Answer:

The binomial probability formula can not be used for this experiment because it does not state the number of times he expects to draw his favorite suit.  

Step-by-step explanation:

The binomial probability formula is expressed as follows:

P (k success in n trials) = \left \{ {{n \atop k} \right. p^{k}q^{n-k}

n = number of trials, k = number of successes, n-k = number of failures, p = probability of success in one trial and q = 1 - p = probability of failure in one trial.  

In the given problem, all of the variables are known except for 'k', the amount of times that the student predicts he will draw his favorite suit.

Find the surface area of the following figure with the given dimension
andrezito [222]

Answer:

The surface area is 54 square feet

Step-by-step explanation:

Given

The attached figure

Required

The surface area

This is calculated as:

SA = 2(LW + LH + HW)

Where

L = Length\\ W = Width\\ H = Height\\

So,

SA = 2  * (3 * 3 + 3 * 3 + 3 * 3)

SA = 54

18) The degree of P(x) = (x-1)(x+2)(x+3)(2x-5) is<br><br><br>4<br>3<br>2<br>1​
Fantom [35]

Answer:

degree 4

Step-by-step explanation:

The degree of a polynomial is determined by the term with the largest exponent for the polynomial in standard form

Given

P(x) = (x - 1)(x + 2)(x + 3)(2x - 5)

We need only consider the product of the leading terms in each factor, that is

x(x)(x)(2x) = 2x^{4} ← is the leading term in the expansion of the factors

with exponent 4

Thus polynomial is of degree 4
