Well, what I’d do is just see who has the most which is Bill and then for the other question I’d just subtract 7.8 - 7.2 which is equal 6 so the pH is greater by .6

How quickly do synthetic fabrics such as polyester decay in landfills? A researcher buried polyester strips in thes oil for diff
ad-work [718]

Answer:

no enough evidence to draw up a conclusion

Step-by-step explanation:

Data:

let: \mu _{1} = decay after 2 weeks

    \mu _{2} = decay after 16 weeks

Making the hypotheses:

Null hypothesis; H_{o} = \mu _{1}  - \mu _{2} = 0

the deviation = 0.05

the standard difference  = 4

Conditions:

The normal distribution curve can be plotted on a graph and the plot shows that the distribution is a skewed distribution.

Then,

t = \frac{(123.8-16.4)-0}{\sqrt{\frac{4.6^{2} }{5}+\frac{16.09^{2} }{5}   } } \\  = 0.989

Therefore, it can be concluded that 0.1983 > 0.05. This presents our failure to reject the null hypothesis.

Thus, there is not enough evidence to conclude that polyester decays more in less than 2 weeks.

I NEED ASAP DUE IN 20 MINS
11111nata11111 [884]

Answer:

y = 45 / 2x + 50

Step-by-step explanation:

The best equation for the line of the best fit would be y = 45 / 2x + 50.

The slope would be 45 / 2 and the y-intercept would be ( 0 , 50 ).

I used the points, ( 0 , 50 ) and ( 4 , 140 ) to get the equation, slope, and the y-intercept.

I used those points because they were the most accurate ones that I know for now.

Also, remember the formula is, "y = mx + b."
