Answer with explanation:
To test the Significance of the population which is Normally Distributed we will use the following Formula Called Z test


→p(Probability) Value when ,z=3.756 is equal to= 0.99992=0.9999
⇒Significance Level (α)=0.01
We will do Hypothesis testing to check whether population mean is different from 25 at the alpha equals 0.01 level of significance.
→0.9999 > 0.01
→p value > α
With a z value of 3.75, it is only 3.75% chance that ,mean will be different from 25.
So,we conclude that results are not significant.So,at 0.01 level of significance population mean will not be different from 25.
Answer:
s(2) = √7
Step-by-step explanation:
s(2) = √(3[2] + 1) = √7
Answer:
= 3.75
Step-by-step explanation:
The n th term of a geometric sequence is
= a₁
where a₁ is the first term and r the common ratio
Here a₁ = 30 and r =
, thus
= 30
= 30 ×
=
=
= 3.75
Answer:
8x^3+2x^2+6x
Step-by-step explanation:
2x(4x^2+x+3)
using distribution -
8x^3+2x^2+6x

Answer:
Step-by-step explanation:
We can use the decay equation:

- M(0) is the initial mass
- M is the mass after t (1000 days) time
- λ is the decay constant
But:

So, we can rewrite the initial equation:

Now, we just need to solve it for t(1/2):
