5. A cereal factory’s machine is adjusted to fill boxes with a mean of 12 ounces and a standard deviation of 0.6 ounces. Assume the amount of fill is normally distributed. a. In order to ensure boxes are not inappropriately filled, they need to be between the 45 and 55 percentiles. How many ounces should be in each box to...

An Insulated tube is filled with a large number n of lead spheres, each of mass m. The tube is inverted s times so that the spheres completely fall through an average distance L each time. The temperature of the spheres is measured before and after the inversions and the resultant change in temperature of delta T What is the...

Question 8 (1 point) Historically, the average score of PGA golfers for one round is 73.9 with a standard deviation of 1.1. A random sample of 99 golfers is taken. What is the probability that the sample mean is between 73.9 and 74.03? 1) 1.3802 2) 0.3802 3) -1.8011 4) The sample mean will never fall in this range 5)00470

A rock thrown with speed 6.00 m/s and launch angle 30.0 ∘ (above the horizontal) travels a horizontal distance of d = 16.5 m before hitting the ground. From what height was the rock thrown? Use the value g = 9.800 m/s2 for the free-fall acceleration. Find the height yi from which the rock was launched.

The Si- ion is stable with respect to the neutral atom and an electron. This is evident in the value of the electron affinity of silicon which is 133.6 kJ mol-1. What is the longest wavelength of light that could remove an electron from a Si- ion? In which region of the electromagnetic spectrum does this light fall? Wavelength =...
