Calculations:
1. Suppose a large rock is ejected from a volcano with a speed of 25m/s and at an angle of 35*
the horizontal. If the rock strikes the side of the volcano at an altitude 20m lower than the star
point.
(a) Calculate the time it takes the rock to reach the starting point.
(b) What are the magnitude and direction of the rock's velocity at impact?
Who invented stroma-free hemoglobin? When was it invented?
Two rods of equal length (0.45 cm) and diameter (1.5 cm) are placed end to end. One rod is aluminum, the other is brass. If a compressive force of 8400 N is applied to the rods, how much does their combined length decrease?
Find the area under the normal curve in each of the following cases. between z = 0 and z = 1.63 between z= 0 and z = 1.78 between z = -2.46 and z = 1.55 to the right of z = 2.35 to right of z = -1.31 to the left of z = 0.35 to the left of z - 1.85 to the right of z = -0.95
If 1.6 accidents can be expected an intersection on any given day, what is the
probability that there will be 3 accidents on any given day?
The annual wages X of the staffs of collage of natural sciences are normally
distributed with mean µ and standard deviation σ. Knowing that P(X > 42320) =
0.0853 and P(X < 41230) = 0.6103, find µ and σ.
What is the difference in mean fat stores between moose with wolves present and moose with wolves absent (x̄p - x̄a)?
Suppose that an examination consists of six true and false questions, and assume that
a student has no knowledge of the subject matter. The probability that the student will
guess the correct answer to the first question is 30%. Likewise, the probability of
guessing each of the remaining questions correctly is also 30%.
a. What is the probability of getting more than three correct answers?
b. What is the probability of getting at least two correct answers?
c. What is the probability of getting at most three correct answers?
d. What is the probability of getting less than five correct answers
A ball is drawn at random from an urn containing one red and one white ball. If the
white ball is drawn, it is put back into the urn. If the red ball is drawn, it is returned to
the urn together with two more red balls. Then a second draw is made. What is the
probability a red ball was drawn on both the first and the second draws?
