Hey there!!

How do we solve this problem :

We will use the combinations formula to solve this :

c ( n , r ) where n = 11 and r = 2

c ( n , r ) =  n ! / r ! ( n - r ) !

... 11 ! / 2 ! ( 11 - 2 ) !

... 11! / 2! × 9!

... 11! / 2 × 9!

... 11×10×9×8×7×6×5×4×3×2 / 2×9×8×7×6×5×4×3×2

... 11×10 / 2

... 11 × 5

... 55 combinations.

Hence, the required answer = 55 , option ( d )

Hope my answer helps!

Which mathematical sentence most Accurately expresses the information in the problem below?
d1i1m1o1n [39]

Answer:

Don't quote me on this but it's probably C. 12c ≥ 88

Step-by-step explanation:

This is because he packages 88 eggs <em>into </em>cartons of 12.

88/12 is 7.33333... so it makes sense to have a greater or equal amount of eggs. If you multiply 7.333333... by 12, each additional 3 gets you closer to 88 so again, makes sense to have more.

How to solve these equations
nlexa [21]
All u have to do is plug in the values
68) -(4q) = -(4*-3) =-4*3= -12
70) 5P-6= (5*5)-6 =25-6= 19
72) 7q-7p= 7(-3)-7(5) = -21-35= -56
74)2q/(4p) = 2(-3)/4(5)= -6/20= -3/10

Jason and Kyle both choose a number from 1 to 10 at random. What is the probability that both numbers are odd?
Artemon [7]
Your answer is 

B) 1/2

because there are 5 odd and 5 even numbers from 5 through 10, so it would be 1/2.

Glad I could help, and good luck!

What is the anwere to this problem in the simple form
Deffense [45]
It is in simple form. There is absolutely nothing more that can be done, unless it is a joke. And math jokes are very hard to come by.

I don't think that y(y - 1)/(a + 2b) is any simpler.

Come to think of it, is that x^2 or y^2 on the top left. 
I think my first answer is the best one. Nothing can be done.
