The highest value is the highest positive integer, which is 3720.
The lowest value is the negative value, -92.
To obtain the difference between the two, subtract -92 from 3720. thus we have the following:
[tex]3720-(-92)[/tex]Add the additive inverse of -92 to 3720.
[tex]3720-(-92)=3720+92=3812[/tex]you are visiting new Orleans, la and a taxi company charges a flat fee of $2.75 for using the taxi and $0.35 per mile write an equation
We have a fixed fee of $2.75, independent of the miles.
We also have to add a variable fee, the depends on the number of miles (lets call them x), that is $0.35 per mile.
Then, we can write the total fee as:
[tex]C(x)=2.75+0.35\cdot x[/tex]Calculate the second and third derivative of y =9x-1/x
y = 9x - 1/x
I like to rewrite 1/x as x^-1
y = 9x - x^-1
Taking the derivative
dy/dx = 9 - -1 x^-2
= 9 + 1/x^2
That is the first derivative
Now we do it again
dy^2/dx^2 = d/dx ( 9 + 1/x^2)
= d/dx( 9 + x^-2)
= 0 -2x^-3
=-2/x^3
The second derivative is -2 / x^3

what is this need to know Which model represents the product 6×34?
The model in the bottom-left represents the product 6×(3/4).
We are given two numbers. The first number is 6, which is a whole number. The second number is 3/4, which is a simple fraction. We need to represent the product of these two numbers in the form of the given models. The images of the models are attached below. The first number is already a whole number, so we can represent it with six whole horizontal blocks. The second number is a fraction, so we can represent it as 3 blocks out of 4, where 4 blocks combined represent the number 1. Hence, the bottom-left model represents the product.

sugar cookies require 2 cups of flour for every 2/3 cups of sugar. how much sugar for 5 cups of flour
Billy, this is the solution to the exercise:
For answering it, we will use the Direct Rule of Three, this way:
Sugar (cups) Flour (cups)
2/3 2
x 5
____________________________
x * 2 = 5 * 2/3
2x = 10/3
Dividing by 2 at both sides:
2x/2 = 10/3 / 2
x = 10/3 * 1/2
x = 10/6
x = 1 2/3 (simplifying)
We will need 1 2/3 cups of sugar for 5 cups of flour

The total volume of a tree increases 8% each year. What will its volume be after 7 years if it’s volume is 5 m³ now?
The volume of trees after 7 years if it’s volume is 5 m cube now is 8.57 m cube.
In the given question we have to find the volume be after 7 years if it’s volume is 5 meter cube now.
The increment in tree each year = 8%
At now the volume is 5 meter cube.
Time = 7 years
So the formula is used to find the volume after 7 years
A=P(1+ r/100)^n
A=volume after 7 years
P=now the volume of tree
n=time
Putting the values
A=5(1+ 8/100)^7
A=5((100+8)/100)^7
A=5(108/100)^7
A=5(1.08)^7
A=5×1.714
A=8.57
Hence, volume of trees after 7 years if it’s volume is 5 m cube now is 8.57 m cube.

How many lines are determined by 18 points, no 3 of which are collinear?
First, consider the 3 points, no 3 of which are collinear; as shown in the diagram below
As one can see, we can form 3 different lines, lines 12, 13, and 23 (this is 2+1=3).
Similarly, in the case of 4 points,
There are 6 possible lines when considering 4 points on the plane (3+2+1=6).
Finally, in the case of 5 points on the plane,
4+3+2+1=10 lines when 5 points.
Therefore, for 18 points, there are 17+16+15+14+...+3+2+1=153

Swap x and y variables:
x = 1/2 (3-3y)
Solve for y:
x = 1/2(3)+1/2(-3y)
x= 3/2 -3/2y
x-3/2 = -3/2y
(x-3/2) / -3/2 = y

Annie will be left with 0.9 yd of string with her.
What is subtraction?In maths, to subtract means to take away from a group or a number of things.
Given that, Annie had a string of 13 yd, and she used 12.1 yd of the string for her backpack.
The length of string left with her after using for backpack = 13-12.1 = 0.9 yd
Hence, Annie will be left with 0.9 yd of string with her.

The United States Department of Agriculture (USDA) found that the proportion of young adults ages 20–39 who regularly skip eating breakfast is 0.238 . Suppose that Lance, a nutritionist, surveys the dietary habits of a random sample of size =500 of young adults ages 20–39 in the United States.Use a normal approximation to find the probability that the number of individuals, , in Lance's sample who regularly skip breakfast is greater than 124 .(>124)= (Round to 3 decimal places)
Answer
The answer is 0.300
Problem Statement
We are asked to find the probability that the number of individuals in a survey of 500 people would skip breakfast given that the proportion of people who skip breakfast, in general, is 0.238.
Method
- The proportion of people greater than 124 out of 500 is easily gotten to be:
[tex]\begin{gathered} p>\frac{124}{500} \\ p>0.248 \end{gathered}[/tex]- We now need to know the probability that the proportion of people that skip breakfast would be greater than 0.248.
- To calculate this probability, we need to find the Z-score associated with this value. This is a good way to approximate the probability because the number of people in the survey is well above 30 and we have been told to apply a normal approximation.
- Once we have the Z-score associated with this proportion of 0.248 in relation to the general population proportion statistic of 0.238, we can then convert the Z-score into a probability using a Z-score calculator or a Z-table.
- If the Z-score is "z", then, the probability we are looking for on the Z-score table or calculator is P(x > z).
- Thus, we can solve the question using the following steps:
1. Calculate the Z-score using the formula below:
[tex]\begin{gathered} z=\frac{p-p_0}{\sqrt[]{\frac{p_0(1-p_0)}{n}}} \\ \\ \text{where,} \\ p=\text{sample proportion} \\ p_0=\text{population proportion} \\ n=\text{ Total number of people in the survey} \end{gathered}[/tex]2. Convert the Z-score into probability
Implementation
Step 1: Calculate the Z-score:
[tex]\begin{gathered} p=0.248,p_0=0.238 \\ \\ z=\frac{0.248-0.238}{\sqrt[]{\frac{0.238(1-0.238)}{500}}} \\ \\ z=\frac{0.01}{0.019045} \\ \\ z=0.5251 \end{gathered}[/tex]2. Convert the Z-score into probability:
Using the Z-score calculator, we have:
Because we are asked to find the probability that the number of people who skipped breakfast is greater than 124, the correct probability here is P(x > Z).
Thus, the probability that the number of individuals that skipped breakfast is greater than 124 is 0.29977 ≅ 0.300 (To 3 decimal places)
Final Answer
The answer is 0.300.
