Mrrafil [7]

Answer:

There is a very strong positive correlation between size of a cell phone data plan and the number of text  messages sent in the U.S.

Step-by-step explanation:

The correlation coefficient is a statistical degree that computes the strength of the linear relationship amid the relative movements of the two variables (i.e. dependent and independent).It ranges from -1 to +1.

Positive correlation is an association amid two variables in which both variables change in the same direction.  A positive correlation occurs when one variable declines as the other variable declines, or one variable escalates while the other escalates.

Negative correlation is a relationship amid two variables in which one variable rises as the other falls, and vice versa.

The correlation coefficient for the relationship  between the size of a cell phone data plan, x, and the number of text  messages sent, y is:

<em>r</em> = +0.97.

The correlation value is very close to +1.

So, we can say that there is a very strong positive correlation between size of a cell phone data plan and the number of text  messages sent in the U.S.

Andrea, Dina, and Lindsay invested in a partnership in the ratio of 7:9:14, respectively.
Scrat [10]

The new ratio of ownership once the business was owned by only Andrea and Lindsay is 8 : 7

<h3>a. How much did Andrea pay Dina for her share of the partnership? </h3>

The ratio is given as:

Andrea : Dina : Lindsay = 7 : 9 : 14

The partnership worth is given as

Worth = $1,800,000

The amount received by Dina is:

Dina = Dina Ratio/Total Ratio * Worth

So, we have

Dina = 9/(7 + 9 + 14) * 1800000

Evaluate

Dina = 540000

Hence, Andrea pays Dina $540,000 for her share of the partnership

<h3>What percent of the business did Andrea own after she bought out Dina? </h3>

Initially, we have:

Andrea : Dina : Lindsay = 7 : 9 : 14

So, the new ratio is

Andrea : Lindsay = (7 + 9) : 14

Evaluate

Andrea : Lindsay = 16 : 14

As a percentage, we have

Andrea = 16/(16 + 14) * 100%

This gives

Andrea = 53.33%

Hence, Andrea owns 53.33% of the business after she bought out Dina

<h3>What was the new ratio of ownership once the business was owned by only Andrea and Lindsay?</h3>

In (b), we have:

Andrea : Lindsay = 16 : 14

Simplify

Andrea : Lindsay = 8 : 7

Hence, the new ratio of ownership once the business was owned by only Andrea and Lindsay is 8 : 7

An article was sold for Rs 30
katrin [286]

Answer:

Rs. 32.77

Step-by-step explanation:

  • At a loss of 24% sale price = Rs. 30
  • At a loss of 17% sale price = ?

----------

<u>Finding cost price:</u>

  • Sale price = cost - loss

<u>If cost = x:</u>

  • x - 24% = 30
  • 0.76x = 30
  • x = 30/0.76
  • x ≈ 39.48

<u>SP at a loss of 17%:</u>

  • 39.48 - 17% = 39.48*0.83 ≈ 32.77
