What number line model represents the expression 2.5+4.5 Choose 1 answer: A, B, or C?

a_sh-v [17]

Answer:

Step-by-step explanation:

Because, the first point will be plotted at 2.5 (each line is 1 which means like line after 0 is 1, the next one is 2, and so one). When you add 2.5 with 4.5 it equals to 7 which means the next point will be placed at 7. (right behind 8)

Describe the sampling distribution of p(hat). Assume the size of the population is 30,000.n=800, p=0.6a) Determine the mean of t

Leno4ka [110]

Answer:

Standard deviation of the binomial distribution

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

Step-by-step explanation:

Explanation:-

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