For any n ≥ 1 let Kn,n be the complete bipartite graph (V, E) where V = {xi : 1 ≤ i ≤ n} ∪ {yi : 1 ≤ i ≤ n} E = {{xi , yj} : 1 ≤ i ≤ n, 1 ≤ j ≤ n} (a) Prove that Kn,n is connected for all n ≤ 1. (b) For any n ≥ 3 find two subsets of edges E 0 ⊆ E and E 00 ⊆ E such that (V, E0 ) and (V, E00) are spanning trees which are not isomorphic.

Assume you are carrying out the titration of 50 mL of a 0.025 M solution of acetic acid with 0.1023 MNaOH. Acetic acid has aKaof 1.8×10−5.
(a) Calculate the pH of the solution at V= 0, V= 0.3Veq, V=Veq, and V= 1.2Veq. (Veq is the equivalence point volume)
(b) If a phenolphthalein indicator was used in this titration, where would the apparent endpoint occur? Assume the apparent endpoint would occur at the end of the color range of the indicator (pH’s of 8.0-9.6).

Yeast make alcohol in the absence of oxygen by a process called fermentation (i.e., anaerobic respiration). Complete fermentation of one of the sugar glucose (C6 H12 O6) will generate two moles of ethanol (C2 H6 O), two moles of carbon dioxide (CO2) gas, and tow moles of the important molecule ATP (C10 H16 N5 O13 P3), using in cellular transfers. You perform an experiment to make alcohol, so you set up an anaerobic fermentation system using yeast. You add 135 grams of glucose to your system and allow the sugar to be fermented to completion, trapping all fermentation products. (a) How many molecules of ATP were produced in your experiment? What is the total mass of the ATP. (b) The volume of the fermenation tank was 15 Liters, and the temperature was kept constant during the experiment at 25 0C. Is it possible to determine the final tank pressure of the CO2 gas produced by this experiment? Will the Ideal Gas Law work here? (c) What was the total volume of ethanol produced in this experiment? The density of ethanol is 0.789g/mL.

if the mean=m,variance= v, observed value=o
we have four groups, g1 age 18-28,the observed resposibility of accident=127,m=0.809,v=0.848
for the same group the observed (not responsible) of accidents=192,m=1.22,v=1.849

1-for the data shown which type of test we must use and why
2- using the test find the expected value for all responsible and not responsible accidents participations
3-if the test used is kai square find using (ovserved-expected)^2/expexted for all the data groups( resposible and not)
4- give an explanation or interpret the statistical test results for the significant values after finding p-value for the test
