The height of the cylindrical tub of ice cream is 6.75 inches.

A cylinder is a 3 dimensional shape which has a curved side and two circular surfaces. The total surface area can be determined by the expression;

total surface area of a cylinder = 2πr^2 + 2πrh

where r is the radius of it circular surface, and h is its height.

Considering the given question, we have;

total surface area of a cylinder = 2πr^2 + 2πrh

But total surface area = 183.69 square inches

r = D/2

  = 6/ 2

r = 3 inches

Thus,

183.69 = 2*3.14*3^2 + 2*3.14*3*h

           = 56.52 + 18.84h

183.69 - 56.52 = 18.84h

127.17 = 18.84h

h = 127.17/ 18.84

  = 6.75

The height of the cylindrical tub of ice cream is 6.75 inches.

Answer: The answer is (C) 6.75

Step-by-step explanation:

The formula for Surface Area is: SA = 2πr^2 + 2πrh

Let's do the first part: 2πr^2

So you need to find the radius, which is half the diameter. 6 is the diameter so half that, and you get 3.

Now, times 3 by itself

3 * 3 = 9

And then times 9 by 2

9 * 2 = 18

And times 18 by pi, 3.14

18 * 3.14 = 56.52

Now that we have our first value, lets move on to the second part of the formula: 2πrh

So we need the diameter, and the question gives us the value of the diameter.

6 is the diameter

so times 6 by pi, 3.14

6 * 3.14 = 18.84h  (leave h there because we don't know the height)

Now do this:

183.69 =  56.52 + 18.84h

You cannot add 56.52 and 18.84h because they are not like terms

So take away 56.52 from both sides

56.52 - 56.52 = 0

183.69 - 56.52 = 127.17

Now divide 127.17 by 18.84h

127.17/18.84  = 6.75 inches

Here is proof that my answer is correct. I have a photo of my results and it shows that 6.75 inches is correct. Here is the photo:

The value of x and y in the right triangle are as follows:

x = 15√3 units

y = 30 units

A right triangle is a triangle that has one of its angles as 90 degrees. The sum of angles of a right angle triangle is 180 degrees.

The side x and y can be found using trigonometric ratios,

tan 60° = opposite / adjacent

tan 60° = x / 15

cross multiply

x = 15 tan 60°

x = 15 × √3

x = 15√3 units

Let's find y as follows:

cos 60° = adjacent / hypotenuse

cos 60° = 15 / y

cross multiply

y = 15 / cos 60

y = 15 ÷ 1 / 2

y = 15(2)

y = 30 units

Answer:

Step-by-step explanation:

Let x be the number of $1.78 paperback books and y be the number of $2.51 hardcover books that were sold. The total number of books is x + y = 30 and the total amount of money earned is $62.16. The cost of the paperback books is x * $1.78 and the cost of the hardcover books is y * $2.51.

So, we have the following system of equations:

x + y = 30 (the total number of books is 30)

x * $1.78 + y * $2.51 = $62.16 (the total amount of money earned is $62.16)

This system of equations can be used to determine the number of $1.78 paperback books and the number of $2.51 hardcover books that were sold at the yard sale.

Bob continues his research because even though there is no linear equation relationship between the number of bedrooms and selling price, there could be another type of relationship.

Bob continues his research because even though the correlation value he calculated between the number of bedrooms and the selling price was only 0.05, this does not necessarily mean that there is no relationship of any kind between these two variables. It simply means that there is no linear relationship between the two. There could still be other types of relationships between the two variables, such as an exponential or quadratic relationship. It is possible that further analysis and exploration of the data set would reveal such a relationship and allow Bob to uncover the relationship between the two variables. Additionally, even if the correlation value is low, it does not necessarily mean that there is no relationship between the two variables. It simply means that the relationship is weak.

where x is the required length of the paper in pages.

First, we can simplify the right-hand side of the equation:

80% / 100% = 0.8

Next, we can solve for x by cross-multiplying:

48 pages / 0.8 = x

x = 60 pages

The manager would expect 1000 defective players in the shipment.

A store receives a shipment of 5,000 mp3 players out of which 300 were found to be defective.

The clerk lets the numbers 1 through 300 represent defective mp3 players, and the numbers 301 through 5,000 represent working mp3 players.

The results are given AS:

2,806 623 232 3,955 3,799 657 2,140 262 844 561

This means that out of the 10 samples 2 were found to be defective and 8 were in the working condition.

( Since the number 232 and 262 represent the defective mp3 players as they are the numbers which are less than or equal to 300 )

Hence, the Probability that the mp3 players were defective is:

P( defective)=2/10=1/5

The median of the given standard data set 9, 3, 10, 12, 4, 5, 12, 2 will be calculated approximately to 7. So , the median of the dataset is 7.

The median is a measure of central tendency that gives us an idea of where the "middle" of a data set lies. In other words, it gives us a value that separates the data set into two equal parts, with half of the values being above the median and the other half being below the median.

To find the median of a data set, the first step is to arrange the values in ascending or descending order. This makes it easier to identify the middle value(s) in the data set.

If the data set has an odd number of values, then there is a single middle value and that value is the median. For example, if we have the data set: 1, 2, 3, 4, 5, the median would be 3 because it is the middle value in the ordered set.

If the data set has an even number of values, then there are two middle values and the median is the average of those two values. For example, if we have the data set: 1, 2, 3, 4, 5, 6, the median would be the average of 3 and 4, which is (3 + 4) / 2 = 3.5.

So, in the case of the data set: 9, 3, 10, 12, 4, 5, 12, 2, we arrange the values in ascending order: 2, 3, 4, 5, 9, 10, 12, 12. Since there are 8 values, which is an even number, there are two middle values: 5 and 9. The median is the average of these two values, which is (5 + 9) / 2 = 7.

The account with compound interest of 7.2 % quarterly after 5 years is given by A = $ 1,428.75

Compound interest is interest based on the initial principle plus all prior periods' accumulated interest. The power of compound interest is the ability to generate "interest on interest." Interest can be added at any time, from continuously to daily to annually.

The formula for calculating Compound Interest is

A = P ( 1 + r/n )ⁿᵇ

where A = Final Amount

P = Principal

r = rate of interest

n = number of times interest is applied

b = number of time periods elapsed

Given data ,

Let the amount after compound interest be represented as A

Now , the equation will be

The initial principal amount = $ 1000

The rate of interest r = 7.2 %

The number of times interest is applied n = 4 ( quarterly )

The number of years b = 5 years

A = P ( 1 + r/n )ⁿᵇ

Substituting the values in the equation , we get

A = 1000 ( 1 + 0.072/4 )⁴ˣ⁵

On simplifying the equation , we get

A = 1000 ( 1 + 0.018 )²⁰

On further simplification , we get

A = 1000 ( 1.018 )²⁰

A = $ 1,428.75

Hence , the amount after 5 years is $ 1,428.75
