The probability that the sample mean would differ from the population mean by less than 655 miles in a sample of 79 tires if the manager is correct is = 0.9805.
<h3>
What is the calculation for the above?</h3>
P (
< 655) ≡ P [ |( - μ)/√(σ²/n) | <655/√(6,220,036/ 79)]
= P (| Z | < 3.55)
= P - 3.55 < Z < 3.55) Using the z -score table
= 0.9998 - 0.0193
= 0.9805

By Newton's second law, the net force on the object is
∑ F = 10.0 N + F = (7.0 kg) (1.0 m/s²)
where F is the unknown force. Since the object is accelerating to the east, F must be acting in the same or opposite direction as the known force that is also directed eastward. Solve for F :
10.0 N + F = 7.0 N
⇒ F = - 3.0 N
which is to say, F has magnitude 3.0 N and points toward the west.

Answer:
1/6
Explanation:
The circumference of a circle is denoted by: C = 2πr, where r is the radius. Here, we see that the radius is 1, so plug this in:
C = 2πr
C = 2π * 1 = 2π
We see that arc AB has length π/3, so to find the fraction of the circumference this is, divide π/3 by 2π:
(π/3) ÷ 2π = (π/3) * (1/2π) = 1/6
Thus, the answer is 1/6.
Answer:
O Paul Robeson was a talented man whose reputation was hurt by his political beliefs.
Explanation:
In the given passage, the speaker talks about Paul Robeson who was a famous African American athlete, actor, singer, etc. among many other expertise. But despite all his achievements and popularity, his political opinion led to a huge blow in his popularity.
Therefore, we can say that while Robeson was famous in almost all sides, his critical position of admiration for the Soviet Union, an enemy of the United States, led to his 'fall' from being popular to becoming disliked by the people. This shows how one's reputation can be hurt by one's political beliefs, just like Paul Robeson's was.
Thus, the correct answer is the fourth option.
