Example 2: gas mileage and the normal distribution
a normal curve is a smooth curve that is symmetric and bell shaped. data distributions that are mound shaped are often modeled using a normal curve, and we say that such a
distribution is approximately normal. one example of a distribution that is approximately normal is the distribution of compy heights from example 1. distributions that are approximately
normal occur in many different settings. for example, a salesman kept track of the gas mileage for his car
over a 25-week span.
the mileages (miles per gallon rounded to the nearest whole number) were
23, 27, 27, 28, 25, 26, 25, 29, 26, 27, 24, 26, 26, 24, 27, 25, 28, 25, 26, 25, 29, 26, 27, 24, 26.

answer is x<

its a straight line parallel to the time axis

include a picture of the drawing in order for me to

step-by-step explanation:

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
