Answer:
Step-by-step explanation:
2 l + 2w = 34 ⇔ l + w = 17 ⇒ l = 17 - w ..... (1)
l w = 66 ..... (2)
(1) ----> (2)
(17 - w) w = 66
w² - 17w + 66 = 0 ⇔ (w - 6)(w - 11) = 0
w = 6 cm
l = 11 cm

Find the dimensions of a cylinder of volume 17 m3 of minimal cost if the top and bottom are made of material that costs twice as much as the material for the side.
Answer:
The answer is below
Step-by-step explanation:
The volume of the cylinder with radius (r) and height (h) is given as:
Volume = πr²h
17 = πr²h
h = 17 / πr²
Let k represent the cost of the side and 2k the cost of the bottom.
The area of the side = 2πrh, hence the cost of the side = k(2πrh)
The area of the top and bottom = 2πr², hence the cost of the top and bottom = 2k(2πr²)
The total cost (T) = cost of side + cost of the top and bottom
T = k(2πrh) + 2k(2πr²)
T = 2kπ(rh + 2r²)
Put h = 17/πr²
T = 2kπ (r×17/πr² + 2r²)
T = 2kπ(17/πr + 2r²)
The minimal cost is at dT/dr = 0
[tex]\frac{dT}{dr} =0=\frac{d}{dr} [2k\pi(\frac{17}{\pi r} +2r^2)]\\\\4r-\frac{17}{\pi r^2} =0\\\\4r=\frac{17}{\pi r^2}\\\\r^3=\frac{17}{4\pi }=1.35\\\\r=\sqrt[3]{1.35}\\\\r=1.1\ m\\\\h=\frac{17}{\pi r^2} =\frac{17}{\pi (1.1)^2} \\\\h=4.42\ m[/tex]

What is the sum of the interior angles of a polygon that has 10 sides?
Answer:
Hope this helps :D
So, the sum of the interior angles of a decagon is 1440 degrees. All sides are the same length (congruent) and all interior angles are the same size (congruent). To find the measure of the angles, we know that the sum of all the angles is 1440 degrees (from above)... And there are ten angles
Answer:
I think the answer is 1440
Step-by-step explanation:
A polygon with 10 sides a decagon ,and the sum of the interior angles is 1440 degrees.

B.
The relationship is linear and non-proportional.
C.
The relationship is non-linear and proportional.
D.
The relationship is non-linear and non-proportional.
Answer: A
Step-by-step explanation: The line is linear as it changes at a constant rate which means it’s also proportional as proportional means as x changed so does y.

For Normal distribution with mean u 400
and standard deviation o = 100 find probability
that x is less than 535: P(x < 535)
Answer:
Step-by-step explanation:
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the weights of a population, and for this case we know the distribution for X is given by:
Where and
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
And we can find this probability using the normal standard table or exce:

Victor wants to conduct a survey to find how much time the students of his school spent playing football. Which of the following is an appropriate statistical question for this survey? Who plays football on weekends? Who plays football the most on Mondays? How many hours per week do you play football? How many students play football for one hour every day?
Answer:
The question "How many hours per week do you play football" is most appropriate.
Step-by-step explanation:
He is trying to find how much time students play football so this question will help him get the data of how many hours they play.
Answer:
The answer is "How many hours per week do you play football?"Step-by-step explanation:
We can figure out that "How many hours per week do you play football?" is the answer because the question is asking of you "Which of the following is an appropriate statistical question for this survey?" the key words in question is "statistical, and appropriate". For the first half of the question it's telling you "Victor wants to conduct a survey to find how much time the students of his school spent playing football." The key words in this first half of the question is "how, much, time, and spent" the answer that says "How many hours per week do you play football?" Has the key words "how, many, hours, per week" these key words it's equal to the key words in the second half of the question "How=How, Many=Many, Hours=Time Per Week=The Time Spent".
So the answer would be "How many hours per week do you play football?".I NEED HELP PLEASE HELP ME

A sample of 5 months of sales data provided the following information:
Month 1 2 3 4 5
Units Sold 97 120 88 97 93
Required:
a. Develop a point estimate of the population mean number of units sold per month (to 1 decimal).
b. Develop a point estimate of the population standard deviation (to 2 decimals).
Answer:
a. 99
b. 12.31
Step-by-step explanation:
a. Estimate of the population mean number of units sold per month
n = Number of Data Values = 5
Sum of Data Values = Σxi =97 + 120 + 88 + 97 + 93 = 495
Sample Mean = X = Σxi/n = 495 / 5 = 99
The population mean number of units sold per month is 99
b. Estimate of the population standard deviation
Month Data (x) X x - X (x - X)^2
1 97 99 -2 4
2 120 99 21 441
3 88 99 -11 121
4 97 99 -2 4
5 93 99 6 36
Sum of deviation squared 606
s^2 = Sample Variance = Σ(xi - X)2/(n - 1)
Sample Variance = 606/4 = 151.5
Sample Standard Deviation = √Sample Variance
Sample Standard Deviation = √151.5
Sample Standard Deviation = 12.30853362509117
Sample Standard Deviation = 12.31
The point estimate of the population standard deviation is 12.31
