The numbers of rooms for 15 homes recently sold were: 8, 8, 8, 5, 9, 8, 7, 6, 6, 7, 7, 7, 7, 9, 9. what is the sample standard deviation?

Answers

Answer 1
From the data set given:
8, 8, 8, 5, 9, 8, 7, 6, 6, 7, 7, 7, 7, 9, 9
to get the standard deviation we use the formula for variance given by:
σ²=[Σ(x-μ)²]/(n-1)
σ² is the variance
μ is the mean
The mean of the data will be:
μ=(8+8+8+5+9+8+7+6+6+7+7+7+7+9+9)/15=7.4
The variance will be found as follows:
σ²=[(8-7.4)²×4+(5-7.4)²+3×(9-7.4)²+5×(7-7.4)²+2×(6-7.4)²]/(15-1)
σ²=1.4
thus
σ=√1.4=1.1183





Answer 2
Answer:

Hence, the sample standard deviation is:

                         1.1832

Step-by-step explanation:

The data is given by:

8, 8, 8, 5, 9, 8, 7, 6, 6, 7, 7, 7, 7, 9, 9.

The mean of these data points is given by:

[tex]Mean(x')=\dfrac{8+8+8+5+9+8+7+6+6+7+7+7+7+9+9}{15}\\\\i.e.\\\\Mean(x')=\dfrac{111}{15}\\\\i.e.\\\\Mean(x')=7.4[/tex]

Now,

x                x-x'                   (x-x')²

8            8-7.4=0.6              0.36

8            8-7.4=0.6              0.36

8            8-7.4=0.6              0.36    

5            5-7.4= -2.4             5.76

9            9-7.4=1.6                2.56

8            8-7.4=0.6              0.36

7            7-7.4= -0.4             0.16

6            6-7.4= -1.4              1.96

6            6-7.4= -1.4              1.96

7            7-7.4= -0.4             0.16

7            7-7.4= -0.4             0.16

7            7-7.4= -0.4             0.16

7            7-7.4= -0.4             0.16

9            9-7.4=1.6                2.56

9            9-7.4=1.6                2.56

                             ∑(x-x')²=19.69          

Now the variance of the sample population is given by:

[tex]Variance=\dfrac{\sum (x-x')^2}{n-1}[/tex]

where  n is the number of data points.

Here n= 15

Hence, n-1=14

Hence, we get:

[tex]Variance=\dfrac{19.6}{14}\\\\i.e.\\\\Variance=1.4[/tex]

We know that the standard deviation is the square root of the variance.

i.e.

[tex]Standard\ deviation=\sqrt{1.4}\\\\i.e.\\\\Standard\ deviation=1.1832[/tex]

Iris is building a model of the Washington Monument. Her model measures 15 in. tall and is 1.5 in. wide at the base. The actual width measurement at the base of the Washington Monument is about 55 ft. About how tall is the Washington Monument?

Answers

Using how tall it is over how wide
=>tall/wide
The model 15in/1.5in
The actual x/55ft

Convert everything into the same units so 55ft to inches
There are 12in in 1ft
55ft * 12in/1ft
The ft cross out leaving in
55*12in= 660 in

So
15in/1.5in = x/660in
Now solve for x my multiplying both side by 660in
660in *15in/1.5in=x
x= 6600in tall




Answer: 550

Step-by-step explanation:Solve the proportion:  15 in./1.5 in. =  h/55 ft. The value of h is 550 ft. The Washington Monument is about 550 ft tall.

Find the area of the figure

Answers

You can solve each figure individually; the parallelogram, and the trapezoid.

The parallelogram, you can just do base * height. The base is 11 yards, and the height is 4 yards. 11 * 4 = 44 square yards.

Now for the trapezoid. If you split it up into a rectangle and a triangle, it becomes much more easier to solve. The rectangle and triangles can be made by splitting the figure down the center. This makes a rectangle with a length of 7 yards and a height of 8, and a triangle with a base of 7 yards and a height of 8 as well.

Solve for the area of both shapes.

The rectangle: Multiply length * height: 7 * 8 = 56 square yards

The triangle: Multiply base * height, and then divide by 2: 7 * 8 = 56
56 / 2 = 28 square yards

Now add the areas together.

28 + 56 + 44 = 128 square yards

Hope this helped!
These are the steps:
1. Find area of the trapezium.
2. Find area of the parallelogram.
3. Add the 2 areas together.


Step 1: Find the area of the trapezium:

Formula : area = 1/2 (a + b) h

Area = 1/2(7 + 14) (8) = 84 yd²


Step 2: Find the area of the parallelogram:

Formula : area = base x height

Area = 11 x 4 = 44 yd²


Step 3: Find the total area:

Total Area = 84 + 44 = 128 yd²

Answer: 128 yd²

You have been averaging 55 sales per day. Per our new policy, everyone needs to increase his or her sales per day by 10% in the next month. Rounding up, by next month you will need to be up to __________ sales.

