Answer:
d) Both blocks experienced equivalent energy loss due to friction
Explanation:
As stated in the question, two tractors are pulling two identical stone blocks the same distance across similar surfacesAdditionally, block A moves at double the speed of block B when completing the race
This implies both blocks suffer from comparable friction loss
Moreover, we understand that
Energy loss from friction is 
Thus, the friction loss should be identical for both blocks
therefore, option d is the accurate choice 
Let’s determine the actual mean
First, we sum all the values
87+46+90+78+89 = 390
Then, we divide 390 by the count of numbers present.
390/5 = 78
Thus, the mean is 78
Emi did not manage to calculate the difference
D1,..,d9 = 0,0,2,2,2,3,4,6,8 //there are 9 values, presented in ascending order
Q2 (median) = d5 = 2 //middle value
Q1 = (d2+d3) / 2 = (0+2)/2 = 1
(Q1 represents the median of d1,d2,d3,d4, but as there is no singular middle element among four, the average is computed)
Q3 = (d7+d8) / 2 = (4+6)/2 = 5
interquartile range = IQR = Q3 - Q1 = 5 -1 = 4
final answer: 4
Define x as the first mile marker, thus x + 1 corresponds to the second mile marker. This can be expressed as x + (x + 1) = 561, which simplifies to 2x + 1 = 561. Therefore, 2x equals 560, leading to x being 280. Consequently, the first mile marker is 280, and the second mile marker is 281.
Answer:
Step-by-step explanation:
The probability of an event quantifies the likelihood of that event occurring.
Definition: The probability of an event is given as
1. An event that is sure to occur (Number of favorable outcomes = Total number of outcomes) has a probability of 1.
2. An event that is impossible (Number of favorable outcomes = 0) has a probability of 0.
3. If there's a possibility that an event can occur, its probability will fall between 0 and 1.
