If &lt;ABC measures 100 and is inscribed in a circle O. find &lt;BAO and &lt;BCO​
satela [25.4K]

Answer:

<BCO​ = <BAO​ = 20degrees

Step-by-step explanation:

If <ABC measures 100 and is inscribed in a circle O. find <BAO and <BCO​

To get <BAO and <BCO​, we need to get <AOC first.

From the figure, it can be seen that triangle ABC is an isosceles trinagle. Hence;

<BAC + <BCA + 100 = 180

Since <BAC = <BCA

<BAC + <BAC = 180 - 100

2<BAC = 80

<BAC = 80/2

<BAC = 40

Also;

<BAO = <BCO​ and <BAO = <BAC/2

<BAO = 40/2 = <BCO​

Hence <BCO​ = <BAO​ = 20degrees

Find the critical value from the Studentized range distribution for H0: μ1 = μ2 = μ3 = μ4 = μ5, with n = 35 at α = 0.01. Provide
Aleonysh [2.5K]

Answer:

t-value = 2.441

Step-by-step explanation:

Let's assume that this is a one-tailed test to calculate the critical value, the process is this:

  • Calculate alpha (α): α = 1 - (confidence level / 100) , but we already have this α=0.01
  • Find the critical probability (p*): p* = 1 - α/2  = 1-0.005=0.995
  • Then, the critical value would be shown as a t statistic, but for this we need:

degrees of freedom (df)= n-1=35-1=34

  • The critical t statistic (t*) or critical value is the t-value having degrees of freedom equal to 34 and a cumulative probability equal to 0.995.

From the attached table we can see:

t-value = 2.441
