An elementary school is creating a rectangular garden on the side of the school building. The school has raised money to purchase 1000 feet of fence. In order to maximize the area they are using the building for one side and therefore need to use the fencing for the other three sides of the garden. Find the dimensions the school should use to maximize the area of the garden.

Answers

Answer 1

Answer:

[tex]Length = 500ft[/tex]

[tex]Width = 250ft[/tex]

Step-by-step explanation:

Given

[tex]P = 1000[/tex] --- perimeter

Required

The dimensions that maximize the area

Let

[tex]L \to Length[/tex]

[tex]W \to Width[/tex]

Such that:

[tex]P = L + 2W[/tex] ---- Because one side is from the school building

This gives:

[tex]L + 2W = 1000[/tex]

Make L the subject

[tex]L = 1000 - 2W[/tex]

The area is then calculated as:

[tex]A= L * W[/tex]

Substitute: [tex]L = 1000 - 2W[/tex]

[tex]A= (1000 - 2W) * W[/tex]

Open bracket, then set A to 0

[tex]A = 1000W - 2W^2[/tex]

[tex]1000W- 2W^2 = 0[/tex]

Rewrite as:

[tex]-2W^2 + 1000W = 0[/tex]

Assume the form of the above equation is: [tex]aW^2 + bW + c = 0[/tex]

The value of W that maximizes it is:

[tex]W = -\frac{b}{2a}[/tex]

Where

[tex]a = -2[/tex]

[tex]b = 1000[/tex]

[tex]c = 0[/tex]

So:

[tex]W = -\frac{1000}{2*-2}[/tex]

[tex]W = \frac{1000}{2*2}[/tex]

[tex]W = \frac{1000}{4}[/tex]

[tex]W = 250[/tex]

Recall that:

[tex]L = 1000 - 2W[/tex]

[tex]L =1000 - 2 * 250[/tex]

[tex]L =1000 - 500[/tex]

[tex]L = 500[/tex]

So, the dimensions that maximize the area is:

[tex]Length = 500ft[/tex]

[tex]Width = 250ft[/tex]

So, lets just go by segment to segment, using the process of elimination to see which graph is correct.

So the first segment of all the graphs is 18-19.9.

Lets look at the numbers given to us, and see how many times values between these two numbers occur. I see 19.9 and 18.6. This is two values.

This eliminates answer C, which has three values(a frequency of 3).

All the others have 2 values however, so lets keep going.

Next we have 20-21.9. I see 9 values that are in between 20-21.9:

20.7, 21.2, 20.5, 20.4, 21.6, 21.4, 21.5, 21.5, 21.9

Both B and D have graphs with 9 values that are between 2-21.9, however A only has 8 values.

Now lets look at 22-23.9. I see 8 values between 22-23.9:

22.2, 22.7, 22.1, 23.1, 23.8, 22.6, 23.9, 23.4

This eliminates D, which only has 7 values, but B does have 8 values.

So this means that B is the answer!

Step-by-step explanation:

If all 20 students joined the same event, the shape of the histogram will change as compared to the original. A.) The Chili Cook-off would be more skewed and D.) The Pie Eating Contest would be less symmetrical.

What is a skewed histogram?If most of the data are on the left side of the histogram but a few larger values are on the right, the data are said to be skewed to the right.If most of the data are on the right, with a few smaller values showing up on the left side of the histogram, the data are skewed to the left.

If 20 students get added to the 0-19 age group in Chili Cookoff contest, the frequencies of the number of students would be 50, 50, 40, 10. Since,  the frequencies are decreasing with increasing age group, the histogram is skewed.

What is symmetric histogram?

If the data are symmetric, histogram have about the same shape on either side of the middle. In other words, if you fold the histogram in half, it looks about the same on both sides.

If we add 20 to the 0-19 age group in Pie eating contest, the frequencies of the number of students would be 40, 40, 60, 50. Since the frequencies are monotonically increasing and then decreasing, the histogram is symmetrical but it doesn't look exactly same on either side.

C=50+20h

C=(50+20)h

C=h+50+20

C=20+50h

Answers

Answer:

C=50+20h

Step-by-step explanation:

Since 20 is going to be added every hour, that is the h value. Since 50 is the the initial payment, that is the other value

The equation for total fees charged, if One plumber charges a flat fee of $50, The per hour fees = $20, is C = 50 + 20h, so option A is correct.

Is it possible to find two data sets A and B such that A has a greater median and mode, while B has a greater average and range? If you think the answer is yes, provide an example. If you think the answer is no, explain why not.

Answers

Answer:

For a data set of N elements:

{x₁, x₂, ..., xₙ}

The median is the middle value (or the average of the two middle values)

The average or mean is:

[tex]m = \frac{x_1 + ... + x_n}{N}[/tex]

The mode is the value that is more repeated.

The range is the difference between the largest value and the smallest value.

