The students will make a line plot of the data. They will use only one fraction in their scale. They must be able to plot all of the data above a label. Which should this fraction be?
Step-by-step explanation:
To determine the appropriate fraction for the line plot, we need to find the greatest common factor (GCF) of all the pencil lengths, and then express each length as an equivalent fraction with the GCF as the denominator.
The GCF of the pencil lengths is 1. Therefore, we can simply express each pencil length as an equivalent fraction with 1 as the denominator:
3/1, 7/1, 8/1, 5/1, 1/1, 4/1, 6/1, 8/1, 4/1, 2/1, 5/1
Now, we can see that the smallest unit increment we can use on the line plot is 1/8. This is because 1/8 is the smallest fraction that can represent all of the pencil lengths above the label (5/8, which is equivalent to 10/16).
Therefore, the students should use 1/8 as the fraction for the line plot.
A radioactive isotope is decaying at a rate of 18% every hour. Currently there
are 120 grams of the substance.
Write an equation that will represent the number of grams, y, present after
hours.
=
Can you tell me the answer please
The decay of the radioactive substance can be modeled by the exponential decay function:
y = a(1 - r)^t
where:
- y is the amount of substance present after t hours
- a is the initial amount of substance (in grams), which is 120 grams in this case
- r is the decay rate per hour, which is 18% or 0.18 in decimal form
- t is the time elapsed in hours
Plugging in the values we get:
y = 120(1 - 0.18)^t
Simplifying:
y = 120(0.82)^t
So this is the equation that represents the number of grams, y, present after t hours, given the initial amount of 120 grams and a decay rate of 18% per hour.

If Ethan’s monthly expenses are $1160 and his debt to income ratio is 0. 8, what is his monthly salary?
Ethan's monthly salary is $1450.
Ethan's monthly salary, we can use the debt to income ratio formula, which is calculated by dividing monthly debt expenses by monthly income.
Given:
Monthly expenses = $1160
Debt to income ratio = 0.8
Let's assume Ethan's monthly salary as S.
We can set up the equation using the debt to income ratio formula:
Debt to income ratio = Monthly expenses / Monthly income
0.8 = $1160 / S
To solve for S (monthly salary), we can rearrange the equation:
S = $1160 / 0.8
Dividing $1160 by 0.8 gives us:
S ≈ $1450
Therefore, Ethan's monthly salary is approximately $1450.

The probability of the mouse finding its way out before reaching a dead end or going out in the opening can be estimated by dividing the number of successful outcomes by the total number of trials in the sample.
To create a simulation to determine the probability that the mouse will find its way out before coming to a dead end or going out in the opening, we can follow these steps:
Create a model of the maze in a programming language such as Python.Define the starting position of the mouse as the position on the right side of the maze.Define the exit position of the maze as the position on the left side of the maze.Randomly choose a direction for the mouse to move in (up, down, left or right).Check if the chosen direction leads to a dead end or out of the maze. If it does, return a failure outcome.If the chosen direction leads to a viable path, move the mouse to that position and repeat steps 4-6 until the mouse either reaches the exit or gets stuck in a dead end.Repeat steps 2-6 multiple times to generate a sufficient sample size.Calculate the proportion of successful outcomes (i.e. the mouse finding its way out before reaching a dead end or going out in the opening) from the generated sample.The probability of the mouse finding its way out before reaching a dead end or going out in the opening can be estimated by dividing the number of successful outcomes by the total number of trials in the sample.

Los lados de un triangulo miden, en cm, tres numeros enteros consecutivos. Encuentra la longitud de los tres lados
There are infinitely many possible solutions for the lengths of the three sides of the triangle.
What is triangle?
A triangle is a three-sided polygon with three angles. It is a fundamental geometric shape and is often used in geometry and trigonometry.
If we call x the length of the smallest side, then the other two sides are x+1 and x+2 (since they are three consecutive integers). According to the triangle inequality, the sum of any pair of sides must be greater than the length of the third side.
Therefore, we have:
x + (x+1) > (x+2) (and also x + (x+2) > (x+1) and (x+1) + (x+2) > x)
Simplifying each inequality, we get:
2x + 1 > x + 2 (and also 2x + 2 > x + 1 and 2x + 3 > x)
Which gives:
x > 1
So the smallest side must be greater than 1 cm.
Now, to find the length of the three sides, we can choose any value greater than 1 for x. For example, if we take x=2, then the three sides are:
2 cm, 3 cm, and 4 cm
If we take x=3, then the three sides are:
3 cm, 4 cm, and 5 cm
And so on. Therefore, there are infinitely many possible solutions for the lengths of the three sides of the triangle.

