Answers

Answer:

-3/19

Step-by-step explanation:

Given data

We have the coordinates

(12, 2), (-7,5)

x1=12

y1=2

x2=-7

y2=5

The expression for the slope is given as

Slope= y2-y1/x2-x1

Substiute

Slope=  5-2/-7-12

Slope= 3/-19

Hence the slope is -3/19

Answers

Answer:

(1.962 ; 2.578) ;

There is a 95% chance that the true population mean of the number of children of all couples who have been married for 7 years lies within the interval (1.962 ; 2.578);

(1.865 ; 2.675);

There is a 99% chance that the true population mean of the number of children of all couples who have been married for 7 years lies within the interval (1.8646 ; 2.6754)

Step-by-step explanation:

Given the data :

0, 0, 0, 0, 0, 0, 0, 1, 1, 1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 4, 4, 4, 4, 4, 4, 4, 5

Using calculator :

Mean, xbar = 2.27

Standard deviation, s = 1.219

Sample size = 60

Confidence interval :

Xbar ± Margin of error

Margin of Error = Zcritical * s/sqrt(n)

Zcritical at 95% = 1.96

Margin of Error = 1.96 * 1.219/ sqrt(60) = 0.3084

Lower boundary = (2.27 - 0.3084) = 1.962

Upper boundary = (2 27 + 0.3084) = 2.578

(1.962 ; 2.578)

There is a 95% chance that the true population mean of the number of children of all couples who have been married for 7 years lies within the interval (1.962 ; 2.578)

C.) 99% confidence interval :

Xbar ± Margin of error

Margin of Error = Zcritical * s/sqrt(n)

Zcritical at 99% = 2.576

Margin of Error = 2.576 * 1.219/ sqrt(60) = 0.4054

Lower boundary = (2.27 - 0.4054) = 1.8646

Upper boundary = (2.27 + 0.4054) = 2.6754

(1.865 ; 2.675)

There is a 99% chance that the true population mean of the number of children of all couples who have been married for 7 years lies within the interval (1.8646 ; 2.6754)

Answers

Answer:

[tex]x=-4+\sqrt{2}[/tex]

[tex]x=-4-\sqrt{2}[/tex]

Step-by-step explanation:

The quadratic formula is an equation that can be used to find the roots of a quadratic equation when one is given the equation in standard form. A quadratic equation in standard form is the following,

[tex]ax^2 +bx + c=0[/tex]

The quadratic formula is the following,

[tex]\frac{(-a)(+-)\sqrt{(x)^2-4(b)(c)}}{2(a)}[/tex]

Substitute in the given coefficients for the following equation,

[tex]2x^2 + 16x + 28 = 0[/tex]

Substitute,

[tex]\frac{-16(+-)\sqrt{(16)^2-4(2)(8)}}{2(2)}[/tex]

Simplify,

[tex]\frac{-16(+-)\sqrt{256-224}}{4}\\\\=\frac{-16(+-)\sqrt{32}}{4}\\\\=\frac{-16(+-)4\sqrt{2}}{4}\\\\=-4(+-)\sqrt{2}[/tex]

The roots of the quadratic equation ([tex]2x^2+16x+28=0[/tex]) are  ([tex]x=-4+\sqrt2[/tex]) and ([tex]x=-4-\sqrt{2}[/tex])

A university researcher wants to estimate the mean number of novels that seniors read during their time in college. An exit survey was conducted with a random sample of 9 seniors. The sample mean was 7 novels with standard deviation 2.29 novels. Assuming that all conditions for conducting inference have been met, what is a 95 percent confidence interval for the population mean number of novels read by all seniors?

Answers

Answer:

(5.240 ; 8.760)

Step-by-step explanation:

Given :

Sample mean, xbar = 7

Standard deviation, s = 2.29

Sample size, n = 9

95% confidence interval for the population mean :

Confidence interval :

Xbar ± Margin of error

Margin of Error = Tcritical * s/sqrt(n)

Tcritical at 0.05 ; df = 8 = 2.306

Margin of Error = 2.306 * 2.29/sqrt(9)

Margin of Error = 1.760

Lower boundary = (7 - 1.760) = 5.240

Upper boundary = (7 + 1.760) = 8.760

(5.240 ; 8.760)
