1.65

You can substitute in the values of p, n and e to get the equation:
5700 = 4000c - 900

add 900 to both sides and you get

6600 = 4000c

divide both sides by 4000 and you get

1.65 = c

so the answer is 1.65

16. A large-sample 95 percent confidence interval for the proportion of credit
borishaifa [10]

Answer:

(B) 0.057

Step-by-step explanation:

The 95% confidence interval is (0.028, 0.086). The formula for the confidence interval is μ ± e where μ is the mean and e is the margin of error.

Therefore the confidence interval is (μ - e , μ + e).

That is μ - e = 0.028 and μ + e = 0.086

To get the point estimate which is the mean, we sum the two proportions and divide it by two.

Therefore point estimate (μ) = (0.028 + 0.086) / 2 = 0.057

Answer:

The equation of the quadratic function shown is;

x^2+ 2x -3

Step-by-step explanation:

Here in this question, we need to know the quadratic equation whose graph was shown.

The key to answering this lies in knowing the roots of the equation.

The roots of the equation are the solution to the quadratic equation and can be seen from the graph at the point where the quadratic equation crosses the x-axis.

The graph crosses the x-axis at two points.

These are at the points x = -3 and x = 1

So what we have are;

x + 3 and x -1

Multiplying both will give us the quadratic equation we are looking for.

(x + 3)(x-1) = x(x -1) + 3(x-1)

= x^2 -x + 3x -3 = x^2 + 2x -3
