The number of hours a light bulb burns before failing varies from bulb to bulb. The distribution of burnout times is strongly sk

ewed to the right. The Central Limit Theorem says that :_________
a. the average burnout time of a large number of bulbs has a distribution that is close to Normal.
b. the average burnout time of any number of bulbs has a distribution that is close to Normal.
c. as we look at more and more bulbs, their average burnout time gets ever closer to the mean for all bulbs of this type.
d. the average burnout time of a large number of bulbs has a distribution of the same shape (strongly skewed) as the distribution for individual bulbs.
e. the average burnout time of any number of bulbs has a distribution of the same shape (strongly skewed) as the distribution for individual bulbs.

8 1/2 x 2 3/4 x 2/3= 12
Aloiza [94]

Answer:

155.25= 12

Step-by-step explanation:

              17/2*2*1/2 = 12

                 17*1/2 = 12

8 1/2          17/1* 1/2

8*2+1          17*1/1*2  

   2             17*1/1*2

16+1               17/1*2

  2                  17/2

17                     8.5=12

at 111111:55\text{ p.m.}55 p.m.55, start text, space, p, point, m, point, end text, thomas ties a weight to the minute hand of a
Ahat [919]

The trigonometric function's formula, which simulates the torque (tau) that the weight applied t minutes after Thomas attached it is

3 Sin (\frac{2\frac{22}{7} }{60} (t-51))

The angular speed of the minutes hand is

w = \frac{2 (\frac{22}{7}) }{60} rad/min

Following the application of weight, the torque as a function of time t is,

t= t_{0} sin (w (t-5) min)\\ = (3 Nm) sin ((\frac{2 (\frac{22}{7} }{60} ) rad/min (t-5) min)

= (3 Nm) sin ( \frac{2 (\frac{22}{7} }{60} (t-5) rad ) \\= 3 sin (\frac{2 \frac{22}{7} }{60} (t-5)

<h3>What is torque ?</h3>

Torque, which is also known as the moment of a force, is the propensity of a force to rotate the body to which it is applied. Force (F) x Distance (r) = Torque is how torque is calculated. The distance (r) between the pivot point and the force's action point. A vector quantity is a torque. As a vector quantity, torque always has a direction that is perpendicular to the plane that contains the vectors of force and displacement.
