Write as a product: −y^3+xy^2−4x+4y
Semmy [17]

Answer:

(x-y)\left(y^{2}-4\right) \text { is the product of }-y^{3}+x y^{2}-4 x+4 y

Step-by-step explanation:

\text { Given equation is }-y^{3}+x y^{2}-4 x+4 y

\text { Writing all }^{a} x^{\prime \prime} \text { terms and "y" terms at a place. }

\left(-4 x+x y^{2}\right)+\left(4 y-y^{3}\right)

Now take “x” common in the first term and “y” common in second term then the equation becomes as follows:

x\left(-4+y^{2}\right)-y\left(-4+y^{2}\right)

x\left(y^{2}-4\right)-y\left(y^{2}-4\right)

(x-y)\left(y^{2}-4\right)

\text { The product of the given equation is }(x-y)\left(y^{2}-4\right)

A questionnaire asks shareholders of a company to state whether they consider the
Oduvanchick [21]

Using the binomial distribution, it is found that the probabilities are given as follows:

a) 0.5514 = 55.14%.

b) 0.3631 = 36.31%.

c) 0.4082 = 40.82%.

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

The formula is:

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

C_{n,x} = \frac{n!}{x!(n-x)!}

The parameters are:

  • x is the number of successes.
  • n is the number of trials.
  • p is the probability of a success on a single trial.

Item a:

In this problem, we have p = 0.82, n = 3, and the probability is P(X = 3), hence:

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 3) = C_{3,3}.(0.82)^{3}.(0.18)^{0} = 0.5514

Item b:

In this problem, we have p = 0.82, n = 3, and the probability is P(X = 2), hence:

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 2) = C_{3,2}.(0.82)^{2}.(0.18)^{1} = 0.3631

Item c:

We have to find P(X = 2) for the three probabilities, p = 0.82, p = 0.12, p = 0.05 and add them, hence:

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 2) = C_{3,2}.(0.82)^{2}.(0.18)^{1} = 0.3631

P(X = 2) = C_{3,2}.(0.12)^{2}.(0.88)^{1} = 0.0380

P(X = 2) = C_{3,2}.(0.05)^{2}.(0.95)^{1} = 0.0071

Then:

p = 0.3631 + 0.0380 + 0.0071 = 0.4082.

Fine the probability. NEED THE STEPS IF POSSIBLE.
Mekhanik [1.2K]

Answer:

The probability of getting an even number on a number cube is 1/2

The probability of getting the heads on a dime is 1/2

Step-by-step explanation:

A number cube has six numbers

And three of those numbers are even numbers.

Therefore;

Probability = 3/6

= 1/2

A dime has two faces, heads and tails

One of them is heads

Therefore;

Probability = 1/2
