240 ÷ 15 = 16
16 x 15 = 240
To lift 240 he would need to put 16, 15 lb weights on the bar
The expression can be simplified to a polynomial of degree 2.

<h3>
How to simplify the expression?</h3>
Here we have the expression:

We can directly simplify this by taking the variable as common factor:

This is a polynomial, as you can see, the maximum exponent is 2, so the degree of the polynomial is 2.

A rotation is a turn of a shape. A rotation is described by the centre of rotation, the angle of rotation, and the direction of the turn. The centre of rotation is the point that a shape rotates around. ... The direction of rotation can be described as clockwise (CW) or counterclockwise
Answer:
Sample
Step-by-step explanation:
The term that represents the description in the question is called sample.
Take for instance:
- 40 students selected from a class of 100
- 1000 people selected from a population of 100000
In the above descriptions:
40 and 1000 represent the samples while 100 and 100000 represent the populations, respectively.
Another example is when 10 cats are picked from an animal farm in order to study their eating pattern.
All these and many more represent sample.
