Answer:
12 red cars
Step-by-step explanation:
15% is 0.15
So, you do 80 × 0.15, which is 12.
8/6 or 1 2/6 or 1 1/4
Explanation:
1/4 + 1/4 = 2/4
2/4 = 3/6
5/6 + 3/6 = 8/6
8/6 simplified is 1 2/6 or 1 1/4
To construct a triangle, the sum of any 2 sides of the triangle should be greater than the third side of the triangle.
lets calculate the sums of all the given choices to find out which three lengths given do not form a triangle.
A.
6,10,18
6 + 10 = 16
16 is smaller than the third side-18
Therefore these 3 lengths do not form a triangle
B.10,12,15
10 + 12 = 22 15+12 = 27 15 + 10 = 25
22>15 (3rd side) 27>10 (3rd side) 25>12 (3rd side)
In this triangle, sum of all the possible pairs of sides are greater than the third side therefore these lengths can form a triangle
C.10,15,6
10 + 15 = 25 15 + 6 = 21 10+6 = 16
25 > 6 21>10 16>15
in this too, sum of all the possible pairs of sides are greater than the third side. These lengths can be used to form a triangle
D.10,18 ,12
10 + 18 = 28 18 + 12 = 30 10 +12 = 22
28> 12 30>10 22> 18
Therefore these lengths can also be used to form a triangle
correct answer is 6,10 and 18 these cannot form a triangle
Answer:
0.853
Step-by-step explanation:
Use conditional probability. The probability of event A, given that event B has occurred, is:
P(A|B) = P(A and B) / P(B)
The probability that it is not raining, given that the flight leaves on time, is:
P(not raining | on time) = P(not raining AND on time) / P(on time)
P(not raining | on time) = 0.81 / (1 − 0.05)
P(not raining | on time) = 0.853
