The Awnser for the exact value is 7x + 3
Refer to the diagram below, which provides a plan view of the problem
Because each player applies the same force, F, the angle between the force and the direction of motion is (1/2)*25° = 12.5°.
Because the sled moves with constant velocity, the sled is in dynamic equilibrium, and
2F cos(12.5°) = 1140 N
1.9526 F = 1140
F = 583.84 N
Answer: 583.8 N (nearest tenth)
10 and12 is the correct answer
Answer:
(+,0)
Step-by-step explanation:
because the graph of the inequality
Answer: 0.16
Step-by-step explanation:
Given that the run times provided are normally distributed ;
Mean(x) of distribution = 3 hours 50 minutes
Standard deviation(s) = 30 minutes
The probability that a randomly selected runner has a time less than or equal to 3 hours 20 minutes
3 hours 20 minutes = (3 hrs 50 mins - 30 mins):
This is equivalent to :
[mean(x) - 1 standard deviation]
z 1 standard deviation within the mean = 0.84
z, 1 standard deviation outside the mean equals:
P(1 - z value , 1standard deviation within the mean)
1 - 0.8413 = 0.1587
= 0.16
