Answer:
12
Step-by-step explanation:
To determine the number of discs, divide the area of the metal sheet by the area of the discs
The metal sheets are in the shape of a rectangle, thus the area of a rectangle would be used to determine the area of the sheet
Area of a rectangle = length x breadth
56 x 33 = 1848 cm^2
The disc is in the shape of a circle.
area of a circle = πr²
π = 3.14
r = radius
3.14 x 7² = 153.86 cm²
Number of discs = 1848 /153.86 = 12
You just multiply each of the coordinates by the scale factor. No extra work since it’s from the origin.
Doing this gives:
J’ (2.5 , 10)
K’ (15 , 10)
L’ (15 , 2.5)
M’ (2.5 , 2.5)
The answer is 3

Answer:
The answer is below
Step-by-step explanation:
Let Y represent the profit per day, and x represent the number of bar sold per day. Hence:
Y = 0.25x - 2
a) The mean is given as:
b) The standard deviation of y is:
(9 * 2) + 1 = 18 + 1 = 19/2 is it's fractional notation/mixed number.
