vagabundo [1.1K]

Answer:

-39991'

Step-by-step explanation:

We require the sum of 7 terms of the G.S.  -1, 6, -36  .....

The common ratio r = 6/-1 = -6 and the first term = -1.

Sum of n terms = a1 . (r^n  - 1) / (r - 1)

Sum of 7 terms = -1 * (-6)^7 - 1)  / (-6 - 1)

=  -1 * 39991

= -39991 (answer).

Ilya [14]

Answer:

Step-by-step explanation:

At a Baseball Match.

35% of spectators are New York Yankees fan

The rest are Boston Red Sox fan = 100 - 35% = 65%

30% of fans in both teams are females.

30% of 35% of spectators are New York Yankees fan = 0.105 females

30% of 65% of spectators are Boston Red Sox fan = 0.195 females

The number of males in New York Yankees fan = 1 - 0.105 females

= 0.895 males

The number of males in Boston Red Sox fan = 1 - 0.195 females

= 0.805 males
