The ways can the jazz band be selected so there are 2 trumpet players, 5 drummers, and 3 saxophonists is given below .
Step-by-step explanation:
Let's first do the math with only the trumpet,drummer and saxophonists player.
There are 4 Trumpet Player. There are 4 choices of trumpet players. Which means for each drummer, there are 4 groups of musicians:
T
1
D1S1
T
1
D2S2
and so on
So if there are 4 groups of musicians for each Trumpet ,12 drummer and there are 7 saxophonists , we get 12 groups.
It would be the product of
4T2, 12D5 and 7S3
That is 6*792*35=166,320
9w+63=27
27-63= -36
-36•/•9=-4
answer: -4=w
hope this helps
Let <em>y</em> be the expression you want to differentiate:

Now,

Use the chain rule to differentiate both sides with respect to <em>x</em> :

Solve for d<em>y</em>/d<em>x</em> :



Answer:
36.25 is equal to the 45.5% of 79.67
Step-by-step explanation:
To solve this you just have to find the value that represents the 100%.
To do this, you can use the Rule of Three that allows you to solve problems of proportions.
In this case, you know that the 45.5% of the magnitude <em>X </em>is 36.25, now you have to find the value which corresponds to the 100%.
Mathematically it will be:

Then you have to solve the equation to find <em>X</em>:

And finally, the answer is:

Answer:
Step-by-step explanation:
Just estimating, about 15%
% = Land used for food production/ Total Area * 100
% = (570000 / 3.931 * 10^6) * 100%
% = 14.5%
