Answer:
Width = (3x^2) [m]
Length = (4x^2 + 2x + 5) [m]
Step-by-step explanation:
Area of the rectangle
Area = width * length
Area = 12x^4+6x^3+15x^2 [m^2]
The width of the rectangle (in meters) is equal to the greatest common monomial factor of the area.
If we factor the equation, we get
12x^4+6x^3+15x^2 = (3x^2)*(4x^2 + 2x + 5)
This means that,
Width = (3x^2) [m]
Length = (4x^2 + 2x + 5) [m]
<span>Understand that:
• the sum of two positive numbers is greater than either
number.
Understand that addition is the inverse of subtraction (addition
reverses subtraction and vice versa) and use this to check
results.
Respond rapidly to oral or written questions, explaining the
strategy used. For example:
• 654 add 50… Add 68 to 74…
• 7 add 12 add 9… Add 15, 6, 4, 15 and 1…
• What is the sum/total of 26 and 39? And of 13, 62 and 3?
• How many altogether are 121 and 35? And 61, 37 and 6?
• Increase 48 by 22.
• Which three numbers could have a total of 103?
Are there any others?</span>
Answer:
Step-by-step explanation:
a. Systematic sampling
Reason-Every individual will be in the sample. The is referred to as the sampling interval.
-The sampling interval has a random start point but with a fixed, periodic interval.
-This method was appropriate given the homogeneous nature of the population.
-It is also representative given it has no bias.
b. A sample frame is the part of a population from which information is drawn.# In our sample, the sample frame is person.
#No parts c, d as implied in the question
