Answer:
1and3
Step-by-step explanation:
The distribution is uniform for 50 ≤ x ≤ 52.
where x = minutes per class.
The probability P(x < 50.6) is the shaded portion of the distribution.
Its value is
(50.6 - 50)/(52 - 50) = 0.3
Answer:
The probability is 0.3 or 30%
The force being exerted by the cord is m(a+g) if the bucket is being accelerated upward.
If T = 70 N, then <span>a=70N/5.2kg−9.8m/<span>s2</span>=3.66m/<span>s2</span></span>is the maximum acceleration that it could have.
Starting from rest, <span>Δy = 1/2a<span>t2</span>→ t = </span>√2Δy/a = <span>√</span>2∗12.5/3.66 = 2.61s
