Biologists collected a random sample of 850 fish and 25 of them had been previously tagged. 850 : 25 = 34. It means that about 1/34 of all the fishes in the lake had been tagged. Therefore 600 * 34 = 20,400.
Answer: Based on this experiment, in the lake lives 20,400 fishes.

Answer:

b. inelastic

c. Yes - it decreased

Explanation:

Elasticitiy of demand measures the responsiveness of quantity demanded to changes in price.

Elasticity of demand = percentage change in quantity demanded/ percentage change in price

The absolute value is 0.5

If the absolute value of the coffiecnet of elasticity of demand is less than one, demand is inelastic.

Your $6100 investment grows to $12200 over the course of 9 years compounded quarterly. what interest rate did you receive on you
k0ka [10]
The formula is
A=p (1+r/k)^kt
A future value 12200
P present value 6100
R interest rate ?
K compounded quarterly 4
T time 9 years

Set the equation and solve for r (interest rate)
12200=6100 (1+r/4)^(4×9)
Divide both sides by 6100
12200/6100=(1+r/4)^(36)
2=(1+r/4)^(36)
Take the root of 36 for both sides
2^(1/36)=1+r/4
R= (2^(1/36)-1)×4
R=(2^(1÷36)−1)×4
R=0.0778×100
R=7.78%

Hope it helps!
