Nbc news reported that 1 in 20 children in the u. s. has a food allergy.† consider selecting 15 children at random. define the random variable x asx = number of children in the sample of 15 that have a food allergy. find the following probabilities. (round your answers to three decimal )p(x < 3)(b)p(x ? 3)(c)p(x ? 4)(d)p(1 ? x ? 3)

yes

step-by-step explanation:

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours
