Without referencing the book or the videos, review the following sales and cost data for LBCC Bike shop. Can you determine how many bikes you must sell each month in order to break even (net income of $0)? Make sure you defend your approach.

No one runs a business with the goal of only breaking even. How many bikes would you need to sell each month to earn $1,200 net income?

Lastly, you are considering a $2,000 advertising campaign that is expected to result in a one-time increase in sales of 15 bikes. Should you do it?

Hint: consider fixed versus variable costs.

A single stage double acting air compressor delivers 15 m3/min. measured at 1.013 bar and temperature 270C and delivers at 7 bar. The conditions at the end of the suction stroke are pressure 0.98 bar and temperature 400C. The clearance volume is 4% of the swept volume and the stroke / bore ratio is 1.3/1, compressor runs at 992 rpm. Calculate the volumetric efficiency, cylinder dimensions, indicated power and isothermal efficiency of this compressor. Take the index of compression and expansion as 1.3, R= 0.587kJ/Kg-K.

Write regular expressions that describes the following language:

The language over {0,1,/} that contains all and only the strings that are base-2 (as above, you can use base-10 if you prefer) representations of rational numbers. Define a representation of a rational number to be either a representation of an integer, or two representations of integers separated by “/”. Leading 0s are allowed this time.

Hello. Please answer the following two-part question in Scheme. Not Python, not any form of C, but in the language Scheme. If you do not know Scheme, please do not answer the question. I've had to upload it multiple times now. Thank you.

3.1 Write a recursive function called split that takes a list and returns a list containing two lists, each of which has roughly half the items in the original list. The easiest way to do this is to alternate items between the two lists, so that (split '(1 2 3 4 5)) would return '((1 3 5) (2 4)). I recommend using two base cases: one for an empty list and the other for a list containing one item.
> (split '())

(() ())

> (split '(3))

((3) ())

> (split '(4 8))

((4) (8))

> (split '(8 6 7 5 3 0 9))

((8 7 3 9) (6 5 0))

3.2 Write a recursive function called merge that takes two sorted lists of numbers and merges them together into one sorted list containing all of the number in both lists including duplicates.
> (merge '() '())

()

> (merge '() '(1 2 3))

(1 2 3)

> (merge '(1 2 3) '())

(1 2 3)

> (merge '(2 4 7) '(1 3 5))

(1 2 3 4 5 7)

Use SPSS to get the appropriate output. Along with providing the SPSS output, use the 5 steps of hypothesis testing to analyze the results by using the p-value approach.

4. Workers went through a training program to help them in the packaging of items needed for the purchaser to assemble a toy. The number of defective packages returned per month is recorded for each employee doing the packaging. Below are the before and after number of defects per month per employee. Test to see if the mean difference in defects has lowered after the employees went through the training program. Test at the 0.01 level of significance.

Given below is a bivariate distribution for the random variables x and y.

(c)

Using the result of part (b), compute

E(x + y)

and

Var(x + y).

E(x + y)

=

Var(x + y)

=

(d)

Compute the covariance and correlation for x and y. (Round your answer for correlation to two decimal places.)

covariancecorrelation

Are x and y positively related, negatively related, or unrelated?

The random variables x and y are  ---Select--- positively related negatively related unrelated .

(e)

Is the variance of the sum of x and y bigger, smaller, or the same as the sum of the individual variances? Why?

The variance of the sum of x and y is  ---Select--- greater than  less than unrelated the sum of the variances by two times the covariance, which occurs whenever two random variables are  ---Select--- positively related negatively related unrelated .

A chessboard pattern is a pattern that satisfies the following conditions:

• The pattern has a rectangular shape.
• The pattern contains only the characters '.' (a dot) and 'X' (an uppercase letter X).
• No two symbols that are horizontally or vertically adjacent are the same.
• The symbol in the lower left corner of the pattern is '.' (a dot).

You are given two numbers. N is a number of rows and M is a number of columns. Write a program that generates the chessboard pattern with these dimensions, and outputs it.

Input
The first line contains two numbers N and M (1 ≤ N ≤ 50, 1 ≤ M ≤ 50) separated by a whitespace.

Output
Output should contain N lines each containing M symbols that correspond to the generated pattern. Specifically, the first character of the last row of the output represents the lower left corner (see example 1).

example:

input:

8 8

output:

X.X.X.X.
.X.X.X.X
X.X.X.X.
.X.X.X.X
X.X.X.X.
.X.X.X.X
