Using Venn probabilities, it is found that 240 students are enrolled in both classes.
<h3>Venn probabilities:</h3>
The events are:
- Event A: A student is enrolled in band.
- Event B: A student is enrolled in chorus.
The supposed percentages, which also represents the probabilities involving a single student, are:
- 50% of the students involved in the band, hence
.
- 40% of the students involved in the chorus, hence
.
- 30% involved in neither, hence
.
The percentage involved in both is:
Hence:
Then, out of 1200 students:
240 students are enrolled in both classes.

<u>Answer: </u>
If they worked together it would take 4 hours for the machines to produce 100 widgets
<u>Step-by-step explanation:</u>
w = widgets hr = hour ph = per hour
Old machine - 50w = 5hr = 10ph
New machine - 30w = 2hr = 15ph
Old machine - 20w = 2hr
New machine - 30w = 2hr
<h3>Together - 50w = 2hr x 2 </h3><h3> Final: 100w = 4hr</h3>

Step-by-step explanation:
the median is the middle value of the list. first off, write the list of numbers in ascending order (small to big)
3, 4, 4, 5, 7, 7, 8, 10, 10, 10
since there are 10 values, there are two middle numbers which are 7 and 7. since they are both 7, the median is 7
