The answer would be x^2-18x+81. This can be found be writing "(x-9)^2" twice, and distributing. Combine like terms, and you should get this answer.
it's 0.4 while it may look like 4% it's actually 40% of 1
Solution :
The data is normally distributed.
The standard deviation is 18 days
Here the data is normally distributed and 54 days is 3 days of standard deviation.
Therefore, the percentage of the births that would be 
within the 54 days of the mean 
length is given by :
= P( -3 < Z < 3)
= 0.9544
= 95 %
Therefore, about 95% of the births would be within 54 days of the men length.
Answer:
<h2>96 and 48</h2>
Step-by-step explanation:
To solve this problem we have to find the largest possible greatest common factor, which is 48.
Now, numbers 96 and 48 have as Greatest Common Factor 48, that's the largest number possible that is common to both numbers because
48/48 = 1
96/48 = 2
Therefore, the answer is 96 and 48, because they don't have repetitive digits.
So, let’s find out the numbers needed to form the ratio. The length of the swimming pool is 50 ft long. We need to find the perimeter. 2(50+35)
2*85
170.
So, the perimeter is 170 ft. Now we need to form the ratio. Length is first, then the perimeter.
50:170 is your ratio, but we can simplify it to 5:17. Hope this helped!
