The Elevator’s rate of change is found to be 3 floors per second using the given data.
What is the most basic definition of rate?Rate is the pace at which an object's location changes in any direction. Rate is defined as the ratio of distance traveled to time spent traveling. Speed is classified as a scalar quantity since it has just one direction and no magnitude.What is the speed calculation?Speed (or rate, r) is a scalar number that represents the distance traveled (d) divided by the change in time (t) by the equation r = d/t.
Given: In 40 seconds, an elevator travels from the 124 floor to the 8 floor of a skyscraper. The elevator maintains a constant speed.
We know that,
Rate = Distance/Time
Elevator’s rate of change = (124-8)/40
= 116/40
= 2.9 ≈ 3 floors per second
Therefore, the Elevator’s rate of change is found to be 3 floors per second using the given data.

The amount owed at the end of the 6 years duration is $10865
How to determine the amount owed in six years?The given parameters about the compound interest are
Principal Amount, P = $5300
Interest Rate, R = 8%
Time, t = 6 years
To calculate the amount owed, we make use of the following formula
A = P + CI
Where
Compound interest, CI = P(1 + R)^t - P
So, the equation becomes
A = P + P(1 + R)^t - P
Evaluate the like terms
A = P(1 + R)^t
In this question, the formula is given as
A = P(1 + r/n)^nt
Where
n = 12, i.e compounded monthly
Substitute the known values in the above equation
A = 5300 * (1 + 8%/12)^(6*12)
Express 8% as decimal
A = 5300 * (1 + 0.08/12)^(6*12)
Evaluate the sum
A = 5300 * (1.01)^(6*12)
Evaluate the exponent
A = 5300 * 2.05
Evaluate the product
A = 10865
Hence, the value of the amount after 6 years is $10865

a solid is formed by adjoining two hemispheres to the ends of a right circular cylinder. an industrial tank of this shape must have a volume of 2880 cubic feet. the hemispherical ends cost twice as much per square foot of surface area as the sides. find the dimensions that will minimize the cost.
The dimensions that minimize the cost of building the tank are r ≈ 6.5 ft and h ≈ 26 ft
What do you mean by cost?
The cost is the sum of money that a business spends on the development or manufacturing of goods or services. It excludes the profit margin markup. The sum of money spent to create a good or product, as seen from the seller's perspective, is the cost.The total cost becomes
T = ucSc + 2ucSh
= 2ucπrh + 8ucπr²
We need to eliminate h . The volume from the question gives a way out.
4640 = 4/3πr³ + πr²h
h = 4640/πr² - 4r/3
substitute into the formula for total cost gives, after simplifying
T = 16ucπr²/3 + 9280uc/r²
differentiating with respect to r , we get
dT/dr = 32/3Ucπr - 9280Uc/r²
at extrema
dT/dr = 0
⇒ 32/3Ucπr = 9280Uc/r²
r = ∛870/π ≈ 6.5 ft
To confirm that r is a minimum value, carry out the second derivative test
d²T/dr² = 32Ucπ/3 + 18560/r³
substituting ∛870/π, we get that d²T/dr² > 0 confirming that minimum value
To find h , recall that
h = 4640/πr² - 4r/3
substituting r , we get h ≈ 26.0 ft as the corresponding minimum height.

Last year, Alonzo had 30,00 to invest. He invested some of it in an account that pain 7% simple interest per year, and he invested the rest in an account that paid 5% simple interest per year. After one year, he revived a total of 1680 in interest. How much did he invest in each account?
The amount of money that Alonso has invested in these accounts is given as $9000 and $21000
How to solve for the investmentWe have to represent the percentages as a and b, then multiply 100 at the right hand side of the equation
we would have
7a + 5b = 1680 * 100
7a + 5b = 168000 ---- 1
From the amount that Alonso has to invest we would have
a + b = 30000
where b = 30000 - a ---- 2
We have to put the value of b in equation a
7a + 5(30000 - a) = 168000
7a + 150000 -5a = 168000
7a - 5a = 168000 - 150000
2a = 18000
a = 18000 / 2
= $9000

Matthew's curtain company is making curtains for a local hotel. he wants each curtain to be 36 inches long. at the fabric store, fabric is sold by the foot. if matthew's curtain company wants to make 74 curtains, how many feet of fabric will he need?
Matthew will need 222 feet of fabric to make 74 curtains.
According to the question,
We have the following information:
Required length of each curtain = 36 inches
Total number of curtains to be made = 74
Now, the total length of the fabric needed to make 4 curtains can be found by multiplying length of one curtain by total number of curtains.
So, we have the following expression:
36*74
2664 inches
Now, we will convert this into feet:
1 inch = 1/12 foot
2664 inches = 2664/12 feet

function y = ².
1. vertex (0, 0), point (-2.3)
The graph of the quadratic function y = 0.75x² is given by the image at the end of the answer.
The notation y = 0.75x² is already in vertex form, meaning that the function was vertically compressed by a factor of 3/4 from the original graph.
How to define the quadratic equation?The definition of a quadratic equation with vertex (h,k) is given as follows:
y = a(x - h)² + k.
In which a represents the leading coefficient of the quadratic function.
In this problem the coordinates of the vertex are:
(0,0).
Hence the parameters are:
h = 0, k = 0.
Thus the equation is:
y = ax².
When x = -2, y = 3, hence the leading coefficient is given as follows:
3 = a(-2)²
4a = 3
a = 3/4
a = 0.75.
Hence the equation is:
y = 0.75x².
The multiplication by 0.75 means that the parent function y = x² is vertically compressed by a factor of 0.75.

