It has been proved that the double-shaft clubs re- sult in longer drives. so if our drives are longer, then you are using these elu

The conclusion is invalid.

The required diagram is shown below:

Step-by-step explanation:

Consider the provided statement.

It has been proved that the new double-shaft clubs result in longer drives. So if our drives are longer, then you are using these clubs.

From the above statement we can concluded that new club users are the subset of longer drives.

If you use double shaft you will definitely drive longer but if you drive longer  it is not necessary that you used a double shaft. It may be other factors.

Therefore, It may possible that you can drive longer without using the new clubs.

Therefore, the conclusion is invalid.

The required diagram is shown below:

answer: - (a)

(b) 88 seats

step-by-step explanation:

given: in an auditorium, there are 22 seats in the first row and 28 seats in the second row.

thus first term=

second term=

the number of seats in a row continues to increase by 6 with each additional row.

⇒d= 6

a) given formula :

b)   let the number of seats (n) = 12

substitute n=12 in the explicit rule formed in (a)

∴there are 88 seats in 12 rows.

i think its 7.6

if so your welcome
