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.

a scalene right triangle has a hypotenuse with a length of 50 cm. The length of one leg is twice the length of the other. What a

zheka24 [161]

Let
x------------> The length of one leg
y------------> The length of second leg

we know that
H=50 cm
x=2y
applying the Pythagorean theorem

H²=x²+y²--------> 50²=(2y)²+y²---------> 2500=4y²+y²-----> y²=2500/5
y=√500--------> y=22.4 cm
so
x=2y--------> x=2*22.4--------> x=44.8 cm

the answer is
the lengths of the legs of the triangle are
44.8 cm
and
22.4 cm
