Forgive me if this is wrong. I haven't done stat in a year, but comment if you need clarification!
Answer:
18
Step-by-step explanation:
bc 8 digits in the ones place, and less than 21 greater than 15
A. from 67.86 all the way to the end. (67.86 is not filled)
b. $67.86,
$80.00,
$70.00(values equal to or greater than $67.86.)
c. There are many values that represent this inequality.(values equal to or greater than $67.86)
Hope this helped☺☺
y = -
x + 
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
y = 4x + 5 is in this form with slope m - 4
Given the slope of a line m, then the slope (
) of a line perpendicular to it is
= - (1 / m ) = - 
y = -
x + c is the partial equation of the perpendicular line
to find c, substitute ( 2, 7 ) into the partial equation
7 = -
+ c ⇒ c = 
y = -
x +
← equation of perp. line
