The given statement describes descriptive statistics.
What is Descriptive statistics?In the count noun sense, a descriptive statistic is a summary statistic that quantitatively describes or summarizes features from a collection of data, whereas descriptive statistics (in the mass noun sense) is the process of using and analyzing those statistics. Descriptive statistics differ from inferential statistics (or inductive statistics) in that they seek to summarize a sample rather than learn about the population that the sample of data is thought to represent. This generally means that, unlike inferential statistics, descriptive statistics are not based on probability theory and are frequently nonparametric statistics. For example, knowing that all of the participants in our example wore blue shoes would be useless.Therefore, the given statement describes descriptive statistics.

Solve the equation
-2 = 2 + v/4
The simplification of the equation - 2 = 2 + v/4 is v = - 16.
Equation, which is defined as the quality of being equal, is frequently represented by a mathematical expression with equal values on either side or by a situation in which numerous factors must be taken into account.
Consider the equation,
-2 = 2 + v/4
The equation can be rewritten as:
-2 = 2/1 + v/4
The least common multiple or LCM of 1 and 4 is 4.
-2 = ( 2 × 4) / (1 × 4) + v /4
-2 = 8/4 + v/4
-2 = ( 8 + v) /4
Multiplying each side of the equation by 4
- 2 × 4 = [ ( 8 + v ) / 4 ] × 4
- 8 = 8 + v
Subtracting each side of the equation by 8.
- 8 - 8 = 8 + v - 8
v = - 16

A tree is standing next to a 40 foot high building the tree has a 9 foot shadow of the building has 18 foot shadow how tall is the tree rounded to the nearest foot
The height of the tree is 80 feet
How to determine the height of the tree?The given parameters are:
Building = 40 ftShadow of the building = 9 ftShadow of the tree = 18 ftThe above parameters can be represented as:
Building : Shadow of the building = Tree : Shadow of the tree
This gives
40 : 9 = Tree : 18
Express as fraction
40/9 = Tree/18
Multiply both sides by 18
Tree = 80
Hence, the height of the tree is 80 feet

the normal model n(58,21) describes the distribution of weights of chicken eggs in grams. suppose that the weight of a randomly selected chicken egg has a z-score of -2.01. what is the weight of this egg in grams? round to the nearest hundredth of a gram.
The weight of the egg is 15.79 grams.
Normal Distribution:
Normal distribution, refers the probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean.
Given,
The normal model n(58,21) describes the distribution of weights of chicken eggs in grams.
suppose that the weight of a randomly selected chicken egg has a z-score of -2.01.
Here we need to find the weight of the egg and we have to round off it to the nearest hundredth of gram.
Let X the random variable that represent the weights of a population, and for this case we know the distribution for X is given by:
So,
X ~ n(58, 21)
Where this means the value of
σ = 21
[tex]\mu[/tex] = 58
Apply the values on the formula,
[tex]Z=\frac{x-\mu}{\sigma}[/tex]
=> -2.01 = (x - 58) / 21
=> -2.01 x 21 = x - 58
=> -42.21 + 58 = x
=> x = 15.79
So, the weight of the egg is 15.79 grams.
When we round off it to the nearest hundredth then we get,
=> 15.79
Because there is no hundredth term in this one.

Ascending order is 1/6< -4/-9< 11/12 < -21/ -18.
Here the fraction is -4/-9, 11/12, -21/-18, 1/6.
To know write the fraction in its ascending form, and convert the fraction into it's decimal form.
Therefore we have,
-4/-9 = 4/9 = 0.44
11/12 = 0.916
-21/-18 = 21/18 = 7/ 6 = 1.16
1/6 = 0.16
Therefore ascending order is 0.16< 0.44< 0.916 < 1.16. That is 1/6< -4/-9<11/12 < -21/-18.

By using fundamental concepts of fractions we can conclude that Jarome can make 6 [tex]\frac{7}{8}[/tex] pizzas with the leftover cheese.
Define fractions.Fractions are one of the most important aspects of arithmetic that we use in our daily lives. Fractions are denoted by the symbol / (also known as the fractional line) and represent a numerical value that is a portion of the total value, for example, a/b. Formulas for fractions aid in the development of rules for performing the four basic arithmetic operations of addition, subtraction, multiplication, and division.
Given data:
Cheese used for making 2 [tex]\frac{3}{4}[/tex] pizza = 2 [tex]\frac{1}{2}[/tex]
Cheese used for making 1 pizza = 2 [tex]\frac{1}{2}[/tex] ÷ 2 [tex]\frac{3}{4}[/tex]
Cheese used for making 1 pizza = 10/11
Number of pizza pies that can be made from 6 [tex]\frac{1}{4}[/tex] cheese = 6 [tex]\frac{1}{4}[/tex] ÷ 10/11
Number of pizza pies that can be made from 6 [tex]\frac{1}{4}[/tex] cheese = 55/8
