What is the equation of the line, in point slope form, that passes through the points (4,8) and (2,-2)

Solnce55 [7]

Answer:

Step-by-step explanation:

1) point slope form is:

y-y1=m(x-x1)

y1=8

x1=4

m=(slope)

to find m: y2-y1/x2-x1

hence

-2-8/2-4=-10/-2=5

m=5:

y-8=5(x+4)

An ethanol railroad tariff is a fee charge for shipments of ethanol on public railroads. The Agriculture Marketing Service publi

Stels [109]

Answer:

The appropriate response is "0.9476".

Step-by-step explanation:

The given values are:

Standard deviation,

$\sigma=1150$

Randomly selected railroad-car shipments,

n = 500

As we know,

⇒ $\sigma \bar{x}=\frac{\sigma}{\sqrt{n} }$

On substituting the values, we get

⇒ $=\frac{1150}{\sqrt{500} }$

then,

⇒ $=P(-1.94$

⇒ $=P(Z$

On using the table of P, we get

⇒ $=0.9738 - 0.0262$

⇒ $=0.9476$

If p varies directly as q and q= 70 when p= 10, find q when p = 12

stellarik [79]

$\qquad \qquad \textit{direct proportional variation} \\\\ \textit{\underline{y} varies directly with \underline{x}}\qquad \qquad \stackrel{\textit{constant of variation}}{y=\stackrel{\downarrow }{k}x~\hfill } \\\\ \textit{\underline{x} varies directly with }\underline{z^5}\qquad \qquad \stackrel{\textit{constant of variation}}{x=\stackrel{\downarrow }{k}z^5~\hfill } \\\\[-0.35em] ~\dotfill$

$\stackrel{\textit{"p" varies directly as "q"}}{p~~ = ~~kq}\qquad \textit{we also know that} \begin{cases} q=70\\ p=10 \end{cases}\implies 10=k70 \\\\\\ \cfrac{10}{70}=k\implies \cfrac{1}{7}=k\hspace{15em}\boxed{p=\cfrac{1}{7}k} \\\\\\ \textit{when p = 12, what is "q"?}\qquad 12=\cfrac{1}{7}q\implies 12=\cfrac{q}{7}\implies 84=q$
