Use intercepts to graph the line described by each equation. -6y=-4x+24

Aloiza [94]

First, you have to get the equation to the normal form of a line. To do this, you divide both sides by -6 to get $\frac{2}{3} x-4$ . The y-intercept is at -4 and your slope is 2/3. Use this to graph the equation.

Answer:

x = 50, y = 10

Step-by-step explanation:

$\\(5x-100)+(x-20) = 180 => 6x = 300 => x = 50\\(3y)+(y+140) = 180 => 4y = 40 => y = 10$

Answer: $p-value \approx 0.01$

Step-by-step explanation:

Hypothesis testing

$\\\left\{\begin{matrix}H_0 : \mu_0 =0\\ H_1: \mu_0 \neq 0\end{matrix}\right.\\$

For this problem, we need to use the t-student distribution to make inference about the data. We calculate the t-statistics as below:

$\bar{X} = 20\:\mu m\\S.E. = 60\:\mu m\\n=82\\t_{stat} = \frac{\bar{X}-\mu_0}{S.E/\sqrt{n}}=\frac{20-0}{60/\sqrt{82}}=3.0185$

Using a t-statistics table, or using the function TDIST in Microsoft Excel with $t_{stat} = 3.0185,\: df (degree\: of\: freedom) = 14 - 1 = 13$ with two-tailed distribution, we obtain $p-value \approx 0.01$ .
