One is negative 4 and one is positive 2
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
I believe about two thirds
Hey there look like you need some help.
If I give you the correct answer mark me brainleist
First you would find the area of the square: 230*230= 52,900Next you would find the area of one on the triangles: 230*187=43,010 * 1/2= 21,505Then you would multiply the area of the one triangle by four: 21,505*4= 86,020Finally, you would add the area of the square to the combined area of the triangles: 86,020+ 52,900=138,920
