Answer:
$18.59
Step-by-step explanation:
Tax:
15.80 x .045 = .711
Cost after tax:
15.80 +.711 = 16.511
Tip:
16.511 x .15 = 2.47665
Total cost
16.511 + 2.47665 = 18.58665 Rounded to the nearest penny is $18.59

Jeri bought 32 cookies and 56 slices of pizza for his sisters birthday. Each guest will receive the same number of cookies and pizza, with nothing left over. If Jeri wants to invite the greatest number of guests, how many cookies will each guest receive?
Reason:
32 = 8*4
56 = 8*7
We see that 8 is the largest common factor, aka GCF, of 32 and 56
So this is the greatest number of guests possible.
Each guest will get 32/8 = 4 cookies and 56/8 = 7 slices of pizza.

(Use a comma to separate answers as needed.)
A. The set of numbers is {}
B. The set of numbers is {x|XEN and x> }}
C. The set of numbers is {x|XEN and x< }
D. The set of number is {xXEN and x =}
The set of numbers is S = { x ∈ N ; x > 22 }.
We have the statement:
Set of natural numbers greater than 22.
We need to make the set from it.
A set is a collection of different things objects or elements that are used to represent a situation or a function in a concise form.
For example a set of real numbers can be denoted by x ∈ R.
There can be finite or infinite sets. In finite sets, the number of elements are limited whereas in infinite sets it is not limited.
Here, the set that will be formed can be written as:
S = { x ∈ N ; x > 22 }
Therefore, the set of numbers is S = { x ∈ N ; x > 22 }.

Assuming that A equals 4 points, B equals 3 points, C equals 2 points, D equals 1 point, and F is worth no points, determine 's grade-point average for the semester.
The second semester grade point average for Patty was 2.21.
Due to that,
She received an upper D mark in the five hours of discrete math.
A higher B in her three-hour sociology class,
In her one-hour engineering course, she received an upper C.
And an upper B mark in her five-hour philosophy course.
A is worth four points, B is worth three, C is worth two, D is worth one, and F is worth none.
We must discover,
The semester's grade point average for Patty.
The answer to the query is
The student's grade point average is:
multiplying each point by its corresponding credit hour, adding them all up, and then dividing the result by the total amount of credit hours.
Then,
A single point is equal to 5(1) + 3(3) + 1(2) + 5(3), which is 5 + 9 + 2 + 15 = 31.
The numbers outside of the parentheses represent the credit hours while those inside represent the points.

The amount taken from Jim's check for FICA taxes is $75.51.
What are FICA taxes?FICA (Federal Insurance Contributions Act) taxes are of two types: Social Security tax and Medicare tax.
FICA taxes simply mean United States federal payroll (or employment) taxes imposed on both employees and employers. The purpose of FICA taxes is to fund Social Security and Medicare.
These two federal programs benefit retirees, the disabled, and the children of deceased workers.
The rate for the Social Security tax is 6.2% of the taxpayer's gross pay.
The rate for the Medicare tax is 1.45% of the income earner's gross pay.
The FICA taxes rate is 7.65%.
Data and Calculations:Gross pay for the week = $987
FICA taxes = 7.65%
FICA taxes in dollars = $75.51 ($987 x 7.65%)

For some linear relationships, doubling the independent variable results in doubling the function value. For example, doubling the number of steps in a staircase doubles the height of the staircase. Does this doubling property hold for every linear relationship?
Using linear function concepts, it is found that this doubling property does not hold for every linear relationship.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.One example of function is:
y = 4x + 3.
When x = 1:
y = 4 + 3 = 7.
When x = 2:
y = 8 + 3 = 11.
The input did not double, meaning that this doubling property does not hold for every linear relationship, it doubles only for a linear function with a slope of 2 and intercept of 0.

In general, [tex] \rm a_k = \frac{ log_{(k + 1) ^{(2k - 1)} } ((k + 2 {)}^{2k}) }{log_{(k + 2) ^{(2k - 1)} } ((k + 1 {)}^{ {k}^{2} })} [/tex]
Let [tex] \rm P_n = \frac{ log_{ {(n + 1)}^{(2n - 1)} }( {2}^{2n} ) }{ log_{ {2}^{(2n - 1)} }((n + 1) {}^{ {n}^{2} } )} \cdot \prod \limits_{k = 1}^{n - 1} a_k[/tex] for integer n [tex]\geq [/tex] 2.

