Answer: 399

Step-by-step explanation:

Given: A store sold 1,330 mattresses within a single year.

With 30% of the mattresses being king size, we calculate the number of king size mattresses as follows:

30% of 1330

Use '×' instead of 'of' and convert the percentage to decimal by dividing by 100, resulting in:

\dfrac{30}{100}\times1330=\dfrac{39900}{100}=399

Thus, the total of king size mattresses sold = 399

The yearly sales total for mattresses equals 1,330.

The percentage of King size mattresses sold is 30% = 30/100 = 0.3

Now, we need to find the actual sales number using the following formula:

King size mattresses sold = Total mattresses sold in a year * Percentage of King size mattresses sold

King size mattresses sold = 1,330 * 0.3 = 399

King size mattresses sold = 399

Inessa [3907]

Answer:

Step-by-step explanation:

A survey of 8225 Americans included age data collection.

The mean age was recorded as 42, whereas the median was noted as 37.

This indicates median < mean.

When the mean exceeds the median, it suggests the presence of right skewness in the data.

In a symmetrical distribution, mean and median align. If there is a discrepancy, the distribution is skewed.

Consequently, with the mean > median, the data is skewed to the right.

Write 337,060 in expanded from using exponents
Leona [4166]

Answer:

We start with the number 337 060.

Expanded form refers to a way of representing a standard form number in more detail.

This number will be converted to expanded form utilizing exponents.

=> 337 060

To begin, let's break down each component.

=> 300 000 = 3 x 10^5

=> 30 000 = 3 x 10^4

=> 7 000 = 7 x 10^3

=> 60 = 6 x 10^1

=> 3 x 10^5 + 3 x 10^4 + 7 x 10^3 + 6 x 10^1 – this is the expanded form of the number using exponents.

What does distributions from owners int non adr mean?
AnnZ [3877]
Distributions from owners refer to payments that business owners take out from profits the firm earns, commonly issued as dividends. An ADR, or American Depositary Receipt, is a type of stock bought and sold within the U.S. market that represents a specific number of shares in a foreign company. Therefore, the owner’s payments do not originate from the ADR shares.

Solve 12-5x-4kx=y for x
lawyer [4008]

Response:

x = -y-12/5 + 4k

Detailed explanation:

Solve for x in the equation 12 - 5x - 4kx = y

12 - 5x - 4kx = y

Subtract 12 from both sides

-5x - 4kx = y - 12

Factor out -5x - 4kx to get -x(5 + 4k)

-x(5 + 4k) = y - 12

Now isolate x

-x = (y - 12)/(5 + 4k)

Thus, x = -y - 12/5 + 4k
