Answer:
And we can use the normal table and the complement rule we got:
Step-by-step explanation:
For this case we have the following parameters given:
We select a ample size of n=49. And we want to find this probability:
And for this case is a right tail probability and we can use the z score formula given by:
And replacing we got:
And we can use the normal table and the complement rule we got:
Yes you have the right idea. You find the derivative to get the velocity function and then determine when the velocity is zero. That turns out to be at t = 2 and t = 6. Both are correct. The final answer is correct.
The only flaw I see is that you wrote
x'(t) = 3y^3 - 24t + 36
on line 2 when it should be
x'(t) = 3t^2 - 24t + 36
Other than that it looks perfect.
2x +6x = 8x
6-1 = 5
8x+5 is the answer
X 2^(-x) 4^(x+3)
-3 8 1
-2 4 4
-1 0 16
0 1 64
1 0.5 256
2 0.25 1024
3 0.125 4096
The solution is x = -2 because both functions return the same value, i.e. 4.
Density of fish = number of fish / volume
0.2 = n / 20
n = 20*0.2 = 4
there are 4 fish in the tank.
