Draw conclusions Regression Analysis - ANSWER-In statistical modeling, regression analysis is a set of statistical processes for estimating the relationships between a dependent variable and one or more independent variables. Sedimentary Rocks - ANSWER-Sedimentary rocks are types of rock that are formed by the accumulation or deposition of small particles and subsequent cementation of mineral or organic particles on the floor of oceans or other bodies of water at the Earth's surface - Erosion and weathering include the effects of wind and rain, which slowly break down large rocks into sediments, such as sand or mud. Precipitation and lithification are processes that build new rocks or minerals. - Precipitation is the formation of rocks and minerals from chemicals that precipitate from water. For example, as a lake dries up over many thousands of years, it leaves behind mineral deposits. - Lithification is the process by which clay, sand, and other sediments on the bottom of the ocean or other bodies of water are slowly compacted into rocks from the weight of overlying sediments.
