Assume the random variable X has a binomial distribution with the given probability of obtaining a success. Find the following p

The required probability of success is given by 0.98906500

Assume the random variable X has a binomial distribution with the given probability of obtaining a success.
P(X<5), n=6, p=0.3

<h3>What is binomial distribution?</h3>

In binomial distribution for number trials we are investigating the probability of getting a success remain the same.

n = number of trails,
p = probability of success
x = the number of success

p(x<5) = P(x=0)+ p(x=1) + p(x=2)+p(x=3)+p(x=4)

= $\binom{6}{0}(0.3)^0(1-0.3)^6+\binom{6}{1}(0.3)^1(1-0.3)^5+\binom{6}{2}(0.3)^2(1-0.3)^4+\binom{6}{3}(0.3)^3(1-0.3)^3+\binom{6}{4}(0.3)^4(1-0.3)^2$

p(x<5) = 0.98906500

Thus the required probability of success is given by 0.98906500

If possible, choose k so that the following function is continuous on any interval:

Alexxx [7]

We need to cancel out the discontinuity in x = 4

In order to do that, factorize the numerator:
5x⁴ - 20x³ = 5x³(x-4)

This way, your function will be:
f(x) = <span>5x³(x-4) / (x-4)

and the two parentheses cancel out, leaving
</span>f(x) = <span>5x³
</span>
which at x = 4 gives:
f(4) = <span>5·4³</span> = 5 · 64 = 320

Therefore K = 320.

Answer:

C. 19

Step-by-step explanation:

$f(x) = x {}^{2} + 3x + 1 \\ f(3) = 3 {}^{2} + 3(3) + 1 \\ = 19$
