This is a binomial distribution.
p = 0.71, q = 1 - p = 1 - 0.71 = 0.29, n = 20
P(x ≤ 19) =1 - P(x = 20) = 1- 20C20 x (0.71)^(20 - 20) x (0.29)^20 = 1 - 0.29^20 = 1 - 0 = 1

A parallelogram is a flat shape with opposite sides parallel and equal in length. The diagonals of a parallelogram bisect<span> each other. In simpler words, they intersect halfway point. We calculate as follows:
</span>d2 = √<span>2a^2 + 2b^2 - d1^<span>2
</span></span>d2 = √2(7)^2 + 2(9)^2 - 14^2
d2 = 8 inches
Answer:
t = 41.6 (the 6 is repeating)
Step-by-step explanation:
2.5t + 350 = 3t + 225
Subtract 2.5t from both sides to get:
350 = 3t + 225
Now subtract 225 from both sides to get:
125 = 3t
Divide both sides by three.
t = 41.6 (the 6 is repeating)