Answers

The next month sales should be 1,815.

Given that,

You have been averaging 55 sales per day. increase his or her sales per day by 10% in the next month

Based on the above information, the calculation is as follows:

[tex]= 55 \times 1.10 \times 30 days[/tex]

= 1,815

Learn more: https://brainly.com/question/25914450?referrer=searchResults

Final answer:

To meet the new policy of a 10% increase in sales, you would multiply your current average sales by the increase percentage and round up to the nearest whole number. Starting from 55 sales, a 10% increase results in an additional 5.5 sales, which when rounded up equals 6. Therefore, you need to achieve 61 sales per day.

Explanation:

If you have been averaging 55 sales per day and need to increase your sales by 10%, you will first need to calculate the increase. To calculate a 10% increase, you multiply your current average sales (55) by the percentage increase (10%), expressed as a decimal (0.10). The increase in sales can be found by the formula:

Increase = Current Sales × Percentage Increase

For your sales:

Increase = 55 × 0.10 = 5.5 sales

Since you need to round up, the increase will be 6 sales when considering whole units, as you cannot sell half a unit.

Therefore, the new target sales per day will be:

New Sales Target = Current Sales + Increase

New Sales Target = 55 + 6 = 61 sales

By next month, you will need to be up to 61 sales per day after rounding up.

Find the derivative of f(x) = (1 + 5x2)(x − x2) in two ways. use the product rule. f '(x) = perform the multiplication first. f '(x) = do your answers agree? yes no

Answers

Answer:

The answers agree.

[tex]f^{\prime}(x) = - 20x^{3} + 15x^{2} - 2x + 1[/tex]

Step-by-step explanation:

The product rule is:

[tex]f(x) = g(x)h(x)[/tex]

[tex]f^{\prime}(x) = g^{\prime}(x)h(x) + g(x)h^{\prime}(x)[/tex]

In this problem, we have that:

[tex]f(x) = (1 + 5x^{2})(x - x^{2})[/tex]

So

[tex]g(x) = 1 + 5x^{2}[/tex]

[tex]g^{\prime}(x) = 10x[/tex]

[tex]h(x) = x - x^{2}[/tex]

[tex]h^{\prime}(x) = 1 - 2x[/tex].

[tex]f^{\prime}(x) = g^{\prime}(x)h(x) + g(x)h^{\prime}(x)[/tex]

[tex]f^{\prime}(x) = (10x)*(x - x^{2}) + (1 + 5x^{2})(1-2x)[/tex]

[tex]f^{\prime}(x) = 10x^{2} - 10x^{3} + 1 - 2x + 5x^{2} - 10x^{3}[/tex]

[tex]f^{\prime}(x) = - 20x^{3} + 15x^{2} - 2x + 1[/tex]

Multiplication first:

[tex]f(x) = (1 + 5x^{2})(x - x^{2})[/tex]

[tex]f(x) = x - x^{2} + 5x^{3} - 5x^{4}[/tex]

[tex]f(x) = -5x^{4} + 5x^{3} - x^{2} + x[/tex]

[tex]f^{\prime}(x) = -20x^{3} + 15x^{2} - 2x + 1[/tex]

Comparing the results, we can see that the derivatives obtained using the two methods are indeed the same. The answer is yes.

What's the function about?

The derivative of f(x) = (1 + 5x2)(x − x2) can be found using the product rule and by performing the multiplication first.

Using the product rule:

The product rule states that the derivative of f(x)g(x) is f′(x)g(x)+f(x)g′(x).

In this case, f(x) = 1 + 5x2 and g(x) = x − x2. So the derivative of f(x)g(x) is:

f′(x)g(x)+f(x)g′(x)

=(10x+10x3)(x−x2)+(1+5x2)(2x−2x3)

=10x2−10x3+10x3−10x4+2x−2x3+1+10x2−10x3

=−10x4+12x2+2x

Performing the multiplication first:

We can first multiply out the expression (1 + 5x2)(x − x2) to get:

x2−5x4+x3−5x3+x−x2

=−5x4+12x2+x

Then, we can take the derivative of this expression to get the same derivative as we found using the product rule:

f′(x)=−10x4+12x2+2x

Therefore, the derivative of f(x) = (1 + 5x2)(x − x2) is -10x4+12x2+2x, regardless of whether we use the product rule or perform the multiplication first.

a = dv/dt, therefore, to get an expression for v(t), we would integrate the expression for a:
a = -20/(1+2t)^2
v = (1/2)*20/(1+2t) + k = 10/(1+2t) + k

