ElenaW [278]

Answer:

0.74 to 6.06

Step-by-step explanation:

The groups are independnet,

SE(xh bar-xa bar)=sqrt [sh^2/nh+sa^2/na]=sqrt [10.1^2/80+10.3^2/80]=1.61

At df=157, the t critical is 1.65

90%c.i=(xh bar-xa bar)+-tcritical SE(xh bar-xa bar)

=(25.2-21.8)+-1.65*1.61

=0.74 to 6.06

Nolan is deciding between two truck rental companies. Company A charges an initialfee of $90 for the rental plus $2 per mile dri
kotegsom [21]

first we writte the information they are giving to us:

For company A:

initial fee = $90

rent per mile = $2

For combany B:

initial fee = $50

rent per mile = $3

Now for company A the equation that represent the charge in one mile will be: (where n is the number of miles)

\begin{gathered} A=90+2(n) \\ A=90+2(1) \\ A=90 \end{gathered}

And for company B:

\begin{gathered} B=50+3n \\ B=50+3(1) \\ B=53 \end{gathered}

Now to determine the number miles driven, that would make the cost of each company the same, we have to make A = B

\begin{gathered} A=B \\ 90+2n=50+3n \\  \end{gathered}

and finaly we can solve for n

\begin{gathered} 90-50=3n-2n \\ 40=n \end{gathered}

so if they drive for 40 miles the will pay the same
