The town of hayward (california) has about 50,000 registered voters. a political scientist takes a simple random sample of 500 of these voters. in the samle, the breakdown by party affiliation is:

republican 115
democrat 331
independent 54

the range from to is a 95% confidence interval for the percentage of independents among fill in the first two blanks with numbers. fill in the last blank with one of the following two options: "all the 50,000 voters in the population", "500 voters in the sample".

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
