The city of Raleigh has 11700 registered voters. There are two candidates for city council in an upcoming election: Brown and Fe
Vesnalui [34]

Answer:

The sample statistic for the proportion of voters surveyed who said they'd vote for Brown is 0.308.

The expected numbers of voters who would vote for Brown is 3604.

Step-by-step explanation:

The sample statistic is a numerical quantity used to represent a characteristic of a sample. For example, sample mean is a sample statistic representing the average of the sample. Or, sample proportion is a sample statistic representing the proportion of a particular variable in the sample. Or sample variance is a sample statistic representing the variance of the sample.

The sample statistic can be used to estimate the population parameter.

They are known as the point estimate of the parameter.

The sample proportion of a variable <em>X</em> is given by:

\hat p=\frac{X}{n}

It is provided that of the <em>n</em> = 250 registered voters selected, the number of voters who said they would vote for Brown is <em>X </em>= 77.

Compute the sample statistic for the proportion of voters surveyed who said they'd vote for Brown as follows:

\hat p=\frac{X}{n}

  =\frac{77}{250}\\

  =0.308

Thus, the sample statistic for the proportion of voters surveyed who said they'd vote for Brown is 0.308.

Compute the expected number of people of the 11700 registered voters who would vote for Brown as follows:

E(X)=N\times \hat p

         =11700\times 0.308\\=3603.6\\\approx 3604

Thus, the expected numbers of voters who would vote for Brown is 3604.

Match the pairs of values of f(x) and g(x) with the corresponding values of h(x) if h(x) = f(x) ÷ g(x). Tiles f(x) = x2 − 9, and
vitfil [10]
For this case we must solve each of the functions.
 We have then:

 f (x) = x2 - 9, and g (x) = x - 3
 h (x) = (x2 - 9) / (x - 3)
 h (x) = ((x-3) (x + 3)) / (x - 3)
 h (x) = x + 3

 
f (x) = x2 - 4x + 3, and g (x) = x - 3
 
h (x) = (x2 - 4x + 3) / (x - 3)
 h (x) = ((x-3) (x-1)) / (x - 3)
 h (x) = x-1

 f (x) = x2 + 4x - 5, and g (x) = x - 1
 h (x) = (x2 + 4x - 5) / (x - 1)
 h (x) = ((x + 5) (x-1)) / (x - 1)
 h (x) = x + 5

 f (x) = x2 - 16, and g (x) = x - 4
 h (x) = (x2 - 16) / (x - 4)
 h (x) = ((x-4) (x + 4)) / (x - 4)
 h (x) = x + 4
