35 49 51 54 65 51 52 47 87 37 46 33 39 44 39 64 94 34 30 48
is the sample given
From the above we can find
Mean =sum of all observations /20
= 
Variance = ![\frac{1}{20} [\Sigma_1^{20} (x_i-49.95)^2 ]\\=269.7475](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B20%7D%20%5B%5CSigma_1%5E%7B20%7D%20%28x_i-49.95%29%5E2%20%5D%5C%5C%3D269.7475)
Std deviation= square root of variance
= 16.424
Population estimate for mean = 49.95
Population estimate for std dev =
=3.673
The value that separate 50% top form 50% bottom is the median
Median is the middle value after arranging in ascending order
=average of 47 and 48 = 47.5
Proportion of atleast 60 = 2/20 = 0.1
The quadrilateral ABCD is an isosceles trapezoid, and the length of AC for the quadrilateral is 19 feet
<h3>How to determine the
length of AC?</h3>
The quadrilateral ABCD is an isosceles trapezoid
This means that:
- Opposite sides are equal
- The diagonals are also equal
From the above highlights, we have:
AC = 7ft + 12ft
Evaluate the sum
AC = 19 ft
Hence, the length of AC for the quadrilateral is 19 feet

A mathematical equation for checkerboard borders can be determined with any shape based on the expression given.
<h3>How to illustrate the information?</h3>
In mathematics, an algebraic expression is the expression that is built up from integer constants, variables, and the algebraic operations
It should be noted that an equation is a mathematical statement that is made up of two expressions connected by an equal sign.
For example, 3x – 5 = 16 is an equation. Solving this equation, we get the value of the variable x as x = 7. This can be illustrated in the shape.

Answer:
<h2> $287.50</h2>
Step-by-step explanation:
From the problem statement the cost price per box is
$250.
And the box contains 4 specific powers, since Zeus plans to make $900 per box which contains 4 powers
we need to find the selling price
profit= selling price-cost price
let the selling price be x
900=x- 250
x=900+250
x= 1150
Selling price = $1150
<em>Hence the unit cost of a specific power in a box that will see a profit of $900 per box is 1150/4= $287.50</em>
