77% of workers know what their CEO looks like. You randomly select six workers and ask each if they know what their CEO looks like. Complete parts (a) through (d) below. (a) Find the mean of the binomial distribution. μ=
(b) Find the variance of the binomial distribution. σ^2=
(c) Find the standard deviation of the binomial distribution σ=
(d) interpret the results the context of the real-life situation.
On average out of 6 workers know what their CEO looks like. The standard deviation is , so in most samples of six workers, the number of workers know what their CEO looks like would differ from the average number by no more than .

Demonstrate the proof of your new polynomial identity through an algebraic proof and a numerical proof in an engaging way! make it so the whole world wants to purchase your polynomial identity and can't imagine living without it! you must: label and display your new polynomial identity prove that it is true through an algebraic proof, identifying each step demonstrate that your polynomial identity works on numerical relationships create your own using the columns below. see what happens when different binomials or trinomials are combined. square one factor from column a and add it to one factor from column b to develop your own identity. column a column b (x − y) (x2 + 2xy + y2) (x + y) (x2 − 2xy + y2) (y + x) (ax + b) (y − x) (cy + d)
