True or False
Rama09 [41]

Answer:

True

Step-by-step explanation:

Permutation is act of arranging members of a set while combination is selection of the items from collection.

The number of permutation of r object out of n is:

^nP_r=\frac {n!}{(n-r)!}

The number of combinations of r object out of n is:

^nC_r=\frac {n!}{(n-r)!\times r!}

Or,  

^nC_r=\frac {^nP_r}{r!}

So, number of the permutations of r objects out of n is greater than number of the combinations of r objects out of n.

What is the area of a rectangle with a width of 4 2/3 meters and a length of 2 1/6 meters?
inessss [21]

Answer:

Area = 10 1/9 meters squared

Step-by-step explanation:

mixed number to improper fraction:

4 2/3 meters = 14/3 meters

2 1/6 meters = 13/6 meters

Area = length times width:

Area = (14/3) x (13/6)

        = 182/18

Simplify fraction:

182/18 = 91/9

improper fraction to mixed number:

91/9 = 10 1/9 meters

AREA = 10 1/9 meters
