Answer:
252 cm²
Step-by-step explanation:
Area of a rectangle is width times length:
A = WL
If the width and length increase by a factor of 1.5:
A = (1.5 W) (1.5 L)
A = 2.25 WL
So the area increases by a factor of 2.25.
2.25 × 112 cm² = 252 cm²
Answer:
16
Step-by-step explanation:
Subtracting the given expressions, that is
3b² - 8 - (b(b² + b - 7) ) ← simplify parenthesis
= 3b² - 8 - (b³ + b² - 7b) ← distribute parenthesis by - 1
= 3b² - 8 - b³ - b² + 7b ← collect like terms
= - b³ + 2b² + 7b - 8 ← substitute b = - 3
= - (- 3)³ + 2(- 3)² + 7(- 3) - 8
= - (- 27) + 2(9) - 21 - 8
= 27 + 18 - 21 - 8
= 16
Answer / Step-by-step explanation:
To properly understand the principle behind the solving of this question, it would be necessary to define and go through some basic terms and their definition.
Therefore to start with, a completely randomized single factor is a type of experiment in which One factor of two or more levels has been manipulated. e.g, the experiment may be investigating the effect of different levels of cost, expenditure or different advertisements
Also, it should be noted that in the area of groping of the experiment, At this point, Each group of different level receives one of the a levels of the independent variable with participants being treated identically in every other respect. The two-group experiment considered previously is a special case of this type of design.
Consequentially, the answer to the narrative of the question would then be:
N= 3 factors levels x 5 replicates = 15
Degrees of freedom for the factor: a – 1 = 3 – 1 = 2
Degrees of freedom Total = 15 – 1= 14
Degrees of freedom error = Total – factor = 14 – 2 = 12
Bounds of P-value for F = 2.91 with 2 and 12 degrees of freedom are
= 0.01 < P < 0.05
