Answer:

The correct option is;

Step-by-step explanation:

By the representation of numbers in a figurative for, we have;

1) Th rational numbers that can be expressed in the form a/b, where a and b are real numbers

2) The integers are the direct subset of the set of rational numbers and are displayed in he next larger ellipse in the figure

3) The whole numbers are the direct subset of the set of integers.

A scientist is working with 1.3m of gold wire. How long is the wire in millimeters

CaHeK987 [17]

Answer:

1300 mm

Step-by-step explanation:

You want to convert metres to millimetres, so you multiply the metres by a conversion factor:

1.3 m × conversion factor = x mm

1 m = 1000 mm.

So, the conversion factor is either (1 m/1000 mm) or (1000 mm/1 m).

We choose the latter, because it has the desired units on top.

The calculation becomes

$\text{Length} = \text{1.3 m} \times \dfrac{\text{1000 mm}}{\text{1 m}} = \textbf{1300 mm}$

If N = , r = , and n = , and assuming that X has a hypergeometric probability distribution, compute the following. Write your an

artcher [175]

Answer:

(a) The value of P (X = 2) is 0.3571.

(b) The value of P (X ≤ 1) is 0.5952.

Step-by-step explanation:

A Hypergeometric distribution is used to describe the probability distribution of x successes in n random draws from a population of size N that contains exactly r items that are considered as success. In this distribution each draw results in either a success or a failure.

The probability mass function of Hypergeometric distribution is:

$P(X=x)=\frac{{r\choose x}{N-r\choose n-x}}{{N\choose n}}$

Given:

N = 9

r = 3

n = 4

(a)

Compute the value of P (X = 2) as follows:

$P(X=2)=\frac{{3\choose 2}{9-3\choose 4-2}}{{9\choose 4}}=\frac{3\times 15}{126}=0.3571$

Thus, the value of P (X = 2) is 0.3571.

(b)

Compute the value of P (X ≤ 1) as follows:

P (X ≤ 1) = P (X = 0) + P (X = 1)

$=\frac{{3\choose 0}{9-3\choose 4-0}}{{9\choose 4}}+\frac{{3\choose 1}{9-3\choose 4-1}}{{9\choose 4}}\\=0.1190+0.4762\\=0.5952$

Thus, the value of P (X ≤ 1) is 0.5952.

Solve for the measure of a

Lena [83]

Answer:

Step-by-step explanation:

The supplement of the exterior angle is 180 - 75 = 105

In a cyclic quadrilateral (a four sides figure where all the vertices touch the circumference of a circle), the opposite angles are supplementary. Therefore <a = 180 - 105 = 75

But I think you already knew that.
