Answer:
10 units
Step-by-step explanation:
Using the distance formula above,
distance between the 2 points
![= \sqrt{[0 - ( - 8)]^{2} + (7 - 1)^{2} } \\ = \sqrt{(0 + 8)^{2} + 6^{2} } \\ = \sqrt{ {8}^{2} + 36} \\ = \sqrt{64 + 36} \\ = \sqrt{100} \\ = 10 \: units](https://tex.z-dn.net/?f=%20%3D%20%20%5Csqrt%7B%5B0%20-%20%28%20-%20%208%29%5D%5E%7B2%7D%20%2B%20%287%20-%201%29%5E%7B2%7D%20%20%7D%20%20%5C%5C%20%20%3D%20%20%5Csqrt%7B%280%20%2B%208%29%5E%7B2%7D%20%2B%206%5E%7B2%7D%20%20%7D%20%20%5C%5C%20%20%3D%20%20%5Csqrt%7B%20%7B8%7D%5E%7B2%7D%20%20%2B%2036%7D%20%20%5C%5C%20%20%3D%20%20%5Csqrt%7B64%20%2B%2036%7D%20%20%5C%5C%20%20%3D%20%20%5Csqrt%7B100%7D%20%20%5C%5C%20%20%3D%2010%20%5C%3A%20units)
Answer:
Kindly check explanation
Step-by-step explanation:
Given the expression : -600 - (-50) as explorer climbs back to the surface :
In terms of elevation :
-600 represents the initial position below the surface.
The Change in elevation from his initial position is - 50 (though the climber is moving towards the surface) ; the negative sign depicts that he is still below the surface.
Hence,
-600 - (-50)
= - 600 + 50
= - 610
Hence, the explorer moved an elevation of - 50 in the upward direction from his initial position of - 600 ; Hence, his position is - 610 ; which is still beneath the surface
The correct answer is A. The 200 randomly selected students
Explanation:
In most studies, the complete population is not surveyed or studied instead, a specific number of individuals are selected, this group is known as the sample. Additionally, the sample represents the population, and due to this, their answers are used to make inferences about all the population.
According to this, the population is all the students in the school, while the sample is the 200 randomly selected students because this is the group that is going to be studied to make conclusions and inferences about all the population.
10.4 - 2 = 8.4
1/4(8.4) = 2.1........2 + 2.1 = 4.1 <==