Use the change-of-base identity and the exponent property for logarithms.
[tex]\log_b(a) = \dfrac{\log_c(a)}{\log_c(b)} \implies \log_b(a) = \dfrac1{\log_a(b)}[/tex]
[tex]\log_c(a^b) = b \log_c(a)[/tex]
This lets us rewrite
[tex]\log_{(k+1)^{2k-1}} (k+2)^{2k} = \dfrac{2k}{\log_{k+2}(k+1)^{2k-1}} = \dfrac{2k}{(2k-1) \log_{k+2}(k+1)}[/tex]
[tex]\log_{(k+2)^{2k-1}} (k+1)^{k^2} = \dfrac{k^2}{\log_{k+1} (k+2)^{2k-1}} = \dfrac{k^2}{(2k-1) \log_{k+1}(k+2)}[/tex]
It follows that
[tex]a_k = \dfrac2k \dfrac{\log_{k+2}(k+1)}{\log_{k+1}(k+2)} = \dfrac2k \left(\ln^2(k+1)}{\ln^2(k+2)}[/tex]
so that the product of [tex]a_k[/tex] telescopes:

We can similar reduce the coefficient of [tex]P_n[/tex] to write
[tex]\log_{(n+1)^{2n-1}}(2^{2n}) = \dfrac{2n}{(2n-1) \log_2(n+1)}[/tex]
[tex]\log_{2^{2n-1}}(n+1)^{n^2} = \dfrac{n^2}{(2n-1)\log_{n+1}(2)}[/tex]
[tex]\implies \dfrac{\log_{(n+1)^{2n-1}}(2^{2n})}{\log_{2^{2n-1}}(n+1)^{n^2}} = \dfrac2n \dfrac{\ln^2(2)}{\ln^2(n+1)}[/tex]
Then the expression for [tex]P_n[/tex] reduces significantly to
[tex]P_n = \dfrac2n \dfrac{\ln^2(2)}{\ln^2(n+1)} \cdot \dfrac{2^{n-1}}{(n-1)!} \dfrac{\ln^2(n+1)}{\ln^2(2)} = \dfrac{2^n}{n!}[/tex]
and we ultimately find
[tex]\displaystyle \sum_{n=2}^\infty P_n = \sum_{n=0}^\infty \frac{2^n}{n!} - \frac{2^1}{1!} - \frac{2^0}{0!} = \boxed{e^2 - 3}[/tex]

What are some examples of geometric series?
In mathematics, a geometric series is an infinite series with the formula a + ar + ar2 + ar3 +, where r is referred to as the common ratio. The geometric series for a = 1 and r = 1/2, or 1 + 1/2 + 1/4 + 1/8 +, is a straightforward illustration and converges to a sum of 2. (or 1 if the first term is excluded).We are given to find the values of a₁ and r of the following geometric series
2 - 2 + 2 - 2 + 2 - ........
We know that
a₁ is the first term and r is the common ratio of the given geometric series.
We can see that the first term of the given geometric series is 2.
So. we must have
a₁ = 2
Also, common ratio is found by dividing a term by its preceding term.
Therefore, the common ratio r of the given geometric series is
r = -2/2 = 2 / -2 = ...... = -1
Thus, for the given geometric series, the first term is a₁ = 2 and the common ratio is r = -1.

Apple weights in an orchard are normally distributed. From a sample farmer Fred determines the mean weight of a box of apples to be 270 oz. with a standard deviation of 10 oz. He wonders what percent of the apple boxes he has grouped for sale will have a weight less than 255 oz.
Carl calculates the z-score corresponding to the weight 255oz= -1.5.
Now, Carl decides to find the percent associated with boxes less then 255 oz, so he rounds to hundred and substract 50% - 7% = 43%.
Given that,
In an orchard, apple weights are typically distributed. Fred the farmer concludes from a sample that the average weight of a box of apples is 270 ounces, with a standard deviation of 10 ounces.
He is interested in knowing what proportion of the apple boxes he has gathered for sale will weigh less than 255 oz.
Mean is 270
Standard deviation is 10
x = 255
Formula for z-score,
z = (x - mean)/SD
z = (255 - 270) / 10
=> z = -15 / 10
=> z = -1.5
Hence, by using z-table,
-1.5 equates to 0.0668, which suggests that 0.07
Therefore, 7% of Apple boxes weigh less than 255 oz.
The ratio of boxes is between 255 oz and 270 oz,
Calculating the proportion
Now,
50% - 7% = 43%.
Therefore, Carl calculates the z-score corresponding to the weight 255oz= -1.5.
Carl decides to find the percent associated with boxes less then 255 oz, so he rounds to hundred and substract 50% - 7% = 43%.
