Acoin is to be tossed 36 times what are the mean and standard deviation of the number of heads

Binomial distribution,

n = 36 independent events,

p = 0.5 probability of success and of failure, as 1-p = p.

Mean of binomial distribution is np=18.

Variance is np(1-p)=9

Standard deviation is sqrt(variance)=3.

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

let's solve your equation step-by-step.

24−3x=−27

step 1: simplify both sides of the equation.

24−3x=−27

24+−3x=−27

−3x+24=−27

step 2: subtract 24 from both sides.

−3x+24−24=−27−24

−3x=−51

step 3: divide both sides by -3.

−3x

−3

=

−51

−3

x=17

answer:

x=17
