We learned in Chapter 13, Exercise 35 that the Paralyzed Veterans of America recently sent letters to a random sample of 100,000

Olegator [25]

Answer:

Step-by-step explanation:

given that the Paralyzed Veterans of America recently sent letters to a random sample of 100,000 potential donors and received 4781 donations

$H_0: p = 0.05\\H_a: p$

(left tailed test)

Sample proportion = $\frac{4781}{100000} \\=0.04781$

p difference = -0.00219

Assuming H0 to be true, std error of proportion

= $\sqrt{\frac{pq}{n} } \\=0.00158$

Test statistic Z = p diff/std error = -1.38641

p value = 0.0828

since p value >0.05 our significance level

we accept null hypothesis

There is no statistical evidence of a real drop in the contribution rate.

Please help. Thank you.

Marysya12 [62]

The answer would be 24pi inches.

You can find this by using the formula for a circumference and plugging in the value of the radius.

C = 2pi*r

C = 2pi * 12

C = 24pi

Which of the following ordered pairs belongs to the graph of f(x)

Lera25 [3.4K]

Answer:

The second choice, $(-1,\, 12)$ .

Step-by-step explanation:

Note, that the expression $y = f(x)$ is an equation. A point $(x,\, y)$ is on the graph of $y = f(x)\!$ if and only if the value of $x$ and $y$ satisfy this equation; that is: in other words, the $y\!$ -coordinate of that point (the second number in the tuple) should be equal to $f(x)$ , which is equal to $(-3\, x +9)$ (evaluated where $x\!$ is equal to the first number in the tuple.

For each tuple in the choices, calculate the value of $f(x)$ where $x$ is equal to the first number of each tuple. Compare the result to the second number in that tuple. That choice corresponds to a valid point on $y = f(x)$ only if these two numbers match.

First choice: $x = 1$ , $f(x) = f(1) = -3 + 9 = 6$ . That's not the same as the second number, $-10$ . Therefore, this point isn't on the graph of $y = f(x)$ .
Second choice: $x = -1$ , $f(x) = f(-1) = (-3)\times (-1) + 9 = 3 + 9 = 12$ . That matches the second number in the tuple. Therefore, this point is on the graph of $y = f(x)$ .
Third choice: $x = 2$ , $f(x) = f(2) = (-3)\times 2 + 9 = 3$ . That's not the same as the second number, $(-3)$ . Therefore, this point isn't on the graph of $y = f(x)$ .
Fourth choice: $x = -2$ , $f(x) = f(-2) = (-3)\times (-2) + 9 = 15$ . That's not the same as the second number, $13$ . Therefore, this point isn't on the graph of $y = f(x)$ .

Identify the coefficient of each term of the polynomial.

fredd [130]

There are two parts of an equation (including this one), the coefficient, and the variable.
The coefficient is a known number, written as a digit, whereas the variable is an unknown number, written as a letter to signify an unknown number.

So, the coefficient in the first term (or part of the equation) is -2. The coefficient in the second term is 9, and the variable in this equation is x.
