If one of the 255 subjects is randomly selected, find the probability that the person is over 40 years of age.
The probability that the person is over 40 years of age is 32/51 or 62.75%.
(the table is attached as image)
We know that,
The ratio of the size of the event space to the size of the sample space is the probability of an event.
The total number of possible outcomes is the size of the sample space.
The number of outcomes in the event you are interested in is called the event space.
Using the formula,
P = size of the event space/size of the sample space
⇒The probability that the person is older than 40,
sample size=255
size of the event space=85
P=85/255------> P=1/3
⇒the probability that the person drinks root beer,
sample size=255
size of the event space=75
P=75/255------> P=5/17
⇒the probability that the person is older than 40 of age or that they drink root beer,
P=(1/3)+(5/17)-----> P=(17*1+3*5)/51------> P=32/51-----> 0.6275----> 62.75%

Angelica purchases $25.75 worth of cosmetics online. There is a 2% processing fee. What is the total cost of the cosmetics? Round to the nearest cent
26.27
Step by step
2/100 = 0.02
0.02 x 25.75 = 0.51
0.51 + 25.75 = 26.26 rounding is 26.27
The total cost of the cosmetics including 2% processing fee rounded up to the nearest cent is $26.27
The cost of the cosmetics is $25.75
The 2% processing fee is calculated as follows:
2/100 × $25.75 = $ 0.515
The total cost including processing fee is $25.75 + $ 0.515 = $26.265 rounded up to $26.27

what is the functional for seven less than 3/5 of B is A
The mathematical expression is 3/5b -7 = a.

An absolute numerical number is referred to as a constant.Variable: A symbol without a set value is referred to as a variable.Term: A term can be made up of a single constant, a single variable, or a mix of variables and constants multiplied or divided.Coefficient: In an expression, a coefficient is a number that is multiplied by a variable.Given:
7 less than three fifths of b is a
So, the mathematical expression for the above statement is
(3/5)b - 7 = a
3b - 35 = 5a
3b- 5a= 35

julia rides her bike at a rate of 1/2 mile per 1/9 of an hour. how far does she ride in one hour
Answer:
4.5 miles
Step-by-step explanation:
0.5 of a mile per 1/9 of an hour.
rate x time=distance and you need to find distance for one hour not 1/9 so multiply it by 9 so
0.5*9=4.5, 1/9*9=1
rate time distance
4.5 * 1 = d
4.5*1=d
4.5=d
so the distance traveled in one hour is 4.5 miles
Answer:
4.5 miles
Step-by-step explanation:
Given:
Julia rides her bike at a rate of 1/2 mile per 1/9 of an hour.Let x be the distance Julia rides in one hour.
Create an equivalent ratio of miles to hours:
[tex]\implies \dfrac{1}{2}:\dfrac{1}{9}=x:1[/tex]
[tex]\implies \dfrac{\frac{1}{2}}{\frac{1}{9}}=\dfrac{x}{1}[/tex]
[tex]\implies \dfrac{1}{2}\times \dfrac{9}{1}}=x[/tex]
[tex]\implies \dfrac{9}{2}=x[/tex]
[tex]\implies x=4.5[/tex]
Therefore, Julia rides 4.5 miles in one hour.
Line A is represented by the equation y=4x−6. How do these equations compare to line A?
The comparison of the linear functions to line A are given as follows:
y = 4x ± constant: parallel.y = -x/4 ± constant: perpendicular.y = x/4 ± constant: neither parallel nor perpendicular.When are lines parallel, perpendicular or neither?A linear function is defined as follows:
y = mx + b.
In which the coefficients are listed as follows:
m is the slope.b is the intercept.The slope determines if the lines are parallel, perpendicular, or neither, as follows:
If the slopes for both lines are equal, the lines are parallel.If the multiplication of the slopes of both lines is of -1, they are perpendicular.Otherwise, they are neither.In this problem, the function is:
y = 4x - 6.
Hence the slope is of:
m = 4.
Then the functions, relative to y = 4x - 6, are classified as follows:
Parallel: slope of 4.Perpendicular: slope of -1/4, as 4 x (-1/4) = -1.Neither: any slope different of 4 and of -1/4.Missing InformationThe problem gives three lines with different slopes, and you have to define if they are parallel, perpendicular or neither parallel nor perpendicular.
The intercepts are not relevant and I couldn't find the problem on the internet, hence I say that they are constants.

