A set has 62 proper subsets how many elements has it for?<br>

MrRissso [65]

Answer:

Step-by-step explanation:

Total number of subsets is given as

${2}^{n}$

But the subset of a set consists of the proper subsets, an empty set and the set itself.

Total number of subsets are 64

Therefore,

${2}^{n} = 64$

${2}^{n} = {2}^{6}$

Comparing both sides

$n = 6$

An auto shop charges a customer an equal amount for each new tire purchased plus an additional fee for an oil change.

Nitella [24]

The cost per unit of the auto shop function is the slope of the function

87 represents the slope and the cost per tire purchased

The function is given as:

$\mathbf{C(t) = 87t + 32}$

A linear function is represented as:

$\mathbf{C(t) = mt + b}$

Where:

m represents the slope or the unit rate.

So, by comparison:

$\mathbf{m = 87}$

This means that 87 represents the slope and the cost per tire purchased
