Answer:
A. The r²-value of the linear model is greater than 0.977
Step-by-step explanation:
A P E X
A) HD Headphones. x=110 x=$70 ea
110×70=$7,700 for HD Headphones
10,000-7,700=2,300 left
y×w=2,300 for basic headphones
My guess, 230 basic headphones for $10 each
b) Basic headphones y×w
55×20=$1,100
2,000-1,100=900
HD Headphones
x×z=900
x=10,z=90 10×90=900
(I'm assuming that the price per item is higher due to the smaller quantity.
I don’t really know what the answer is
Answer: equation: y=-4x+1
slope: -4
y intercept:1
Answer:
(6, 7) and (-2, -1)
Step-by-step explanation:
if y=x+1 intersects with y=x^2-3x-11
then we need to find x and y such that both of those equations are true.
If y = x + 1 is true and y=x^2-3x-11, then
y - y = x^2-3x-11 - x - 1 is also true
0 = x^2 - 4x - 12
use your preferred method to solve the quadratic equation
0 = (x - 6)(x + 2)
x = 6 or x = -2
now for each x we take y from either equation, but y = x + 1 is simpler.
for x = 6 the coordinates are (6, 7) and for x = -2 the coordinates are (-2, -1)
