What percentage of the data values are greater than 80?
64.71% percent of the data values are greater than 80.
What is the percentage?
In Ancient Rome, long before the actuality of the decimal system, computations were constantly made in fractions in the multiples of '/ 100', For illustration, Augustus levied a duty of1/ 100 on goods sold at sale known as centesimal Rerum valium. Computation with these fractions was original to calculating chances. They named it as a percentage.As nomenclatures of capitalism grew in the Middle ages, computations with a denominator of 100 came increasingly standard, analogous that from the late 15th century to the early 16th century, it came common for calculation-handbooks to include analogous computations known as percentage.Multitudinous of these handbooks applied these styles to profit and loss, interest rates, and the Rule of Three. By the 17th(seventeenth) century, it was standard to quote interest rates in hundredthsMin. value = 30

In the figure below, m4=96°. Find mZ1, mZ2, and mZ 3.
The answer is m∠1 = 84°
Step-by-step explanation:
m∠4 = m∠2 so m∠2 = 96°
m∠1 + m∠2 = 360 - m∠4 - m∠2
m∠1 + m∠2 = 360 - 96 - 96
m∠1 + m∠2 = 168

Suppose that y is directly proportional to x. use the given information to find the constant of proportionality k. then use y = kx to find y for the given value of x. y = 30 when x = 10;find y given x = 14
The the value of constant proportionality k is 3 and the value of y is 42 when the value of x is 14.
Constant proportionality:
Constant proportionality means the ratio of two proportional values at a constant value.
Directly Proportional:
In direct proportion, if one quantity is increased or decreased then the other quantity increases or decreases, respectively.
Given,
Suppose that y is directly proportional to x.
And y = kx.
Here we need to find the value of k when the value of x = 10 and the value of y = 30.
And we also need to find the value of y when the value of x = 14.
First, we have to find the value of k by apply the given value of the equation,
=> 30 = k x 10
=> 30 /10 = k
=> k = 3
Now the value of y when the value of x = 14 and the value of k = 3,
Then
=> y = 3 x 14
=> y = 42.
Therefore, the value of constant proportionality k is 3 and the value of y is 42 when the value of x is 14.

Find the product of 2√/18 and 2√5 in simplest form. Also, determine whether the
result is rational or irrational and explain your answer.
2√10/3 is irrational number
The term "rational number" refers to any number that can be stated as a fraction, as well as a positive, negative, or zero. If q is not equal to zero, it can be expressed as p/q.
The word "rational" is derived from the word "ratio," which is a fraction and really refers to a comparison of two or more values or integer numbers. It is the ratio of two integers, to put it simply.
Consider the rational integer 3/2. It denotes that the integer 3 is divided by the number 2.
Irrational numbers are those that are not rational in nature. Let's explain; irrational numbers can be expressed as decimals but not as fractions, hence they cannot be expressed as the ratio of two integers.
After the decimal point, irrational numbers have an infinite amount of non-repeating digits. Here's an illustration of an irrational number:
For instance, 8 = 2.828
MULTIPLYING THE TWO NUMBERS,
2/√18 x 2√5
= 2 /3√2 x 2√5
= 4√5/3√2
= 2√2 x √5 /3
= 2√10/3
rational number multiplied by an irrational number is always a irrational number.
Since √10 is a irrational number, therefore, 2√10/3 is irrational number.

MODELING REAL LIFE Bowling alley A charges $3.75 to rent shoes and $4 per game. Bowling alley B charges
$2.50 to rent shoes and $4.50 per game.
a. For what numbers of games is the total cost, including a pair of rental shoes, less at bowling alley A? at bowling
alley B?
Bowling alley A:__ or more games
Bowling alley B:__
or __
games
b. Bowling alley A increases the cost per game by $0.50. How does this affect your answer in part (a)?Explain.
Using linear functions, we have that:
a. For 6 or more games, the cost a bowling alley A is less, and for 4 or less games, the cost at bowling alley B is less.
b. For any number of games, the cost at alley B will be less.
What is a linear function?
A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.For the functions in this problem, we have that:
The slope is the cost per game.The intercept is the cost of 2 shoes.Hence they are given as follows:
A(x) = 4x + 7.5.B(x) = 4.5x + 5.The cost for A will be less when:
A(x) < B(x).
Hence:
4x + 7.5 < 4.5x + 5
-0.5x < -2.5
0.5x > 2.5
x > 2.5/0.5
x > 5.
Hence for 6 or more games, the cost a bowling alley A is less, and for 4 or less games, the cost at bowling alley B is less.
For item b, with the increase of $0.5 per game, we have that:
A(x) = 4.5x + 7.5.
Then the costs per game will be the same, while alley B has the lower intercept, meaning that for any number of games, the cost at alley B will be less.

Find the area of the region enclosed by the curves y = 7 sin x and y = sin(7x) , 0 < x
The area of the region enclosed by the curves y = 7sin x and y = sin(7x) , 0 < x < π is 13.7 square units.
Given the equation of the curves:
y = 7sin x and y = sin(7x)
Now, we have to find the area between the curves .
Area between y = 7sin x and y = sin(7x) ,
A = ∫[7sin(x) - sin(7x)]dx
⇒ A = [-7cos(x) + 1/7 cos(7x)]
⇒ A = [-7cos + 1/7 cos(7)] - [-7cos(0) + 1/7 cos(0)]
Since cos(π) = -1 ; cos(7) = -1 ; cos(0) = 1
⇒A = [-7(-1) + 1/7 * (-1)] - [-7 * 1 + 1/7 * 1]
⇒A = 7- 1/7 + 7 - 1/7
⇒A = 14 - 2/7

A
The age of the man is years from the average age of men in the city. The age of the woman isyears from the average age of women in the city.
the absolute deviation for the man is 3 years more than the one for the woman.
How to compare the deviations?We know that the absolute value function:
m(x) = |x - 44|
Represents the absolute deviation of man's age, in years.
This means that the average age of a man in that city is 44 years old, so if a man has 64 years, then the absolute deviation is given by:
m(64) = |64 - 44| = 20
The absolute deviation for a man of 64 years old living in this city is 20 years.
Similar for the case of women, the equation here is:
w(x) = |x - 47|
If a woman has 64 years old, then the absolute deviation is:
w(64) = |64 - 47| = 17
The absolute deviation is 17 years.

The “Cricket Season” is the period of days where cricket is played in a country when the pitches get dry and also this is the period where the domestic matches begin.
And this season varies with countries, in India it starts with the Ranjit Trophy, Sheffield Shield for Australia etc.
Cricket seasons are the times of the year when cricket is played. Because top-class cricket is almost always played outdoors, on uncovered pitches, and rain prevents play, the seasons in each country are geared to coincide with the driest months of the year
The cricket season starts at the beginning of April and finishes at the end of September. As the time zones move around the planet, the seasons will differ in other countries.
In the UK,
professional games have occasionally taken place at the end of March but the season will normally begin at the start of April.
In India
The cricket season in India will usually begin in mid-September. Often, there are senior women’s games starting things off before men’s tournaments commence in October.

Which is more affected by extreme observations, the mean or median? and how about the standard deviation or iqr?
Mean and standard deviation is more affected by extreme observations.
Mean is the summation of all the values divided by the total number of values. It is also called as average. Median is the middle value.Standard deviation is the dispersion of a dataset relative to its mean. In case of extreme items arithmetic mean is affected very much. For this reason, it no longer remains representative of the distribution. As standard deviation is the positive square root of the arithmetic mean of the square of deviations of all given values, it is also affected by extreme items. As median is a partition value, it is not affected by extreme items.
