Out of six computer chips, two are defective. If two chips are randomly chosen for testing (without replacement), compute the pr
Ratling [72]

Answer:

The probability that of the two chips selected both are defective is 0.1089.

Step-by-step explanation:

Let <em>X</em> = number of defective chips.

It is provided that there are 2 defective chips among 6 chips.

The probability of selecting a defective chip is:

P(X)=p=\frac{2}{6}=0.33

A sample of <em>n</em> = 2 chips are selected.

The random variable <em>X</em> follows a Binomial distribution with parameter <em>n</em> = 2 and <em>p</em> = 0.33.

The probability function of a Binomial distribution is:

P(X=x)={n\choose x}p^{x}(1-p)^{n-x};\ x=0, 1, 2, ...

Compute the probability that of the two chips selected both are defective as follows:

P(X=2)={2\choose 2}(0.33)^{2}(1-0.33)^{2-2}=1\times 0.1089\times 1=0.1089

Thus, the probability that of the two chips selected both are defective is 0.1089.

The sample space of selecting two chips is:

S = (1, 2), (1, 3), (1, 4), (1, 5), (1, 6)

     (2, 1),  (2, 3), (2, 4), (2, 5), (2, 6)

     (3, 1), (3, 2), (3, 4), (3, 5), (3, 6)

     (4, 1), (4, 2), (4, 3), (4, 5), (4, 6)

     (5, 1), (5, 2), (5, 3), (5, 4), (5, 6)

     (6, 1), (6, 2), (6, 3), (6, 4), (6, 5)

On the basis of the graph, answers the following questions.
Pepsi [2]

a) The factors have the form:

(x-x_1)

where x1 is a zero of the function. A zero is a point at which the graph intercepts the x-axis. From the graph, the zeros are:

-6, -4, 2, and 3

Therefore, the factors are:

(x + 6)

(x + 4)

(x - 2)

(x - 3)

b) Multiplying all these factors we get a polynomial, p(x), with the zeros of the graph. That is:

p(x) = (x + 6)(x + 4)(x - 2)(x - 3)

c) Yes, it is possible to find other polynomials with the same zeros. To do that we have to multiply p(x) by a constant. For example, multiplying by 2:

f(x) = 2(x + 6)(x + 4)(x - 2)(x - 3)

and f(x) has the same zeros as p(x)

d) Every polynomial obtained in the previous way, multiplying p(x) by a constant, will have a different graph. In conclusion, it is not possible to find other polynomials with the same zeros and the same graph.

What is the answer to this fraction ?
sammy [17]

Answer:

7 3/12 simplified 7 1/4

Step-by-step explanation:

first make 1/3 into the same denominator as 7/12

so 3 and 12 both have 4 in common so

4 times 1/3 = 4/12

then just subtract

and you would get 7 3/12 which could be simplified to 7 1/4

Which formula can be used to find the nth term of a geometric sequence where the fifth term isn1/16 and the common ratio is 1/4?
kati45 [8]

1/16=a(1/4)^(5-1)

1/16=a(1/4)^4

1/16=a/256

256/16=a

16=a

So the initial term is 16 so our formula is:

a(n)=16(1/4)^(n-1)
