B) Survey several more random samples of 25 people each from people in the town who are registered to vote

C) Survey serveral more random samples of 25 people each from the Republican voters in town

D) Survey a random sample of 25 people who are registered to vote in another town

Answer:
so the answer is C because 25 people each from republican.

Caroline needed to get her computer fixed. She took it to the repair store. The technician at the store worked on the computer for 2.75 hours and charged her $114 for parts. The total was $320.25. Write and solve an equation which can be used to determine xx, the cost of the labor per hour.

For what values of a does the equation ax^2+x+4=0 have only one real solution?

Is f(x)=7-2x a polynomial function

Please help number 7 and number 8

Write code to complete doublepennies()'s base case. sample output for below program: number of pennies after 10 days: 1024 note: these activities may test code with different test values. this activity will perform three tests, with starting pennies = 1 and userdays = 10, then with starting pennies = 1 and userdays = 40, then with startingpennies = 1 and userdays = 1. see how to use zybooks. also note: if the submitted code has an infinite loop, the system will stop running the code after a few seconds, and report "program end never reached." the system doesn't print the test case that caused the reported message.

**Answer:**

And we can find this probability with this difference:

And in order to find these probabilities we can use tables for the normal standard distribution, excel or a calculator.

**Step-by-step explanation:**

**Previous concepts**

**Normal distribution**, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The **Z-score** is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".

**Solution to the problem'**

Let X the random variable that represent the hous spent studying the week before final exams of a population, and for this case we know the distribution for X is given by:

Where and

We are interested on this probability

And the best way to solve this problem is using the normal standard distribution and the z score given by:

If we apply this formula to our probability we got this:

And we can find this probability with this difference:

And in order to find these probabilities we can use tables for the normal standard distribution, excel or a calculator.

**Answer:**

2x4x1 is 8, but if you're wanting x's value, it's 2.

**Answer:**

8 cups

**Step-by-step explanation:**

Let the total batch of salsa be x.

x = 5.2

x = × 5.2

x = 8

8 cups of tomatoes...

application of the quadratic formula.

**Answer:**

**Option (2) **

**Step-by-step explanation:**

For a quadratic equation,

ax² + bx + c = 0

roots of this equation can be determined by using quadratic formula,

x =

Comparing this quadratic equation with the given equation,

y = 2x² - 5x + 18 = 0

a = 2

b = (-5)

c = 18

By substituting these values in the given formula,

x =

Therefore,** Option (2) will be the answer.**
