Your grandfather clock is a simple pendulum with a length of
0.994 m. If the clock loses 3 min in a week, how should you adjust
the length of the pendulum so that it can properly keep time?

A production manager at a wall clock company wants to test their
new wall clocks. The designer claims they have a mean life of 16
years with a variance of 16. If the claim is true, in a sample of
48 wall clocks, what is the probability that the mean clock life
would differ from the population mean by greater than 0.7 years?
Round your answer to four decimal places.

A production manager
at a wall clock company wants to test their new wall clocks. The
designer claims they have a mean life of 1717 years with a variance
of 1616.
If the claim is true,
in a sample of 4343 wall clocks, what is the probability that the
mean clock life would be greater than 17.917.9 years? Round your
answer to four decimal places.

A production manager at a wall clock company wants to test their
new wall clocks. The designer claims they have a mean life of 1414
years with a variance of 1616.
If the claim is true, in a sample of 4040 wall clocks, what is
the probability that the mean clock life would differ from the
population mean by less than 0.40.4 years? Round your answer to
four decimal places.

A production manager at a wall clock company wants to test their
new wall clocks. The designer claims they have a mean life of 14
years with a variance of 25. If the claim is true, in a sample of
50 wall clocks, what is the probability that the mean clock life
would differ from the population mean by less than 1.5 years? Round
your answer to four decimal places.

Suppose you're given a square sheet of tinfoil with side length
9 inches. Let us make a box by removing identical squares of length
x from each corner of the sheet, and folding up the resulting
flaps. Find the dimensions of the box with the largest volume by
optimizing over x. Enter an exact value.
Height of the Box=x=

A rectangle has a length of 10 inches and a width of 6 inches. If the length is increased by x inches and the width increased
For the following exercises, use the written statements to construct a polynomial function that represents the required information.A rectangle has a length of 10 inches and a width of 6 inches. If the length is increased by x inches and the width increased by twice that amount, express the area of the rectangle as a function of x.

A wall footing is to support a 400 mm wide reinforced
concrete wall with a dead load of 270 KN/m and a live load of 210
KN/m. The bottom of the footing is 1.50 m below the final grade.
Assume the soil weighs 15.78 KN/m3 and the allowable soil pressure
is 190 Kpa. Use 75 mm as concrete cover, fc’ is 28 Mpa, fy is 415
Mpa, and concrete weights 23.5 KN/m3. Compute the:
