How can i tell if it's discrete or continuous?
Answers
Discrete variables are counted and only take on certain numerical values, while continuous variables are measured and their probability is calculated over a range of values. The difference between them is reflected in their probability distributions: discrete variables create a probability distribution function (PDF), continuous variables form a probability density function (pdf).
Explanation:Discrete and continuous variables are defined based on how they are measured. Discrete variables are counted, represented by certain numerical values. For instance, the number of books in a backpack or the number of miles you drive to work could be discrete variables.
Continuous variables, on the other hand, are measured. Examples include the distance you drive to work or the weight of a book. A characteristic of continuous variables is that the probability of the variable taking on a single, specific value is zero (P(x = c) = 0), therefore probability is calculated over a range of values.
The distinction between discrete and continuous variables is often highlighted by their probability distribution. Discrete variables create a probability distribution function (PDF), such as counts of chosen values for x. Continuous variables form a probability density function (pdf), which is represented as a curve in the graph, with total probability under the curve equaling 1.

An onion farmer is hiring workers to help harvest the onions. He knows that the number of days it will take to harvest the onions is a function of the number of workers he hires. Explain the use of the word "function" in this context.
Answers
Answer: The word "function" is used to describe that the number of days is dependent on the number of workers.
Number of days = f(number of workers).
Step-by-step explanation:
We know that the more the number of workers will be involved in the harvesting of onion, the lesser days it will take to complete.
Thus, the number of workers becomes the independent variable, which is the input, and the number of days becomes the dependent variable, which is the output.

Which figure is not a polygon? A. Figure A B. Figure B C. Figure C D. Figure D
Answers
A polygon is a closed figure with straight line segments that do not cross over each other. Without seeing the actual figures it's impossible to decide, but if any figure has curved lines, is not closed, or has segments that cross, it would not be a polygon.
Explanation:To determine which figure is not a polygon, we first need to understand what a polygon is. A polygon is a closed figure with a finite number of straight line segments that are connected end to end to form a single shape. The segments should not cross over each other, and the figure must entirely enclose a space.
With this definition, we can examine the provided figures. If any of the figures have curved lines, open sides, or line segments that cross each other, then that figure would not be considered a polygon. Unfortunately, without the visual references of Figures A, B, C, and D, it is impossible to definitively answer which figure is not a polygon. If any figure has one of the aforementioned characteristics, then it would be the correct answer.
For example, if Figure B has curved edges, or if Figure C is not closed, then they would not be polygons. Similarly, if Figure D is a soccer ball with pentagons and hexagons, those shapes are polygons, but if the soccer ball itself is rendered as a three-dimensional spherical object in Figure D, it would not be a polygon.

How do you write 3.25 in simplest form
Answers
Step 1: You would rewrite the decimal number as a fraction with 1 in the denominator. So, 3.25 = 3.24/1
Step 2: Multiply it by 1 to eliminate 2 decimals places, so multiply the top and bottom by 10^2 = 100
3.25/1 x 100/100 = 325/100
Step 3: Now you find the greatest common factor, also known as GCF, of 325 and 100 if it exits then you reduce the fraction by dividing both numerator and denominator by it. GCF = 25
3.25/100 divided by 25/25 = 13/4
Now you would simplify it to make a proper fraction getting your answer

Answers
The florist can make 8 identical bouquets with the same combination of roses and daffodils.
Explanation:To find the largest amount of identical bouquets that can be made with 8 roses and 24 daffodils, we need to determine the highest common factor (HCF) of both numbers. The HCF of 8 and 24 is 8. Therefore, the florist can make 8 identical bouquets with the same combination of 1 rose and 3 daffodils in each bouquet.

I you choose other points, for example (-3.0) and (12,6) the result would be the same.
m=(6-0)(12+3)=6/15=2/5
Answer: the slope would be 2/5
Answer: [tex]\dfrac{2}{5}[/tex]
Step-by-step explanation:
We know that the slope of a line is given by :-
[tex]\text{Slope}=\dfrac{\text{Change in y}}{\text{Change in x}}[/tex]
From the given table , we have
[tex]\text{Slope}=\dfrac{2-0}{\text{2-(-3)}}\\\\\Rightarrow\ \text{Slope}=\dfrac{2}{2+3}\\\\\Rightarrow\ \text{Slope}=\dfrac{2}{5}[/tex]

the width of a singles tennis court is 75% of the width of a doubles Court a doubles court is 36 feet wide how wide is a singles Court
Answers
The width of a singles tennis court is :
75 % x 36 feet
= 75 /100 x 36 feet
= 3/4 x 36 feet
= 27 feet
Hope this helps
The width of a singles tennis court, which is 75% of a doubles court, is calculated to be 27 feet by multiplying the doubles court's width (36 feet) by 0.75.
To find the width of a singles tennis court when given that it is 75% of the width of a doubles court, which is 36 feet wide, we multiply the width of the doubles court by 0.75 (75%). Here is the calculation:
Width of doubles court = 36 feet
Width of singles court = 36 feet × 0.75
Width of singles court = 27 feet
Therefore, the width of a singles tennis court is 27 feet.

What is the unit rate 360 miles traveled on 12 gallons of gasoline
Answers
Thus we divide 360 by 12 to find the appropriate ratio of 1 gallon to miles.
[tex] \frac{360}{12} = \frac{30}{1} = 30[/tex]
The unit rate for traveling on 1 gallon is 30 miles.
We are required to find the unit rate in miles per gallons of gasoline.
The unit rate 360 miles traveled on 12 gallons of gasoline is 30 miles per gallon
Units rate refers to the single unit of one quantity to another. for example; unit of miles to gasolineTotal miles travelled = 360 miles
Total gallons used = 12 gallons
Unit rate in miles per gasoline = Total miles travelled / Total gallons used
= 360 miles / 12 gallons
= 30 miles / 1 gallon
Unit rate in miles per gasoline = 30 miles per gallon
Therefore, the unit rate 360 miles traveled on 12 gallons of gasoline is 30 miles per gallon

(rate going down)(time going down) = distance going down
(4.0 ft/s)(80 s) = 320 ft
Similarly,

distance traveled downward + distance traveled upward = total distance or location
320 feet + 68 ft = 388 feet below sea level

Marty has 6 more pigs than Jen has.After he gives 10 pigs to Jen,how many more pigs will Jen have than Marty?
Answers

:D
jen will have 4 mor epigs than mrty
To find out how many more pigs Jen will have than Marty after Marty gives her 10 pigs, subtract the number of pigs Marty has after giving away 10 from the number of pigs Jen has.
Explanation:To find out how many more pigs Jen will have than Marty after he gives her 10 pigs, we need to determine the initial number of pigs each of them has. Let's assume Jen has x pigs. Since Marty has 6 more pigs, he has x + 6 pigs. After giving 10 pigs to Jen, Marty will have x + 6 - 10 = x - 4 pigs, and Jen will have x + 10 pigs. Therefore, Jen will have (x + 10) - (x - 4) = x + 10 - x + 4 = 14 more pigs than Marty.
