Answer: It decreases


Step-by-step explanation:

Theoretically, let's say n = 15

15 + 15 = 30

Now, let's use 14, because 14<15

14 + 15 = 29

So, the value decreases as n decreases

It has been reported that men are more likely than women to participate in online auctions. In a recent survey, 65% of repondent
kupik [55]

Answer:

Hence, the Female and not participated is \frac{28}{100}=0.28\%

Step-by-step explanation:

Let Total respondents =100

Participated in online action (P)=65

Men (m)=45  and Women (F)=100-45=55

Male and participated (M\; \text{and}\;P)=38

Female and participated (F\; \text{and}\;P)=65-38=27

Male and not participated is 45-38=7

Female and not participated is 55-27=28

Therefore, the Female and not participated is \frac{28}{100}=0.28\%

Hence, the correct option is D.

Find an equation to the line perpendicular to 4x + 36y =80 an goes through the point (3,6) write answer in form y= Mx+b
Veronika [31]

Answer:

\textbf{y = 9x + 21 }\\

Step-by-step explanation:

\textup{Given equation is: $4x + 36y = 80  $}\\\textup{This can be written in the form of $y = mx + a$ as follows}\\$ 36y = -4x + 80 $\\$ \implies y = \frac{80}{36} - \frac{4}{36}x $\\$ \implies y = \frac{-1}{9}x + \frac{20}{9} $\\\textup{This means that the slope of this line is $m = \frac{-1}{9}$}\\

\textup{Then the slope of the line perpendicular to this line would be \textbf{negative reciprocal of m}.}\\$i.e.,$ \textup{Slope of the perpendicular line would be $m_1 = \frac{-1}{\frac{-1}{9}}$}\\$\implies m_1 = 9$\\

\textup{The perpendicular line passes through the point $(3,6)$}\\\textup{Using the \textbf{point-slope formula}, we get:}\\

$$ y - y_1 = m(x - x_1) $$$ \implies y - 6 = 9(x - 3) $\\\textup{After solving this reduces to $y = 9x + 21$ }

A beverage company wanted to see if people in the United States liked their new logo. Which choice best represents a population?
olga55 [171]

Answer:

Every person in the US.

Step-by-step explanation:

  • If a selection of logo artists are asked whether they like or not the new logo, their answer will represent only the opinion of a specific group of artists of the US, and this is <u>not the objective of the beverage company</u>,who wants to know if people from the United States like their logo.
  • If 3,800 children age 5-15 are asked whether they like the logo or not, their opinion will only represent the opinion of some children in the US, whose age is between 5 and 15, and again, this is <u>not the objective of the beverage company</u>,who wants to know if people from the United States like their logo.
  • Finally, the population (which by definition includes all the elements under study, in this case, all the people in the US) will be defined by all people in the US: if the company wants to know if people from the US like their new logo, they must take into account that, the population under study is all people, and not a biased selection of it.
