Answer:

The percent of increase from 6 to 9 is 50%

Step-by-step explanation:

Percentages

To calculate the percentage increase:

Work out the difference (increase) between the two numbers you are comparing.

Increase = New Number - Original Number.

Divide the increase by the original number and multiply the answer by 100.

We are required to find the percent increase from 6 to 9. Here: New number=9, Original number = 6

Increase = 9 - 6 = 3

Divide 3 by 6 and multiply the answer by 100:

3 / 6 * 100 = 50%

The percent of increase from 6 to 9 is 50%

Mr. aba builds a circular patio with a diameter of 12 feet he covers the patio with paving stones the cost of the paving stones

Sedaia [141]

1.) Find the area of the circle:
• Formula: A=pi•r^2

- To find the area of a circle, we need to have the radius, and since the diameter is 2x the length of the radius, the radius is 1/2 of the diameter.

Finding the radius: r=d/2

r=12/2

r = 6.

- Now that we know that r=6, we can substitute it into the formula:
• A=pi•r^2

A=pi•(6)^2

A=113.097

- The area of the circle is 113.097ft.^2. We know that a square foot is $10.50. So, we have 113.097 square feet at $10.50/sq. foot. This means that we will add $10.50 113.097 times. Therefore:

113.097 • 10.50 = 1,187.518

So, total, it will cost $1,187.518

At the ritz concert tickets for adults cost $6 and tickets for students cost $4. How many of each ticket were purchased if 480 t

Anni [7]

Answer: the number of adult tickets is 210

The number if student tickets is 270

Step-by-step explanation:

Let x represent the number of adult tickets that were purchased.

Let y represent the number of student tickets that were purchased.

At the ritz, concert tickets for adults cost $6 and tickets for students cost $4. If the cost of total tickets purchased is $2340, then,

6x + 4y = 2340 - - - - - - - -1

Total number of tickets purchased is 480. This means that

x + y = 480

x = 480 - y

Substituting x = 480 - y into equation 1, it becomes

6(480 - y) + 4y = 2340

2880 - 6y + 4y = 2340

- 6y + 4y = 2340 - 2880

-2y = - 540

y = - 540/-2 = 270

x = 480 - 270

x = 210

Find a set of 5 positive integers that has a possible mode of 5, a median of 7 and a mean of 9

Pavel [41]

Answer:

You could have a set of [5, 7, 13, 15, 5]

Step-by-step explanation:

The mode is 5 (5 occurs the most in the set).

Definition of the mode of a set:

The mode of a set of data is the value in the set that occurs most often. In the problem above, 18 is the mode. It is easy to remember the definition of a mode since it has the word most in it. Fun fact: The words mode and most both start with the letters mo.

The median is 7 (if you put the numbers in strictly increasing order, 7 will be the middle number).

Definition of the median of a set:

The median of a set of data is the middlemost number or center value in the set. The median is also the number that is halfway into the set. To find the median, the data should be arranged, first, in order of least to greatest or greatest to the least value.

The mean is 9 (5 + 7 + 13 + 15 + 5).

Definition of the mean of a set:

The mean is the mathematical average of a set of two or more numbers. The arithmetic mean and the geometric mean are two types of mean that can be calculated. Summing the numbers in a set and dividing by the total number gives you the arithmetic mean.

Hope this helps.

The number of hours a battery lasts before failing varies from battery to battery. The distribution of Failure times Fallows an

Margarita [4]

Answer:

C) the average failure time of a large number of batteries has a distribution that is close to Normal.

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$ .

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

In this question:

Distribution is skewed to the right.

However, for large samples of batteries, the sampling distribution of sample means will be approximately normal, which means that the answer is given by option c.