Now, let's try to construct two sets A and B that meet the required conditions:

Let's suppose two sets of 5 values each:

A = {2, 2, 3, 4, 5}

The median of A is 3.

The range of A is = 5 - 2 = 3

The average of A is: (2 + 2 +3 +4 +5)/5 = 16/5

And the value "2" appears two times, so the mode is 2.

Now, let's try to find a data set B such that:

The mode is smaller than 2  (so for example, we can have a "1" that repeats two times)

The median is smaller than 3 (let's have a median equal to 2)

The average is larger than 16/5

The range is larger than 3

This is ratter simple:

B = {1, 1, 2, 6, 9}

The median of B is 2.

The mode of B is 1

The range of B is: 9 - 1 = 8

The average of B is: (1 + 1 + 2 + 6 + 9)/5 = 19/5

So, we just found an example for two data sets A and B such that A has a greater median and mode, while B has a greater average and range.

So the answer is yes, it is possible.

Answers

Answer:

The man has made a profit, for with the same money he bought more British Pounds than he could have bought a week later.

Step-by-step explanation:

Given that a man converted Rs. 150000 into pound sterling, and after one week Nepalese rupees devalued by 5%, to find if you have obtained a profit or a loss, the following calculation must be performed:

150,000 / 77.02 = X

1,947.55 = X

150,000 / (77.02 x 1.05) = X

150,000 / 80.87 = X

1,854.82 = X

Therefore, the man has made a profit, for with the same money he bought more British Pounds than he could have bought a week later.

Step-by-step explanation:

This problem meets requirement that enables us to use the binomial probability relation :

Probability of success, p = 17% = 0.17

number of trials = 9

(1 - p) = 1 - 0.17 = 0.83

The binomial probability relation :

P(x = x) = nCx * p^x * (1 - p)^(n-x)

P(x = 3) = 9C3 * 0.17^3 * 0.83^6

P(x = 3) = 84 * 0.001606258054361897

P(x = 3) = 0.134925676566399348

P(x = 3) = 0.13492

P(x = 4) = 9C4 * 0.17^4 * 0.83^5

P(x = 4) = 126 * 0.000328992613544003

P(x = 4) = 0.041453069306544378

P(x = 4) = 0.04145

P(x = 3 or x = 4) = P(x = 3) + p(x = 4)

= 0.13492 + 0.04145

= 0.17637

= 0.1764

A large tank is filled to capacity with 700 gallons of pure water. Brine containing 4 pounds of salt per gallon is pumped into the tank at a rate of 7 gal/min. The well-mixed solution is pumped out at a rate of 14 gallons/min. Find the number A(t) of pounds of salt in the tank at time t.

Answers

Answer:

[tex]A(t) = 1400(1 - e^{\frac{-t}{50}})[/tex]

Step-by-step explanation:

The net mass flow rate dA/dt = mass flow rate in - mass flow rate out

mass flow rate in = concentration of brine in × brine flow rate in = 4 lb/gal × 7 gal/min = 28 lb/min

Let A(t) be the amount of salt at time t. The concentration of salt in the tank at time, thus C = amount of salt/volume of tank = A(t)/700 lb/gal.

Since the well mixed solution is pumped out at a rate of 14 gal/min, the mass flow rate out = concentration of salt in tank × volume flow rate out = A(t)/700 lb/gal × 14 gal/min = m(t)/50 lb/min

So, dA/dt = mass flow rate in - mass flow rate out

dA/dt = 28 lb/min - A(t)/50 lb/min

dA/dt = 28 - A(t)/50

dA/dt = [1400 - A(t)]/50

separating the variables, we have

dA/[1400 - A(t)] = dt/50

integrating both sides, we have

∫dA/[1400 - A(t)] = ∫dt/50

-1/-1 × ∫dA/[1400 - A(t)] = ∫dt/50

1/-1 × ∫-dA/[1400 - A(t)] = ∫dt/50

-1 × ㏑[1400 - A(t)] = t/50 + C

-㏑[1400 - A(t)] = t/50 + C

㏑[1400 - A(t)] = -t/50 - C

taking exponents of both sides, we have

[tex]1400 - A(t) = e^{\frac{-t}{50} - C} \\1400 - A(t) = e^{\frac{-t}{50}}e^{-C}\\1400 - A(t) = Be^{\frac{-t}{50}} ( B = e^{-C}) \\A(t) = 1400 - Be^{\frac{-t}{50}}[/tex]

when t = 0, A(0) = 0. So,

[tex]A(t) = 1400 - Be^{\frac{-t}{50}}\\A(0) = 1400 - Be^{\frac{-0}{50}}\\0 = 1400 - Be^{0}\\0 = 1400 - B\\B = 1400[/tex]

So,

[tex]A(t) = 1400 - 1400e^{\frac{-t}{50}}\\A(t) = 1400(1 - e^{\frac{-t}{50}})[/tex]
