Step-by-step explanation:
The scientific notation:

<em>1 ≤ a < 10</em> and <em>k -</em><em> any integer number</em>
<em />

Answer: a) 1082, b) wider.
Step-by-step explanation:
Since we have given that
Margin of error = 0.1 millimeter = E
Standard deviation = 2 mm = σ
Critical value would be

a) Sample size would be

b) Sample size, n = 100
So, the margin of error would be

Since the margin of error in b part is more than a part, as we know that the higher the margin of error, the wider the confidence interval.
So, it would have wider confidence interval.
Hence, a) 1082, b) wider.
Ok to find this answer you first have to subtract the 16 from the 30 to find what "CB" is, which is 14. From there subtract 14 and 16 from 49 to find that the whole answer is 35. I think that is the answer but I'm not positive.
Answer:
y= 2x=2/5x - 3
Step-by-step explanation:
swap the variables: y=3x+25x−2 becomes x=3y+25y−2.
Now, solve the equation x=3y+25y−2 for y.
