Looking for the height, if trapezoid area equals (a+b)/2 x h then h = 2A/(a+b)
so h = 2(30)/(4.8+5.2) = 6

Evaluate 7P4<br> Evaluate 12C5

Verdich [7]

Answer:

Below.

Step-by-step explanation:

7P4

= 7! / (7-4)!

= 7*6*5*4*3*2*1 / ( 3*2*1)

= 7*6*5*4

= 840.

12C5

= 12! / (12-5)! 5!

= 12*11*10*9*8*7*6*5*4*3*2*1 / ( 7*6*5*4*3*2*1 * 5*4*3*2*1)

= 12*11*10*9*8 / 5*4*3*2*1

= 792.

What is the value of x?

Kazeer [188]

Answer:

Step-by-step explanation:

The volume of a sphere is

$V=\frac{4}{3}\pi r^3$

We are told our volume is 500pi/3, so we fill that in and solve for r:

$\frac{500\pi}{3}=\frac{4}{3}\pi r^3$

Start by multiplying both sides by 3 over 4 pi:

$(\frac{3}{4\pi})\frac{500\pi}{3}=(\frac{3}{4\pi})\frac{4\pi}{3}r^3$

Simplifying gives us

$125=r^3$

Take the cubed root of both sides to get that

r = 5

Step-by-step explanation:

R=7

B=7

Total=14

P(one red marble)=7/14=1/2

P(another red marble no replacement)=6/13

1/2 times 6/13=6/26=3/13
