Answer:

35 + 145 = 180

62 + 118 = 180

105 + 75 = 180

122 + 58 = 180

Step-by-step explanation:

Angles that make straight angles are angles which add to 180 degrees.

35 + 145 = 180

62 + 118 = 180

105 + 75 = 180

122 + 58 = 180

The average and standard deviation of a measurement is 15.0 ± 5.0. if 100 students measured the value, how many would you expect
AURORKA [14]

Solution: We are given:

\mu=15, \sigma=5

Using the empirical rule, we have:

\mu \pm \sigma covers 68% of data.

Also the percentage of values below mean = Percentage of values above mean = 50%

Now, let's find the z score for x=20

z=\frac{20-15}{5}=1

Therefore, the percentage of values greater than 1 standard deviation above mean 50\% - \frac{68\%}{2} =50\%-34\%=16%

Expected number of students = 16% of 100 = 16
