If the data from two geiger counters are combined, how will the standard deviation of the new data set compare to that of each of the indivdual geiger counters?

Step-by-step explanation:

Standard deviation is the measure of variation of a set of value. The standard deviation increases as the variation of the data increases.

For a two similar data values of Geiger counters, if new data set were compared to that of each of the individual Geiger counters then the standard deviation would decrease as the effect of increasing sample size. But in a situation where the Geiger counter data values are well distributed with varying data values and well distributed range in value, the standard deviation would increase.

step-by-step explanation:

the areas of two similar triangles are 18 cm2 and 8 cm2. one of the sides of the first triangle is 4.5 cm. what is the length of the corresponding side of the other triangle?
