Determine the standard form of the equation of the line that passes through (-2, 0) and (-8,5)

Naya [18.7K]

Answer:

$-5x-6y=10$ ← in standard form

Step-by-step explanation:

The equation of a line in standard form is.

$Ax+By=C$

were

A is a positive integer and

B, C are integers

As the equation in point-slope form

$y-y_1=m\left(x-x_1\right)$

where m is the slope and $\left(x_1,\:y_1\right)$ is a point on the line.

as

$\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$\left(x_1,\:y_1\right)=\left(-2,\:0\right),\:\left(x_2,\:y_2\right)=\left(-8,\:5\right)$

$m=\frac{5-0}{-8-\left(-2\right)}$

$m=-\frac{5}{6}$

using $m=-\frac{5}{6}$ and $\left(x_1,\:y_1\right)=\left(-2,\:0\right)$ then

$y-0=-\frac{5}{6}\left(x-\left(-2\right)\right)$

$-\frac{5}{6}\left(x-\left(-2\right)\right)=y-0$

$6\left(-\frac{5}{6}\left(x-\left(-2\right)\right)\right)=6y$

$-5\left(x+2\right)=6y$

$-5x-10=6y$

$-5x-6y=10$ ← in standard form

What is the slope of the linear table below?

Luden [163]

Answer:

A

Step-by-step explanation:

Calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (- 3, 8) and (x₂, y₂ ) = (0, 10) ← 2 ordered pairs from the table

m = $\frac{10-8}{0+3}$ = $\frac{2}{3}$ → A

In an article in Marketing Science, Silk and Berndt investigate the output of advertising agencies. They describe ad agency outp

fredd [130]

Answer: (7.27%, 7.55%)

Step-by-step explanation:

As per given , we have

Sample size : n= 392

Sample mean : $\overline{x}=7.41\%$

$\sigma=1.43\%$

Critical two-tailed z-value for 95% confidence = $z_{\alpha/2}=1.96$

Required confidence interval would be :

$7.41\%\pm (1.96)\dfrac{1.43\%}{\sqrt{392}}\\\\=7.41\%\pm 0.14\%\\\\=(7.27\%, 7.55\%)$

Hence, the required 95% confidence interval for the mean percentage share of billing volume from network television for the population of all U.S. advertising agencies : (7.27%, 7.55%)
