Answer 1

The sample standard deviation weight of the 50 candies is, 0.07 grams.

What is standard deviation ?

The amount of variation or dispersion in a set of data values is measured by standard deviation. A statistical calculation is used to determine how far the values vary from the mean (average) value. While a high standard deviation suggests that the data values are more dispersed, a low standard deviation suggests that the data values tend to be close to the mean.

To find the sample standard deviation weight,

we can use the formula:

[tex]s = \sqrt{((1/(n-1))} \sum((x - \bar x)^{2} ))[/tex]

where n is the sample size, x is the weight of each candy, [tex]\bar x[/tex] is the sample mean weight, and sum() means to add up the values.

We can first find the sample mean weight:

[tex]\bar x[/tex]= (0.98 + 0.85 + 0.92 + 0.98 + 0.71 + 0.88 + 0.86 + 0.75 + 0.85 + 0.85 + 0.86 + 0.78 + 0.75 + 0.75 + 0.74 + 0.82 + 0.85 + 0.91 + 0.78 + 0.72 + 0.81 + 0.81 + 0.81 + 0.84 + 0.87 + 0.85 + 0.89 + 0.77 + 0.85 + 0.97 + 0.74 + 0.89 + 0.82 + 0.86 + 0.82 + 0.84 + 0.91 + 0.87 + 0.94 + 0.85 + 0.71 + 0.83 + 0.87 + 0.94 + 0.81 + 0.81 + 0.78 + 0.77 + 0.85) / 50

[tex]\bar x[/tex] = 0.8456

Next, we can calculate the sample standard deviation:

s = √((1/(50-1)) x ((0.98-0.8456)² + (0.85-0.8456)² + ... + (0.77-0.8456)² + (0.85-0.8456)²))

s = sqrt(0.0045916)

s = 0.0678

Rounding to two decimal places, the sample standard deviation weight is 0.07 grams.

The compression ratio in a certain engine is 7.5 to 1. If the expanded volume of a cylinder is 15 cu​ in., what is the compressed​ volume?

Answers

On solving the provided question, we can say that  inches if a cylinder's enlarged capacity is 45 in3, its compressed volume is 6 in cubic .

what is cylinder?

One of the most fundamental curved geometric forms is the cylinder, which is often a three-dimensional solid. It is referred to as a prism with a circle as its base in elementary geometry. Several contemporary fields of geometry and topology also define a cylinder as an indefinitely curved surface. A three-dimensional object known as a "cylinder" consists of curving surfaces with circular tops and bottoms. A cylinder is a three-dimensional solid figure that has two bases that are both identical circles joined by a curving surface at the height of the cylinder, which is determined by the distance between the bases from the center. Examples of cylinders are cold beverage cans and toilet paper wicks.

In a certain engine, the compression ratio is 7.5: 1.

A cylinder's enlarged volume is 45 in3 in.

We must determine the cylinder's compressed volume.

Let v represent the cylinder's compressed volume.

The aforementioned circumstance can be described as

7.5 : 1 = expanded volume : compressed volume

7.5/1 = 45/v

7.5 = 45/v

v = 45/7.5

v = 6 cubic inches .

Therefore, if a cylinder's enlarged capacity is 45 in3, its compressed volume is 6 in cubic .

A quadratic function has a vertex at the point (-1, 3) and passes through the point (-4, -6).

Answers

The quadratic function is of the given question is f(x) = [tex]-2x^{2}[/tex] + 10x + 1.

What is quadratic equation?

When a, b, and c are constants and x is an unknown variable, the equation has the form [tex]ax^{2}[/tex] + bx + c = 0, which is known as a quadratic equation. The unknown variable x is solved for using the quadratic equation.

The largest power of the variable in a quadratic equation is two. The variable is now squared, but it may also have a coefficient, often known as a multiplier, in front of it. Two more components in the equation are made up of a constant and a variable with an exponent of 1.

In the given question,

The equation of the quadratic function with a vertex at (-1, 3) and passing through (-4, -6) can be written as:

y = [tex]a(x + 1)^{2}[/tex] + 3

Where a is a constant that determines the shape of the function. To find the value of a we can substitute the coordinates of the vertex and the point into the equation and solve for a.

Substituting (x, y) = (-1, 3) into the equation:

3 = [tex]a(-1 + 1)^{2}[/tex] + 3

Simplifying:

3 = [tex]a(0)^{2}[/tex] + 3

3 = 3

Since both sides are equal, a = 1.

Substituting (x, y) = (-4, -6) into the equation:

-6 = [tex]a(-4 + 1)^{2}[/tex] + 3

Simplifying:

-6 = [tex]a(-3)^{2}[/tex] + 3

-6 = 9a + 3

-9 = 9a

Divide each side by 9:

-1 = a

Since both values of a are equal, a = -1.

