Answer:
a) There is outlier (lower category), but this outlier seem certain to be due to an error.
b) There is outlier (upper category), this outlier seem certain to be conceivably correct.
Step-by-step explanation:
a) The outlier in the rock weight is certain to be due to an error. As shown, the rock was weighed five time to ascertain the actual weight or perhaps to known the mean weight. <em>Thus, having a value 4.91 can not be true. It can only be due to an error of recording the values.</em> It suppose to be recorded as 49.1.
b) Since this was a sample of annual income of five different families, it quite possible that a particular family annual income is $1, 200, 000. Hence, we cannot regard this outlier an error, rather conceivably true.

Answer:
True
Step-by-step explanation:
It depends on two factors :mass of the objects and distance between the objects

<h3>
Explanation:</h3>
Unlike fractions: ones with different denominators.
Like fractions: ones with the same denominator.
__
Examples:
1/3 and 1/4 are unlike fractions, because their denominators are different.
1/3 and 1/6 are also unlike fractions, because their denominators are different.
2/13 and 17/13 are like fractions, because their denominators are the same.

<em>Comment on like/unlike fractions</em>
In general, addition and subtraction must be carried out on <em>like</em> fractions. That is, for unlike fractions to be added or subtracted, they must first be converted to like fractions. This is done by expressing both fractions using a common denominator. The common denominator is often chosen as the Least Common Multiple (LCM) of the two denominators, but it can be simply the product of the denominators:
a/b + c/d = (ad)/(bd) +(bc)/(bd) = (ad +bc)/(bd)
The reason for using the LCM of the denominators is that it <em>may</em> save work in reducing the final sum to lowest terms.
Answer:
.B.An orthocenter can be outside of its triangle
Step-by-step explanation:
The orthocenter of a triangle is the intersection of the point drawn perpendicular from the vertices of the triangle. While normal equilateral triangles for instance have their point of intersection drawn inside the triangle, the orthocenter of a triangle of an obtuse triangle is outside of the triangle. A right angled triangle has its orthocenter drawn at the vertex of the right angle and really inside the right angled triangle.
Hi there!
To find equivalent fractions, we need to multiply both the numerator and the denominator by the same number.
These equivalent fractions are the original fractions multiplied by 2/2:
2/3 = 4/6
1/2 = 2/4
5/12 = 10/24
Hope this helps!
