In the US, 21% of households use a clothesline to dry their laundry. Capucine would like to survey households that use a clothesline, so she plans to contact randomly selected US households until she finds ones that use one. Let F be the number of households Capucine contacts to reach the first household that uses a clothesline. Find the mean and standard deviation of F. Find the mean and standard deviation of F ANSWER: Mean: 4.84
Standard deviation: 4.24

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:  

1- c
