A researcher has collected the following sample data. The mean of the sample is 5. 3 5 12 3 2 Refer to Exhibit 3-2. The coefficient of variation is _____.
Answer:
81.24%
Step-by-step explanation:
First we solve for the variance
Sample space of
3,5,12,3,2
n = 5
Variance = s²
= (3-5)²+(5-5)²+(12-5)²+(3-5)²+(2-5)²/5-1
= 4+0+49+4+9/4
S² = 66/4
= 16.5
Secondly we find the standard deviation
= √16.5
= 4.062
Coefficient of variation
Cv = sd/mean x 100
= 4.062/5 x 100
= 406.2/5
= 81.24%

What is Equation of Graph of Polynomials?
Graphs behave differently at various x-intercepts. Sometimes the graph will cross over the x-axis at an intercept. Other times the graph will touch the x-axis and bounce off.
Identify the even and odd multiplicities of the polynomial functions' zeros.
Using end behavior, turning points, intercepts, and the Intermediate Value Theorem, plot the graph of a polynomial function.
The graphs cross or are tangent to the x-axis at these x-values for zeros with even multiplicities. The graphs cross or intersect the x-axis at these x-values for zeros with odd multiplicities
Given data ,
The equation is f ( x )
f ( x ) = ( x² + 2x + 1 ) ( x - 4 )
On Simplifying the equation , we get
f ( x ) = ( x³ - 4x² + 2x² - 8x + x - 4 )
Now , this is a polynomial equation and can be plotted on a graph and is shown below

324 - 1.6 = 322.4 is the height of the right triangle. This is the opposite side compared to the angle theta.
The adjacent side is 550 since it is the leg closest to the angle theta.
We'll use the tangent rule to connect the two sides
tan(angle) = opposite/adjacent
tan(theta) = 322.4/550
theta = arctan(322.4/550)
theta = 30.3780566013696
theta = 30.4
Your teacher didn't provide any rounding instructions, but I rounded to one decimal place since the value 1.6 is to one decimal place.

A small scoop of ice cream holds 75% as much as a large scoop of ice cream.
If the small scoops holds 36 ounces, how much does the large scoop hold? _______________ ounces.
Answer:
48 ounces
Step-by-step explanation:
75% of x = 36
= 0.75x = 36
Dividing both sides by 0.75 we get:
x = 36/0.75
x = 48 units
The large scoop can hold 48 ounces.
What are percentages?A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate the percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word percent means per 100. It is represented by the symbol “%”
Given here: A small scoop of ice cream holds 75% as much as a large scoop of ice cream. Let the large scoop hold x then as per question we have x×0.75=36
x= 48
Hence, The large scoop can hold 48 ounces.
