Agroup of asu sustainability student took 100 soil samples in different places in the valley. they test those samples for a certain chemical. the test is not 100% correct. if the soil contains the chemical, the test shows a positive test result 90% of the time. if the soil does not contain the chemical, it gives a negative result 80% of the time. if 20 of the soil samples contain chemicals, what is the probability the sample contains a chemical if you have a positive test return for the sample?

The formula for the lateral area of a right cone is la = rs, where r is the radius of the base and s is the slant height of the cone. which are equivalent equations?

Data for the height of a model rocket launch in the air over time are shown in the table. darryl predicted that the height of the rocket at 8 seconds would be about 93 meters. did darryl make a good prediction? yes, the data are best modeled by a quadratic function. the value of the function at 8 seconds is about 93 meters. yes, the data are best modeled by a linear function. the first differences are constant, so about 93 meters at 8 seconds is reasonable. no, the data are exponential. a better prediction is 150 meters. no, the data are best modeled by a cubic function. a better prediction is 100 meters.
