Pinky bauer, chief financial officer of harrison haulers, inc., suspects irregularities in the payroll system. she knows that 2,500 payroll vouchers have been issued since january 1, 2000, and her staff doesn't have time to inspect each voucher. so, she randomly selects 53 as a starting point and orders her staff to inspect the 53rd voucher and each voucher at an increment of 100 (53, 153, 253, her sample is a a. stratified sample b. simple random sample c. convenience sample d. systematic sample

Your answer choice will be C. because the company is conveniently choosing every 53rd voucher without any real strategy to it.

large crystals result from very slow cooling.

evaporation of water: this would produce an evaporite which is a sedimentary rock. like a salt pan in a desert. not possible to have volcanic rocks originate this way.

crystalization in molten earth: slow cooling over time. (hundreds to millions of years)

crystalization at earth's surface: this results in fast cooling. (a few hours to a few months or years)

crystalization from cooling off hot water: that would be a hydrothermal deposit. while associated with volcanics they are not volcanic rocks themselves and usually occur fairly rapidly.

hello, it is c -4
