To determine the number of squirrels in a conservation area a researcher cashers tags and releases 114 squirrels you later catch
Ede4ka [16]

Answer:

336 squirrels

Step-by-step explanation:

-This is a Mark-Recapture method.

-The population is estimated using the formula:

N=\frac{MC}{R}

where:

  • N-is the estimated population size.
  • M-is the number of individuals tagged
  • C- is the total number captured the second time(both tagged and untagged)
  • R-is the total number of tagged individuals recaptured.

#We substitute our values as follows to estimate N:

N=\frac{MC}{R}\\\\=\frac{114\times 97}{33}\\\\=335.0909\approx336

Hence, there are approximately 336 squirrels in the conservation area.

*population is always rounded up to the next whole number.

Mary wants to apply a strip of wallpaper along the walls just below the ceiling. If the room is a 14 ft by 12 ft rectangle, then
Yuliya22 [10]

Answer:

<h2>52 ft.</h2>

Step-by-step explanation:

In this case, we need to calculate a perimeter, which is the sum of all sides of the rectangle.

So, rectangles has opposite sides equal, therefore, the perimeter should be:

P=2 (L+l); having L as the larger side.

P=2(14+12)\\P=2(26)\\P=52

Hence, the strip of wallpaper needs to be as least 52 ft.

) Alon started in 60% of his team's basketball games this season. He started a total of 12 games. About how many games did Alon'
kvv77 [185]

Answer:

D

Step-by-step explanation:

Let x = total number of basketball games that was played by the team this season.

Alon started in 60% of his team’s basketball games this season. This means that he started in a total number of 60 percent of x basketball games this season.

60% of x basketball games this season = 60/100 × x

= 0.6×x = 0.6x

From the information given, Alon started a total of 12 basketball games this season. Therefore,

0.6x = 12

x = 12/0.6 = 20
