The answer should be True. Only parallel lines do not cross, or intersect.
Answer:
a) 0.32
b) 0.68
c) office or den
Step-by-step explanation:
Locations Probabilities
Adult bedroom 0.03
Child bedroom 0.15
Other bedroom 0.14
Office or den 0.40
Other rooms 0.28
a)
P(PC in bedroom)= P(PC in adult bedroom)+ P(PC in child bedroom)+ P(PC in other bedroom)
P(PC in bedroom)= 0.03+0.15+ 0.14
P(PC in bedroom)= 0.32.
Thus, the probability that a PC is in a bedroom is 0.32.
b)
P(PC is not in bedroom)= P(PC in Office or den)+ P(PC in Other rooms)
P(PC is not in bedroom)= 0.40+0.28
P(PC is not in bedroom)= 0.68.
Thus, the probability that a PC is not in a bedroom is 0.68.
c)
When a household is selected at random from households with a PC we would expect to find a PC in a room which has a greater probability of having PC.
The greater probability of room having a PC is of Office or den room with probability 0.40. So, when a household is selected at random from households with a PC we would expect to find a PC in a Office or den room.
Answer with explanation:
Properties of Parallelogram
1. Opposite sides are equal and parallel.
2. Diagonals bisect each other.
3. opposite angles are equal.
We will use second property to find coordinates of Vertex P of this parallelogram.
Mid point formula,
The mid point of line segment joining two points, (a,b) and (c,d)=(x,y) is given by,
Let coordinates of P be (m,n).
So, Coordinates of vertex P of the parallelogram is (m,n)=(b+c-a,d) .
Option B
Answer:
To find the area of a trapezoid, multiply the sum of the bases (the parallel sides) by the height (the perpendicular distance between the bases), and then divide by 2.
