Answer:12 mph
Step-by-step explanation:
Answer:
21 m
Step-by-step explanation:
= 3 - 3cos x - 2(1- cos^2 x)
= 2cos^2 x - 3cos x + 1
=(cos x -1)(cosx - 1/2)
now cos x = 1 or cos x= 1/2
draw a graph we get = + ve values
hence .. 0 ,180,360 and 60,240, degrees in range x<2pi
Answer:
And using the normal standard distirbution or excel we got:
Step-by-step explanation:
Let X the random variable that represent the resistance for resistors of a population, and for this case we know the distribution for X is given by:
Where
and
We are interested on this probability
And the z score formula is given by:
Using this formula we got:
And using the normal standard distirbution or excel we got:
