Answer:
<em>The predicted sales are 7.46 billion dollars</em>
Step-by-step explanation:
<u>Function Modeling</u>
We are given two points that represent the Online jewelry sales. The two points are ( 2003 , 2 ) and ( 2013 , 5.64 ). The second coordinate is expressed in billion dollars. To better represent the function, let's count the time not in absolute years, but in years after 2003. The points now are ( 0 , 2 ) and ( 10 , 5.64 ).
The function to represent the sales (S) will be a line, which general equation is
Plugging in the points
Operating and rearranging
Now we use the model to predict the online sales for 2015, or t=15
The predicted sales are 7.46 billion dollars
The ordered pair (7,2) is viable and Option B is the correct answer.
<h3>What is Relationship ?</h3>
Relationship between variables defines the way one variable is dependent upon the other variable.
It is given that x is the number of visitors and y is the number of winners,
It has to be seen and chosen that which ordered pair makes sense
The ordered pair is viable if the no. of visitor is positive and more than the number of winners.
Therefore ordered pair (7,2) is viable and Option B is the correct answer.

Answer:
We are 95% confident that the true proportion of young adults in the population who skip breakfast is between .20 and .27.
Step-by-step explanation:
A 95% confidence interval for the proportion of young adults who skip breakfast is .20 to .27. Which of the following is a correct interpretation of this 95% confidence interval?
We take a sample, and infer for the entire population.
So the interpretation is that we are 95% sure that the true proportion of all young adults who skip breakfast is between 0.20 and 0.27.
So the correct answer is:
We are 95% confident that the true proportion of young adults in the population who skip breakfast is between .20 and .27.

Step-by-step explanation:
La amplitud entre cada rueda de la fortuna es 18 °
La rueda de la fortuna es de forma circular, lo que significa que el ángulo total es de 360 °
Esto significa que el número total de amplitud entre cabinas en la rueda de la fortuna es <em>360°/18° = 20
</em>
<em>esto significa que el número total de cabañas 20</em>