Leg #4-14 km [South]
The cyclist needs to ride approximately 23.21 km in the direction of 23.13° W of North to get back to the starting point.
How to solve for the distanceWe can use trigonometry to find the x and y components.
x3 = 12 * cos(15°) ≈ 11.59 km (east)
y3 = -12 * sin(15°) ≈ -3.10 km (south, hence the negative sign)
Leg #4: 14 km [South]
x4 = 0 km (no east/west movement)
y4 = -14 km (south, hence the negative sign)
Now, let's find the total x and y displacements:
x_total = x1 + x2 + x3 + x4 ≈ 0 + 10 + 11.59 + 0 ≈ 21.59 km
y_total = y1 + y2 + y3 + y4 ≈ 8 + 0 - 3.10 - 14 ≈ -9.10 km

She ran Latex: 4. 5 4. 5 miles the second week and Latex: 6 6 miles the third week. If she continues to increase the length of her runs the same way, will there be enough time left in the training program for her to get up to half-marathon distance?
If she continues to increase the length of her runs the same way, it will not be enough to reach the half-marathon distance of 13.1 miles within the remaining time of the training program.
Sariah has just begun training for a half-marathon, which is 13.1 miles. There are 6 weeks of training runs remaining before the race. In her first week of training, Sariah ran 3 miles. She ran 4.5 miles the second week and 6 miles the third week.
To determine if there is enough time left in the training program for her to get up to half-marathon distance, let's analyze the pattern of her weekly increases in distance:
Week 2 - Week 1 = 4.5 miles - 3 miles = 1.5 miles increase
Week 3 - Week 2 = 6 miles - 4.5 miles = 1.5 miles increase
Sariah is consistently increasing her weekly mileage by 1.5 miles. With 3 weeks of training already completed, she has 3 more weeks to go. Let's see if she can reach the half-marathon distance of 13.1 miles:
Week 4: 6 miles + 1.5 miles = 7.5 miles
Week 5: 7.5 miles + 1.5 miles = 9 miles
Week 6: 9 miles + 1.5 miles = 10.5 miles
After 6 weeks of training, Sariah will have increased her longest run to 10.5 miles. Unfortunately, this is not enough to reach the half-marathon distance of 13.1 miles within the remaining time of the training program.

What is the graph of g?
Answer:
Vertical Compression by factor of 1/4
Step-by-step explanation:
Two methods:
Method 1. Transformations
Method 2. Algebraic input-output tables
Method 1. Transformations
The Main concept of this question is about Transformations of functions -- specifically, multiplying on the outside by a positive number less than 1.
The transformation that occurs when multiplying a function by a positive number on the outside of the function is a vertical stretch or compression.
Positive numbers larger than 1 will stretch it vertically, whereas positive numbers smaller than 1 will compress it vertically.
Therefore, multiplying by 1/4 on the outside, a positive number less than 1, will vertically compress the function down to one-fourth the size.
This means that for g(x), all points on the original function f will have their heights reduced to 1/4 their original height (or depth) -- making all points on g(x) 1/4 their previous distance from the x-axis on the "f" function.
Method 2. Algebraic input-output tables
Observe on the graph three points on the function f:
(0,0), (1,4) and (3,0) --- points on the function "f"In function notation, this means [tex]f(0)=0[/tex], [tex]f(1)=4[/tex], and [tex]f(3)=0[/tex]Using the equation relating f and g, [tex]g(x)=\frac{1}{4}f(x)[/tex], we can find how those points would look like on the new function g(x).
For [tex]f(0)=0[/tex]
[tex]g(0)=\frac{1}{4}[f(0)]\\g(0)=\frac{1}{4}[0]\\g(0)=0[/tex]
For [tex]f(1)=4[/tex]
[tex]g(1)=\frac{1}{4}[f(1)]\\g(1)=\frac{1}{4}[4]\\g(1)=1[/tex]
For [tex]f(3)=0[/tex]
[tex]g(3)=\frac{1}{4}[f(3)]\\g(3)=\frac{1}{4}[0]\\g(3)=0[/tex]
These known points should correctly identify the graph from the possible choices.

Consider the geometric series 1 - x/3 - x^2/9 - x^3/27......
What is the common ratio of the series and for what values of x will the series converge? Determine the function f representing the sum of the series.
The function f representing the sum of the series for x in the interval (-3, 3). Hi! The given geometric series is 1 - x/3 - x^2/9 - x^3/27...
The common ratio of the series is obtained by dividing a term by its preceding term. Let's consider the first two terms:
(-x/3) / 1 = -x/3
Therefore, the common ratio (r) of the series is -x/3.
For a geometric series to converge, the absolute value of the common ratio must be less than 1, i.e., |r| < 1. In this case:
|-x/3| < 1
To find the values of x for which the series converges, we need to solve the inequality:
-1 < x/3 < 1
Multiplying all sides by 3, we get:
-3 < x < 3
So, the series converges for x in the interval (-3, 3).
Now, let's determine the function f representing the sum of the series. For a converging geometric series, the sum S can be calculated using the formula:
S = a / (1 - r)
where a is the first term and r is the common ratio. In this case, a = 1 and r = -x/3. Therefore:
f(x) = 1 / (1 - (-x/3))
f(x) = 1 / (1 + x/3)
This is the function f representing the sum of the series for x in the interval (-3, 3).

