Order of Operations in Mathematics follow this following rule :
This rule is known as the PEMDAS method.
In working on a mathematical problem, we first calculate operation that is in parentheses, follow by exponentiation, then multiplication or division, and finally addition or subtraction.
Let us tackle the problem!
1 fifth of 12
15 times as much as 1 fifth of 12
Let's solve the above operations!
15 times as much as 1 fifth of 12 → 15 × ( ¹/₅ × 12 ) = 36

Answer:
inches
Step-by-step explanation:
Let initial length of the plant was "x" inches.
Plant grew inches or inches per month.
So after one month height of the plant = inches
Height of the plant after one month = or inches
So expression will be
=
We further solve it x = -
=
=
or x = inches
therefore, initial of the plant was inches height.
The number would be greater then 36.
An inequality is a relation which makes a non-equal comparison between two numbers or mathematical expressions.
here, we have,
Let x represent the unknown number. The opposite of this number would be represented by -x.
1/3 of this is found by multiplying by 1/3; this gives us
1/3×(-x)
Since it is less than 12, this gives us
1/3×(-x) < 12
To cancel the 1/3, we can multiply both sides by 3:
1/3×(-x)×(3) < 12×(3)
-x < 36
We can cancel the negative by dividing both sides by -1. When we multiply or divide an inequality by a negative number we flip the inequality:
-x/-1 < 36/-1
x > 36
Our number must be greater than 36.

Answer:
The number would be greater then 36.
Step-by-step explanation:
Let x represent the unknown number. The opposite of this number would be represented by -x.
1/3 of this is found by multiplying by 1/3; this gives us
1/3(-x)
Since it is less than 12, this gives us
1/3(-x) < 12
To cancel the 1/3, we can multiply both sides by 3:
1/3(-x)(3) < 12(3)
-x < 36
We can cancel the negative by dividing both sides by -1. When we multiply or divide an inequality by a negative number we flip the inequality:
-x/-1 < 36/-1
x > 36
Our number must be greater than 36.
is the polynomial obtained after dividing $p(x)$ by $(ax+b)$

Which statement about Linda's experiment is true?
A. The outcomes do not appear to be equally likely, so a uniform probability model is not a good model to represent probabilities in Linda's experiment.
B. The outcomes appear to be equally likely, so a uniform probability model IS a good model to represent probabilities in Linda's experiment.
C. The outcomes do not appear to be equally likely, so a uniform probability model is a good model to represent probabilities in Linda's experiment.
D. The outcomes appear to be equally likely, so a uniform probability model is not a good model to represent probabilities in Linda's experiment.
Option: B is the correct answer.
B. The outcomes appear to be equally likely, so a uniform probability model IS a good model to represent probabilities in Linda's experiment.
Equally likely outcomes--
The equally likely outcomes are the one that have equal chance or probability or likelihood of occurring.
Also, from the given relative frequency from the table we could observe that the outcomes have approximately the same relative frequency or the chances of their occurrence is almost similar.
Hence, the outcomes are equally likely.
Also a uniform probability model is one in which the outcomes have equal probability.
Hence, the statement that is true about Linda's experiment is:
Option: B
