The formula for half-life is:

A is the amount remaining, P is the initial amount, t is the time that has passed, and h is the half-life of the substance. Plug in the values that you know and solve:

Rounded to the nearest whole number, the density of the substance was about 13<span>mg / cm².</span>
Answer:
Option (B) a 95% confidence interval does not include the hypothesized value of the parameter
Step-by-step explanation:
Alpha, α = 0.05
We conduct a hypothesis test at 5% significance level.
The null hypothesis will be rejected when
Option (B) a 95% confidence interval does not include the hypothesized value of the parameter
- When a 95% confidence interval is constructed,it contains all the possible values for the parameter being estimated.
- If the value of the parameter stated in the null hypothesis is contained in the 95% confidence interval, then we fail to reject the null hypothesis 0.05 level and accept it.
- If the value stated in the null hypothesis is not in the interval, then we fail to accept the null hypothesis and reject the null hypothesis at the 0.05 level.
Step-by-step explanation:
A/B=5/7 , B/C=6/12
Taking B=12×7=84, we get
A=12×5=60, C=7×6=42
Hence,
60:84:42. Answer
The answer is 4195.6. Hope this helps you :)
Answer:
The edge lengths are 3 for all of them. Radical cubed 27 is also 3.
Step-by-step explanation:
27/ 3 = 9. The square root of 9 is 3. So 3 * 3 * 3 = 27. For the bottom answer, it is 3 since 3 * 3 * 3 = 27.
How simple is this answer. I don't understand your problem.
