Montana decided to start his ball from the second diamond from the left along the bottom rail. He is planning to aim at the third diamond from the top right. If he hits the ball sufficiently hard, will the ball eventually reach a pocket? If so, show the path of the ball. Explain the steps used to solve the problem and write a concluding statement
Answer:
To determine whether the ball will eventually reach a pocket, we need to determine if the ball will collide with any other balls or obstacles on the way to its target. If there are no obstacles, and the ball has enough force and the correct trajectory, it will reach the target pocket.
To show the path of the ball, we can draw a straight line connecting the starting position and the target pocket. This line represents the trajectory of the ball if it is not obstructed by any other balls or obstacles.
In conclusion, without any obstacles in the way, if Montana hits the ball with enough force and the correct trajectory, the ball will reach the target pocket. It is important to consider any potential obstacles or interference when planning a shot in billiards.

Consider two investments, one earning simple interest and one earning compound interest. If both start with the same initial deposit (and you make no other deposits or withdrawals) and earn the same annual interest rate, how will the balance in the simple interest account compare to that of the compound interest?
A. The account with simple interest will have the same balance as the account with compound interest because the annual interest rates are equal.
B. The account with simple interest will have the same balance as the account with compound interest because the initial deposits are equal.
C.The account with simple interest will have a greater balance than the account with compound interest because compound interest is interest paid only on the original investment.
D.The account with simple interest will have a smaller balance than the account with compound interest because the more times interest is applied to an investment, the smaller the balance.
E. The account with simple interest will have a smaller balance than the account with compound interest because compound interest is interest paid both on the original investment and on all interest that has been added to the original investment.
The account with simple interest will have a smaller balance than the account with compound interest because compound interest is interest paid both on the original investment and on all interest that has been added to the original investment. (option F)
What is simple and compound interest?An account that earns a simple interest grows at a linear rate while an account that earns a compound interest grows at an exponential rate.
Let us assume the following:
Amount invested = $1000
Interest rate = 5%
Number of years = 5 years
Future value of the account that earns a simple interest in 5 years = amount invested + simple interest
Simple interest = amount invested x time x interest rate
$1000 x 0.05 x 5 = $250
Future value in 5 years = $1000 + $250 = $1250
Future value of the account that earns a compound interest :
Future value = amount invested x (1 + interest rate)^number of years
= 1000 x (1 + 0.05)^5
= 1000 x 1.05^5

How to determine the slant heightFrom the question, we have the following parameters that can be used in our computation:
Volume = 72π
Diameter = 6
The volume of a cone is
V = 1/3πr^2h
Where
r = 6/2 = 3
So, we have
1/3π * 3^2h = 72π
This gives
3h = 72
Divide by 3
h = 24
The slant height is then calculated as
l = √(h² + r²)
So, we have
l = √(24² + 3²)
Evaluate
l = 24.19
Hence, the slant height is 24.19 units

The writer should include an explanation and evidence as to why the counterclaim is incorrect.
The writer should give equal attention and value to opposing views, including using evidence.
Answer:
The writer should give equal attention and value to opposing views, including using evidence. This helps to strengthen the argument by acknowledging and refuting counterarguments. It also demonstrates to the reader that the writer has considered multiple perspectives and is able to effectively argue their position. By giving equal attention to opposing views, the writer shows that their argument is well-reasoned and credible.
Step-by-step explanation:
When making an argument, it's important to consider and address any opposing views that exist. Giving equal attention to opposing views means acknowledging the validity of these views and providing evidence to refute them. This helps to strengthen the argument by showing that the writer has considered multiple perspectives and has a solid understanding of the issue at hand. It also demonstrates to the reader that the argument is well-reasoned, credible, and based on evidence.
On the other hand, ignoring opposing views, or attacking those who believe in them, weakens the argument and undermines the writer's credibility. If a counterargument is not addressed, the reader may assume that the writer is not aware of it or cannot effectively defend their position. By giving equal attention to opposing views and refuting them with evidence, the writer is able to make a stronger argument and persuade the reader of their point of view.
Answer:
The writer should use facts that can be verified to address and disprove opposing viewpoints.

the blenders produced by a company have a normally distributed life span with a mean of 8.2 years and a standard deviation of 0.8 years. the company is willing to have a warranty that replaces at most 6% of their blenders sold. what is the longest a blender can last and still be in the lowest 6% of life spans?
The longest a blender can last and still be in the lowest 6% of life spans is 7.96 years.
The longest a blender can last and still be in the lowest 6% of life spans is calculated by using the inverse normal distribution formula. This formula is P(X ≤ x) = 1 - P(X > x). The X is the longest a blender can last and P(X ≤ x) is 6%. First, we need to calculate the z-score for 6%. This can be done by P(X ≤ x) = 0.06 and using the z-score formula z = (x - μ) / σ , where μ is the mean and σ is the standard deviation. Substituting the values into the equation, we get z = 0.06 = (x - 8.2) / 0.8. Solving for x gives us x = 7.96. Therefore, the longest a blender can last and still be in the lowest 6% of life spans is 7.96 years.

Suppose that the mean retail price per gallon of regular grade gasoline in the United States is $3.45 with a standard deviation of $0.20 and that the retail price per gallon has a bell-shaped distribution. (a) What percentage of regular grade gasoline sold between $3.25 and $3.65 per gallon? % (b) What percentage of regular grade gasoline sold between $3.25 and $3.85 per gallon? % (c) What percentage of regular grade gasoline sold for more than $3.85 per gallon? %
The required percentage of regular grade gasoline are;
a) 34%
b) 95.5%
c)4.5%
How we determine the percentage of regular grade gasoline?(a) To determine the percentage of regular grade gasoline sold between $3.25 and $3.65 per gallon, we need to find the proportion of the data that falls within this range. Assuming a bell-shaped distribution, we can use the standard deviation and mean to find the z-scores for these two prices, and then look up the cumulative probability in a standard normal table.
$3.25$ is $1$ standard deviation below the mean and $3.65$ is $0.5$ standard deviation above the mean.
Using a standard normal table, we find that approximately 68% of the data falls within one standard deviation of the mean, and approximately 34% falls between $-0.5$ and $0.5$ standard deviations.
Therefore, approximately 34% of regular grade gasoline is sold between $3.25 and 3.65 per gallon.
(b) To find the percentage of regular grade gasoline sold between $3.25 and $3.85 per gallon, we need to find the cumulative probability for the range $3.25$ to $3.85$.
$3.85$ is $1.5$ standard deviations above the mean.
Using a standard normal table, we find that approximately 95.5% of the data falls within $1.5$ standard deviations of the mean.
Therefore, approximately 95.5% of regular grade gasoline is sold between $3.25 and $3.85 per gallon.
(c) To find the percentage of regular grade gasoline sold for more than $3.85 per gallon, we need to find the cumulative probability for values greater than $3.85$.
Using a standard normal table, we find that approximately 100% - 95.5% = 4.5% of the data falls above $1.5$ standard deviations from the mean.
Therefore, approximately 4.5% of regular grade gasoline is sold for more than $3.85 per gallon.