S = lim[n → ∞] sn
= lim[n → ∞] (306n^2 + 35n + 306)
= ∞
So unfortunately, the series (n + 16)(n + 18) diverges to infinity and does not have a finite sum.To find the sum S of the series (n + 16)(n + 18), we need to take the limit of the sequence of partial sums as n approaches infinity. So let's first find the formula for the nth partial sum sn:
sn = (1 + 16)(1 + 18) + (2 + 16)(2 + 18) + ... + (n + 16)(n + 18)
= ∑[(k + 16)(k + 18)] (from k = 1 to n)
Using the formula for the sum of squares, we can expand each term in the sum:
(k + 16)(k + 18) = k^2 + 34k + 288
So now we have:
sn = ∑(k^2 + 34k + 288) (from k = 1 to n)
= ∑k^2 + 34∑k + 288n (from k = 1 to n)
= n(n + 1)(2n + 1)/6 + 34n(n + 1)/2 + 288n
= 306n^2 + 35n + 306
Now we can take the limit of sn as n approaches infinity to find S:
S = lim[n → ∞] sn
= lim[n → ∞] (306n^2 + 35n + 306)
= ∞
So unfortunately, the series (n + 16)(n + 18) diverges to infinity and does not have a finite sum.

The Greens bought a condo for $110,000 in 2005. If its value increases at 6% compounded annually, what will the value be in 2020?
Answer:
$264,000
Step-by-step explanation:
PV = $110,000
i = 6%
n = 15 years
Compound formula:
FV = PV (1 + i)^n
FV = 110,000 (1 + 0.06)^15
FV = 110,000 · 2.40(rounded) = $264,000
The diameter of a circle is 2 kilometers. What is the circle's circumference? d=2 km Use 3. 14 for . Kilometers?
The circumference of the circle is 6.28 kilometers if the diameter of the circle is 2 kilometers and assuming the value of π is 3.14 kilometers.
The diameter of the circle = 2 kilometers
The circumference of a circle is calculated by using the formula,
C = π *d
where,
C = circumference of a circle
d = diameter of the circle
π = Constant value = 3. 14 Km
Substituting the above-given values into the equation, we get:
C = π*d
C = 3.14 x 2 km
C = 6.28 km
Therefore, we can conclude that the circumference of the circle is 6.28 kilometers.

A laboratory tested 82 chicken eggs and found that the mean amount of cholesterol was 228 milligrams with a = 19. 0 milligrams. Construct a 95% confidence interval for the
true mean cholesterol content,, of all such eggs.
We can say with 95% confidence that the true mean cholesterol content of all such eggs is between 223.99 milligrams and 232.01 milligrams.
To construct a 95% confidence interval for the true mean cholesterol content of all such eggs, we can use the following formula:
CI = X ± Zα/2 * σ/√n
where:
X = sample mean = 228 milligrams
Zα/2 = the critical value from the standard normal distribution corresponding to a 95% confidence level, which is 1.96
σ = population standard deviation = 19.0 milligrams
n = sample size = 82
Substituting the values into the formula, we get:
CI = 228 ± 1.96 * 19.0/√82
= 228 ± 4.01
= (223.99, 232.01)
Therefore, we can say with 95% confidence that the true mean cholesterol content of all such eggs is between 223.99 milligrams and 232.01 milligrams.

What is an algebraic expression?
An algebraic expression is a mathematical phrase that contains variables, constants, and mathematical operations. It may also include exponents and/or roots. Algebraic expressions are used to represent quantities and relationships between quantities in mathematical situations, often in the context of problem-solving.
To solve the equation:
(-3m^ {5}) (-2m^ {4}) = (-6m^ {9})
We can simplify the left side of the equation by multiplying the terms:
(-3m^ {5}) (-2m^ {4}) = (6m^ {9})
Now we have:
6m^ {9} = (-6m^ {9})
To solve for m, we can divide both sides by 6m^ {9}:
m^ {9} = -m^ {9}
Since the powers of m on both sides are equal, we can simplify to:
2m^ {9} =0
Dividing both sides by 2, we get:
m^ {9} =0
Taking the ninth root of both sides, we get:
m = 0
Therefore, the solution to the equation is m = 0.
