Answer:
B, i might be wrong but i think its B
Answer:
Step-by-step explanation:
Let's start by factoring everything:
Now, you can cancel out some terms:
Now, when you divide a fraction by another fraction, that is the same as multiplying the first fraction by the reciprocal of the second one:
Hope this helps!
When I think about average with consecutive numbers, I think that it’s also the median. Let’s check.
If 12 is the median, there’s two numbers that are less than it and two that are more.
The list would be:
10, 11, 12, 13, 14
Let’s check to see if the average is 12. To find average, you have to add all the numbers together and then divide that number by the quantity of numbers in the list.
10+11+12+13+14=60
Now divide it by 5.
60/5=12
So, the largest number is 14.
Answer:
The probability that all 14 bits are 1s = 0.000061
Step-by-step explanation:
Probability that a bit is 1 is p = 0.5
Probability that a bit isn't 1 is q = 1 - 0.5 = 0.5
This is a binomial distribution problem
Binomial distribution function is represented by
P(X = x) = ⁿCₓ pˣ qⁿ⁻ˣ
n = total number of sample spaces = 14
x = Number of successes required = 14
p = probability of success = 0.5
q = probability of failure = 0.5
P(X = 14) = ¹⁴C₁₄ (0.5)¹⁴ (0.5)¹⁴⁻¹⁴
P(X = 14) = ¹⁴C₁₄ (0.5)¹⁴ (0.5)⁰
P(X = 14) = 1 (0.000061)(1) = 0.000061
