For a variety of reasons, market participants did not accurately measure the risk inherent with financial innovation such as MBS and CDOs or understand its impact on the overall stability of the financial system. For example, the pricing model for CDOs clearly did not reflect the level of risk they introduced into the system. Banks estimated that $450bn of CDO were sold between "late 2005 to the middle of 2007"; among the $102bn of those that had been liquidated, JPMorgan estimated that the average recovery rate for "high quality" CDOs was approximately 32 cents on the dollar, while the recovery rate for mezzanine CDO was approximately five cents for every dollar.
How much did JPMorgan estimate was the average recovery rate for mezzanine CDOs that had been liquidated?
A: approximately five cents for every dollar

Assistive listening devices in many theaters and similar spaces use arrays of infrared LEDs to send sound to listeners' receivers. Light-emitting diodes (as well as semiconductor lasers) are used to send data over many types of fiber optic cable, from digital audio over TOSLINK cables to the very high bandwidth fiber links that form the Internet backbone. For some time, computers were commonly equipped with IrDA interfaces, which allowed them to send and receive data to nearby machines via infrared.
LEDs can send data over what type of cable?
A: fiber optic

Another theory describes its derivation from a non-Slavic warrior class,:42, 6466 forming a distinct element known as the Lechici/Lekhi (Lechitow):430 :482 within the ancient Polonic tribal groupings (Indo-European caste systems). This hypothesis states this upper class was not of Slavonic extraction:482 and was of a different origin than the Slavonic peasants (kmiecie; Latin: cmethones):430 :118 over which they ruled.:482 The Szlachta were differentiated from the rural population. The nobleman's sense of distinction led to practices that in later periods would be characterized as racism.:233 The Szlachta were noble in the Aryan sense -- "noble" in contrast to the people over whom they ruled after coming into contact with them.:482 The szlachta traced their descent from Lech/Lekh, who probably founded the Polish kingdom in about the fifth century.:482 Lechia was the name of Poland in antiquity, and the szlachta's own name for themselves was Lechici/Lekhi.:482 An exact counterpart of Szlachta society was the Meerassee system of tenure of southern Indiaan aristocracy of equalitysettled as conquerors among a separate race.:484 The Polish state paralleled the Roman Empire in that full rights of citizenship were limited to the szlachta. The szlachta were a caste, a military caste, as in Hindu society.
WHat was the name of the distinct element from a nnon-Slavic warrior class?

In Charleston, the African American population increased as freedmen moved from rural areas to the major city: from 17,000 in 1860 to over 27,000 in 1880. Historian Eric Foner noted that blacks were glad to be relieved of the many regulations of slavery and to operate outside of white surveillance. Among other changes, most blacks quickly left the Southern Baptist Church, setting up their own black Baptist congregations or joining new African Methodist Episcopal Church and AME Zion churches, both independent black denominations first established in the North. Freedmen "acquired dogs, guns, and liquor (all barred to them under slavery), and refused to yield the sidewalks to whites".
Black left which religious denomination is great numbers after slavery?
A:
Southern Baptist Church
