The total differential to estimate the maximum error in the calculated volume of the cylinder is 200.96.
The base radius of a right circular cylinder are measured as 8 cm.
The height of a right circular cylinder are measured as 16 cm.
The possible error in measurement of as much as 0.2 cm each.
We have to calculate the maximum error in the calculated volume of the cylinder.
The formula of volume of cylinder is:
V = πr^2h
The value of dr = 0.2 and dh = 0.2. So;
dV(max) = ∂V/∂r dr + ∂V/∂dh dh
dV(max) = ∂(πr^2h)/∂r dr + ∂(πr^2h)/∂dh dh
On differentiating
dV(max) = 2πrh dr + πr^2 dh
r = 8 cm, π = 3.14 and h = 16 cm.
Now putting the value
dV(max) = 2×3.14×8×16×0.2 + 3.14×(8)^2×0.2
dV(max) = 160.768 + 40.192
dV(max) = 200.96

question 8in all segments, how many orders were placed in one quarter of the year but shipped in the next quarter (for example, an order in which order date = qtr1 2009 and ship date = qtr2 2009)?
The number of orders placed in one quarter of the year and shipped in the next quarter will vary depending on the segment. To determine the exact number, you would need to analyze the data from each segment separately.
To determine the number of orders placed in one quarter of the year but shipped in the next quarter, you will need to analyze the data from each segment separately. Begin by extracting the data from the segment you are interested in and sorting it by order date and ship date. For example, if you are interested in orders placed in Q1 2009 and shipped in Q2 2009, you will need to identify all orders with an order date in Q1 2009 and a ship date in Q2 2009. Once you have identified these orders, you can count them up to determine the total number of orders in the segment that fit this criteria. You can then repeat this process for the other segments to determine the total number of orders placed in one quarter of the year but shipped in the next quarter across all segments.

Brenda plans to reduce her spending by $70 a month. What would be the future value of this reduced spending over the next 12 years? (Assume an annual deposit to her savings account and an annual interest rate of 6 percent.) Use Exhibit 1-B. (Round FVA factor to 3 decimal places and final answer to 2 decimal places.)
Please show me how to figure this out using a financial calculator and the inputs I would put into excel please.
If Brenda plans to reduce her spending by $70 a month, the future value of this reduced spending over the next 12 years is $14710.5.
We are given that Brenda will be saving $70 every month for a period of 12 years.
So, the future value of the annuity formula will be used for the calculation of future value.
Future value = R [( (1 + i)^n - 1 ) / i], where R is the regular payment, i is the interest rate and n is the number of payments
Here R = monthly amount to be saved = $70
i = interest rate = 6/12 = 0.5%
n = Number of payments = 12 x 12 = 144 months
Future value=70 [( (1+0.5%)^144 - 1) / 0.5%] = $14710.5
Hence, the future value of this reduced spending over the next 12 years is $14710.5.

a company has 30 different people that work for it. how many different groups of 4 people could they make to send to a job site?
The number of different groups of 4 people that a company could send to a job site, which is 27,720.
In the context of this question, a company has 30 people and wants to send 4 people to a job site.
To find out how many different groups of 4 people they could make, we need to use the concept of permutation.
To find the number of permutations, we use the formula nPk, where n is the total number of objects (30 in this case) and k is the number of objects we want to arrange (4 in this case).
So, the number of permutations will be
=> 30P4 = 30!/(30-4)!.
This simplifies to
=> 30!/(26!) = 27,720.
Therefore, the company has 27,720 different groups of 4 people that they could send to a job site. This means that they can send 27,720 different combinations of 4 people from their 30 employees to a job site.

The perimeter of a rectangle is 96 cm. if the ratio of the length to width is 7 : 5, find the dimensions of the rectangle
Salut/Hello!
Answer: w = 20 cm and l = 28 cm
Step-by-step explanation:
l - length
w - width
P - perimeter
/ - fraction line
=> - results
we know that P = 2 x (l + w)
we also know that our ratio is l/w = 7/5
l/w = 7/5 => l = 7/5 x w
so now we can go back to the perimeter and replace l
96 = 2 x (7/5 x w + w)
96 = 2 x (7/5 x w/1 + w) Why w/1? - We can't multiply unless w is also in a fraction, so we put it as w/1
96 = 2 x (7w/5 + w)
96 = 2 x (7w/5 + w/1) and we amplify w/1 with 5
96 = 2 x (7w/5 + 5w/5)
96 = 2 x 12w/5
48 = 12w/5
48/1 = 12w/5
48 x 5 = 12w
240 = 12w
w = 20 cm
with that we can find l
96 = 2 x (l + 20)
48 = l + 20
l = 48 - 20
l = 28 cm

How to determine the solution to the systemFrom the question, we have the following parameters that can be used in our computation:
2y = 6
y = -15
Since these are two different equations with the same variable, y, we can use substitution to find a solution.
Starting with the second equation, y = -15, we can substitute this value into the first equation:
2y = 6
2(-15) = 6
-30 = 6
This equation is false, meaning there is no solution for y that satisfies both equations.

