Particles A and B, of masses 2 kg and
Mkg respectively, are attached to
the ends of a light inextensible
string which passes over a smooth
fixed pulley. B is held at rest on the
horizontal floor and A hangs in
equilibrium.

B is released and each particle starts to
move vertically. A hits the floor 1.5s
after B is released.
The speed of each particle when A hits
the floor is 3.5 ms.
(1) For the motion while A is moving
downwards, find the acceleration of A
and the tension in the string.
li) Find the value of M.

Iq scores for adults age 20 to 34 years are normally distributed according to n(120, 20). in what range does the middle 68% of people in this group score on the test?

The fraction of defective integrated circuits produced in a photolithography process is being studied. a random sample of 300 circuits is tested, revealing 17 defectives. (a) calculate a 95% two-sided confidence interval on the fraction of defective circuits produced by this particular tool. round the answers to 4 decimal places. less-than-or-equal-to p less-than-or-equal-to (b) calculate a 95% upper confidence bound on the fraction of defective circuits. round the answer to 4 decimal places. p less-than-or-equal-to

What are the solutions to the following equation? |m| = 8.5 the value of m is equal to 8.5 and because each distance from zero is 8.5.
