A total of 440 students took part in the survey. Each student makes up 0.8181818182% of the central angle of the circle graph. You get to this number by dividing 360 degrees by 440 students. Then you simply multiply this number by 110 students (who liked the program).

0.8181818182%*110=90 degrees

The average college lecture hall (auditorium) can seat 60 students with a standard deviation of 21. Assume that a total of 60 le
fiasKO [112]

Answer:

The standard deviation of the sample mean is  \sigma _ {\=  x } = 2.711

Step-by-step explanation:

From the question we are told that

   The mean is  \= x  =  60

    The standard deviation is  \sigma  =  21

     The sample size is n  =  60

Generally the standard deviation of the sample mean is mathematically represented as  

               \sigma _ {\=  x } =  \frac{\sigma  }{\sqrt{n} }

substituting values

               \sigma _ {\=  x } =  \frac{ 21 }{\sqrt{60} }

               \sigma _ {\=  x } = 2.711

When solving negative one over eight (x + 35) = −7, what is the correct sequence of operations?
Fantom [35]
The answer is <span>Multiply each side by −8, subtract 35 from each side

</span>- \frac{1}{8}(x+35)=-7
<span>
Multiply each side by -8:
</span>(-8)(- \frac{1}{8})(x+35)=(-8)(-7) \\  \\ &#10;1(x + 35) = 56 \\ &#10;x + 35 = 56
<span>
Subtract 35 from each side:
</span>x + 35 -35 = 56-35 \\  \\ &#10;x + 0 =21 \\  \\ &#10;x = 21<span>

What are the missing reasons in the two-column proof?
Nesterboy [21]

Reasons:

1. Because, MO cuts Angle PMN in two equal parts.

2.As ∠PMN is cut in to equal parts thus:

∠PMN = ∠NMO + ∠PMO, where these two parts (∠NMO, ∠PMO) are equal.

3. Both are the same, common you can say..

4. Because, MO cuts Angle PON in two equal parts.

5. As ∠PON is cut in to equal parts thus:

∠PON = ∠NOM + ∠POM, where these two parts (∠NOM , ∠POM) are equal.

6. From the above statements, we have:

= ∠NMO + ∠PMO (Proved)

= ∠NOM + ∠POM (Proved)

= MO = MO (Proved)

Thus, ∆PMO ≅ ∆NMO, by AAS rule

Define jurisdiction.
timama [110]
The definition of jurisdiction as given in the choices would be authority over something. You have jurisdiction if you are free to make decisions on the matter. 

Courts that try cases are called courts of original jurisdiction - which are usually trial courts.
