Next Question
Correct
The best estimate for the lizard population is 450.
marked lizards counted
total lizards counted
=
total marked lizards
estimated lizard population
→
16
200
=
36
p
→ p = 450
F(19)= (3/(19+2)) - sqrt(19-3)
= (3/21) - sqrt(16)
= (1/7) - 4
= (1/7) - (28/7)
= -27/7
= - 3 6/7
Answer:
Step-by-step explanation:
Answer:
Part A:
- angle ACB= 60° (ABC equilateral triangle.)
- Angle ECD=EDC= (180°-32°)/2= 148/2= 74° (sum of angles in a triangle is equal to 180, and triangle ECD is isosceles since it's given that CE=DE.
- x= 180°-(60°+74°)
= 180°-134°
= 46°
x= 46°
Part B:
120°
