Answer:
a) 106
b) 53
Step-by-step explanation:
Minimum required medical files can be found using the formula
n≥ p×(1-p) × 
where
- n is the minimum required medical files
- p is the estimated proportion for blood type b
- z is the corresponding z-score for two tailed 85% confidence level
- ME is the margin of error in the estimation
For the case (a)
If there is no preliminary estimate for p, then it is estimated as p=0.5
corresponding z-score for two tailed 85% confidence level is 1.44
and ME is 0.07.
Putting all in the formula;
n≥ 0.5×0.5 × 
≈ 106
For the case (b)
The only difference is p=
≈0.144
n≥ 0.144×0.856 × ≈ 53

Answer:24v+24w-16
Step-by-step explanation:
8(3v+3w-2)
8 times 3 =24
So 24v+24w
Then 8 times 2=16
So the answer would be 24v+24w-16
Answer:
x equals plus or minus square root of 5 minus 1
Step-by-step explanation:
we have
Divide by 2 the coefficient of the x-term
squared the number
Adds both sides
Rewrite as perfect squares
take the square root both sides
therefore
x equals plus or minus square root of 5 minus 1