Therefore, the equation of the quadratic function with a vertex at (-1, 3) and passing through (-4, -6) is:

y = [tex]-(x + 1)^{2}[/tex] + 3

Answers

The total cost of the ingredient to make the cake and the comparison to the percentage discount to get the best deal indicates that we get;

The total cost of the ingredient for the cake is $37.78The best deal is to purchase the 4 items and minimize spending

What is a percentage?

A percentage is the representation of a proportion of an item per 100 of a set of items.

Quantity of flour = 5 lb

Unit cost for the flour = $2.74 per lb

Quantity of sugar = 2 1/2 lb

Unit cost of the sugar = $1.70 per lb

Quantity of butter = 2 lb

Unit cost of the butter = $7.49 per lb

Quantity of eggs required = 1/2 dozen

Cost of six eggs = $4.85

Miss Brown's total bill for the four items, C, is therefore;

C = 5 × 2.74 + (2 1/2) × 1.7 + 2 × 7.49 + 4.85 = 37.78

Her total cost for the four items, C = $37.78

The discount available for purchases of $50 or more = 5% discount on the purchase

The amount of more money she will have to spend to get the 5% discount is therefore;

$50 - $37.78 = $12.22

Miss Brown will have to spend $12.22 extra to get the 5% discount

The 5% discount indicates that spending $50, Miss Brown only has to pay $50 - $50 × 5% = $47.5

Therefore, in order to get the discount, the total amount spent on the purchase is increase by $47.5 - $37.78 = $9.72, and the amount saved from the discount is $2.5, therefore;

Miss Brown should purchase the four items

The probability that the sum of the ticket is 5, expressed as a percentage is 30%

What is the probability that an event will occur?

The probability that an event will occur can be found by the ratio of the number of times the event occurs to the number of all possible events.

The five tickets in the box = 1, 2, 3, 4, 3

The tickets that sum to 5 are; 1 and 4, 2 and 3

The probability that the first ticket picked is 1 = 1/5

The probability that the next ticket picked is a 4 = 1/(5-1) = 1/4

Therefore, the probability of picking a 1 and 4 = (1/5) × (1/4) = 1/20

Similarly, the probability of picking a 4 and then a 1 is 1/20

The probability of picking tickets with numbers 1 and 4 in either order therefore = 2 × 1/20 = 1/10

The probability that the first ticket drawn is 2 = 1/5

The probability that the next ticket picked is a 3 = 2/(5-1) = 1/2

Therefore, the probability to draw a 2 and 3 = (1/5) × (1/2) = 1/10

The probability that the first ticket picked is 3 = 2/5

The probability that the next ticket picked is a 2 = 1/(5-1) = 1/4

Therefore, the probability of picking a 3 and 2 = (2/5) × (1/4) = 2/20 = 1/10

The probability of picking a 2 and a 3 in either order is therefore;

1/10 + 1/10 = 2/10 = 1/5

The probability that the sum of the ticket is 5, is the sum of the probabilities of picking a 1 and a 4 and the probability of picking a 2 and a 3, which is; 1/10 + 1/5 = 3/10 = 0.3

The probability that the sum of the ticket is 5, therefore is 0.3 × 100 % = 30%

solve. a certain phone call costs 75 cents for the first 3 minutes plus 15 cents for each additional minute. if the call lated x minutes and x is an integer greater than 3, what is cost in dollars

Answers

(1) The cost of the phone call was less than $4.16

(2) The cost of the phone call was greater than $3.35

While this is a seemingly simple min/max problem, I was wondering if there is a faster way to deal with decimals—as it took me ~4mins to arrive at the solution.

The cost of a certain phone call was $0.75 for the first 3 minutes and $0.20 for each additional minute after the first 3 minutes. Did the phone call last longer than 15 minutes

According to the above the cost for n minutes, where n>3, is 75 + (n−3)∗20=20n+15

cents. W need to find whether n>15. The cost for 15 minutes is 20n+15=20∗15+15=315

, so we need to find whether the cost is greater than 315 cents.

(1) The cost of the phone call was less than $4.16. Not sufficient.

(2) The cost of the phone call was greater than $3.35. Sufficient.

Find the surface area (in square feet) of a right circular cylinder of height 4 feet whose base has radius 3 feet. Round the answer to the nearest tenth of a square foot.

Answers

Answer:

After rounding the nearest tenth of a square foot, the surface area of the  circular cylinder is 131.88 feet^2.

Step-by-step explanation:

To find surface area of a right circular cylinder we can use the formula,

A = 2πrh + 2πr^2

Here A is surface area,

π is mathematical constant ,

r is radius, and h is the height of the cylinder.

