Answer: it might be 4 because 5x=20
Step-by-step explanation:
We can use the binomial theorem to find the probability that 0 out of the 15 samples will be defective, given that 20% are defective.
P(0/15) = (15C0) (0.2)^0 (1 - 0.2)^15 = (1)(1)(0.8)^15 = 0.0352
Then the probability that at least 1 is defective is equal to 1 - 0.0352 = 0.9648. This means there is a 96.48% chance that at least 1 of the 15 samples will be found defective. This is probably sufficient, though it depends on her significance level. If the usual 95% is used, then this is enough.
Step-by-step explanation:
To solve this problem, let's set up our equation to solve for x (time to travel 13 miles).
We use this equation to find x. To solve, we divide 13 by 65 to get our answer.
13 ÷ 65 = 0.2
Our answer: 0.2 hours
Answer:
16oz bag, $0.32 saved
Step-by-step explanation:
3.12/12 = 0.26
3.84/16 = 0.24
For the 12-ounce bag, it would be $0.26 per ounce. For the 16-ounce bag, it would only be $0.24 per ounce.
16*0.26=4.16
4.16 - 3.84 = 0.32
