NO ONE CAN SOLVE THIS, NEITHER CAN YOU :::By what percent will a fraction change if its numerator is decreased by 10% and its de

Veseljchak [2.6K]

Answer:

9/5

Explanation:

original fraction : x/y

new fraction = .9x/(.5y)

= 9x/5y

(9x/5y) / (x/y)

= 9x/5y * y/x

= 9/5

= 1.8

so it increased by 80%

e.g suppose we had 100/200 or 1/2

new fraction = 90/100 or 9/10

new ratio = (9/10) / (1/2)

= 9/5

The kind of ROI Luis demonstrates is : Positive ROI

<h3>Positive ROI</h3>

A positive ROI is defined as when the cost of a financial decision/step is lower than the gain of a financial decision.

Luis takes a loan to help him earn a certificate, the certificate he earns has helped him earn a good salary job which he can use to repay the loan.

Therefore in the long term Luis will have a positive return on investment on his financial decision.

Hence we can conclude that the kind of ROI Luis demonstrates is Positive ROI.

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.
