A local produce stand has eight pumpkins on display the diameters of the pumpkin in inches are given in the table
Answers
SOLUTION
We will be pairing the pumpkins as follows
AB, CD, EF and GH
For AB, we have
[tex]\begin{gathered} 16\frac{1}{2}\div5\frac{1}{2} \\ \frac{33}{2}\div\frac{11}{2} \\ \frac{33}{2}\times\frac{2}{11} \\ =\frac{33}{11} \\ =3 \end{gathered}[/tex]Hence B is 3 times larger than A
For C and D, we have
[tex]\begin{gathered} 41\frac{1}{4}\div8\frac{1}{4} \\ \frac{165}{4}\div\frac{33}{4} \\ \frac{165}{4}\times\frac{4}{33} \\ =\frac{165}{33} \\ =5 \end{gathered}[/tex]Hence D is 5 times larger than C
E and F, we have
[tex]\begin{gathered} 13\frac{3}{4}\div3 \\ \frac{55}{4}\div\frac{3}{1} \\ \frac{55}{4}\times\frac{1}{3} \\ =\frac{55}{12} \\ =4.5833333333 \\ =4.583 \end{gathered}[/tex]Hence E is 4.583 times larger than F
And the last G and H, we have
[tex]\begin{gathered} 22\frac{3}{4}\div10\frac{1}{2} \\ \frac{91}{4}\div\frac{21}{2} \\ \frac{91}{4}\times\frac{2}{21} \\ =\frac{91}{21\times2} \\ =\frac{91}{42} \\ =2.167 \end{gathered}[/tex]Hence G is 2.167 times larger than H

What is the Percentage?
A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.
What is Percentage change?
The percentage increase is calculated by subtracting the original number from the new number, dividing that result by the original number, and multiplying that result by 100.
where growth in number equals new number minus initial number.
Similar to how a percentage increase is calculated, a percentage reduction is calculated by subtracting a new number from the original number, dividing that new number by the original number, and multiplying that result by 100.
decreasing number where original number - new number
In other words, there is a percentage decline if the response is negative.

Answers
The model is a linear function that shows $3.25 money that Ilya has all together
What is meant by a linear function?The phrase linear function relates to two distinct but related concepts in mathematics:
Some authors use the term "linear function" only for linear mappings that accept values in the scalar field; these are more frequently known as linear forms.
Calculus' "linear functions" qualify as "linear mappings" when (and only when) f(0,..., 0) = 0, or, equivalently, when the aforementioned constant b equals zero.
A linear function in calculus and related fields is one whose graph is a straight line, that is, a polynomial function of degree zero or one. The word affine function is commonly used to distinguish such a linear function from the other idea.
A linear function is also known as a linear map in linear algebra, mathematical analysis, and functional analysis.

The z-score is given as
x = 29
s = 3.6
z = -1.5
