<span>The median is a better measure of center when there is an outlier which will make the mean not be a good estimate of the center. Option B has $1075 as an outlier (i.e. it is far away from the other data sets). Hence, the median will be a better estimate of the center. Similarly, 94 is an outlier in option C and hence, the median is a better estimate. Options A and D has no outliers, making the mean a good estimate of the centre.</span>
<span>Describe a situation where it is easier to use decimals than fractions and explain why:
</span>When you must multiply numbers that are NOT whole, decimals are easier to change in the sense that setting up a multiplication problem with decimals rather than fractions is much simpler and easier to calculate.
Let's go through the answer choices one by one:
A. False. The line segment contains more than just the endpoints
B. False. There are points in this description that extend beyond the endpoints. If this was a line instead of a segment, then choice B would be the answer
C. True. This is the answer. Though your teacher should have added "collinear" to the sentence to make it clear that the points are between M and N, and also collinear to M and N. All of these points form the line segment MN
D. False. That would be the perpendicular bisector of MN

So once again, the final answer is choice C
Answer:
Irrational Number: A number that cannot be written as a fraction
a
b
(where b ≠ 0), a repeating decimal, or a terminating decimal.
Rational Number: A number that can be written as a fraction
a
b
(where b ≠ 0), a repeating decimal, or a terminating decimal.
Repeating Decimal: A decimal where, when dividing, a digit or group of digits repeats without end in the quotient; there is a pattern in the digits that repeat without end.
Terminating Decimal: A decimal that, when dividing, ends with a remainder of zero.
Perfect cube: A number that is made by cubing a number: a3 = a • a • a.
Perfect square: A number that is made by squaring a number: a2 = a • a.
Cube Root:
if a3 = b, then a = 3√b
For principal square root this was the best I could do: The principle of square roots requires that the square root of the side with the unknown (x) only includes x without any exponent (other than 1). The simplest form that fits this criterion is: but x can also be an expression.
I hope this helps :3
All in all there are 26 pieces of clothing available. The probability of randomly selecting a blue piece is equal to 18/26. Also, the probability of picking up a pants is 14/26. There are 10 blue pants and the probability of picking up one of those is 10/26. The answer can be computed as follows:
P(A or B) = (18/26) + (14/26) - (10/26) = 22/26
P(A or B) = 22/26 or 11/13
