Answer: b. False
Step-by-step explanation:
- A dummy variable is a numerical variable used in regression analysis to represent values for categorical data by using value 0 (shows absence of particular category) or 1 (shows presence of particular category) .
- We cannot use categorical data to evaluate the slope coefficient (numerical value) until we convert them into dummies.
Hence, the given statement is absolutely false.
10/6 = 6/6 + 4/6 = 1 + 4/6 = 1 + 2/3
So, the simplest mixed number equaling 10/6 is 1 2/3.
Answer: RS 49.8
Step-by-step explanation:
Given the following :
Fixed cost = RS 4430
Break even point = 89 units
Recall:
Break even point in units = Fixed cost ÷ contribution margin
Therefore,
Contribution margin equals;
(Fixed cost ÷ break even point in units)
= 4430 / 89
= 49.775280
= RS 49.8
Answer:
1512 cm³
Step-by-step explanation:
Formula
Volume of right rectangular prism = Length × Breadth × Height
As given
Two blocks of wood are shaped as right rectangular prisms.
The smaller block has a length of 9 cm, a width of 3 cm, and a height of 7 cm.
As given
The dimensions of the larger block are double the dimensions of the smaller block.
Length of the larger block = 2 × Length of the smaller block
= 2 × 9
= 18 cm
Breadth of the larger block = 2 × Breadth of the smaller block
= 2 × 3
= 6 cm
Height of the larger block = 2 × Height of the smaller block
= 2 × 7
= 14 cm
Put in the formula
Volume of larger wooden block = 18 × 6 × 14
= 1512 cm³
Therefore the volume of the wooden block is 1512 cm³ .
You would probably find it on the altitude or height.
