The mean of the samples is 28.25.

The median of the samples is 28.5

The mode of the samples is 35

The standard deviation of the samples is 5.47.

<h3>Mean of the data points</h3>

The mean for highway mileage (mpg) for a sample of 8 different models of a car company is calculated as follows;

mean = (19 + 22, 26, 27, 30, 32, 35, 35)/8

mean = 28.25

<h3>Median of the data points</h3>

The median is calculated as;

median = (27 + 30)/2 = 28.5

<h3>Mode of the data points</h3>

mode = 35 (it has the highest frequency)

<h3>Standard deviation</h3>

∑(x - x')² = (19 - 28.25)²  +  (22 - 28.25)² + (26 - 28.25)² + (27 - 28.25)² + (30 - 28.25)²  + (32 - 28.25)² + (35 - 28.25)² + (35 - 28.25)²

∑(x - x')² = 239.5

S.D = √[(∑(x - x')² / N]

S.D = √(239.5/8)

S.D = 5.47

The length,AB of the rectangular lot is 1 foot less than two times its width, BC. If the perimeter of the rectangular lot 394 fe
r-ruslan [8.4K]

Answer:

AB=131\ ft

Step-by-step explanation:

we know that

The perimeter of the rectangular lot is

P=2(AB+BC) ----> equation A

where

AB is the length

BC is the width

we have

AB=2BC-1 ---> equation B

P=394\ ft ----> equation C

substitute equation B and equation C in equation A

394=2(2BC-1+BC)

solve for BC

394=2(3BC-1)

394=6BC-2

6BC=396

BC=66\ ft

<em>Find the value of AB</em>

AB=2BC-1

AB=2(66)-1

AB=131\ ft

Is 16=3 one, no, or many solutions?
elixir [45]

Answer:

No solutions; parallel

Step-by-step explanation:

The equations x=16 and x=3 both have a slope of 0. So when graphed, they would be parallel and there are no solutions between parallel lines.
