Answer:

See below.

Step-by-step explanation:

If they were similar corresponding sides would be in the same ratio.

Testing: 5/4 = 1.25

8/6 = 4/3 = 1.333...

They are not in the same ratio so they are not similar.

marishachu [46]

Answer:

a) 286

b) 1,037,836,800

c) 285

Step-by-step explanation:

a) Since order is not important, the total possible number of ways to choose 10 players out of 13 is the following combination:

$C(13,10)=\frac{13!}{(13-10)!10! } \\C(13,10)=\frac{13*12*11*10!}{(3*2*1)10! }\\C(13,10) = 286$

b) The total number of possibilities to assign positions by the selecting 10 players is the permutation of 13 players for 10 positions:

$P(13,10) = \frac{13!}{(13-10)!}\\P(13,10) = 13*12*11*10*9*8*7*6*5*4\\P(13,10) =1,037,836,800$

c) The number of ways to pick 10 players including at least one woman is equal to the total number of ways to pick 10 players (found in item a) minus the the number of ways to pick 10 players without picking a single woman.

Since there 10 male players for 10 positions, there is only one possible way to pick a team without women, therefore:

$P=286-1 =285$

Diane runs 10 miles in 55 minutes, how many minuets does she take per mile?

Brut [27]

Step-by-step explanation:

Hi!!

 It's simple, you can do it easily. 

no. of miles = 10 miles

time = 55 mins.

now,

no. of mins for 1 mile = no. of miles/ time

 = 10 /55

 =0.18181818 min.

so, she takes 0.181818 or 2/11 min per each mile.

Hope it helps...

5/6 is not the definite ratio, when you take a larger sample size it could be off by a bit like 499/600 or 501/600

The domain is the set of all first elements of ordered pairs (x-coordinates). The range is the set of all second elements of ordered pairs (y-coordinates). Only the elements "used" by the relation or function constitute the range. Domain: all x-values that are to be used (independent values).
