1. A poll asked 15 men in two age groups, 40 and younger and older than 40, whether they watched the Super Bowl or not The results are recorded in the table.

Person Age group Watched the Super Bowl

1 40 and younger Yes
2 40 and younger No

3 Older than 40 No

4 40 and younger No
5 Older than 40 No

6 Older than 40 Yes

7 Older than 40 Yes
8 Older than 40 No

9 40 and younger Yes

10 40 and younger Yes
11 Older than 40 Yes

12 40 and younger Yes

13 Older than 40 Yes
14 40 and younger No

15 Older than 40 Yes

(a) Create a two-way table of the data. Of the men surveyed, how many were older than 40? How many men did watch the Super Bowl?

How many were older than 40? 8 men

How many men did watch the Super Bowl? 9 men

Step-by-step explanation:

Let's make a processed data out of the list:

1. 40 and younger + Yes

Subject no: 1,9,10,12

2. 40 and younger + No

Subject no: 2,4,14

3. Older than 40 + Yes

Subject no: 6,7,11,13,15

4. Older than 40 + No

Subject no: 3,5,8

The table should look like this

           Yes       No      Total

<=40       4         3         7

>40         5         3         8

Total       9         6         15

There are a total of 8 men older than 40 and a total of 9 men who watch the super bowl.

step-by-step explanation:

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
