The answer to this question is C
The cube root of 287496 is 66
Answer:
4. -2s^9
7. 8b^10
Step-by-step explanation:
First, focus on the number part of the expression. For 4), multiply -2 x -1 x -1 = -2. Then, look at the exponents. When you're multiplying exponents with the same base (in number 4, the base is s), you can add the exponents.
2+3+4 = 9; which makes it s^9. Multiply -2 x s^9, which gives you -2s^9.
Same thing for 7). Multiply all the numbers first. this gives you 8. (Remember two negatives equals a positive). Add all of the exponents of b together, which gives you 10. (when a variable has no exponent, it means that the exponent is 1.) Multiplying 8 and b^10 should give you 8b^10.
It may help to brush up on exponent rules and sign rules.

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