The height of an object from a distance

Answers

y = height
x = distance from tower

tan(19.9) = y/x

tan(21.8) = y/(x-50)   ( x is 50 feet closer so subtract 50 from x)

find the tan of the angles:
tan19.9 = 0.362
tan21.8 = 0.400

replace those values in the equations:
0.362 = y /x
0.400 = y / (x-50)

rewrite to solve for height:
0.362x = y
0.400(x-50) = y  distribute the 0.400 and rewrite as 0.400x-20 =y

now solve:

0.362x = 0.400x-20

add 20 to each side:
0.362x +20 = 0.400x

subtract 0.362x from each side:

20 = 0.038x

divide both sides by 0.038
x = 20 / 0.038 = 526.3 feet

now that x is known replace x in the original equation and solve for y:

tan19.9 = y /x

0.362 = y / 526.3
y = 0.362 x 526.3
y = 190.5

the height of the tower is 190.5 feet

A rectangular storage area is to be constructed along the side of a tall building. a security fence is required along the remaining 3 sides of the area. what is the maximum area that can be enclosed with 800 m of fencing? (a = lw)

Answers

Let l represent the length of fence parallel to the side of the building. Then the width will be that of half the remaining fence, (800 -l)/2. The total area will be
  A = lw = l(800 -l)/2

This is the equation of a downward-opening parabola with zeros at l=0 and l=800. The zeros are symmetrical about the axis of symmetry of the parabola, which axis goes through the vertex. That is, the vertex is located at
  l = (0 +800)/2 = 400

The maximum aea that can be enclosed is 400 m long by 200 m wide, so is
  (400 m)×(200 m) = 80,000 m²
Final answer:

To find the maximum area enclosed with 800 m of fencing, the dimensions of the rectangular storage area need to be determined. The perimeter equation is derived to eliminate a variable, allowing the area to be expressed in terms of the remaining variable. Using this approach, the dimensions that maximize the area can be found.

Explanation:

To find the maximum area that can be enclosed with 800 m of fencing, we need to determine the dimensions that will result in the largest possible area. Let's assume the length of the rectangular storage area is L and the width is W.

Since there are 3 sides already covered by the security fence, the perimeter of the rectangular storage area will be: 2L + W = 800 m.

To find the maximum area, we need to eliminate one variable from the equation above. We can do this by expressing W in terms of L and substituting it back into the area formula A = LW.

By applying this approach, we can find the dimensions of the rectangular storage area that will enclose the maximum area with 800 m of fencing.

so finally the correct answer would be the first option 
150*pi in3

The required exact volume of the half cylinder is 150 π in³. Option A is correct.

To calculate the volume of a half cylinder, we need to find the volume of a full cylinder and then divide it by 2.

The formula for the volume of a cylinder is given by:

Volume = π * r² * h

where π is a constant approximately equal to 3.14159, r is the radius of the cylinder, and h is the height or length of the cylinder.

Given that the diameter of the cylinder is 10 inches, we can find the radius by dividing the diameter by 2:

Radius (r) = 10 in / 2 = 5 in

The height or length of the cylinder is given as 12 inches.

Now we can calculate the volume of the full cylinder:

Volume = π * (5 in)² * 12 in = 300 π in^3

Finally, to find the volume of the half cylinder, we divide the volume of the full cylinder by 2:

Volume of Half Cylinder = (300 π in³) / 2 = 150 π in³

Therefore, the exact volume of the half cylinder is 150 π in³.

You can solve for x by subtracting 11 from 15 to get 4. Once you've got 4, you can power 4 by 2 (4²) to get 16 as your answer

x=16

So the value of x is 16

Remark
I take it you want to find x.

Square both sides.
(sqrt(x + 11))^2 = (15)^2
 x + 11 = 225  Subtract 11 from both sides.
x = 225 - 11
x = 214

This graph shows how much Marie earns babysitting compared with the number of hours she works select the correct statement about the graph

Answers

The answer is D 

The graph reflects that she is getting paid 10 dollars an hour

If you plot the points, you will see she makes 5 dollars every half hour

Answer:

Option D is the answer.

Step-by-step explanation:

This graph represents a linear function representing earnings of Marie at y axis and hours of working at x axis. To get the change in Marie's earnings for every 5 hours we will find the slope of the given line.

Slope of the line will define the rate of change in earning of Marie with respect to the time.

End points of the line at time t = 0 and t = 5 hours are (0, 0) and (5, 50).

Therefore slope = [tex]\frac{y-y'}{x-x'}=\frac{50-0}{5-0}=\frac{50}{5}=10[/tex]

So for each hour she works her earnings go up by $10.

Option D is the correct option.

average of 1.99 3.29 2.45

Answers


[tex]1.99 + 3.29 + 2.45 = 7.73 \\ 7.73 \div 3 = 2.58[/tex]
The answer is 2.5766. Because if you add up all the numbers than you would get 7.73, and if you divide 7.73 by the amount of numbers there are, which is three, than you would get 2.5766.
