Answer with Step-by-step explanation:

For a given Binomial event with probability of success 'p' the probabolity of 'r' success in 'n' trails is given by

Thus for given 4 trails (n = 4) we have

Part 1)

Probability of 1 success is

Part 2)

Probability of 2 successes

Part 3)

Probability of at least 1 success

Step-by-step explanation:

chantal volunteered to bring 1 gallon of freshly squeezed orange juice to a picnic.the local grocery store sells 4-pound bags of

pochemuha

(128 oz) * (2 oranges)/(5 oz) * (1 bag)/(11.5 oranges) * $3.49/bag ≈ $15.54

Note that we have assumed 11.5 oranges per bag, and that partial bags are available.

If Chantal must buy whole bags of oranges, 5 bags will be needed and the cost will be $17.45.

Remark

You must use the sin law to find this.

$\dfrac{Sin(75)}{22} = \dfrac{Sin(x)}{12}$

Multiply through by 12

12 * $\dfrac{Sin(75)}{22} = \dfrac{Sin(x)}{12}$ *12

$\dfrac{12*sin(75)}{22} = \text{sin(x)}$

0.5269 = sin(x)

Now you have to use the inverse of the sine function.

Use your calculator for that

What are the possible rational roots of the polynomial equation?<br><br> 0=2x7+3x5−9x2+6

RoseWind [281]

Answer: $\pm\frac{1}{1}, \pm\frac{1}{2},\pm\frac{2}{1},\pm\frac{3}{1}, \pm\frac{3}{2}$

Step-by-step explanation:

We can use the Rational Root Test.

Given a polynomial in the form:

$a_nx^n +a_{n- 1}x^{n - 1} + … + a_1x^1 + a_0 = 0$

Where:

- The coefficients are integers.

- $a_n$ is the leading coeffcient ( $a_n\neq 0$ )

- $a_0$ is the constant term $a_0\neq 0$

Every rational root of the polynomial is in the form:

$\frac{p}{q}=\frac{\pm(factors\ of\ a_0)}{\pm(factors\ of\ a_n)}$

For the case of the given polynomial:

$2x^7+3x^5-9x^2+6=0$

We can observe that:

- Its constant term is 6, with factors 1, 2 and 3.

- Its leading coefficient is 2, with factors 1 and 2.

Then, by Rational Roots Test we get the possible rational roots of this polynomial:

$\frac{p}{q}=\frac{\pm(1,2,3,6)}{\pm(1,2)}=\pm\frac{1}{1}, \pm\frac{1}{2},\pm\frac{2}{1},\pm\frac{3}{1}, \pm\frac{3}{2}$

Mr.Hollis determines that he gives away $800 each month if he gives away 16% of his budget, how much is his overall budget

Fittoniya [83]

His budget is $5000

you take 800 and divide it by 0.16

gives you 5000