driving between two towns at 110 kmph instead of 100 kmph saves 9 minutes. what is the distance between the two towns in kilometers?
The distance between the two towns is 165 kilometers
The initial speed = 100 kilometer per hour
Time taken = t hours
We know,
Speed = Distance / Time
Distance = Speed × t
Distance = 100 × t
New speed = 110 kilometer per hours
He saves 9 minutes
9 minutes = 9/60 hours
The time taken = t - 9/60
The distance = 110 × (t - 9/60)
= 110t - 33/2
Then the equation will be
100t = 110t - 33/2
110t - 100t = 33/2
10t = 33/2
t = 33/2 ÷ 10
t = 33/2 × 1/10
t = 1.65 hours
Then the distance = 100 × t
= 100 × 1.65
= 165 kilometers
Hence, the distance between the two towns is 165 kilometers

The following is the 95% confidence interval for the standard deviation of UH students' height: CI = (1.81, 4.028) that is option B is correct.
What is standard deviation?The term "standard deviation" (or "") refers to a measurement of the data's dispersion from the mean. A low standard deviation indicates that the data are grouped around the mean, whereas a high standard deviation shows that the data are more dispersed. The standard deviation gauges how widely the data deviates from the mean. When comparing data sets that may have the same mean but a different range, it is helpful.
Here,
The formula for the standard deviation's confidence interval is given as CI = √[(n - 1)s²/(χ²ₙ ₋ ₁, α/2)], √[(n - 1)s²/(χ²ₙ ₋ ₁, (1 - α)/2)]
Number of participants; n = 14 D F = n - 1 = 14 - 1 = 13
Deviation from the mean; s = 2.5
Significant level; = 1 - 0.95 = 0.05
Confidence level; CL = 95% = 0.95
As a result, using an online Chi-square distribution table, we have:
χ²₁₃, ₀.₀₂₅ = 24.736
(χ²₁₃, ₀.₉₇₅) = 5.01
CI = √[(13 * 2.5²/(24.736)], √[(13 * 2.5²/(5.01)]
CI = (1.81, 4.03) (1.81, 4.03)

The probability that the first is a king, the second a diamond and the third a diamond quiz let is 1/13, 1/4 and 10/52 respectively.
Now, we know that there are 52 cards in the deck of cards, and there are 13 cards of each suits i.e. diamonds, spade, heart and clubs. Also there are 12 face cards in total of the deck.
So, the probability if getting the first card is king :
King is a face card and there are 4 kings in the deck so the probability will be :
P(getting 1st card as king) = 4/52 = 1/13.
The probability of getting the second card a diamond is :
we know that there are 13 cards of the diamond in the deck so the probability will be :
P(getting the diamond card) = 13/52 = 1/4.
Now, lastly the probability if getting the diamond quiz let is :
There are 10 flashcards of the diamonds in the deck, so the probability will be :
P(getting the diamond flashcard) = 10/52.

which characteristic allows a gas to be compressed
Answer:
"Gases are compressible because most of the volume of a gas is composed of the large amounts of empty space between the gas particles. At room temperature and standard pressure, the average distance between gas molecules is about ten times the diameter of the molecules themselves."

You intend to estimate a population mean with a confidence interval. You believe the population to have a
normal distribution. Your sample size is 51.
Find the critical value that corresponds to a confidence level of 95%.
(Report answer accurate to three decimal places with appropriate rounding.)
The critical value will be +- 1.96.
What is critical value?
A crucial value delimits areas of a test statistic's sampling distribution. Both confidence intervals and hypothesis tests take these values into account.
Main body:
sample size is 10.
if you use z-scores, and it appears that you have to, since you don't know the mean or standard deviation of your population, your mean is 0 and your standard deviation is 1.
at 95% confidence level, 100% - 95% is your alpha.
that makes it equal to 5%.
divide that by 2 and you have half your alpha on the left end of the confidence interval and half on the right end.
that makes it 2.5% on each end.
2.5% is the same as .025 in decimal form.
look up a z-score to the left of .025 to get a z-score of -1.959963986 which can be rounded to -1.96.
since the normal distribution is symmetric about the mean,
Therefore your critical z-score is plus or minus 1.96.

Identify the proportional relationship
There is no proportional relationship between the given equations.
What is proportional relationship?
Relationships between two variables where their ratios are equal are known as proportional relationships. The fact that one variable is always a constant value multiplied by the other in a proportionate connection is another way to conceive of them. This parameter is referred to as the "constant of proportionality".
The given equations are,
7x - 2 = y
y = 2x + 4
y = 5x
y + 1 = 3x
These equations can be written as,
y = 7x - 2
y = 2x + 4
y = 5x
y = 3x - 1
Now consider the following table,
x y y/x
7 1 1/7
2 1 1/2
5 1 1/5
3 1 1/3
From above we can see that none of the ratio are equal, all ratios are different.
Hence, none of the given equations having proportional relationship.
