Answer:
The probability of rolling 4 is 1/6.”
Answer:
= h
Step-by-step explanation:
Just divide both sides by pi r^2 to cancel it form the right side and you will be left with:
= h
6 ≤ 4 + (-2x)
6 (-4) ≤ 4 - 2x - 4
4 and 4 cancels out
2 ≤ -2x
-1≥x
When you divide by a negative number, the inequality sign turns to the other side.
Answer:
The sample size should you gather to achieve a 0.45 hour margin of error
(n) = 411
Step-by-step explanation:
<u>Step(i)</u>
Given data a preliminary sample of 35 bacteria reveals a sample mean of x = 74 with a standard deviation of s = 5.4
Given the margin of error = 0.45
The degrees of freedom = n-1 = 35-1=34
The 90% of level of significance of t- distribution
t₀.₁₀ = 1.69 ( from table at 34 degrees of freedom at 0.10 level of significance)
<u>Step(ii)</u>
Margin of error = 1.69S / √n
Given data sample standard deviation S =5.4 hours.
margin of error = o.45
Margin of error =
use this formula to determine the sample size
√n = 1.69X5.4/0.45
√n = 20.28
squaring on both sides n= 411.27≅411
<u>Conclusion</u>:-
The sample size should you gather to achieve a 0.45 hour margin of error
(n) = 411
