Discrete mathematics. Write a (formal) proof of the following statement:"If 4 does not divide an integer n, then does not divide n² − 3n+ 5."

Here we have to prove if 4 doesn't divide an integer n, then 4 doesn't divide n2 -3n+5.

Answered: Write a (formal) proof of the following…

Smoking 2009, women and men In Exercise 2, we ex-amined the percentage of men aged 18–24 who smoked from 1965 to 2009 according to the Centers for DiseaseControl and Prevention. How about women? Here’s ascatterplot showing the corresponding percentages forboth men and women:a) In what ways are the trends in smoking behaviorsimilar for men and women?b) How do the smoking rates for women differ fromthose for men?c) Viewed alone, the trend for men may have seemed toviolate the Linearity Condition. How about the trendfor women? Does the consistency of the two patternsencourage you to think that a linear model for thetrend in men might be appropriate? (Note: there is nocorrect answer to this question; it is raised for you tothink about.)
Weight Gain of Athletes A researcher wishes to see whether there is any difference in the weight gains of athletes following one of three special diets. Athletes are randomly assigned to three groups and placed on the diet for 6 weeks. The weight gains (in pounds) are shown here. At a=0.005, can the researcher conclude that there is a difference in the diets? Diet A: 3, 4, 5, 6 Diet B: 12, 13, 14, 6, 7, 8 Diet C: 3, 4, 5 ,6 Part 2. State the hypotheses and identify the claim with the correct hypothesis. Part 3. Compute the test value. Always round score values to two decimal places. Part 4. Find the -value. Round the answer to four decimal places. Part 5. Reject or not to reject the null hypothesis.

Researchers are wondering whether they can predict college GPA with the number of hours studying per week. To test this, they randomly select 8 college students, record their GPA and the number of hours spent studying per week. ID GPA 1 2.5 2 2.7 3 3.4 4 3.7 5 2.7 6 1.9 7 2.0 8 4.0 Hours studying per week 25.0 Based on the information in the table above, the researchers compute the regression equation: Y = -0.970+ 0.125 X. Do the researchers have enough evidence to claim that the number of hours studying predicts students' GPA? Select the null hypothesis for the statistical test: b=0 OB=0 B = -0.970 Ob = 0.125 27.6 30.2 35.0 31.6 25.6 30.0 40.0

21 The Ebola virus has an infection rate of 11% per day as compared to the SARS virus, which has a rate of 4% per day. If there were one case of Ebola and 30 cases of SARS initially reported to authorities and cases are reported each day, which statement is true? At day 10 and day 53 there are more Ebola cases. (2) At day 10 and day 53 there are more SARS cases. (3) At day 10 there are more SARS cases, but at day 53 there are more Ebola cases. (4) At day 10 there are more Ebola cases, but at day 53 there are more SARS cases.
