Explanation
To determine the probability that the number rolled is odd using a standard die, we first list the total outcomes as shown below:
1,2,3,4,5,6
As we can see, the odd numbers are:
1,3,5
This means that the total favorable outcomes is 3.
Now, we use the formula:
[tex]Probability=\frac{favorable\text{ outcomes}}{Total\text{ outcomes}}[/tex]We plug in what we know:
[tex]\begin{gathered} Probab\imaginaryI l\imaginaryI ty=\frac{favorable\text{ outcomes}}{Total\text{ outcomes}} \\ =\frac{3}{6} \\ Simplify \\ Probab\mathrm{i}l\mathrm{i}ty=\frac{1}{2} \end{gathered}[/tex]Therefore, the probability that the number rolled is odd is 1/2.
Answer:
3/6
A standard die has 6 sides, numbered 1 through 6 (1,2,3,4,5,6). That means we have 3 odd numbers (1,3,5) and 3 even numbers (2,4,6).
The total possible outcomes of an odd number are 3, because there are 3 odd numbers, and the total outcomes are 6. So we write it as 3/6, like 3 out of six chances of getting an odd number.
It can be simplified to 1/2.

Identify the parent function for the function g (x) = x + 4 based on its function rule. Then graph g and identify the transformation of the parent function that it represents.Linear; translation up 4 unitsConstant; translation up 4 unitsLinear; translation down 4 unitsConstant; translation down 4 units
linear; translation up 4 units
Explanation:The given function is:
g(x) = x + 4
This is of the form:
y = mx + c
where m is the slope and c is the y-intercept
Therefore, g(x) is a linear function
The parent function is:
g(x) = x
g(x) = x + 4 means that the function is translated up 4 units
Calculate the pay for the following day of a weekly time card given a wage of $14.50/hr.

The undergraduate library at State U tends to have 33.4 students enter every hour during normal operation. Over the next two hours, what is the probability at least 75 students arrive at the library?
The probability that at least 75 students arrive at the library is 0.1440.
How to calculate the probability?From the information, the undergraduate library at State U tends to have 33.4 students enter every hour during normal operation.
The expected number of students for the two hours will be:
= 2 × 33.4
= 66.8
The probability that at least 75 students arrive at the library will be:
P(x >= 75) = 1 - P(x <= 74)

The coordinates of point A are (-2,5). The coordinates of point B are (3,5). Which expression represents the distance, in units, between A and B?
The distance expression of the number of units between points A and B is √[(-2 - 3)^2 + (5 - 5)^2]
How to determine the expression of the distance between A and B?From the question, we have the following parameters:
The coordinates of point A are (-2,5). The coordinates of point B are (3,5).This means that
A = (-2, 5)
B = (3, 5)
The distance between the points is calculated as
Distance = √[(x2 - x1)^2 + (y2 - y1)^2]
Where
A = (x1, y1) = (-2, 5)
B = (x2, y2) = (3, 5)
Substitute the known values in the above equation
So, we have
Distance = √[(-2 - 3)^2 + (5 - 5)^2]
The question does not imply that the we simplify the above expression
So, we leave the expression unsimplified
Hence, the expression of the distance between A and B is √[(-2 - 3)^2 + (5 - 5)^2]

Volume of solid of revolution formed by rotating about the x axis the region between the graph of f(x)= x /2 and the x axis between x=2 and x=5 is 117π /12unit³.
As given,
Volume of solid of revolution formed by rotating about the x-axis region between the graph of f(x)= x /2:
Volume = π∫[f(x)]²dx

Step-by-step explanation:
Mr smith wants to put fence around his yard the dimensions of the yard are 61ft by 39ft the fencing is sold in whole meters how much fencing should he buy
The most appropriate choice for perimeter of rectangle will be given by-
Mr Smith must buy 61 m of fencing.
What is perimeter of rectangle?
It is equal to the total distance of the boundary of the rectangle.
If length of rectangle is l m and breadth of rectangle is b m, perimeter of rectangle is 2 x (l + b) [tex]m^2[/tex]
Here,
Length of yard = 61 ft
Breadth of yard = 39 ft
Perimeter of yard = 2 x (61 + 39)
= 2 x 100
= 200 ft
1 ft = 0.305 m
200 ft = 0.305 x 200 m
= 61 m

