Answer:

g = -2

Step-by-step explanation:

g = -5r + 13

r = 3

You substitute three for r in the equation.

--------------------------------------------------------------

g = -5(3) + 13

--------------------------------------------------------------

Distribute -5 to 3

--------------------------------------------------------------

g = -15 + 13

--------------------------------------------------------------

Solve

-------------------------------------------------------------

g = -15 + 13

-15 + 13 = -2

g = -2

An article regarding interracial dating and marriage recently appeared in the Washington Post. Of the 1,709 randomly selected ad
VMariaS [17]

Answer:

The 95% confidence interval for the percent of all black adults who would welcome a white person into their families is (0.8222, 0.8978).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of \pi, and a confidence level of 1-\alpha, we have the following confidence interval of proportions.

\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}

In which

z is the zscore that has a pvalue of 1 - \frac{\alpha}{2}.

For this problem, we have that:

323 blacks, 86% of blacks said that they would welcome a white person into their families. This means that n = 323, p = 0.86

95% confidence level

So \alpha = 0.05, z is the value of Z that has a pvalue of 1 - \frac{0.05}{2} = 0.975, so Z = 1.96.

The lower limit of this interval is:

\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.86 - 1.96\sqrt{\frac{0.86*0.14}{323}} = 0.8222

The upper limit of this interval is:

\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.86 + 1.96\sqrt{\frac{0.86*0.14}{323}} = 0.8978

The 95% confidence interval for the percent of all black adults who would welcome a white person into their families is (0.8222, 0.8978).

The si unit of measure for length—the meter—would be most appropriate when
Semenov [28]

There are seven SI base units which are used in science, every unit has its own property or use:

Meter (length)

Kilogram (mass)

Second (time)

Kelvin (temperature)

Mole (amount of substance)

Ampere (electrical unit) and

Candela (luminous intensity)

<span>The SI unit of measure for length (meter) would be most appropriate when we are measuring the distance between two places or when we are taking measurement of something.</span>
