Answer:
Probability of at least two cuckoo eggs is 0.738.
Step-by-step explanation:
probability of cuckoo egg = 0.1
probability of not a cuckoo egg = 1 - 0.1 = 0.9
Probability of at least two cuckoo eggs is
= Probability of two cuckoo eggs x probability of 1 not cuckoo egg +
probability of three cuckoo eggs
= 0.1 x 0.1 x 0.9 + 0.9 x 0.9 x 0.9
= 0.009 + 0.729
= 0.738
Width: x
Length: 2x
Perimeter=2x+2x+x+x=6x
32 cm more than width means x+32
6x=x+32
5x=32
x=6.4
Dimension is 6.4×12.8 (width×length)
Perpendicular means that it has a slope that is the reciprocal of the original, and parallel means that the slopes are the same.
Answer: divide the big number by 2
Step-by-step explanation: dude it literally tells you the answer almost xD jsut divide the big number by 2
Answer:
5x-18=4x+7 ( vertical opposite angle)
5x-4x=7+18
x=25
