Between the 4 and the 7 is it a multiplication or an X?

If the multiplication sign, this is the solution

$- 3x + 6v + 7 \times 14 \\ = 6v - 3x + 98$

The board of a large company is made up of 7 women and 9 men. 6 of them will go as a delegation to a national conference.

Burka [1]

Answer:

a) 5765760

b) 60480

c) 5705280

Step-by-step explanation:

Assuming that order is not important:

Number of women = 7

Number of men = 9

Members of the delegation = 6

a) How many delegations are possible?

$n=\frac{16!}{(16-6)!}=16*15*14*13*12*11\\ n= 5765760$

b) How many of these delegations have all men?

$n_{men} = \frac{9!}{(9-6)!}=9*8*7*6*5*4 \\n_{men} = 60480$

c) How many of these delegations have at least one woman?

$n_{women >0}=n-n_{men}\\n_{women >0} =5765760-60480\\n_{women >0} =5705280$

Answer:

average of all four is 0.74 (add all 4 then divide by 4). take 0.77 minus 0.74. 0.03/0.77 times 100 = 3.8961% to two decimal places would be 3.90%
