The relative atomic mass of aluminium is 27 and of oxygen is 16. The aluminium ore shown below contains 5. 4kg of aluminium and

Assoli18 [71]

Answer:Hope this helps :D

Explanation:

Cu = 27, S = 16 and O = 25.92

relative formula mass = 27 + 16 + (5.4x4.8) = 286.216

only one aluminum atom of relative atomic mass

64 % Cu = 100 x 64 / 160

x = 1036.8

The professor informs the class that there will be a test next week. what is the probability that a randomly selected student st

marusya05 [52]

The probability that students who were randomly selected studied for the test, if they pass it with a B or higher grade is: D. 0.80.

<h3>How to calculate the probability?</h3>

In this exercise, you're required to determine the probability that students who were randomly selected studied for the test, if they pass it with a B or higher grade. Thus, we would apply Bayes's theorem.

Let S represent studied for.

Let B represent a score of B or higher grade

Therefore, we need to find P(S|B):

$S|B = \frac{B|S \times S}{B|S \times S\; +\; B|S' \times S'} \\\\S|B = \frac{0.55 \times 0.6}{0.55 \times 0.6 \;+ \;0.2 \times 0.4}\\\\S|B =\frac{0.33}{0.33 + 0.08} \\\\S|B =\frac{0.33}{0.41}$

S|B = 0.80.

<u>Complete Question:</u>

At the beginning of the semester, a professor tells students that if they study for the tests, then there is a 55% chance they will get a B or higher on the tests. If they do not study, there is a 20% chance that they will get a B or higher on the tests. The professor knows from prior surveys that 60% of students study for the tests. The probabilities are displayed in the tree diagram.
