In a recent survey 75 of the community favored building a police substation in their neighborlhood. If 20 citizens are chosen. W

Anton [14]

Answer:

Mean = 15

Standard deviation = 1.94

Step-by-step explanation:

We are given the following information:

We treat favoring of building a police substation as a success.

P(Success) = 75% = 0.75

Then the number of citizens follows a binomial distribution, where

$P(X=x) = \binom{n}{x}.p^x.(1-p)^{n-x}$

where n is the total number of observations, x is the number of success, p is the probability of success.

Now, we are given n = 20

We have to find the mean and the standard deviation.

$\mu = np = 20(0.75 ) = 15\\\sigma = \sqrt{np(1-p)} = \sqrt{20(0.75)(1-0.75)} = 1.94$

Thus, the mean of favoring the substation is 15 and the standard deviation of favoring substation is 1.94

The height of a sunflower can be modeled by the expression H (1.02)t where t represents the number of years since it was planted

Irina18 [472]

Answer:

Step-by-step explanation:

Giveb the model expression :

H = (1.02)^t

General relation:

H = (1 + rate)^t

Rate = yearly growth rate of sunflower

1 + rate = 1.02

Rate = 1.02 - 1

Rate = 0.02

Hence yearly growth rate of sunflower is :

0.02 * 100%

= 2%

2% growth per year.
