Answer:
144
Step-by-step explanation:
Put the number where the variable is and do the arithmetic.
9p^2 = 9·4^2 = 9·16
9p^2 = 144 . . . . when p=4
52.35 ft^2
1/2times 9.2 times 11.9 times sin(27)
A measure of the variation around the estimate of the mean.
The standard deviation is a statistic that lets you know how tightly all the subjects are clustered around the mean in a set of data. A single standard deviation away from the mean in either of the directions accounts for somewhere around 68 % of data. If two standard deviations are away from the mean, it accounts for around 95% of data. If three standard deviations are away it accounts for 99% of the data.
1) The total range of variation in the dataset is called RANGE.
3) A measure of the variation around the estimate of the mean is SEM (STANDARD ERROR OF THE MEAN).
4) The most common value observed (highest frequency) is MODE.
The Answer To That Question Would Be : The Actual Distance Is 70 miles
Answer:
The ratios of their perimeters is 3/4
Step-by-step explanation:
In this question, we are asked to find the ratio of two perimeter of different regular polygons having the same number of sides but different side lengths.
A regular polygon is a polygon that has its all its sides to be of equal lengths. Now to find the perimeter of this kind of polygon, what we need to do is to multiply the number of sides that we have by the length of one of the sides.
Now, since we know that the number of sides of the polygons are equal, we can say that both polygons each have a total length of n sides each.
For the 6 inch side polygon, the perimeter of the polygon would be 6 * n = 6n inches
For the 8 inch side polygon, the perimeter of the polygon would be 8 * n = 8n inches
The ratio of the two thus becomes;
6n : 8n
This is same as writing 6n/8n
This is equal to 3:4 to the lowest ratio( we first divide by n on both sides, then 2 after wards to arrive at this answer.
