Answer:
66
Step-by-step explanation:
The pathogenicity of the protein encoding mutations was predicted using a ... These are then amplified to the required number of mtDNA molecules in ... n = 54) followed by age-associated mutations (0.513±0.323, n = 66) and ... Further, frequency of age-related mtDNA mutations in each gene
I tryed my best to figure out what all of the numbers were. if i got any wrong then please tell me and i will put the right answer in the comments.
1) 3/5= 5/x (cross multiply)
3x=5(5)
3x=25
x= 25/3 -or- 8.33
2) 2/4=x/12<span> (cross multiply</span><span>)
</span> 2(12)=4x
24=4x
6=x
3) 10/x=5/9<span> (cross multiply</span><span>)
10(9)=5x
90=5x
18=x
4) 5/5=x/18</span><span> (cross multiply</span><span>)
5(18)=18x
90=18x
5=x</span>
Answer:
![(x - 2y)((x - 2y) - 4) + 4](https://tex.z-dn.net/?f=%28x%20-%202y%29%28%28x%20-%202y%29%20-%204%29%20%2B%204)
Step-by-step explanation:
Given
![x^2 - 4xy - 4x + 4y^2 + 8y + 4](https://tex.z-dn.net/?f=x%5E2%20-%204xy%20-%204x%20%2B%204y%5E2%20%2B%208y%20%2B%204)
Required
Factorize
![x^2 - 4xy - 4x + 4y^2 + 8y + 4](https://tex.z-dn.net/?f=x%5E2%20-%204xy%20-%204x%20%2B%204y%5E2%20%2B%208y%20%2B%204)
Rearrange
![x^2 - 4xy + 4y^2- 4x + 8y + 4](https://tex.z-dn.net/?f=x%5E2%20-%204xy%20%2B%204y%5E2-%204x%20%20%2B%208y%20%2B%204)
Group into three
![(x^2 - 4xy + 4y^2)- (4x - 8y) + (4)](https://tex.z-dn.net/?f=%28x%5E2%20-%204xy%20%2B%204y%5E2%29-%20%284x%20%20-%208y%29%20%2B%20%284%29)
Factorize the first bracket
![(x^2 - 2xy- 2xy + 4y^2) - (4x - 8y) + (4)](https://tex.z-dn.net/?f=%28x%5E2%20-%202xy-%202xy%20%2B%204y%5E2%29%20-%20%284x%20%20-%208y%29%20%2B%20%284%29)
![x(x - 2y) - 2y(x - 2y)- (4x - 8y) + (4)](https://tex.z-dn.net/?f=x%28x%20-%202y%29%20-%202y%28x%20-%202y%29-%20%284x%20%20-%208y%29%20%2B%20%284%29)
![(x - 2y)(x - 2y) - (4x - 8y) + (4)](https://tex.z-dn.net/?f=%28x%20-%202y%29%28x%20-%202y%29%20-%20%284x%20%20-%208y%29%20%2B%20%284%29)
Factorize the second bracket
![(x - 2y)(x - 2y) - 4(x - 2y) + 4](https://tex.z-dn.net/?f=%28x%20-%202y%29%28x%20-%202y%29%20-%204%28x%20%20-%202y%29%20%2B%204)
x - 2y is a common factor of ![(x - 2y)(x - 2y) - 4(x - 2y)](https://tex.z-dn.net/?f=%28x%20-%202y%29%28x%20-%202y%29%20-%204%28x%20%20-%202y%29)
So, the expression becomes
![(x - 2y)((x - 2y) - 4) + 4](https://tex.z-dn.net/?f=%28x%20-%202y%29%28%28x%20-%202y%29%20-%204%29%20%2B%204)
The expression cannot be further simplified;
<em>Hence, </em>
<em> is equivalent to </em>
<em></em>
Answer:
y=−3
Step-by-step explanation:
5:2 is basically the same as 14:35
To get to 5 you have to multiply 2 by 2.5 and 14 times 2.5 is 35
