Binomial probability distributions depend on the number of trials n of a binomial experiment and the probability of success p on

FinnZ [79.3K]

The question is incomplete! Complete question along with answers and step by step explanation is provided below.

Question:

(a) Binomial probability distributions depend on the number of trials n of a binomial experiment and the probability of success p on each trial. Under what conditions is it appropriate to use a normal approximation to the binomial? (Select all that apply.)

nq > 10

np > 5

p > 0.5

np > 10

p < 0.5

nq > 5

(b) What is the probability of "12" or fewer successes for a binomial experiment with 20 trials. The probability of success on a single trial is 0.50. Use the normal approximation of the binomial distribution to answer this question. (Round your answer to four decimal places.)

Answer:

(a) The correct options are np > 5 and nq > 5

(b) P(x ≤ 12) = 0.8133

What describes this angle? Because I don’t know what the hell it means.

maw [93]

Answer:

Less than a right angle.

Step-by-step explanation:

If you really think about it, a right angle is 90 degrees, and from the looks of it, that angle shown is an acute angle. Acute angles are always smaller than a right angle, so your answer is less than a right angle. :)

If (-2, y) lles on the graph of y = 3^x, then y =

sweet [91]

<h3>Answer:</h3>

$\frac{1}{9}$

<h3>Step-by-step explanation:</h3>

We know that $x=-2$ , so substitute that into the equation. $y=3^{-2}$

With negative powers, instead of making the result negative, you divide one by it. Mathematically speaking, $x^{-y}=\frac{1}{x^y}$ . This makes our equation: $y=\frac{1}{3^2}$

Finally, simplify the exponent. $y=\frac{1}{9}$

How do i find the roots of this equation: f(x) = 2x5 - 9x4 + 12x3 - 12x2 + 10x - 3 = 0

Fantom [35]

The equation is <span>f(x) = 2x5 - 9x4 + 12x3 - 12x2 + 10x - 3 = 0
remark:
the sum of coefficients is = 2-9+12-12+10-3=-7+7=0, so a=1 is a zero of f
f can be written as </span>f(x) = (x-1)Q(x), and f(x) / (x-1)= Q(x)
after euclid's division
Q(x) = 2x4 - 7x3 + 5x2 - 7x +3
so for finding the other roots, making Q(x) for product of factors is a must
