5. The total time, measured in units of 100 hours, that a teenager runs her hair dryer over a period of one year is a continuous random variable X that has the density function (r, f(0) = {2-r, 10, if 0 < x <1, if 1 <<2, elsewhere. Evaluate the mean of the random variable Y = 60X2 + 39X, where Y is equal to the number of kilowatt hours expended annually.

Time to failure of a household refrigerator. The time to failure
of a particular refrigerator type is represented by the following
pdf: , which is valid within 0 ≤ t ≤ 10 yr, and f(t) = 0 elsewhere.
a) Write the expression for R(t), integrate over t from t to
infinity (which here is 10), and obtain the cumulative Reliability
function, R(t). Then calculate the reliability for the first year,
t = 1. Round your calculated value to 2 sd...

Touchie MacFeelie publishes comic books. The only inputs he needs are old jokes and cartoonists. His production function is Q = J1/2 * L3/4
Touchie MacFeelie publishes comic books. The only inputs he needs are old jokes and cartoonists. His production function is Q = J1/2 * L3/4, where J is the number of old jokes used, L the number of hours of cartoonists’ labor used as inputs, and Q is the number of comic books produced.1) Touchie MacFeelie’s irascible business manager, Gander Mac-Grope, announces that old jokes can be purchased for $1 each and thatthe wage rate of cartoonists’ labor is $2.(a) Suppose...

1. During June 2019 Needs Business Company (NBC) runs a special offer whereby every customer who purchases a 4th of July picnic set receives a coupon for 2 dozen free gourmet hot dogs during the first week of July (presumably for use at a 4th of July picnic!). Two dozen gourmet hot dogs normally sell for $20. In a similar promotion run in October 2018 (2 free pumpkin pies during the week of Thanksgiving when a customer purchased inflatable turkey...
