Answer:
5
Step-by-step explanation:
(0.000064)^5/6 divided by (0.00032)^6/5
(0.00032)^6/5=(0.000064)
and
(0.000064)^6/5=(0.00032)
so now we have (0.00032) divided by (0.000064)
which is 5!
hope this helps!
Considering that we have the standard deviation for the sample, the t-distribution will be used, and the critical value is t = 2.6682.
<h3>When should the t-distribution and the z-distribution be used?</h3>
- If we have the standard deviation for the sample, the t-distribution should be used.
- If we have the standard deviation for the population, the z-distribution should be used.
In this problem, σ is not known, hence we get the standard deviation of the sample from the histogram and the t-distribution is used.
Using a t-distribution calculator, considering a <em>confidence level of 99%</em> and 56 - 1 = <em>55 df</em>, the critical value is t = 2.6682.

Answer:
39 or 1/39
Step-by-step explanation:
You need to divide these but it depends on how you divide them
Answer:
x²=5-x
x²+x-5=0
1x²+1x²-5=0
[ax²+bx²+c=0]
∆=b²-4ac
∆=1²-4(-5)(1)=1+20=21
x=(-b±√∆)/2a
x=(-1±√21)/2
meaning:
x=(-1+√21)/2 or x=(-1-√21)/2
