Probability of 1st/2nd/10th sample = 1/10

Step-by-step explanation:

All the possible combinations of the 3 size samples from a 5 size population have been listed without repetition.

Total Numbers of Samples = 10

To find the probability of finding the first sample from random sampling procedure,

Probability = Number of desired outcomes/ Total number of outcomes

Where Number of desired outcome is 1 and total number of outcomes is 10.

Probability = 1/10

Similarly, to find 2nd sample or 10th sample, the number of desired outcomes is same i.e 1, hecne the probability remains the same i.e 1/10

Surface roughness can be measured as either an arithmetic average (AA) or a root-mean-square (RMS) average. Which value is almos

Nat2105 [25]

Answer:

Root-mean-square (RMS)

Step-by-step explanation:

Arithmetic average is the average of all the values of the surface peaks and valleys.

$AA=\frac{\sum^n_{i=1}|y_i|}{n}$

Root mean square is the root of the sum of the squares of each of the values of the surface peaks and valleys divided by the number of values

$RMS=\sqrt{\frac{\sum^n_{i=1}{y_i}^2}{n}}$

where n = the number of values

So, the root-mean-square RMS is always greater than the arithmetic average (AA).

The population of geckos in a reptile habitat can be represented by the expression s(1.35)t, where s is the initial number of ge

vovangra [49]

The formular for an exponential population growth is given by

$P(t) = P_0(1 + r)^t$

where: r is the rate per period, t is the time and $P_0$ is the initial population.

Comparing the above formular with the given formula we have

$s(1.35)^t=s(1+0.35)^t \\ \\ r=0.35\ or\ 35%$

Therefore, the <span>equivalent quarterly growth rate of the geckos is 8.75%.</span>
