Answer: k=-3/2
Step-by-step explanation:
Y = 7x + 4
-4 from both sides
y - 4 = 7x
/ 7 on both sides
(y-4)/7 = x
Answer:
x = (y-4)/7
1) This probability is given by
... C(40,5)·0.12⁵·0.88³⁵ ≈ 0.18665 . . . . . where C(n, k) = n!/(k!(n-k)!)
2) This probability is given by
... 0.88⁴⁰ ≈ 0.00602
3) This is the complement of the probability that all have failed.
... 1 - 0.12⁴⁰ ≈ 1.0000
Answer:
x² +4x
Step-by-step explanation:
Area of triangle= ½ ×base ×height
Given: base= 2x, height= x +4
Area of triangle
= ½(2x)(x +4)
= x(x +4)
= x(x) +x(4) <em>(</em><em>expand)</em>
= x² +4x
Answer:
x is 71
Step-by-step explanation:
X + 72 + 37 = 180 ( Sum of angles in a triangle)
X = 180 - 72 - 37
X = 71
