This table shows the population of owls in a park in different years. The quadratic regression equation that models these data is
y = -1.34x2 + 10.75x - 11.3.

Using this model, the predicted number of owls in year 8 is about -11. Does
this prediction make sense? Why or why not?

answer: the anser is 3

step-by-step explanation:

c- 2o is equal to 9

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1

step-by-step explanation:

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !
