The actual tracking weight of a stereo cartridge that is set to track at 3 g on a particular changer can be regarded as a continuous rv X with the following pdf. f(x) = k 1 − (x − 3)2 2 ≤ x ≤ 4 0 otherwise
(a) Sketch the graph of f(x).
(b) Find the value of k.
(c) What is the probability that the actual tracking weight is greater than the prescribed weight?
(d) What is the probability that the actual weight is within 0.45 g of the prescribed weight? (Round your answer to four decimal places.)
(e) What is the probability that the actual weight differs from the prescribed weight by more than 0.6 g? (Round your answer to four decimal places.)

Many organizations track budgets on a monthly basis. What are
the advantages to tracking budgets on a monthly basis? What
disadvantages might exist for tracking budgets on a monthly basis?
How do monthly budgets help understand what variance the actual
results might have from annual budgeted values?

What is the ratio of the crown's apparent weight (in water) Wapparent to its actual weight Wactual
Take the density of the crown to be \(\rho_{\mathrm{c}} .\) What is the ratio of the crown's apparent weight (in water) \(W_{\text {apparent }}\) to its actual weight \(W_{\text {actual }} ?\)
Express your answer in terms of the density of the crown \(\rho_{\mathrm{c}}\) and the density of water \(\rho_{\mathrm{w}}\)
\(\frac{W_{\text {apparent }}}{W_{\text {actual }}}=1-\frac{\rho_{w}}{\rho_{c}}\)

SLIDING OSCILLATIONS 3 My Notes A block weighing 273 g slides
along a frictionless track at a speed 8.9 cm/s. It then attaches to
a spring-bumper with an electromagnetic device so that the block
attaches to the bumper. The bumper has a mass of 115 g, and the
spring has a stiffness of 1110 kg/s2 and an equilibrium length of
9.5 cm. After the spring compresses and returns to its original
length, the magnet turns off and the block launches...

Potassium has a density of 0.86 g/cm^3, an atomic weight of
39.0983 g/mol, and contains 0.012% of Potassium-40 which is
radioactive by beta-decay with a half-life of 1.25x10^9 years.
a. What is the total and average binding energy of
potassium-40?
b. If the average mass of potassium within the human body is
about 140 g, estimate the average activity (in bq) of [40,19] K in
the body.
