The average of the following set of measurements is 20°C.
To find the average of the given set of measurements
Given:
Set of measurements = 27°C, 12°C, 31°C, 19°C, 23°C, 11°C, 17°C
Number of Observations = 7
Average = Sum of observations/Total number of observations
Sum of observations = 27°C+12°C+31°C+19°C+23°C+11°C+17°C
= 140
Total number of observations = 7
Substitute the values in the formula
= 140/7 = 20°C
Therefore, the average of the following set of measurements is 20°C

Inner core was found to be solid after observing the motion of P waves.
Explanation:
Seismologist Inge Lehmann, studied the seismic waves of an earthquake and discovered about inner core in the mantle layer of Earth. She States that there is a boundary of discontinuity between the outer and inner core of Earth.
She studied the travel of secondary and primary waves during an earthquake and how it flows at different shells of Earth's layer which helped her in finding about the inner core of mantle. She observed that the inner core is a solid layer inside the molten layer of outer core
Extensively drug-resistant
tuberculosis is a form of tuberculosis which is caused by bacteria that are
resistant to some of the most effective anti-TB drugs such as isoniazid and
rifampin. This form of tuberculosis occurs due to an individual’s mismanagement
of multidrug-resistant TB. Treatment for extensively resistant TB would include
medication with at least two drugs to which the TB is susceptible.
I believe it would be the bottleneck effect. hope that helps =)
