A polynomial expression must adhere to certain rules. Anything that falls outside of these guidelines is not considered a polynomial, no matter how closely it resembles one.

How to explain the expression

Take for instance the first expression: 7j² -6j + 5k - 13. Though this may appear as a polynomial at first glance, j, the variable present within, is raised to an exponent deemed unacceptable by definition; (i.e., its exponent raises j to 2/1, which is non-integer notation).

The second expression, also violates this same standard since "x-2" indicates x being raised to the negative second power -- a numerical representation contrary to the stipulation. .

Alex has 10 different kinds of lunch meat and 9 different kinds of cheese. If he wants to make a sandwich with one kind of meat and two kinds of cheese, how many different sandwiches could he make

Answers

Alex can make a total of 180 different sandwiches by choosing one kind of meat from 10 options and two kinds of cheese from 9 options.

To determine the number of different sandwiches Alex can make, we need to consider the combinations of meat and cheese. Since Alex can choose one kind of meat from 10 options, there are 10 choices for the meat component of the sandwich. For the cheese component, Alex can choose two kinds of cheese from 9 options.

To calculate the total number of combinations, we can use the formula for combinations without repetition. The formula is nCr = n! / (r!(n-r)!), where n is the total number of options and r is the number of choices. In this case, n is 9 (number of cheese options) and r is 2 (number of cheese choices). Thus, the number of combinations of two kinds of cheese is \(9C2\)= 9! / (2!(9-2)!) = 36.

Find the domain for the rational function f(x) = x-5/2x-3

Answers

Answer:

the domain of f(x) is set of all real numbers except 3/2

Step-by-step explanation:

Since the denominator cannot equal 0,  2x - 3 ≠ 0

                                                                        2x ≠ 3

                                                                          x ≠ 3/2

Any real number can replace x in the numerator.  

So, the domain of f(x) is all real numbers except 3/2

The domain of the given function is required.

The domain is (-∞,3/2),(3/2,∞)

Domain of a function

The given function is \(f(x)=\dfrac{x-5}{2x-3}\)

The domain of a function are the values of x for which the given function is defined.

The function is undefined when \(x=\dfrac{3}{2}\)

\(f(3/2)=\dfrac{\dfrac{3}{2}-5}{2\times \dfrac{3}{2}-3}=\infty\)

So, \(x\neq \dfrac{3}{2}\)

The domain is \(\left(-\infty,\dfrac{3}{2}\right),\left(\dfrac{3}{2},\infty\right)\)

5.3. From the data given in Table 2.6 on earnings and education, we obtained the following regression [see Eq. (3.7.3)]: Meanwage = 0.7437 + 0.6416 Education; se = (0.8355) ( ) t = ( ) (9.6536) r2 = 0.8944 n = 13 a) Fill in the missing number 2) how do you interpret the coefficient 0.6416 c. would you reject the hypothesis that educationhas no affected whatsoever on wages?

Answers

a) The missing number in Meanwage = 0.7437 + 0.6416 Education; se = (0.8355) ( ) t = ( ) (9.6536) r2 = 0.8944 n = 13 is se ≈ 0.0664. b. The mean wage is expected to increase by 0.6416 units. c. we would reject the null hypothesis, suggesting that education does indeed have a significant effect on wages.

a) From the information given, we can see that the standard error (se) and t-value are missing for the Education coefficient (0.6416). To find the missing standard error, we can use the t-value formula:

t = (coefficient - 0) / standard error

Rearranging the formula:

standard error = (coefficient - 0) / t

Since we have the t-value for Education (9.6536):

se = 0.6416 / 9.6536 ≈ 0.0664

b) The coefficient of 0.6416 for Education can be interpreted as follows: for each additional year of education, the mean wage is expected to increase by 0.6416 units, keeping all other factors constant.

c) To test the hypothesis that education has no effect on wages, we can use the t-value. The null hypothesis (H0) states that the coefficient of Education is 0 (meaning no effect). In this case, the t-value is 9.6536, which is significantly large. With a high t-value and a low standard error (0.0664), we have strong evidence to reject the null hypothesis, suggesting that education does indeed have a significant effect on wages.

an experimenter surveyed two acres of a desert preserve and found six cactus wren nests. assuming that the habitat is fairly uniform, how many nests would he expect to be in the entire 200-acre preserve?

