The following table shows the number of snow days each school district in Trene County had last winter.
School district
District 201
District 211
District 221
District 231
District 241
Number of snow days
4
8
3
6
If the mean of the data set is 5 snow days, find the number of snow days in District 241.
snow days

4

Step-by-step explanation:

The mean (or average) is the sum of all snow days divided by number of districts.

5 = (4 + 8 + 3 + 6 + x) / 5

25 = 21 + x

x = 4

The answer is 4.

Multiply the mean and the number of districts for the total.

Then add up all the number of snow days.

Lastly, subtract the total and the number of snow days.

(mean)5 x 5(districts) = 25

4+8+3+6= 21

25-21= 4

ANSWER: 4

12.5 feet

step-by-step explanation:

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
