The way to do this question is : difference of the two sides < x < sum of the two sides. so for 1) 4 < x< 8
2) 8 < x< 16
3) 9 < x < 13
i’m pretty sure this is right! hope it helps!
Answer:
<em> x = -3</em>
Step-by-step explanation:
A line has equation: y = ax + b
This line has slope a = 1
This line passes (4, 1)
=> 1 = 4 + b
=> b = -3
=> The equation of this line : y = x - 3
This line passes another point (x, -6)
=> -6 = x - 3
=> x = -6 + 3
=> x = -3
Answer:
9
Step-by-step explanation:
36 ÷ 4 = 9
36 ÷ 9 = 4
<span>Answer: Skewed to right with mean 0 and S.D. 1
Explanation: Let's assume the z-scores as a linear transformation.
then z=(x-mean)/S.D. = (x-30)/15
z(mean) = (30-30)/15= 0
z(sigma) = 15/15 = 1