Use what you know about domain to select all of the following functions that could be the one graphed.
Using transformations, the functions that could represent the one graphed are given as follows:
y = sqrt(x) - 3.y = sqrt(x) - 1.What is a transformation?A transformation is when a function undergoes a change in it's definition. Depending on the type of the transformation, the function can keep the same orientation, same side lengths, and so on.
In the context of this problem, the function kept the same orientation, it just changed it's position, hence the type of transformation that the function underwent was a translation.
The possible translations are given as follows:
Translation down, changing the range.Translation up, changing the range.Translation left, changing the domain.Translation right, changing the domain.The domain of the graphed function is given by:
x ≥ 0.
Which is the same domain as the parent square root function, given as follows:
y = sqrt(x).
From the graph, the function was translated down a units, changing it's range, hence the function has the following format:
y = sqrt(x) - a.
Hence the first two options can be correct, either with a = 1 or with a = 3. The last two options change the range but not the domain, hence they are incorrect.

Brian's final exam in math had two parts. He had a total of 60 minutes to complete the entire exam. He spent 15 minutes on Part 1 of the exam. Write and solve an equation to show how much time he had left to complete Part 2.
m over 15 equals 60; m = 900 minutes
m − 15 = 60; m = 75 minutes
15 + m = 60; m = 45 minutes
15m = 60; m = 4 minutes
Answer:
15 + m = 60; m = 45 minutes
Step-by-step explanation:
Hello!
According to the question He had a total of 60 minutes to complete the entire exam. He spent 15 minutes on Part 1 of the exam. how much time he had left to complete Part 2.
Let's make an equation where the time spent on part 1 which is 15 + m which is minutes remaining for part 2 is equal to Total minutes which is 60 minutes
So, if we put it together;
15 + m = 60
So, let's solve for m
15 + m = 60
Substract 15 from both sides
15 - 15 + m= 60 - 15
m = 45
So, the equation is 15 + m = 60 and he had 45 minutes of time remaining to complete part 2.

Provide your answer below:
The domain of f⁻¹(x) is (9,∞).
The function we have is
f(x) = 4x² + 9 for x ≤ 0
Now, let us find the inverse of the function f(x),
To find the inverse of f(x),
Replacing f(x) with f(y)
f(y) = 4y² + 9
Now the equation is,
x = 4y² + 9
y² = (x-9)/4
y = √(x-9)/2
The inverse of f(x) is,
f⁻¹(x) = √(x-9)/2
The domain of √(x-9)/2 can be found as,

area is 4pi r². Determine the rate at which the surface area is changing with respect to time when r = 40 cm.
(Use symbolic notation and fractions where needed.)
Answer:
The rate at which the surface area is changing with respect to time when r = 40 cm is 22400π cm²/min
Not sure if you want it in absolute values since the question says use symbolic notation but if so, multiplying by π gives 70371.675 cm²/min
Step-by-step explanation:
[tex]\text {Volume of a sphere of radius r is given by }\\\\ \text {$V = \dfrac{3}{4}\pi r^3$}[/tex]
The surface area of a sphere of radius r is given by:
[tex]\\S = 4\pi r^2\\[/tex]
The rate of change of surface area is given by
[tex]\dfrac{dS}{dt} = \dfrac{d}{dt}\left(4\pi r^2\right)}\\\\\dfrac{dS}{dt} = 4 \pi \dfrac{d}{dt}\left( r^2\right)}\\\\\\\dfrac{d}{dt}(r^2) = 2r\dfrac{dr}{dt}\\\\\\[/tex]
[tex]\dfrac{dS}{dt} = 8\pi r \dfrac{dr}{dt}[/tex]
We are given that [tex]\text{$\dfrac{dr}{dt}$}[/tex] = 70 cm/min and asked to find rate of change of S when r = 40 cm
Substituting these values into the equation for [tex]\dfrac{dS}{dt}[/tex]
[tex]\dfrac{dS}{dt} = 8 \pi \cdot 40 \cdot 70\\\\\\\\\dfrac{dS}{dt} = 22400 \pi \;cm^2/min[/tex]
In absolute values
