Answer:
4'9"
Method 1:
First, convert both numbers into inches. Remember that 1' = 12", and the rest is like a remainder.
7'5" = (7*12)+5 = 84+5 = 89
2'8" = (2*12)+8 = 24+8 = 32
Next, subtract the two numbers.
89 - 32 = ?
89 - 32 = 57
There's your answer! You can change it back into feet by dividing it by 12.
57 / 12 = 4.75 = 4'9"
Method 2:
Another way of solving this problem is to borrow from the "feet" place.
7'5" - 2'8"
You can't take 8 away from 5, so you borrow from the "feet" place. Remember that unlike normal borrowing, you need to add 12 instead of adding 10.
6'17" - 2'8" = 4'9"
Whichever method you choose, you should get the same answer!
The required volume of the prism is 48 cubic centimeters
<h3>Volume of a prism. </h3>
The formula for calculating the volume of a prism is expressed as:
V = lwh
where l is the side length
w is the width
h is the height
Given the following
l = 2 cm.
Height 2cm
Width 12 cm
Substitute
V = 2(2)(12)
V = 48 cubic centimeters
Hence the required volume of the prism is 48 cubic centimeters

#SPJ1
Given 10 independent part,
No mean shift
This implies that,
The mean is 10
It also means that the variance is 0
And also the standard deviation is 0.
Then, the sigma deviation is
3×0+10=10.
Since none of the data is at such a high point, the manufacturing testing process has not yet reached three-sigma quality levels.
Since we have this let use the special consideration
Three-sigma limits set a range for the process parameter at 0.27% control limits. Three-sigma control limits are used to check data from a process and if it is within statistical control
Therefore,
The 0.27% will give the defective
2.7/100×10=0.027
Then, the none defective is
1-0.027=0.973
Which is 97.3%
49–2ax –a^2–x^2
Extract the negative sign
= 49 - (a^2 +2ax +x^2)
Factor using a^2 + 2ab + b^2 = (a+b)^2
= 49 - (a+x)^2
Factor using a^2 - b^2 = (a-b)(a+b)
= ( 7- (a + x)) * (7 + (a + x))
= ( 7- a - x) * (7 + a + x)
