What is your recommendation for the maximum size of coarse aggregate for the following situation? A continuously reinforced concrete pavement cross section contains a layer of No.6 reinforcing bars at 6-inch centers, such that the steel is just above mid-depth of a 10-inchthick slab. Cover over the top of the steel is therefore about 4 inches.
Assume that I work in a Magazine Agency, and I am instructed to create
an advertisement for the School. The objective is for the school to
increase its market share. Can you create an eye-catching ad to promote the institution.
A project specifies a concrete strength of at least 3000 psi. Materials engineers will design
the mix for a strength higher than that. Calculate the required average compressive strength of
the mix design if the standard deviation is s = 350 psi. Estimate the modulus of elasticity of the
concrete at the required average compressive strength.

You have been appointed as a public relations manager of a government department. You are tasked with developing a public relations programme or campaign, using the seven steps (theory) of the public relations programme (DOTMABE formula), to raise awareness of and advocate against xenophobic attacks on illegal immigrants in South Africa. Please note that you are given a budget of R20 million, and you need to travel to five provinces of your choice that are mostly affected by this scourge. In developing your programme, you need to make use of the rubric below as a guideline.

a. Working hours and leaves
b. Protection measures and compensation
The weights of male students are normally distributed with a mean of 150 lbs. and a standard deviation of 25 lbs. What is the probability that 25 randomly selected make students will have a mean weight of more than 155 lbs?
The design engineer specifies a concrete strength of 5500 psi. Determine the required
average compressive strength for:
a. A new plant where s is unknows
b. A plant where s = 500 psi for 22 test results
c. A plant with extensive history of producing concrete with s = 400 psi
d. A plant with extensive history of producing concrete with s = 600 psi
A test taken by five people has a maximum score of 100. Their scores are 78, 65, 86, 91 and 68.
