1. Flip a fair coin ten times. Find the probability of at least seven heads.
2. Draw five cards at once from a deck. Find the probability of getting two pairs.
3. Roll a die infinitely times. Find the probability that you see an even number before you see an one.
4. You and your friend take turns to draw from an urn containing one green marble and one hundred blue marbles, one at a time and you keep the marble. Whoever draw the green marble wins. Suppose you draw first. What is the probability that you win?

Problem 13-12 Coefficient of variation and investment decision [LO13-1]
Kyle’s Shoe Stores Inc. is considering opening an additional
suburban outlet. An aftertax expected cash flow of $120 per week is
anticipated from two stores that are being evaluated. Both stores
have positive net present values.

A furniture manufacturer produces two types of display cabinets Type A and Type B Each month x of type A and y of type B are produced. Profit on type A is 300SR and profit on type B is 150SR. The following constraints control monthly production :
(i) Not more than 50 display cabinets of type A and 40 display cabinets of type B can be made
(ii) To show a profit at least 60 display cabinets in all must be made.
(iii) The maximum number of display cabinets that can be produced is 80.
How many display cabinets of type A must be produced per month to maximize the profit:

Two factories located in different cities, owned by the same organization (ABC Corp), produce the identical product. The product they make is a specialized all-terrain vehicle. In 2002, based on productivity data from a random sample of workers, management felt the average labor productivity of the two plants could be improved. So, both plants underwent identical process improvements through 2003. In 2004, the worker productivity was gauged for both plants using the same set of workers.

Factory A Before = worker productivity for Factory A measured in units finished per day measured in 2002 i.e. before improvement intervention
Factory B Before = worker productivity for Factory B measured in units finished per day measured in 2002 i.e. before improvement intervention
Factory A After = worker productivity for Factory A measured in units finished per day measured in 2004 i.e. after improvement intervention
Factory B After = worker productivity for Factory B measured in units finished per day measured in 2004 i.e. after improvement intervention
You are the consultant and the management wants the following questions answered.
Assume α-level of 10%. You have to use p value method. Assume equal variances wherever needed.

A 1200-kg car moving at 25 m/s suddenly collides with a stationary car of mass 1,002 If the two vehicles lock together, what energy was lost to heat?
In: Physics
please answer both
1)The energy produced by a 83 W bulb is harnessed and used to lift a 32.5 kg weight. If there are no frictional losses and the bulb runs for 1,633 seconds, how high will the weight rise, in m?
2)A ball of mass 1.56 kg is released from rest at height 7.13 mabove the floor. It falls, hits the ground, and rebounds to height 4.12 m above the floor. Assume none of the losses are due to air friction. Find the work done against friction, in J, on the ball during the contact with the ground.
HINT: This is a positive number!

a) The rent he pays on his greenhouse in the short run
b) The rent he pays on his greenhouse in the long run
c) the cost of soil, water, and seeds in the short run
d) the per-unit cost of producing a nursery plant in the short run
e) the opportunity cost of shutting the nursery down and not producing any plants in the short run

The length of nylon rope from which a mountain climber is
suspended has a force constant of 1.40 104
N/m. (Hz)
(a) What is the frequency at which he bounces, given his mass plus
equipment to be 70.0 kg? (m)
(b) How much would this rope stretch to break the climber's fall,
if he free-falls 2.00 m before the rope runs out of slack?
(c) Repeat both parts of this problem in the situation where twice
this length of nylon rope is used. Bounce frequency and distance
stretched.
