should first identify the mean price of the second row tickets, P2. He can then compare the mean price of the second row tickets to the mean price of the front row tickets, P1. He can then calculate the price difference between the two rows by subtracting the mean price of the second row tickets from the mean price of the first row tickets, (P1-P2). This will give him the price difference, which can then be used to determine the extra he can charge for the front row tickets.
For example, if the mean price of the second row tickets, P2, is $15 and the mean price of the first row tickets, P1, is $20, then the price difference would be $5, meaning he can charge an extra $5 for the front row tickets.
Formula: Price Difference = P1 - P2

The equation of the tangent line to the given curve at the point (1, 5) is y = 15x – 10.
The given function is f(x) = 6x2 - x3.
We need to find the equation of the tangent line to the given curve at the point (1, 5).
To find the equation of the tangent line, we need to find the slope of the tangent line. The slope of the tangent line is given by the derivative of the curve at the given point.
The derivative of the given curve is f' (x) = 3x2 + 12x.
Substituting the value of x as 1, we get the slope of the tangent line at (1, 5) as f' (1) = 3(1)2 + 12(1) = 15.
Therefore, the equation of the tangent line at (1, 5) is given by y – 5 = 15(x – 1).
This can be simplified to y = 15x – 10.

Directions: solve for x round to the nearest tenth
To solve for x in this problem, we need to use the Law of Cosines.
Solve for x round to the nearest tenth?This law states that in any triangle, the sum of the squares of the lengths of the two sides is equal to the square of the length of the third side.In this case, we have two sides, AB and BC, and we need to find the measure of angle A.We can set up the equation as follows:
a² = b² + c² - 2bc cos(x)
We can substitute the values for a, b, and c, which are 22, 10, and 10 respectively. This gives us the equation:
22² = 10² + 10² - 2(10)(10) cos(x)
Simplifying the equation gives us:
484 = 200 - 200cos(x)
Therefore,
200cos(x) = 284
We can divide both sides by 200 to get cos(x) = 1.42.
We can take the inverse cosine of both sides to get x = 54.15°.
Rounding to the nearest tenth, x = 54.
