The track increased 400m:


1600 - 1200 = 400



Use the rule of 3:


1200 - 100%

400 - x


(400 * 100) / 1200 = x

40 000 / 1200 = x

33,33... = x


The increase was of 33% aproximately.




Hope it helped,


Happy homework/ study/ exam!

Answer:

1 < a < 13/5

Step-by-step explanation:

2 < 2a - 3(1 -a) < 10

2 < 2a - 3 + 3a < 10

2 < 5a - 3 < 10

2 + 3 < 5a - 3 + 3 < 10 + 3

5 < 5a < 13

5/5 < 5a/5 < 13/5

1 < a < 13/5

A baseball team has 15 field players and 10 pitchers. Each field player can take any of the 8 non-pitching positions. What is th
leonid [27]

Answer:

If order matters: 2,594,592,000 ways.

If order does not matter:  64,350 ways

Step-by-step explanation:

Assuming that the order matters when picking the non-pitching positions (since they are different positions), the number of possible different starting lineups is given by the permutation of picking 8 players out of 15, multiplied by 10 (pick one out of 10 pitchers):

n =10*\frac{15!}{(15-8)!}\\ n=10*15*14*13*12*11*10*9*8\\n=2,594,592,000

Now if the order of the field players is not important, the number of possible starting lineups is given by the combination of picking 8 players out 15, multiplied by 10:

n = n =10*\frac{15!}{(15-8)!8!}\\ n=\frac{10*15*14*13*12*11*10*9*8}{8*7*6*5*4*3*2} \\n=64,350

Therefore, the number of ways to pick the starting lineup is:

If order matters: 2,594,592,000 ways.

If order does not matter:  64,350 ways
