Answer:

40

Step-by-step explanation:

(2/5)*n - 6 = 10 Add 6 to both sides

(2/5)*n - 6 + 6 = 10 + 6 Combine

(2/5)*n = 16 Multiply both sides by 5/2

(5/2)(2/5)n = 16*(5/2)

n = 80 / 2

n = 40

How many distinct proper subsets are there of the set N = {10, 50, 63, 15, 40, 55}?

ASHA 777 [7]

Answer:

$Proper\ Subset = 63$

Step-by-step explanation:

Given

$N = \{10, 50, 63, 15, 40, 55\}$

Required

Determine the proper subsets

This is calculated by:

$Proper\ Subset = 2^n - 1$

<em>Where n is the number of elements in the set.</em>

In this case,

$n = 6$

So:

$Proper\ Subset = 2^n - 1$

$Proper\ Subset = 2^6 - 1$

$Proper\ Subset = 64- 1$

$Proper\ Subset = 63$
