D=20mi, r=30 mi/h, what is the time

il63 [147K]

$v=\frac{s}{t}\\\\v=30\ mph\\\\s=20\ mi\\\\subtitute\\\\30=\frac{20}{t}\to\frac{30}{1}=\frac{20}{t}\ \ \ |cross\ multiply\\\\(30)(t)=(1)(20)\\\\30t=20\ \ \ \ |divide\ both\ sides\ by\ 30\\\\t=\frac{20}{30}\to \huge\boxed{t=\frac{2}{3}\ (h)}$

$1\ h=60\ min\\\\therefore\\\\\frac{2}{3}\ h=\frac{2}{3}\cdot60\ min=2\cdot20\ min=\huge\boxed{40\ min}$

When Stephan moved from Illinois to Florida, his average monthly electric bill increased from $83 to $102. He is curious to know

kondaur [170]

Answer: The z-scores for Stephan's IL and FL electric bills. are -0.625 and 0.75 respectively.

Step-by-step explanation:

Given: Average monthly electric bill in Illinois = $83

Average monthly electric bill in Florida = $102

Formula of z : $z=\dfrac{X-mean}{standard\ deviaton}$

In Illinois, the mean monthly electric bill is $85, with a standard deviation of $3.20.

$z=\dfrac{83-85}{3.20}= -0.625$

In Florida, the mean monthly electric bill is $105, with a standard deviation of $4.00.

$z=\dfrac{105-102}{4}=\dfrac{3}{4}=0.75$

Hence, the z-scores for Stephan's IL and FL electric bills. are -0.625 and 0.75 respectively.