We have

r = 3 ft

h = 4 ft,

Now we put the values to find the surface area,

A = 2π × 3 × 4 + 2π ×3^2

A = 24π + 18π

A = 42π

A= 42×3.14                             (we know π = 3.14 )

A = 131.88

After rounding the nearest tenth of a square foot, the surface area of the  circular cylinder is 131.88 feet^2.

Graph the system of equations. Then determine whether the system has no solution, one solution, or infinitely many solutions. If the system has one solution, name it.
y=x-2
y=x-1

Answers

The system of equations are parallel lines and they do not intersect. Thus, the system has no solution.

What are parallel lines?

Parallel lines are any two or more lines that all lie in the same plane and never cross one another. They are equally spaced apart and have the same incline.

No matter how far we extend a parallel line, it will never meet another parallel line.

Given that,

y=x-2

y=x-1

For x = 1:

y = x - 2 = 1 -2 = -1

y = x - 1 = 1 - 1 = 0

For x = 2:

y = 2- 2 = 0

y = 2 -1 = 1

Plot the graph using the points.

The two lines have the same slope hence they are parallel lines.

Since, the two lines are parallel the system has no solutions.

=break your pencil lead while writing, and = feel overly stressed.

=put together a swing set correctly, and =read the directions.

These are independent events because the occurrence of one event does not affect the occurrence of the other event. Breaking a pencil lead while writing and feeling overly stressed may happen at the same time, but one event does not cause the other. Similarly, putting together a swing set correctly and reading the directions are independent events because one action (reading the directions) does not determine the outcome of the other action (assembling the swing set correctly).

=make an error on your income tax return, and =file Form 1040 long.

These are dependent events because the occurrence of one event (making an error on the tax return) affects the occurrence of the other event (filing Form 1040 long). If you make an error on your tax return, you may need to file a longer form to correct it.

=have a salad with dinner, and =work on a home project.

These are also dependent events because one event (having a salad with dinner) does not determine the outcome of the other event (working on a home project). These events may happen at the same time, but one does not cause the other.

Answers

The median of the following salary list is 29763.

What is a median?

The median is the average in the centre of a data collection, which means that 50% of the data points have a value less than or equal to the median, and 50% of the data points have a value greater than or equal to the median. For a small data collection, calculate the number of data points (n) and organize them in ascending order.

The middle score in the group is called the median. Begin by sorting all of the data sets from lowest to highest before calculating the median. The median in an odd-numbered set will be the value that falls exactly in the center of the list. You must determine the average of the two middle integers in a set of even numbers.

Arrange in ascending order

What is the difference in the outputs that you get when you use the following operators =; == ; and ===. Explain how the steps Ansel Adams took for each photograph reflected his philosophy "that there are no shortcuts to excellence." Use evidence from "excerpt 1 from Ansel Adams: Americas Photographer" to support your answer. Story: By 1839, three EuropeansLouis Daguerre, Joseph-Nicphore Niepce, and William Henry Fox Talbothad independently developed a way to make images that would not disappear. With their inventions, photography became a reality. At first, photography was immensely popular for taking family portraits. Then it was used to imitate painting until it gradually became accepted as an art form on its own almost one hundred years later. When Ansel Adams began taking photographs of Yosemite in 1916, he was young and so was photography. His first camera was a Kodak Box Brownie. Through the years he tried dozens of different cameras, from a heavy 8 x 10-inch wooden camera that used glass plates to a small 35mm camera, and even a Polaroid camera that gave him immediate results. Before he took a photograph, he visualized the scene as he expected it to look. Then he put his camera away, got out his battered notebook, [and found] a convenient rock, stump, or fender to lean upon. On his exposure chart, he recorded film speed, lens, filter, shutter speed, zone number, and any suggestions for developing the print in the darkroom. In addition to his ability to visualize a scene, his ability in the darkroom helped him become a master photographer. Over the years he experimented with paper, chemicals, and other materials used in order to make the finest prints possible. I know from experience that there are no shortcuts to excellence, he said. Although Ansel is famous for his black-and-white photographs, people often wonder whether he did work with color photography. He worked in color starting in the mid-1940s and eventually made more than three thousand color transparencies, mainly on assignment for commercial projects. However, he did not develop the transparencies himself and felt that he could not control color in the same way he could his black-and-white work. Because color prints, transparencies, and negatives were subject to extensive fading over time, Ansel and most of his peers did not feel that color was a reliable form of art photography. Ansel admitted that if he had been a young man when computers first enabled artists to manipulate color photography, he certainly would have explored its possibilities more fully. there 10 cars in a race. in how many ways can three cars finish the race as the 1st, 2nd, and the 3rd places?
