Answer:
The two expression to represent area is (5 x - 10) sq. units or 5( x- 2) sq. units
Step-by-step explanation:
Here, the length of the rectangle = (x-2) units
The width of the rectangle = 5 units
Now, AREA OF A RECTANGLE = LENGTH x WIDTH
So, here AREA = 5 ( x- 2)
= (5 x - 10) sq. units
( as by Distributive property: A (B-C) = AB - AC)
Hence, the two expression to represent area is (5 x - 10) sq. units or 5( x- 2) sq. units
Answer:
x = 14
Step-by-step explanation:
because 4×8 is 32
if x = 14
14 - 10 = 4
14 - 6 = 8
8 x 4 = 32
Answer:
Whichever reasoning processes and research methods were used, the final conclusion is critical, determining success or failure. If an otherwise excellent experiment is summarized by a weak conclusion, the results will not be taken seriously.
Success or failure is not a measure of whether a hypothesis is accepted or refuted, because both results still advance scientific knowledge.
Failure lies in poor experimental design, or flaws in the reasoning processes, which invalidate the results. As long as the research process is robust and well designed, then the findings are sound, and the process of drawing conclusions begins.Whichever reasoning processes and research methods were used, the final conclusion is critical, determining success or failure.

Answer:
Step-by-step explanation:
number of cards = 52
number of queen = 4
number of spades = 13
A) probability that the tenth card is a queen
drawn time (r) = 1
position of success(x) = 10th
p = 4/52
P( x,r,p) = 
p(10,1,4/52) = 9C0(4/52)^1 * (48/52)^9 = 0.0374
B) probability the twentieth card is a spade
x = 20
r = 1
p = 13 / 52
P(20,1,26/52) = 19C0(26/52)^1 * (26/52)^19 = 0.0010
c) The last five cards been spades
p(last five cards been spades )
p(48..52, 5, 13/52 ) = 47...52C4(13/52)^5 * (39/52)^48..52 - 5
