The height of an equilateral triangle h equals 3√2s where s is the length of a side. Suppose an equilateral triangle is made wit

nirvana33 [79]

Answer:

The correct option is;

B. a. Whole number b. Irrational number

Step-by-step explanation:

The height, h of the equilateral triangle = 3·√2·s

The item by which equilateral triangle is made = 2-inch toothpicks

Therefore, we have;

The sides of the equilateral triangle = Comprises multiples of 2 inches

Therefore, the sides of the equilateral triangle is a whole number

The height of the triangle is the product of the side and (√3)/2

Therefore, the height of the triangle is an irrational number

The correct option is A. a. Whole number b. Irrational number.

A whole number are the positive counting numbers, 0, 1, 2, ..., while an integer includes negative numbers which is not possible for a real triangle.

Answer:

$117

Step-by-step explanation:

Given that:

They buy these books for $105 each and sell them to unsuspecting undergraduates at $222 each

Marginal Profit = Marginal Revenue – Marginal Cost.

Marginal Profit = $222 - $105

Marginal Profit = $117

the marginal profit for a single elementary statistics book $117

For the remaining unsold books in the middle of the semester he bundles them up and sells to vendor in another country for $40 each for which he suffers a marginal loss of $105 - $40 = $65 each

Answer :

<h3>The average of a distribution is equal to the summation of x divided by the number of observations is called <u>Mean</u></h3>

Step-by-step explanation:

<h3>The average of a distribution is equal to the summation of x divided by the number of observations is called <u>Mean</u></h3><h3>For :</h3>

We know that $The average (Mean)=\frac{sum of the observations}{Number of observations}$
$Mean=\frac{\sum x}{N}$ where N is the number of observations

<h3>Therefore the average of a distribution is known as Mean.</h3>
