A 12-inch bar that is clamped at both ends is to be subjected to an increasing amount of stress until it snaps. Let Y = the distance from the left end at which the break occurs. Suppose Y had pdf: ff(yy) = � � 1 24� yy �1 − yy 12� , 0 ≤ yy ≤ 12 0, h Compute the following: a. The cdf of Y b. P(Y ≤ 4), P(Y > 6) and P(4 ≤ Y ≤ 6). c. E(Y), E(Y2 ), and Var(Y) d. The probability that the break point occurs more than 2 in. from the expected break point. e. The expected length of the shorter segment when the break occurs.

sorry, i don't know i just need points, i'm new here. chao

child does not get an education so she can use the molla on junk

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
