With the help of distance or displacement, we can find how far does he walk from his starting to his ending point.
Distance: It is a scalar quantity that refers to "how much ground an object has covered" during its motion.
Displacement: It is the distance and direction of the shortest path
from the starting point to the ending point, regardless of the path followed to get there.
If the starting and the initial position are same, means he did not move. The distance and displacement is zero. He is in rest.
To find the total path he covers from starting point to ending point, the we calculate the distance, by using the formula:
where,
s = speed of the object
t = total time he takes to move from starting point to ending point.
To find the shortest path between the starting point and the ending point, we find the displacement, by using the formula:
where.
= starting point
= ending point
By finding distance or displacement we can calculate the total path length he covered and the shortest distance between the two points respectively.

#SPJ4
Answer:
The mean of the distribution = 76.05
The standard deviation of this distribution = 5.159
Step-by-step explanation:
Given:
The true proportion of voters in the county who support a new fire district is =0.65
sample size n=117.
Solution:
<u>The mean of the distribution:</u>
The mean of the distribution is given by n * p
where
n= sample size
p= probability of success on an individual trial.
Substituting the values , we get
Mean=117 *0.65
Mean=76.05
<u>Standard deviation of this distribution:</u>
#1: y is greater than or equal to 1/2x-1
#2: y < -3x+1
Answer:
13 hours
Step-by-step explanation:
At the same rate of speed, Hong can expect to take 936/576 times the time in order to drive 936/576 times the distance.
... (936/576)·8 hours = 13 hours
Answer:
D. Theoretical
Step-by-step explanation:
The probability is based on the number of marbles in the bag. It is the theoretical probability. It is the likelihood that a yellow marble will be picked
