The tread life of tires mounted on light-duty trucks follows the normal probability distribution with a population mean of 60,00

qwelly [4]

Answer:

$S.E=1183.2$

Step-by-step explanation:

From the question we are told that:

Population mean $\mu=60000$

Population standard deviation $\sigma= 14,000 miles.$

Sample size $n=140$

Generally the equation for Standard error is mathematically given by

$S.E=\frac{ \sigma}{ \sqrt n}$

$S.E= \frac{14000}{\sqrt 140}$

$S.E=1183$

What is the equation of the linear model in point-slope form that includes the point (-3,1) and has a slope of 3?

vova2212 [387]

$(\stackrel{x_1}{-3}~,~\stackrel{y_1}{1})\ \qquad \qquad \stackrel{slope}{m}\implies 3 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{1}=\stackrel{m}{3}(x-\stackrel{x_1}{(-3)})\implies y-1=3(x+3)$
