How to solve for 40! / 10!30!

nlexa [21]

40! / 30! = 40*39*38*37*36*35*34*33*32*31

dividing this by 10! 10*9*8*7*6*5*4*3*2*1

= 4*13*19*37*17*11*4*31

= 847,660,528

yan [13]

Answer:

The sum of all the possible values for z that satisfy the above equation is -5.

Step-by-step explanation:

The given equation is

$\frac{5}{z}-\frac{2z+4}{z+2}=-3$

We need to find the sum of all the possible values for z that satisfy the above equation.

The given equation can be rewritten as

$\frac{5}{z}-\frac{2(z+2)}{z+2}=-3$

Cancel out common factors.

$\frac{5}{z}-2=-3$

Add 2 on both sides.

$\frac{5}{z}-2+2=-3+2$

$\frac{5}{z}=-1$

$5=-z$

Multiply both sides by -1.

$-5=z$

Only z=-5 satisfy the given equation.

Therefore the sum of all the possible values for z that satisfy the above equation is -5.

A survey of 125 households was done to investigate whether households have laptops, tablets, or

riadik2000 [5.3K]

Answer:

3) 0.326

Step-by-step explanation:

Total Number of surveyed households =125

We want to determine the probability that a randomly selected household would have a laptop given that it does not have a tablet.

Written in Probability notation: P(Laptop|No Tablet)

$P(Laptop|No Tablet)=\dfrac{P(L\cap T')}{P(T')} \\=\dfrac{31/125}{95/125}\\=\dfrac{31}{95}\\\\=0.326$

The correct option is C,

Leora wants to paint the nursery on her house. The nursery is an 8-by-13-foot rectangle, and the ceiling is 9 feet tall. There i

Anna007 [38]

Answer:

336 ft²

Step-by-step explanation:

The rectangle is 13 ft long and 8 width that means we have two walls 8* 9 and two walls 13*9

Total walls area is

2*8*9 + 2*13*9 = 144 + 234 = 378 ft²

then we subtrac , areas of door, closet and windows

3 * 6.5 = 19,5 ft²

3 * 6,5 = 19,5 ft²

2 * 1,5 = 3 ft²

42 ft²

Then area to paint 378 - 42 = 336 ft²

Fill in the blanks, using the Associative Property of Multiplication: (8 X 1) 3 = 8 x ( x 3) - = 8x

hammer [34]

Step-by-step explanation:

Consider the provided multiplication.

We need to use associative property of multiplication.

Associative property of multiplication:

$(a\times b)\times c = a\times (b\times c)$

Now use the above property and solve the provided multiplication:

$(8 \times 1)\times 3 = 8 \times (1 \times 3)$

$8\times 3 = 8 \times 3$

$24 = 24$

The multiplication is verified by associative property.
