Find the probability of no successes in six trials of a binomial experiment in which the probability of success is 30%. round to the nearest tenth of a percent.

There is 11.76% chances that there is no success in six trials.

Step-by-step explanation:

Since we have given that

Probability of success = 30%

Probability of no success is given by

100-30=70%

Number of trials = 6

And we need probability of no success in 6 trials.

We will use "Binomial distribution",

Hence, there is 11.76% chances that there is no success in six trials.

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )
