Answer:
On the average, estimates will be either be 0.2 meters too short or too long.
Step-by-step explanation:
Standard deviation is normally used to show how the actual value of a variable in a given sample deviates from the mean or average value of the sample. The deviation could be slightly more or less than the average value by the value of the standard deviation. Therefore, in this question, the standard deviation shows that the estimates could be 0.2 m short or more than the mean.
Answer:
3.6, 3.60
Step-by-step explanation:
Equivalent decimal numbers may have different numbers of trailing zeros.
_____
<em>Comments on equivalents</em>
The number can be written in several different forms, including ...
and variations on these.
As a straight standard-form decimal number this representation (3.600) indicates it has 4 significant figures. <em>There is no other equivalent standard-form decimal number that will convey the same information regarding significant figures</em>. The form in scientific notation above will convey that information because it retains the two trailing zeros.
The mixed numbers can be considered to have a precision matching that of the fraction, but when we're concerned about the precision of the answer, we usually use a decimal or scientific notation presentation.
The formula is 180(n-2)= 1140 then you divide 1140 by 180 to get 8 so then it would like like n-2=8 add the 2 over and n (being the number of sides)= 10 so your answer will be 10
Answer:
yup
Step-by-step explanation:
If there are 40 children aged twelve and under and x of them are under three years old, 40 - x aged three twelve years old. From the 92 people that where taken by the company on whale watching trips, 52 are over twelve years old. The equation that best show the total cost, C is
(40 - x)(36) + (52)(48) = C
Rearranging the equation gives,
x = 40 - ((C - 2496)/ 36)
