A garden hose attached with a nozzle is used to fill a 7-gal bucket. The inner diameter of the hose is 1”, and it reduces to ½” at the nozzle exit. If it takes 32 s to fill the bucket with water, determine the average velocity of water at the nozzle exit
A moving airplane dropped a cargo (ignore the effect of air resistance). If the plane from which the cargo was dropped was flying at a height of 600 m, and the cargo lands 300 m horizontally from the initial dropping point,
a. how fast was the plane flying when the cargo was released? (Vix=?)
b. what was the velocity of the cargo right before it hit the ground? (Vfy=?)
Solve for time first using this equation: t= √ 2y/ay
c. Draw a figure or diagram that illustrates the given problem.

Can Nonsense mutation be reversed by hydroxylamine? Why or why not?
Whatever the solvent used, the solution should be topped-up to its final volume using water. True or False?
What mutations are produced by ionizing and UV Radiation?
In a survey of 200 students, 78 of the 120 females in the sample passed math 17 on their first take while this figure is 60 among the males. Will you agree that the proportion of males who passed math 17 on their first take is higher than the proportion of females who passed math 17 on their first take?test at a 0.05
A population consists of five numbers 1, 2, 3, 4, 5 and 6. Suppose samples of size 2 are drawn from this
population.
(a) Find the mean and variance of the population
(b) Describe the sampling distribution of the sample means.
(c) Find the mean and variance of the sampling distribution of the sample means.
If marginal revenue is greater than average revenue, average revenue increases.
1. True
2. False
The basic reason for the rising part of the short-run marginal cost curve is the declining part of the marginal product curve which, in turn, is the result of the law of diminishing returns..
1. True
2. False