Answers

600 cactus wren nests the experimenter would expect to be in the entire 200-acre preserve.

To estimate the number of cactus wren nests in the entire 200-acre preserve, we can use the ratio of the area surveyed to the number of nests found.

Let's call the number of nests in the entire 200-acre preserve "N".

The ratio of the area surveyed to the number of nests found is:

2 acres / 6 nests = 200 acres / N nests

We can use this ratio to find the number of nests in the entire 200-acre preserve:

N nests = 200 acres * (6 nests / 2 acres)

N nests = 200 * 3

N nests = 600

So the experimenter would expect to find approximately 600 cactus wren nests in the entire 200-acre preserve, assuming that the habitat is fairly uniform.

as x approaches infinity, for which function does f(x) approach negative infinity? select all that apply.

Answers

Both \(f(x) = -x^2\) and \(f(x) = -2x^3 + 5x^2 - 3x + 7\) approach negative infinity as x approaches infinity.

As x approaches infinity, the dominant term of the function determines its behavior. In the case of \(f(x) = -x^2\), the term \(x^2\) becomes infinitely large and negative, causing the entire function to approach negative infinity. Similarly, in the case of \(f(x) = -2x^3 + 5x^2 - 3x + 7\), the term \(-2x^3\) dominates and becomes infinitely negative as x approaches infinity, causing the entire function to approach negative infinity. This is because the negative exponent on \(x^3\) causes the value of the term to become increasingly negative as x increases without bound.

A scientist inoculates mice, one at a time, with a disease germ until he finds 2 that have contracted the disease. If the probability of contracting the disease is 1/11, what is the probability that 7 mice are required?

Answers

The probability that 7 mice are required to find 2 that have contracted the disease is 0.0002837 or approximately 0.028%.

The probability of contracting the disease is 1/11 for each mouse inoculated. Therefore, the probability that 2 mice will contract the disease in a row is (1/11) x (1/11) = 1/121.

To find the probability that 7 mice are required, we need to use the concept of binomial distribution.

The probability of getting 2 successful outcomes (i.e., mice that contract the disease) in 7 trials (i.e., inoculations) can be calculated using the binomial formula: P(2 successes in 7 trials) = (7 choose 2) x (1/121)^2 x (120/121)^5 = 21 x 1/14641 x 2482515744/1305167425 = 21 x 0.0000069 x 1.9037 = 0.0002837 or approximately 0.028%.

a property owner paid $25 per front foot for a lot 600 ft. x 1,452 ft. how many acres were in the lot that he bought?

Answers

A property owner paid $25 per front foot for a lot 600 ft. x 1,452 ft,  The lot size is 600 ft. x 1,452 ft., which is equivalent to approximately 20 acres.

To determine the number of acres in the lot, we need to convert the dimensions from feet to acres.

The lot has a length of 600 ft and a width of 1,452 ft. To convert these dimensions to acres, we divide each dimension by the number of feet in an acre, which is 43,560.

Length in acres = 600 ft / 43,560 ft/acre

Width in acres = 1,452 ft / 43,560 ft/acre

Now, we can calculate the total area of the lot in acres by multiplying the length and width in acres:

Total area = Length in acres * Width in acres

After performing the calculations, the total area of the lot is obtained. The final answer represents the number of acres in the lot.

Please note that since the final answer is a numerical value, it can be provided directly without the need for an explanation.

Answers

To construct a box plot from the given data, which represents the diameters of cans in an assembly line, we need to determine the five-number summary and plot the corresponding box and whisker plot.

The five-number summary consists of the minimum value, the first quartile (Q1), the median (Q2), the third quartile (Q3), and the maximum value.

To construct the box plot, we start by arranging the data in ascending order: 5.1, 5.2, 5.2, 5.2, 5.3, 5.5, 5.5, 5.5, and 5.6. The minimum value is 5.1, and the maximum value is 5.6. The median is the middle value, which in this case is 5.3.

To find the first quartile (Q1) and the third quartile (Q3), we divide the data into two halves. Q1 is the median of the lower half, which consists of 5.1, 5.2, 5.2, and 5.2. Q3 is the median of the upper half, which consists of 5.5, 5.5, 5.5, and 5.6. The box plot will show the minimum value, Q1, Q2 (median), Q3, and the maximum value, giving us a visual representation of the distribution and variability of the data.
