A magazine provided results from a poll of 1000 adults who were asked to identify their favorite pie. Among the 1000 ​responde

nts, 14​% chose chocolate​ pie, and the margin of error was given as +3 percentage points. What values do ​, ​, ​n, E, and p​ represent? If the confidence level is ​%, what is the value of ​?

The completion of the tabs are:

  • The value of \bar p is the sample proportion.
  • The value of  \bar q is found by evaluating 1-\=p
  • The value of n is the sample size.
  • The value of E is the margin of error.
  • The value of p is the population proportion.
  • α = 0.05.

<h3>What is the margin of error.?</h3>

You may calculate how many percentage points your findings will deviate from the actual population figure by using something called a margin of error.

In conclusion

  • The worth of p^ is the fraction of the sample.
  • The worth of p^ is discovered by assessing
  • The sample size is given by the number n.
  • The margin of error is expressed as E's value.
  • The population percentage is represented by the value of p.
  • α = 0.05.

In conclusion,

What are the roots of the equation x^2+6x-9=0
Mila [183]

Answer:

x = approx. 1.24 or -7.24

Step-by-step explanation:

It's hard to factor directly so we should use the quadratic formula or complete the square. I'm going to go with completing the square.

x²+6x-9=0

x²+6x=9

x²+6x is the same as x²+2·3·x, in order to make this into the algebraic identity (A+B)²=A²+2AB+B², we must add B², or in this case 3² to both sides. (A is x, B is 3)

x²+6x+9=18

(x+3)²= 18

x+3= ±√18

x= ±4.24 -3 (approximately 4.24)

First solution for  x = 4.24-3 = 1.24

Second solution for x = -4.24-3 = -7.24

factor completely 4x5 − 20x4 − 36x3. 4(x5 − 5x4 − 9x3) x3(4x2 − 20x − 36) x2 − 5x − 9 4x3(x2 − 5x − 9)
Mila [183]

Consider the polynomial 4x^5 - 20x^4 - 36x^3. It has three terms and their greatest common factor is 4x^3.

Since

4x^5=4x^3\cdot x^2,\\20x^4=4x^3\cdot 5x,\\36x^3=4x^3\cdot 9,

then

4x^5 - 20x^4 - 36x^3=4x^3(x^2-5x-9) (you write in brackets the same sign as the corresponding term has).

Answer: correct choice is D.

If line segment AB represents ​25%, what is the length of a line segment that is​ 100%?
kicyunya [14]

If I am correctly understanding the question, I think the length of the line segment would be 4AB

Step-by-step explanation:

25% = 1/4

AB = 1/4

100% = 4/4

AB*4 = 4AB

Multiply AB by 4 to find the value that 100% would equal, resulting in 4AB.