A continuous random variable X has a PDF f(x) = ax + X^2 for 0<=x<=1. What is the probability that X is between 0.5 and 1?
A. 15/24
B.17/24
C. 19/24
D. 21/24
The probability that X is between 0.5 and 1 is (C) 19/24.
The probability that X is between 0.5 and 1 can be found by calculating the definite integral of the PDF f(x) over the interval [0.5, 1]:
P(0.5 <= X <= 1) = ∫f(x)dx from 0.5 to 1
Given the PDF f(x) = ax + X^2 for 0<=x<=1, we can evaluate this definite integral as:
P(0.5 <= X <= 1) = ∫(ax + X^2)dx from 0.5 to 1
= [ax^2/2 + x^3/3] from 0.5 to 1
= (1.5a + 1/3) - (0.5a + 0.125)
= (1 + 1/6) - (0.5 + 1/8)

If the area of a rectangle can be repreented by (x^2-5x-14), what two expreion could repreent the dimenion of the rectangle?
The two expressions that could represent the dimension of the rectangle are x + 2 and x - 7
The area of a rectangle can be represented by the product of its length and width. The formula for the area is given by:
A = l x w
where A is the area, l is the length and w is the width.
If the area is given by the expression x^2 - 5x - 14, then the two expressions for the dimensions can be determined by getting the factors of the expression.
x^2 - 5x - 14 = (x + 2)(x - 7)

The rate at which the area of the circle is increasing when the radius is 7 m is 527.52 m^2.
We already know that the area of a circle can easily be calculated using the formula -
= A = π(r^2)
So, in order to find out the rate at which it increases, we have to -
= dA/dt = dπ(r^2)/dt
= dA/dt = dπ(r^2)/dr × dr/dt
= dA/dt = 2πr × dr/dt
It has been mentioned that the value of dr/dt is 12 m/s.

The mean of the sample size of 25 would fall between 68 and 72 68% of the time.
68% Expect Mean IntervalUsing the 68-95-99.7 rule, if a variable is normally distributed with mean μ and standard deviation σ, then:
68% of the data falls within 1 standard deviation of the mean (μ - σ to μ + σ)95% of the data falls within 2 standard deviations of the mean (μ - 2σ to μ + 2σ)99.7% of the data falls within 3 standard deviations of the mean (μ - 3σ to μ + 3σ)Given that the mean of the exam scores is 70 and the standard deviation is 10, the range of 68% of the data falls between 60 and 80.So, 100% - 68% = 32% of the data falls outside this range.Since the interval we are interested in (68 to 72) falls within the 68% of the data that falls within 1 standard deviation of the mean, it means that 100% - 32% = 68% of the data falls within this interval.

Write an exponential equation in the form y = a(b) that can model the number of campers, y, x years after the camp opened. Use whole numbers, decimals, or simplified fractions for the values of a and b.
The number of campers is y = 650(676/650)^x
What is exponential equation ?
Exponential equations are equations in which variables occur as exponents.
An exponential equation in the form y = a(b)^x can be used to model the number of campers, y, x years after the camp opened. Let's use x = 0 for the first year the camp opened (last year) and x = 1 for this year.
Then, we have:
y = a(b)^0 = 650 (when x = 0)
y = a(b)^1 = 676 (when x = 1)
We can use these two points to solve for the values of a and b.
First, we'll use the first equation to solve for a:
a = 650
Next, we'll use the second equation to solve for b:
676 = 650(b)^1
676/650 = (b)^1
b = 676/650
So, the exponential equation in the form y = a(b)^x that can model the number of campers is:

find the number of revolutions taken by a road roller whose lsa is 32cm² to level a play ground of area 6400m²
Answer:
the number of revolutions that are required to level the playground is 194 revolutions
Step-by-step explanation:
We know that LSA, that is lateral surface area of a cylinder is the area of a rectangular sheet, which when spread onto the ground, covers the area equal to the LSA of the cylinder.
Hence, area covered by the roller in one revolution = area of LSA of cylinder = 32 cm².
Now, to cover the are of 6200 cm²,
the number of revolutions required = Total area of the playground/ LSA of the cylinder = 6200/32 = 193.75 = 194
Hence the number of revolutions that are required to level the playground is 194.
