Answer: 0.20
Step-by-step explanation:
The given probability distribution of number of televisions per household in a small town:
x 0 1 2 3
P(x) 0.05 0.15 0.25 0.55
To find : The probability of randomly selecting a household that has one or two televisions ( in both parts a. and b.).
The computations for this would be :
P( 1 or 2) = P(1)+P(2)
= 0.05+0.15
= 0.20
Hence, the required probability= 0.20

Answer:
B. Scalene and D. Acute
Step-by-step explanation:
Check each answer.
A. Equilateral
All sides or all angles are not equal. So it is not equilateral.
B. Scalene
All sides are unequal. So it is scalene.
C. Obtuse
No any angle is greater than 90°. So it is not obtuse.
D. Acute.
All angles are less than 90°. So it is acute.
E. Isosceles
No two sides are equal. So it is not isosceles.
F. Right
No angle is 90°. So it is not right
Therefore, only answers B. Scalene and D. Acute are correct.

Answer:
The the length of the road between city 'c' and city 'a' could be miles.
Step-by-step explanation:
Consider the attached figure a.
As
- the city 'a' and city b are connected by a 20 mile road, as shown in attached figure a.
and
- the city 'b' and city c are connected by a 6 mile road, as shown in attached figure a.
As the connection between a, b, and c makes a right triangle as shown in figure a.
So, the length of the road between city c and city a can be computed using Pythagorean theorem.
≈ miles
So, the the length of the road between city 'c' and city 'a' could be miles.
