The local bakery bakes more than a thousand 1-pound loaves of bread daily, and the weights of these loaves varies. The mean weight is 1.7 lb. and 3 oz., or 856 grams. Assume the standard deviation of the weights is 25 grams and a sample of 32 loaves is to be randomly selected.
(A) This sample of 32 has a mean value of x, which belongs to a sampling distribution. Find the shape of this sampling distribution.
a) skewed right
b) approximately normal
c) skewed left
d) chi-square
(b) Find the mean of this sampling distribution. (Give your answer
correct to nearest whole number.)
_____ grams
(c) Find the standard error of this sampling distribution. (Give
your answer correct to two decimal places.) ______
(d) What is the probability that this sample mean will be between
846 and 866? (Give your answer correct to four decimal places.)
_______
(e) What is the probability that the sample mean will have a value
less than 847? (Give your answer correct to four decimal places.)
_______
(f) What is the probability that the sample mean will be within 4
grams of the mean? (Give your answer correct to four decimal
places.) _______

± Percent Ionization In addition to the acid-dissociation constant, Ka, another measure of the strength of an acid is percent ionization, determined by the following formula:Percent ionization=[HA] ionized[HA] initial×100% Percent ionization increases with increasing Ka. Strong acids, for which Ka is very large, ionize completely (100%). For weak acids, the percent ionization changes with concentration. The more diluted the acid is, the greater percent ionization. A convenient way to keep track of changing concentrations is through what is often called an I.C.E table, where I stands for "Initial Concentration," C stands for "Change," and E stands for "Equilibrium Concentration." To create such a table, write the reaction across the top, creating the columns, and write the rows I.C.E on the left-hand side. Initial (M)Change (M)Equilibrium (M)A+ B→AB |

Q3. [15 marks] A solid steel shaft (E = 210 GPa, ? = 0.33) of radius 20 mm has been forced into an aluminium gear (E = 70 GPa, ? = 0.33) of outer radius 40 mm and thickness of 10 mm. There is a radial interference of ? = 0.02 mm. a) Determine the contact (interface) pressure, pc ; [6 marks] b) Sketch the radial stress distribution in the shaft and the gear; [5 marks] c) If the coefficient of friction between the shaft and gear is μ = 0.1, what axial force would be required to move the gear along the shaft?

In Java, how can I convert a string user input for example a student starts a uni degree in "Winter/2022", to a date type, and then once I have done that, add 3 years to that value, and changing the season, so for example Student Started: Winter/2022 and Student Finished: Summer/2025. Is there any possible way to do this?
Thank you.
