Answer:
Step-by-step explanation:
fractional uncertainty, to quantify the precision of a measurement for L and W is
ΔL/L = 1/4 = 0.25 = 25%
ΔW/W = 2/10 = 2/5 = 0.4 = 40%
Now the area of triangle A = L*W = 4*10 = 40m^2
The rules for propagation of error state that when two quantities are multiplied, their fractional uncertainties are added:
So,
ΔA/A = ΔL/L + ΔW/W = 0.25+0.4 = 0.65 =65%
Now we can compute uncertainty in the area, which is
ΔA = A * (ΔA/A) = 40*0.65 = 26%
Finally, we can write the area of the rectangle together with its uncertainty:
A = 40m^2 ± 26%
Answer:
Hence the number of pages read by Lonnie is 16 pages when they read a combined of 36 pages.
Step-by-step explanation:
The table that can be formed by the rate at which they study the number of pages of a book is:
Fred Lonnie total
5 4 9
10 8 18
15 12 27
20 16 36
That means when they read a combined of 36 pages.
Then the number of pages read by Fred is 20 pages.
and the number of pages read by Lonnie is 16 pages.
(
Also it could be done as :
Let Fred reads 'x' pages.
so, the number of pages read by Lonnie is: (4/5)x
Hence,
x+(4/5)x=36
on solving this linear equation we have:
x=20
and (4/5)x=16
)
Hence the number of pages read by Lonnie is 16 pages when they read a combined of 36 pages.
Answer:
the third one
Step-by-step explanation:
7 absolute is 7 absolute of any number is positive
Since you don't know 4122 - what will give you 373 you have to:
1) Add 4122 and 373 together
2) that will give you 4495
3) so 4495 is your answer
