Step-by-step explanation:
.89 per pound
3.2 pounds
.89*3.2 = 2.85
Answer:
0.2508
Step-by-step explanation:
The question asks for a conditional probability.
P(a household owns a dog if it owns a pet) = 0.67
Then P(a household does not own a dog if it owns a pet) = 1 - 0.67 = 0.33
P(a household owns a cat if it owns a pet) = 0.24
Then P(a household does not own a cat if it owns a pet) = 1 - 0.24 = 0.76
P(if a household owns a pet but the pet is not a cat or dog) = P(if a household owns a pet, it does not own a cat) × P(if a household owns a pet, it does not own a dog) = 0.33 × 0.76 = 0.2508
Answer:
Step-by-step explanation:
First let's multiply both sides by 2 to remove the 
fraction:
Next, let's divide both sides by 
:
Finally, let's subtract 
from both sides:
Answer: d. 15.49
Step-by-step explanation:
Given : The random variable K has a geometric distribution with mean 16.
Formula for Mean and standard deviation in geometric distribution:
(1)
(2), where p is the probability of success in each trial.
Since 
(Given)
Then from (1) ,
Put value of p in (2),
Hence, the standard deviation of random variable K is closest to 15.49.
Therefore , the correct answer is d. 15.49 .
