Answer:

The coach can do this in 3,003 ways

Step-by-step explanation:

Here, the coach needs to select a team of 5 from a total of 15 players

Mathematically, the number of ways this can be done is simply 15 C5 ways

Generally, if we are to select a number of r items from n items, this can be done in nCr ways = n!/(n-r)!r!

Applying this to the situation on ground, we have;

15C5 = 15!/(15-5)!5! = 15!/10!5! = 3,003 ways

Answer:

The weight of grapefruit is now 80 pound.

Step-by-step explanation:

Consider the provided information.

Let the x is the weight loss. The weight of grapefruit is 100 pounds and water is 92%. After evaporation water is 90%.

Thus the weight loss is:

$0.92\times100-0.90(100 - x) = x$

$92-90+0.90x=x$

$2=x-0.90x$

$2=0.1x$

$x=20$

Hence, the weight loss is 80 pounds.

Therefore, New weight is 100 - 20 = 80 pounds

The weight of grapefruit is now 80 pound.
