9.6 yes because it can be expressed as a fraction
Answer:
Distance ≈ 14.8
Step-by-step explanation:
<u>Calculate the distance (d) using the distance formula</u>
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (- 4, 6) and (x₂, y₂ ) = (3, - 7)
Hope this helps!!!!
I would say A, because RST = VUT. Also, that would make the most sense... That is just me...
Assume that a step to the north is in the positive direction and a step in the south is in the negative direction.
Then,

and

After 1 hour of independent steps,

and

Therefore, by Central Limit Theorem, the distribution of the random walk is normal with a mean of 0 cm and a standard deviation of 17.32 cm. He is expected to be somewhere around his starting point after 1 hour.
