4:3 because there's 4 a's and 3 b's.
Answer:
The volume is 1386 cm³ and curved surface area is 396 cm².
Step-by-step explanation:
Given that,
The diameter of a cylinder is 14 cm
Height of the cylinder is 9 cm
We need to find the volume and curved surface area
.
If r is the radius, r = 14/2 = 7 cm
Volume of a cylinder is given by :

The curved surface area of the cylinder is given by :

So, the volume is 1386 cm³ and curved surface area is 396 cm².
Answer:
54º.
Step-by-step explanation:
two angles that are complementary have to add up to 90º. therefore, 90º-36º=54º angle.
Answer:
D
Step-by-step explanation:
D is on the same plane as A, B, and C
Answer: 0.9990
Step-by-step explanation:
Given : The number of bits in a string = 10
The value taken by a bit is either 0 or 1.
Therefore, the probability that the bit is zero = 
Binomial probability distribution formula :-
, where P(x) is the probability of getting success in x trials , n is the total number of success and p is the probability of getting success in each trial.
Now, the probability that you picked a string with at least one zero is given by :-

Hence, the probability that you picked a string with at least one zero = 0.9990
