a flower bed is in the shape of a triangle with one side twice the length of the shortest side and the third side is 19 feet mor
Neporo4naja [7]

Let's assume

shorter side as x

so, first side =2x

third side =x+19

now, we can find perimeter of triangle

perimeter of any triangle is

first side + shortest side + third side

so, we get

P=2x+x+x+19

we are given perimeter=187

so, we can set it to 187

and then solve for x

187=2x+x+x+19

187=4x+19

4x+19-19=187-19

4x=168

x=42

so,

shortest length is x=42 feet

First side =2x=2*42=84feet

third side =x+19=42+19=61 feet

so, dimensions are

first side is 42 feet

second side is 84 feet

third side is 61 feet................Answer

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.
