An object is launched straight upward from a platform. Its height above ground is h(t) = h0+ v0t ? 16.1t2 where h is in feet and t is in seconds. The graph of h is shown below. Find both unknown constants, accurate to 1 decimal place. Solution h(t) = h0 + v0t - 16.1t^2 As can be seen, the maximum height is reached at t = 2.5 : So, -b/(2a) = 2.5 -v0 / (2*-16.1) = 2.5 v0 / (32.2) = 2.5 v0 = 2.5 * 32.2 v0 = 80.5 ---> Answer for v0 When t = 1 , h = 90 90 = h0 + 80.5*1 - 16.1*1^2 h0 = 90 - 80.5 + 16.1 h0 = 25.6 So, the constants are : v0 = 80.5 AND h0 = 25.6.

An urn contains 12 white, 5 yellow and 13 black marbles. A marble is chosen at random from the
urn, and it is noted that is not one of the black marbles. What is the sample space in view of this
knowledge? What it the probability that it is yellow?
Solution
probability of the ball being yellow = 5/12+5 =5/17 hope my answer is correct and
please appreciate my help by awarding me karma points..
An SRS of 18 recent birth records at the local hospital was selected.pdf
An SRS of 18 recent birth records at the local hospital was selected. In the sample, the average
birth weight was 119.6 ounces and the standard deviation was 6.5 ounces. Assume that in the
population of all babies born in this hospital, the birth weights follow a Normal distribution, with
mean ?. Reference: Ref 18-1 The standard error of the mean is
Solution
for a small sample, you should use the t-dist. with 18-1=17 deg. freedom. From the t-table,
t=2.110 cuts off .025 in each tail. So ME is 2.11 (6.5)/sqrt(18)=3.233 ounces.

An optical source has a spectral width of 1300 nm. What type of optical source is it likely to be?
Solution
Fiber optics are the communication medium through which the signals can be send and also the
signals can be received since the signals which have to sent have to be send as fast as possible
and this can be achived by this fiber optics. Multimode fiber is one which uses a wideband
source by which the signal can be sent at very faster rate.The wider band source has a spectral
width of 1300 nm because it has low loss. that is it transmits the wave signal with low loss and
with efficient output..

An ordinary deck of 52 cards is shuffled. What is the probability that the top four cardshave
(a) different denominations?
(b) different suits?
Solution
a) P(diff deno)=(52*48*44*40)/(52*51*50*49)=0.6761 b) There are 24 different
ways to get 4 cards of different suits (H,S,C,D or H,S,D,C, or H,C,S,D...). Each combination is
equally likely, so we’ll find the probability of one of them, and then multiply it by 24 to get the
answer. The probability of H,S,C,D is (13/52) * (13/51) * (13/50) * (13/49) = 0.0044. So
multiply by 24 to get 0.105.
An object is thrown with an initial velocity of 14 ft per second. It.pdf
An object is thrown with an initial velocity of 14 ft per second. Its height is given by h= -14t^2 +
56 at time t seconds. After how many seconds does it hit the ground?
Solution
we have...
speed = 14 ft/second
distance or h = -14t^2 + 56
also we know that ...Distance = speed * time
putting the above values in the formula..we get
-14t^2 + 56 = 14 * t
taking common 14 from LHS ,,we get
14 ( -t^2 + 4) = 14 * t
divide both sides by 14 and we get ...
-t^2 + 4 = t
or 0 = t^2 + t - 4
solve the value of t by discriminent and you get the value of t
and put the value of t in formula ..distance = speed * time
and you get distance also.,..
An NMOS transistor with kn=4 mAV2 and Vt=.5 V is operated with Vos=.pdf
An NMOS transistor with kn=4 mA/V2 and Vt=.5 V is operated with Vos=1 V. At what value of
VDS does the transistor enter the saturation region? What value of ID is obtained in saturation?
Solution
NMOS will enter saturation when, Vds = Vgs -Vt = 1 - 0.5 = 0.5V
Id = Kn * (Vgs-Vt)2 in saturation
= 4 * (0.5)2 = 1mA
so Id = 1mA.

An object is launched straight upward from a platform. Its height ab.pdf
- 1. An object is launched straight upward from a platform. Its height above ground is h(t) = h0+ v0t ? 16.1t2 where h is in feet and t is in seconds. The graph of h is shown below. Find both unknown constants, accurate to 1 decimal place. Solution h(t) = h0 + v0t - 16.1t^2 As can be seen, the maximum height is reached at t = 2.5 : So, -b/(2a) = 2.5 -v0 / (2*-16.1) = 2.5 v0 / (32.2) = 2.5 v0 = 2.5 * 32.2 v0 = 80.5 ---> Answer for v0 When t = 1 , h = 90 90 = h0 + 80.5*1 - 16.1*1^2 h0 = 90 - 80.5 + 16.1 h0 = 25.6 So, the constants are : v0 = 80.5 AND h0 = 25.6
