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.

GOD HALP MEEE: It takes Lucas 3 hours to cycle from his home to his friend's village. But if he travels 5 mph slower, it will ta

Bumek [7]

Answer:

45 miles

Explanation:

Speed = distance / time

Lets assume :

speed = x

Distance = D

Time = 3 hours

so in first case :

x = D / 3

D = 3x

Second case :

speed = x-5 ( he is traveling 5mph slower )

Distance = D ( Distance is same )

time = 4.5 hour

so,

x-5 = D / 4.5

D = 4.5(x-5)

since D is same in both cases.

3x = 4.5(x-5)

3x = 4.5x - 22.5

4.5x - 3x = 22.5

1.5x = 22.5

x = 22.5/1.5

x= 15

so speed is 15mph

D= 3x

so Distance = 3*15 = 45 Miles.
