a manufacturer of banana chips would like to know whether its bag filling machine works correctly at the 420 gram setting. is there sufficient evidence at the 0.01 level that the bags are underfilled? based on a 37 bag sample, the manufacturer fails to reject the null hypothesis. what is the conclusion?
The conclusion is that the bag filling machine appears to be working correctly at this setting.
Based on the information provided, the manufacturer conducted a hypothesis test to determine if the bags are underfilled at the 420 gram setting. The null hypothesis (H0) is that the bags are not underfilled, while the alternative hypothesis (H1) is that the bags are underfilled.
Since the manufacturer failed to reject the null hypothesis at the 0.01 level of significance, this means that there is not enough evidence to support the claim that the bags are underfilled at the 420 gram setting. In other words, the bag filling machine appears to be working correctly at this setting.
It's important to note that the conclusion may change if the sample size or the level of significance is different. Additionally, other factors such as the accuracy of the measuring device used or the consistency of the banana chips themselves may also impact the results.

Use the shell method to write and evaluate the definite integral that represents the volume of the solid generated by revolving the plane region about the y-axis.
y = x^3/2
y = 27
x = 0
Volume of solid generated by revolving the plane region about the y-axis is [tex]\pi \left(\frac{1392}{7}\right)[/tex]
What do you understand by Shell method?The shell method formula is used to find the volume of a solid of revolution, formed by rotating a region about a line that is parallel to one of its sides.
The formula for the shell method is V = 2π* ∫r(x)h(x) dx where V is the volume of the solid, r(x) is the distance between the axis of revolution and the curve being rotated and h(x) is the height of the shell at x.
The shell method can be used when the region is more easily described by an equation in one variable. In contrast, the disk/washer method is used when the region is more easily described by an equation in two variables.
It is a powerful tool for solving many types of problems in calculus, physics and engineering. The shell method formula helps to determine the volume of a solid of revolution, which is an important concept in various fields of study.
Given:
y = [tex]x^\frac{3}{2}[/tex]
y = 27
x = 0
Shell method:
V = [tex]2\pi \int\limits_c^d p(y)h(y) dy[/tex]
Then the volume of a solid is
V = [tex]2\pi \int\limits_0^4x(27 - x^\frac{3}{2})dx[/tex]

Amy used her first 2 tokens at Glimmer Arcade to play a game of Roll-and-Score. Then she
played her favorite game, Balloon Bouncer, over and over until she ran out of tokens. Balloon
Bouncer costs 3 tokens per game, and Amy started with a bucket of 35 game tokens.
Which equation can Amy use to find how many games of Balloon Bouncer,
she played
Answer:
11
Step-by-step explanation:
Let's call the number of games of Balloon Bouncer that Amy played as "x".
Amy started with 35 tokens and used 2 for Roll-and-Score, so she had 35 - 2 = 33 tokens left.
Each game of Balloon Bouncer costs 3 tokens, so the total number of tokens used for Balloon Bouncer games is 3x.
Therefore, the equation to find the number of games Amy played is:
33 = 3x
Solving for x, we get:
x = 11
So Amy played 11 games of Balloon Bouncer.

Jonathan rides his bicycle at a velocity of 12 m/s East. He
comes to a hill and over the next 23 seconds, his velocity
decreases to 5 m/s East. What is Jonathan's acceleration?
Jonathan's acceleration is -0.3043 m/s² East, which means he is slowing down.
What is Acceleration?Acceleration is the rate of change of the velocity of an object with respect to time.
Jonathan's initial velocity, u = 12 m/s East
His final velocity, v = 5 m/s East
The time taken, t = 23 seconds
We can use the formula for acceleration:
a = (v - u) / t
Substituting the given values, we get:
a = (5 m/s - 12 m/s) / 23 s
a = -7 m/s / 23 s
a = -0.3043 m/s^2 East
Therefore, Jonathan's acceleration is -0.3043 m/s² East, which means he is slowing down.

Answer:
1. $1900
2. $9
Step-by-step explanation:
Part a:
‘If she doesn’t sell any copies of History is Fun’ means x = 0:
[tex]y = 1900 + 9(0)[/tex]
∴ y = Melissa’s total pay = $1900
Part b:
Rearranging the equation:
[tex]y = 9x + 1900[/tex]
∴m = slope of equation = positive 9
c = y-intercept = 1900
The shape of the graph would be increasing or ascending. And since the Number of copies (x) can never be negative, this means that the amount of pay CANNOT be less than $1900. The amount of $1900 is her minimum pay
The value of m for this equation indicates the change in Melissa’s total pay for every copy she sells.
∴Change in Melissa’s total pay = 9 dollars
Linette and Ruth breed poodles as a hobby. They sold half of the puppies and half a puppy from the latest litter to the local pet shop. Then they sold half of the puppies that were left in the litter and half a puppy to the poodle palace. Then they decided to give the one remaining puppy to their friend Grace. How many puppies were originally in the litter
There were originally 10 puppies in the litter, as of the given condition.
What are equation models?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Here,
We can represent the number of original puppies as "x", and the sequence of events can be represented as:
Sold half of the puppies, so they have x/2 left - 1 sold to the local pet shop.
Sold half of the remaining puppies, so they have (x/2 - 1)/2 left sold to poodle palace.
One puppy was given to Grace, so they have ((x/2 - 1)/2- 1 = x - 2 / 4 - 1 remaining.
Since they are left with x - 2 / 4 - 1 puppies in the end, we can set this equal to 1 (the remaining puppy given to Grace), and solve for x:
x - 2 / 4 - 1 = 1
x - 2 = {1 + 1} * 4
x = 8 + 2
x = 10
Therefore, there were originally 10 puppies in the litter.

In any set of positive integers the replacement of a set of three 2s with a set of two threes will not change the sum
The statement is incorrect. The replacement of three 2s with two threes will change the sum.
For example, consider the set {2, 2, 2}. The sum of this set is 6. However, if we replace three 2s with two threes, the new set becomes {3, 3}, and its sum is 6, which is different from the original sum. Hence, replacing a set of three 2s with a set of two threes does change the sum. An integer is a whole number that can be positive, negative, or zero. Integers are numbers that don't have any fractional or decimal component. Some examples of integers are: -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, and so on.

How does the distance change during the last section of tom’s journey? What does this mean? Explain your reasoning
The distance is decreasing with time meaning that the object is going back to the starting point.
What does it mean when distance decreases with time?When distance decreases with time, it means that the object is moving towards its starting point or moving in the opposite direction from its initial position. In other words, the object is moving backwards or reversing its direction of motion.
Distance is a measure of the total amount of ground covered by an object in motion, while time is a measure of how long it takes the object to cover that distance. If the object is moving towards its starting point, it means that it is covering less and less distance over time, or the distance it covers is decreasing.

c) The absolute value function reflected across the x axis stretched vertically by 5 units shifted left 4 units and up 6 units is y₃ = -5 | x₃ + 4 | + 6
How does the transformation of a function happen?The transformation of a function may involve any change.
Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs), etc.
If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:
Horizontal shift (also called phase shift):
Left shift by c units: y=f(x+c) (same output, but c units earlier)
Right shift by c units: y=f(x-c)(same output, but c units late)
Vertical shift:
Up by d units: y = f(x) + d
Down by d units: y = f(x) - d
Stretching:
Vertical stretch by a factor k: y = k × f(x)
Horizontal stretch by a factor k: y = f(x/k)
Given data ,
a) The absolute value function reflected across the x axis and shifted up 2 units is y₁
The absolute value function is y₁ = | x₁ |
when reflected over x axis , the new function is
