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

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

here is a big fat

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130
