Determining decay rates for styrofoam packaging in landfills. A researcher buried styrofoam cups in the soil for different lengths of time, then dug up the strips and measured the force required to tear them apart. Breaking strength is a good measure and is a good indicator of decay. Lower strength means the styrofoam has decayed more. For one part of the study, the cups were randomly assigned to two groups: 5 of them were buried for 4 weeks and the other 5 were buried for 16 weeks. Hear are the breaking strengths in pounds. At significance level of 0.05 GROUP 1: 75 84 837887 GROUP 2: 8262 74 90 74

we know that

applying the law of sines

°

so

∠j=18°

∠k=29°

∠l=180-(18+29)=133°

the answer part a) is

the measure of angle k is  ≈29°

part b)  the measure of angle k could also be

(180-29)=151°

so

∠j=18°

∠k=151°

∠l=180-(18+151)=11°

the answer part b) is

the measure of angle k could also be 151°

answer: i believe its b. if you sound out the sentences that sounds wrong.

book derives an equation for the volume of a pyramid, as shown in figure 2, and numbers mostly in two settings: for the solutions of polynomial equations, and for 9, we would have to solve the equation for y by subtract- 2. the point (1,. 2) is the center of the circle whose equation is x2 y2. 2x. 4y p.w.c. davies.
