X-4=-11
move -4 to the other side
to get X by itself
sign changes from -4 to +4
X-4+4= -11+4
X= -11+4
Answer:
X= -7
Answer:No
Step-by-step explanation:
The volume of a rectangular prism can be found by the formula:
V = A × h
Where:
A = area of the base of the prism
h = height of the prism
Therefore:
V = 450 × 53
= 23850 in³
The volume of the file cabinet is <span>23850 in³.</span>
∑x = 1 + 2 + 3 + 4 + 5 + 6 = 21
∑y = 8 + 3 + 0 + 1 + 2 + 1 = 15
∑x^2 = 1 + 4 + 9 + 16 + 25 + 36 = 91
∑y^2 = 64 + 9 + 0 + 1 + 4 + 1 = 79
∑xy = 8 + 6 + 0 + 4 + 10 + 6 = 34
r
= (n∑xy - ∑x∑y)/(sqrt(n∑x^2 - (∑x)^2)*sqrt(n∑y^2 - (∑y)^2)) = (6(34) -
21(15))/(sqrt(6(91) - (21)^2)*sqrt(6(79) - (15)^2)) = (204 -
315)/(sqrt(546 - 441)*sqrt(474 - 225)) = -111/(sqrt(105)*sqrt(249)) =
-111/(10.25*15.78) = -111/161.7 = -0.68
