It’s the first one - 3x^2 - 3x+8 - 9/x+1
Answer:
x = 
Step-by-step explanation:
given
4 - ax = 2 ( isolate the term in x by subtracting 4 from both sides )
- ax = 2 - 4 = - 2 ( divide both sides by - a )
x =
=

Answer:
(a) Probability = 0.01520
(b) Probability = 0.00028
(c) Probability = 0.96391
Step-by-step explanation:
Total mitochondria = 330
Defective = 6
(a) Without replacement, if the first selection contains a defective mitochondria, we have a total of 5 defective remaining from a total of 329 mitochondria. Thus the probability the second one is defective Given the first one was defective will be :
Probability second is defective given the first one is not = 5 / 329 = 0.01520
(b) The probability the first is defective is : 6 / 330 = 0.01818
The probability the second is defective (without replacement) = 5 / 329 = 0.01520
The probability both are defective = 0.01818 * 0.01520 = 0.00028
(c) Probability the first one is acceptable = 324 / 330 = 0.98182
Probability the second one is acceptable = 323 / 329 = 0.98176
Probability both are acceptable = 0.98182 * 0.98176 = 0.96391
