The table shows the time 50 students spent on their homework.
seraphim [82]

Answer: Mean = 52.8 mins

Step-by-step explanation:

We have lapses of 30 minutes, so we can write the average for each, this means that:

0 < t < 30 can be averaged to the middle of the range: 15 min.

Doing this, we have that:

7 students 15 min

27 students 45 min

12 students 75 min

4 students 105 min.

Now we can calculate the mean:

mean = (x1*n1 + x2*n2 + ...)/N

where x1 is the amount of time 1, and n1 is the number of students associated to that time and so on. N is the total number of students

Mean = (7*15min + 27*45min + 12*75min + 4*105min)/(7 + 27 + 12 + 4)

Mean = 52.8 mins

Write the solution in interval notation: 4v+2&gt;-2 or 3v-5&lt;7
kari74 [83]

For this case we must find the solution of the following inequalities:

4v + 2> -2\ or\ 3v-5

From the first inequality we have:

4v + 2> -2

Subtracting 2 from both sides of the inequality:

4v> -2-2

Equal signs are added and the same sign is placed.

4v> -4

Dividing between 4 on both sides of the inequality:

v> \frac {-4} {4}\\v> -1

Thus, the solution is given by all values of "v" greater than -1.

From the second inequality we have:

3v-5

Adding 5 to both sides of the inequality we have:

3v

Dividing by 3 to both sides of the inequality we have:

v

Thus, the solution is given by all values of "v" less than 4.

Then, the solution set is given by the union of both intervals.

The union consists of all the elements that are contained in each interval.

(-∞,∞)

Answer:

The solution set is: (-∞,∞)
