Answer:
It has 8 significant figures
Step-by-step explanation:
Product of 11,435 meters and 19.35 meters
Product means multiplication(×)
= 11,435 × 19.35
= 221,267.25
Product of 11,435 meters and 19.35 meters = 221,267.25
It has 8 significant figures
Significant figures are non-zero digits or trapped zeros
Using their concepts concept, we have that:
a) The mean of the data-set is of 81.6.
b) The median of the data-set is of 80.
<h3>What is the mean?</h3>
The mean of a data-set is given by the <u>sum of all observations in the data-set divided by the number of observations</u>.
In this problem, there are 2 + 8 + 6 + 3 + 9 = 28 observations, hence the mean is:
M = (70 x 2 + 75 x 8 + 80 x 6 + 85 x 3 + 90 x 9)/28 = 81.6.
<h3>What is the median?</h3>
The median of a data-set is the 50th percentile, the value that separates the median in two halfs.
This data-set has an even number of elements, hence the median is the mean of the 14th and 15th elements, as 28/2 = 14. Both elements are 80, hence the median is of 80.
