About 40%of babies born with a certain ailment recover fully. a hospital is caring for sevenbabies born with this ailment. the random variable represents the number of babies that recover fully. decide whether the experiment is a binomial experiment. if it is, identify a success, specify the values of n, p, and q, and list the possible values of the random variable x.

Step-by-step explanation:

Given that about 40%of babies born with a certain ailment recover fully. A hospital is caring for seven babies born with this ailment.

Each baby is independent of the other and there are exactly two outcomes, recover and not recover.

Hence this experiment is a binomial experiment.

Success is a child getting recovered from this ailment.

p = Probability for any one child to get success = 0.40

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

i think the correct option is the second option.
