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

Answer:

The measure of the third angle is equal to 34°

Step-by-step explanation:

Given that,

The measure of angle 1 is 50°.

The measure of angle 2 is 96°

We need to find the measure of the third angle. We know that the sum of angles of a triangle is equal to 180°. So,

x+50+96=180

x+146=180

x = 180-146

x = 34°

So, the measure of the third angle is equal to 34°.
