Use z scores to compare the given values. The tallest living man at one time had a height of 233 cm. The shortest living man at that time had a height of 91.4 cm. Heights of men at that time had a mean of 174.45 cm and a standard deviation of 6.36 cm. Which of these two men had the height that was more​ extreme?

Answers

Answer 1
Answer:

Answer:

The man with the more extreme height is the man with 91.4 cm.

Explanation:

We have two values: 233 cm and 91.4 cm. The z score for every value is calculated as:

z=(x-m)/(s)

Where x is the given value, m is the mean and s is the standard deviation. So, the z score for every height is:

For 233 cm:

z=(233-174.45)/(6.36)=9.2059

For 91.4 cm:

z=(91.4-174.45)/(6.36)=-13.0582

Then, the more extreme value is 91.4 cm because the z score has the highest absolute value. This is:

For 233 cm

absolute z = 9.2059

For 91.4 cm

absolute z = 13.0582

Finally, The man with the more extreme height is the man with 91.4 cm.

Voltage sources are used to sustain a. the flow of protons
b. chemical reactions
c. resistance
d. the movement of electric charge

Answers

Answer:

d. the movement of electric charge

Explanation:

Voltage source is used to provide constant voltage difference across the ends of a given conductor where it is connected

Now when voltage source is connected across the conductor we can say that due to constant voltage difference there would be a constant current will maintain in the conductor

It is given by

i = (\Delta V)/(R)

now since the voltage difference and resistance both are constant so current will be same in the circuit

So here the flow of charge will remain constant due to voltage source

So correct answer would be

d. the movement of electric charge
the movement of electric charge

How do the locations of frequent earthquakes help support the theory of plate tectonics?a. They shake the top layer of the earth.
b. They create large rifts in the earth.
c. They occur along the edges of the tectonic plates.
d. They alter the topography of the surface of the earth. Please help

Answers

The correct answer for the question that is being presented above is this one: "c. They occur along the edges of the tectonic plates." Frequent Earthquakes occur along the edges of tectonic plates and therefore show that these fault lines are in constant motion. supporting the theory of plate tectonics.

________ is the name for when a director decides where and when performers move and position themselves on the stage.

Answers

Answer:

Blocking/staging

Explanation:

Blocking/staging is the name for when a director decides where and when performers move and position themselves on the stage.

Moreover, Blocking a dream sequence is merely "working on the details of an actor's movements with regard to the camera." We can also reckon of blocking as the dance routines of a dance or a ballet: all the components on the set must move in perfect sync with one another (performers, extras, automobiles, crew, machinery).
