Answer:

Standard deviation of the binomial distribution

= $\sqrt{n p q} = \sqrt{192} = 13.856$

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given size 'n' = 800

The population proportion 'p'=0.6

Let 'X' be the random variable of the binomial distribution

a) mean of the binomial distribution = n p = 800 ×0.6

μ = 480

b) variance of the binomial distribution

= n p q

= 800 X 0.6 ×0.4

σ² = 192

Standard deviation of the binomial distribution

σ = $\sqrt{n p q} = \sqrt{192} = 13.856$

F) One number is 78 more than

vladimir2022 [97]

Answer:

The larger number = 116

Step-by-step explanation:

Let the smaller number = x

Given that one number is 78 more than another, so

The larger number = x+78

Given that if we add 12 to the smaller number, the result is 50, so

$x+12=50$

subtract 12 from both sides

$x+12-12=50-12$

Simplify

$x=38$

Therefore,

The smaller number = 38

The larger number = x+78 = 38+78 = 116

Thus, the larger number = 116