The domain and range of the relation shown in the table include the following: A. domain:{−3, −1, 2, 4}, range:{0, 2, 4}.
What is a domain?In Mathematics, a domain can be defined as the set of all real numbers for which a particular function or relation is defined.
This ultimately implies that, a domain is the set of all possible input values (x-values) to a relation, and the domain of a graph comprises all the input values which are located on the x-coordinate from the least to the greatest.
Additionally, a range is the set of all real numbers that is associated with the elements of a domain i.e all of the y-values shown on the y-coordinate of the graph of a relation, from the least to the greatest.
By critically observing the table of this relation shown, we can reasonably infer and logically deduce the following:
Domain = {−3, −1, 2, 4}.

If r(x) = 2x² and w(x) = x-2, what is the range of (wor)(x)?
The given function are
r(x) = 2 - x² and w(x) = x - 2
(w*r)(x) can be obtained by multiplying the both function together
So, (w*r)(x) = w(x) * r(x) = (x-2)*(2-x²)
(w*r)(x) = x (2-x²) - 2(2-x²)
= 2x - x³ - 4 + 2x²
∴ (w*r)(x) = -x³ + 2x² + 2x - 4
It is a polynomial function with a domain equal to R
The range of (w*r)(x) can be obtained by graphing the function
To graph (w*r)(x), we need to make a table between x and (w*r)(x)
See the attached figure which represents the table and the graph of (w*r)(x)
As shown in the graph the range of (w*r)(x) is (-∞,∞)
Zach loves to compete in triathlons. At a race a few months ago, he finished in 280 minutes. Yesterday, he completed another triathlon and finished in 294 minutes. What was the percent of increase in Zach's finishing time?
The percent of increase in Zach's finishing time is 5%.
How to calculate the percentage?From the information, at a race a few months ago, he finished in 280 minutes and yesterday, he completed another triathlon and finished in 294 minutes.
The increase in time will be:
= New time - Old time
= 294 - 280
= 14 minutes
The percentage increase will be:
= Increase in time / Original time × 100
= 14 / 280 × 100

Function A has a rate of change of 5 & function B has a rate of change of -4.5. so, function A has a greater rate of change.
What is the rate of change?
The rate at which a variable changes over a given time period. It is frequently used when discussing momentum, and it can be expressed as a ratio of a change in one variable to a corresponding change in another. This ratio is represented graphically by the slope of a line.
For the first function, we can use the equation of the slope
[tex]m = \frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]
take any two points,
m = (25-15)/5.5-3.5 = 10/2 = 5
The general equation of a straight line is;
y = mx + c
where m is the slope
Therefore, in the case of the second equation, -4.5 is the slope
Hence, function A has a rate of change of 5 & function B has a rate of change of -4.5. so, function A has a greater rate of change.

What is the length of the base edge?
The length of the base edge of the pyramid is 1.71 feet
What is surface area of a pyramid?In order to find the total surface area, we will need to add up the areas of the base and the three other sides. SA=B+12(P×h), where B is the area of the base of the pyramid, P is the perimeter of the base, and h is the slant height of the pyramid.
If l is the length of the square base and h is the height of the pyramid, then h =2/3l
from the formula, SA= B+12(P×h)
the perimeter of a square is 4l
the base area of square is l^2
therefore 96= l^2+ 12(4l×2/3l)
96= l^2+ 12×8/3l^2
96=l^2+32l^2
96= 33l^2

A boat is heading towards a lighthouse, where Yaritza is watching from a vertical distance of 139 feet
Yaritza measures an angle of depression to the boat at point AA to be 21°
Yaritza takes another measurement and finds the angle of depression to the boat (now at point BB) to be 50°
