The probability of something can be expressed as a decimal or as a percent. We know that the probability of something happening can not be below 0% or above 100%. Background information: To turn a percent into a decimal (or an integer depending on the number you are working with), you move the decimal two places to the left. For example: 56% would be 0.56 If probability has to be between 0% - 100%, between what two integers does probability have to be after you convert from a percent to an integer? *
Answer: The probability lies between 0 and 1
Step-by-step explanation:
As from the given information probability of an event lies between 0% to 100% .
To convert percent into integer or fraction we have to divide it by 100
[tex] 0\%= \frac{0}{100} = 0 [/tex]
And
[tex] 100\% = \frac{100}{100} = 1 [/tex]
From the above the probability of an event lie between integers 0 to 1.

A farmer has 180 bushels of wheat to sell at her roadside stand. She sells an average of 16 and three fourths bushels each day. Represent the total change in the number of bushels she has for sale after 5 days.
To find the total change in the number of bushels the farmer has for sale after 5 days, multiply the average number of bushels sold per day by the number of days.
Explanation:To find the total change in the number of bushels the farmer has for sale after 5 days, we need to multiply the average number of bushels sold per day by the number of days.
The average number of bushels sold per day is 16 and three fourths, which can be written as 16.75.
Multiplying 16.75 by 5 gives us the total change in bushels after 5 days, which is 83.75 bushels.

What is 673.983 rounded to the nearest hundredth
I believe it would be 673.98
I hope this helps :)
673.983 rounded to the nearest hundredth is 673.98, as the third decimal digit (3) is less than 5.
To round the number 673.983 to the nearest hundredth, we need to look at the third decimal place, which is in the thousandths place. If this digit is 5 or greater, we round up. If it is less than 5, we keep the second decimal place as it is. In the case of 673.983, the third decimal digit is a 3, which is less than 5. Therefore, the number rounded to the nearest hundredth is 673.98.
What are the domain and range of the function below?
Answer:
Domain is the set of all real numbers
Range is the set of all real numbers.
Step-by-step explanation:
Given a graph with curve which has y intercept -5, and x intercept 5.
The graph is continuous at all points of x and y
We find that the graph is a straight line with positive slope of the form
x/5 +y/-5=1
Or x-y =5
The graph is defined for all values of x and y.
The domain is the set of values x can take
In the graph horizontal axis is x axis.
Hence from the graph we see that x can take values from -infinity to + infinity
Hence domain is x = R
For range, we consider the values of y as per graph.
WE find that y is taking values in the interval (-infinity, infinity)
Hence Range =R
The term 'domain' in mathematics refers to the complete set of possible values of the independent variable in a function. The 'range' on the other hand, represents the possible results of the function after an experiment or survey. These values are not always numerical but could be a set of words or phrases.
Explanation:The domain of a function is the complete set of possible values of the independent variable. In the context of your question, it can be a list such as X = {English, Mathematics,...} representing all the majors offered at a university, or it can be a numerical set, for example Y = {0, 1, 2,...} representing the integers from zero up to the upper limit of classes. Even functions like Z where the domain includes any amount of money from zero upwards can exist.
Similarly, the range of a function is the set of all possible values that the function can take after the experiment is performed or the question is answered. For instance, if a function has a domain of hair color, its range would be the different hair colors like black, blond, gray, green, orange, etc. This shows that the domain and range of a function are not necessarily numerical.
The specific value x the function takes only becomes known after performing the experiment or survey. However, there might be certain values that are outside the domain of the function and as such, would not give a reliable prediction, just like 90 in the dataset from 65 to 75. Such an occurrence doesn't fall within the domain of the function and can't be accurately predicted.

A 13.5-gasoline tank is 4 / 5 full how many gallons will it take to fill the tank
Two investments totaling $58,500 produce an annual income of $3795. One investment yields 5% per year, while the other yields 7% per year. How much is invested at each rate?
Total investment is =$58500
Annual income produced = $3795
Rate of one investment = 5%
Rate of second investment = 7%
Let the amount invested at 5% be = x
Then, amount invested at 7% rate will be = [tex]58500-x[/tex]
The equation becomes:
5%x + 7%(58500-x) = 3795
= 0.05x + 0.07(58500-x) = 3795
0.05x + 4095 - 0.07x = 3795
0.02x = 300
x = 15000
Hence, the amount invested at 5% is = $15000
Amount invested at 7% = 58500-15000 = $43500

Factor the expression
Factor a^2−2ab−6by+3ay
a^2−2ab+3ay−6by
=(a−2b)(a+3y)
Answer:
(a−2b)(a+3y)
the factored expression is:
a(a + y) - 2b(a + 3y)
We can factor the expression [tex]a^2-2ab-6by+ay[/tex] using a combination of grouping and factoring by difference of squares:
We can group the terms based on common factors:
[tex](a^2 + ay) - (2ab + 6by)[/tex]
In the first group, a is the common factor: a(a + y)
In the second group, 2b is the common factor: 2b(a + 3y)
Then we combine the terms
a(a + y) - 2b(a + 3y)
Therefore, the factored expression is:
a(a + y) - 2b(a + 3y)

We can write this line in y-intercept form, and then solve to convert it to standard form.
Y = mx + b
m = slope
b = y-intercept
Y = -1/4x - 2 is the slope-intercept form of the equation.
Now, we can convert this to standard form.
Add 2 to both sides.
y + 2 = -1/4x
Subtract y from both sides.
-1/4x - y = 2
Multiply all terms by -4.

Aurora has a cell phone plan that charges

for phone service plus
$12
for each gigabyte of data used each month. If her bill for September is
$113,
how many gigabytes of data did she use in September?
Aurora used 4 gigabytes of data in September.
Explanation:To determine how many gigabytes of data Aurora used in September, we need to subtract the fixed phone service charge from her total bill. The difference will represent the additional charges for the data usage. Let's say she used x gigabytes. The equation for her bill can be written as: 65 + 12x = 113. To solve for x, we can subtract 65 from both sides and then divide both sides by 12 to isolate x. Solving this equation, we find that x = 4. So, Aurora used 4 gigabytes of data in September.

and
[tex]y=2----equation (2)[/tex]
This is a simultaneous equation in [tex]x[/tex] and [tex]x[/tex].
But the coefficient of [tex]x[/tex] in the second equation is zero. that is why it seems to be absent.
We solve these two equations simultaneously
by putting [tex]y=2[/tex] in to equation (1).
Tis gives;
[tex]2=4x-10[/tex]
We add 10 to both sides to get;
[tex]12=4x[/tex]
we divide through by 4 to get

The product of x and the sum of 6 and 8 times the square of x
"·" - product
"+" - sum
x² - square of x
Answer: x · (6 + 8 · x²) = x(6 + 8x²)
The expression "the product of x and the sum of 6 and 8 times the square of x" can be written as [tex]\( x \cdot (6 + 8x^2) \)[/tex].
The mathematical expression "the product of x and the sum of 6 and 8 times the square of x" is represented as [tex]\( x \cdot (6 + 8x^2) \)[/tex]. To simplify, distribute x into the parentheses, yielding 6x + 8x^3. This expression captures the specified operation, where x is multiplied by the sum of 6 and 8 times the square of x.
It is essential to follow the order of operations, ensuring that the square of x is calculated first, then multiplied by 8, and finally added to 6 before multiplying the result by x. This expression forms the algebraic representation of the described mathematical operation.
