Answer:
not sure but this should be it
Answer:
0.046145 = 4.6145%
Step-by-step explanation:
We need to find the probability of 19 or 20 (all) students considering calculus to be an exciting subject, so first we find the probability for 19 students, then for 20 students, and we sum these probabilities.
The probability of the student NOT considering calculus to be an exciting subject is 1 - 0.78 = 0.22
For 19 students, we also have to calculate a combination of 20 choose 19, as these 19 students can be in different "position" among the 20 students, so:
C(20,19) = 20!/19! = 20
Probability of 19 students considering calculus to be an exciting subject:
C(20,19) * 0.78^19 * 0.22^1 = 0.039196756
Probability of 20 students considering calculus to be an exciting subject:
C(20,20) * 0.78^20 = 1 * 0.78^20 = 0.006948516
The final probability is:
0.039196756 + 0.006948516 = 0.046145272 = 4.6145272%
Rounding to six decimal places: 0.046145 = 4.6145%
Answer:
14
Step-by-step explanation:
The least common multiple is a number that both numbers can multiply something to get to, and the smallest possible common one.
Let's try listing out the multiples of 2:
2, 4, 6, 8, 10, 12, 14, 16, 18, 20
And the multiples of 7:
7, 14, 21, 28, 35, 42, 49, 56, 63, 70
Notice that both have the number 14 in common, and it is the first number that they do so. There are lots of other multiples that they have in common too, but 14 is the least.
We have been given that :-
The length of a parasite in experiment A is 
The length of a parasite in experiment B is 
Let us write the the length of the parasite in experiment A in the exponent of -3.
Clearly, the length of parasite in experiment A is greater than the length of parasite in experiment B.
The difference in the length is given by
Therefore, the length of the parasite in experiment A is inches greater than the length of the parasite in experiment B.
