One minute after it is released, a hot-air balloon rises 120 feet. In each succeeding minute, the balloon rises only 60% as far
MArishka [77]

Answer:

25.92 feet

Step-by-step explanation:

In the first minute, the hot air balloon rises 120 feet.

And it is given that, the balloon rises in a minute only 60% of the height it rose in the previous minute.  

Therefore, in the second minute, the balloon rises by (120×0.6) =72 feet

And in the third minute, the balloon rises by (72×0.6) =43.2 feet

Hence, in the fourth minute, the balloon rises by (43.2 ×0.6) =25.92 feet (Answer)

Many people feel that the drying of pavement marking paint is much too slow. You spend several days looking for the fastest dryi
slavikrds [6]

Answer:

21

Step-by-step explanation:

Using<em> Simple Random Sampling</em>, we can estimate the sample size by the formula

\bf n=\frac{Z^2S^2}{e^2}

where  

n = sample size

Z = the z-score corresponding to the confidence level 99.5%

S = the assumed standard deviation = 3 seconds

e = margin of error = 2 seconds

<em>It is worth noticing that the higher the confidence level, the larger the sample should be. </em>

The z-score corresponding to a confidence level of 99.5% can be obtained either with a table or the computer and equals

Z = 3.023

Replacing the values in our formula

\bf n=\frac{(3.023)^23^2}{2^2}=20.5616\approx 21

So the size of the sample should be at least 21.
