Each of 8 students reported the number of movies they saw in the past year. This is what they reported: 18, 10, 20, 18, 12, 19,1
lakkis [162]

Answer:

I. Mean = 15

II. Median = 15

Step-by-step explanation:

<u>Given the following data;</u>

Total number of students = 8

x = 18, 10, 20, 18, 12, 19,12, 11

F(x) = 18 + 10 + 20 + 18 + 12 + 19 + 12 + 11

F(x) = 120

To find the mean;

Mean = F(x)/n

Mean = 120/8

Mean = 15

To find the median;

<em>Median refers to the middle number of a sorted data</em>.

x = 10, 11, 12, 12, 18, 18, 19, 20

Middle numbers = 12 and 18

Median = (12 + 18)/2

Median = 30/2

<em>Median = 15</em>

In the figure shown, which pair of angles must be supplementary?
nignag [31]

Answer:

Option C. ∠PQT and ∠TQS are supplementary.

Step-by-step explanation:

When the addition of two angles give 180° Then the pair of angles is called as supplementary.

Means we have to search the angles which are on a straight line.

Option A. ∠PQT and ∠PQS sum is more than 90 but less than 180.

Option B. ∠PQT and ∠TQS sum of these angles is 90°

Option C. ∠PQT and ∠TQR sum is 180° so pair is supplementary

Option D. ∠TQS and ∠SQR sum is less than 180°.

Therefore option C is the answer.
