Answer:
12870ways
Step-by-step explanation:
Combination has to do with selection
Total members in a tennis club = 15
number of men = 8
number of women = 7
Number of team consisting of women will be expressed as 15C7
15C7 = 15!/(15-7)!7!
15C7 = 15!/8!7!
15C7 = 15*14*13*12*11*10*9*8!/8!7!
15C7 = 15*14*13*12*11*10*9/7 * 6 * 5 * 4 * 3 * 2
15C7 = 15*14*13*12*11/56
15C7 = 6,435 ways
Number of team consisting of men will be expressed as 15C8
15C8 = 15!/8!7!
15C8 = 15*14*13*12*11*10*9*8!/8!7!
15C8 = 15*14*13*12*11*10*9/7 * 6 * 5 * 4 * 3 * 2
15C8 = 6,435 ways
Adding both
Total ways = 6,435 ways + 6,435 ways
Total ways = 12870ways
Hence the required number of ways is 12870ways
Answer:
x = 6

210 = 35x
x = 6
The number of individual people represented in the person data set as indicated by the person_if is; 9 individuals.
The number of contacts made with people from family 3 as in the task content is; 3 contacts, namely, G, H and I.
<h3>How many individual people are represented in the person dataset?</h3>
As evident in the task content, we are expected to access the table and evaluate the data representation in order to draw inferences from observation.
The person_id column assigns an alphabet to each individual.
Hence, the total number of individuals represented in the person data set is; 9 individuals.
Also, since only persons G, H and I are evaluated in family 3, it follows that the total number of individuals checked in family 3 is; 3.
