Estimate the probability of the event.Of 1,966 people who came into a blood bank to give blood, 337 people had high blood pressure. Estimate the probability that the next person who comes in to give blood will have high blood pressure.

Consider the following probability. P(−2.5 ≤ z ≤ 1) Shade the area under the standard normal curve corresponding to the probability above. FIG. 1 FIG. 2 FIG. 3 FIG. 4 FIG. 5

Coral bleaching is a sign that the coral is doing very well and is healthy.

A reaction Gibbs energy, ΔG, is sometimes not easy to determine experimentally. However, if the chemical reaction is a redox reaction that can be assembled into the form of a voltaic cell, then the Gibbs energy, ΔG, can be measured using just a volt meter! Consider the following redox reaction: 2 NO3− + 8 H+ + 3 Cu → 2 NO + 4 H2O + 3 Cu2+ It is a complicated reaction! You should be happy that you donate need to understand but in order to answer this question. Although it is complicated looking, it can be setup as a voltaic cell, where the voltage, Ecell, is measured to be +0.62 V on a voltmeter. What is the Gibbs energy of the redox reaction above as written, in kJ (to 1 decimal place)? You also need to know that there are 6 electrons involved in this reaction. Use the following to determine ΔG. ΔG = -n F Ecell F = 96,485 Coulombs/mol
