Answer:
It is split open, therefore creating a new polygon
Step-by-step explanation:
Given:
Population mean, μ = 10
Population standard deviation, σ = 1.5
Random variable, x = 11.
By definition, the z-score is
z = (x - μ)/σ
= (11 - 10)/1.5
= 0.667
Answer: 0.667
8x-10y=-23
9x+10y=-16
(8x+9x)+(10y-10y)=(-23+(-16))
17x+0y=-39
x=-39/17
8(-39/17)-10y=-23
-312/17-10y=-23
-10y=-23+312/17
-10y=-79/17
y=79/170
Choice D, perpendicular is when the slopes are inverted to each other such as 1/2 and -2/1
Answer:
1. (q² + 8) - (4q² + 1)
Simplify each term.
q²+8−4q²−1
Simplify by adding terms.
−3q²+7
2. (3x + 7x² - 6) - (5x² + x + 9)
Simplify each term.
