Answer:
The fifth salary = $49,000
Step-by-step explanation:
Let x be the fifth salary
Total salary = $36,000, + $45,000 + $28,000 + $32,000 + x
= $141,000 + x
The average of 5 salaries is $38,000
Total = Average x number of elements
= 38000 x 5 = 190,000
Equating the two totals
141,000 + x = 190,000
Subtract 141, 000 from both sides
x = 190,000 - 141, 000
x = $49,000
So the fifth salary = $49,000
You and your friend just got new puppies. Your puppy, Max, currently weighs 5 pounds and is expected to gain 1 pound per week. Your friend's puppy, Ruby, currently weighs 8 pounds and is expected to gain 0.5 pounds per week. After how many weeks will the puppies weigh
Two puppy's Max and Ruby will have equal weight after 6 weeks
What is an arithmetic sequence?In the arithmetic sequence the common difference remains constant between any two consecutive terms. In this sequence we can get the next term by adding one fixed value which is known as a common difference. It is also known as arithmetic progression(AP).
Formula for any nth term in AP,
T = a + nd
d = T₂-T₁
Where, a is first term , n is nth term and d is common difference
Given that,
Two puppy's
Max, currently weighs 5 pounds and is expected to gain 1 pound per week,
Ruby, currently weighs 8 pounds and is expected to gain 0.5 pounds per week
The number of weeks when both will have equal weight = ?
Suppose, it number of weeks = n
It can be solved by using concept of arithmetic sequence,
a₁ = 5 pounds
d₁ = 1 pound per week
Tₙ = 5 + 1xn = 5 + n
a₂ = 8 pounds
d₂ = 0.5 pounds per week
Tₙ = 8 + 0.5xn = 8 + 0.5n
Both should be equal,
5 + n = 8 + 0.5n
0.5n = 8 - 5
n = 6
Hence, after 6 weeks they will have same weight

if the owner decides to increase the living room dimensions by 20%, what is the new length and width of the living room floor?
The new length and width of the living room would be 20% greater than the original length and width.
A percentage is a figure or ratio stated as a fraction of 100 in mathematics. The percent symbol, "%," is commonly used, however the abbreviations "pct.", "pct," and sometimes "pc" are also used.
A percentage is a number with no dimensions; it has no unit of measurement.
To increase the length and width of a room by 20%,
We need to add 20% of the original length and width to the original values.
If the original length and width of the living room are L and W respectively, the new dimensions would be:
New length = L + 0.20 * L = 1.20 * L
New width = W + 0.20 * W = 1.20 * W

How should a writer address opposing views in an argument?
The writer should ignore opposing views so as to not bring attention to conflicting information.
The writer should mention opposing views to point out the flaws of the people who believe in them.
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.

The time it takes to travel to a location varies inversely to the speed traveled. It takes 4 hours driving at an average speed of 55 miles per hour to reach a location. To the nearest tenth of an hour, how long will it take to reach the same location driving at an average speed of 50 miles per hour?
Time it will take to reach the same location driving at an average speed of 50 miles per hour, 4.4 hour
What is the relation between time, distance & speed ?The distance covered by the object is equal to the product of the speed at which the object is moving and time taken for covering the distance.
Distance = Time × Speed
Given that,
The time it takes to travel to a location varies inversely to the speed traveled,
Time = 4 hours
Average speed = 55 miles per hour
If average speed = 50 miles per hour
then time = ?
First, it is required to calculate distance covered,
Distance = Time × Speed
= 4 x 55
= 220 miles
Now, when average speed is 50 miles per hour,
Distance = Time × Speed
Speed = Distance/Time
= 220/50
= 4.4 hour

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

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.

A cylinder has a height of 9 yards and a diameter of 34 yards. What is its volume? Use ≈ 3.14 and round your answer to the nearest hundredth.
The volume of the cylinder is given by the equation V = 8,167.14 yards³
What is a Cylinder?A cylinder is a three-dimensional shape consisting of two parallel circular bases, joined by a curved surface. The center of the circular bases overlaps each other to form a right cylinder. The volume of a cylinder is
Volume of Cylinder = πr²h
Surface area of cylinder = 2πr ( r + h )
where r is the radius of the cylinder
h is the height of the cylinder
Given data ,
Let the volume of the cylinder be represented as V
Now , the equation will be
The height of the cylinder h = 9 yards
The diameter of the cylinder d = 34 yards
So , the radius of the cylinder r = d/2 = 17 yards
And , Volume of Cylinder = πr²h
Substituting the values in the equation , we get
Volume of Cylinder = ( 3.14 ) x ( 17 )² x 9
On simplifying the equation , we get
Volume of Cylinder = ( 3.14 ) x 2,601
Volume of Cylinder = 8,167.14 yards³

15% wrapped = 30
20% not oatmeal = 40
30 wrapped could all be not oatmeal.
there are 200 pieces of cookies in a bag.
15% are wrapped.
this means that .15 * 200 = 30 are wrapped.
80% of the cookies are oatmeal.
this means that .8 * 200 = 160 are oatmeal.
this also means that .2 * 200 = 40 are not oatmeal.
Unless I'm misreading the situation, it is entirely possible that none of the wrapped cookies are oatmeal as there are more than 30 cookies that are not oatmeal and 30 are wrapped.
It would be a different situation if cookies were chosen at random and then wrapped.
Without even glancing at the cookies, you would choose 30 for wrapping.
The likelihood that you would choose an oatmeal cookie is.
.8 given that oats make up 80% of the batch of cookies.
the likelihood that you would choose an oatmeal-free cookie. 2 since just 20% of the batch's cookies contains oats.
The likelihood of it happening if you pick at random is: The fewest number of oatmeal cookies that are wrapped would still be 0, and the probability of that happening is:
c(40,30) / c(200,30) = 2.069..... * 10^-27
bottom line is that it is possible to get 0 oatmeal cookies wrapped if you pick cookies out of the batch randomly, but the probability that they will all not be oatmeal is extremely small.
the probability that all the wrapped cookies are not oatmeal when you pick the cookies out of the batch randomly is 2.06907098 * 10^-27
that's a very small probability.
it's so small that if you rounded the answer to 26 decimal digits, it would be equal to 0.
but it's not zero, and therefore it is possible that you could get zero wrapped cookies that are oatmeal if you picked them out of the batch randomly without looking at them.
if you looked, and you could tell the difference, then there's no question that you could pick 30 cookies to be wrapped that are not oatmeal since you would have 40 to pick from.
that's my take.
