Answer and Step-by-step explanation:

A random variable is a variable having numerical values determined by the outcomes of the experiment. A random variable may have a finite number or an infinite sequence of values said to be discrete.

A random variable that describes the number of automobiles sold at a dealership would be discrete one day. Simultaneously, a random variable represents the weight of a person in a kilogram or pounds.

The probability distribution of discrete random variable x is each possible value of x and the probability that x takes amount in one trial of the experiment.

The probability distribution of the random variable contains the following properties:

1- Each probability must be between 0 and 1.

0 ≤ p(x) ≤ 1

2- The sum of all probabilities is equal to 1.

Ʃp(x) = 1

A continuous random variable may assume any value from data. The continuous random variable takes costs that vary within one or more intervals. And it has a cumulative distribution function (CDF) that is absolutely continuous.

The random variable has an infinite number of possible values, which have zero probability. The range of this type of discount can have a nonzero chance.

The probability distribution of the random variable is described by probability density, where the probability can be calculated by taking the area under the curve.

Answer:

-1.973

Step-by-step explanation:

Given the data :

Age 36 39 48 53 58

Bone Density 358 351 330 325 314

Equation of regression line is in the form:

yˆ=b0+b1x

Where y = predicted variable ;

b0 = intercept ; b1 = slope or gradient ; x = predictor variable

Using The correlation Coefficient calculator :

The regression equation obtained is :

ŷ = -1.97316X + 427.94399

From the equation ;

The slope or gradient (b1) = - 1.97316

Hence, estimated slope to 3 decimal places is : - 1.973

Answer:

Because the law of contract has to do with private law relation.

Step-by-step explanation:

Given that law of contract has to deal with Private laws involving parties to the contract, but not in any way affecting or involving the state or society. The law of contract has seen so little constitutional transformation. For example law of the contract between manufacturers of cars and consumers or buyers.

This is evident in the fact that people's perception and the reality is that the outcomes of the successful delivery or breach of the law of contract have no direct implication on the other people in the society such as individual rights.

Answer:

neither; perpendicular; parallel; neither; neither

Step-by-step explanation:

parallel line is where the 2 slopes have same gradient and perpendicular means the two lines have a -1 slope when producted

This is a right angle triangle.

So, by Pythagoras theorem,

√(32^2+20^2) = x

or √(1024+400) = x

or √1424 = x

or 37.74 = x

Answer:

There will be 7 students on each bus.

Step-by-step explanation:

If the class of 63 students is divided into 9 buses with the same number of students traveling in each one, to determine the number of students traveling in each bus it is necessary to perform the following mathematical calculation:

63/9 = X

7 = X

Thus, in each bus 7 students will travel, and in this way all buses will carry the same number of students.

Answer:

9

12 to 26

Step-by-step explanation:

u go get that answer lol

Answer:

12 to 26

Step-by-step explanation:

First you have to identify the amount of red marbles (which is 12)

Then combine the total amount of marbles (including the red marbles)

Which should give you 12 to 26.

Answer:

20

Step-by-step explanation:

Answer:

x = -14/5 or -2.8

Step-by-step explanation:

6 - 5x = 20

Subtract 6 from both sides.

- 5x = 14

Divide both sides by - 5

x = -14/5 or -2.8

Answer:

Answer is 6 and 2/3. That’s it

Step-by-step explanation:

The length of JN of the second triangle is  [tex]6\frac{2}{3}[/tex].

If two triangles have an equal number of corresponding sides and an equal number of corresponding angles, then they are comparable.

Similar figures are described as items with the same shape but varying sizes, such as two or more figures.

As the two triangles BTL and PJN are similar because the corresponding two angles are given equal in the question.

Thus, the ratios of the side are equal.

[tex]\frac{BT}{JP} = \frac{LT}{JN}[/tex]

[tex]\frac{6}{8} =\frac{5}{JN}[/tex]

[tex]JN =\frac{20}{3}[/tex]

[tex]JN= 6\frac{2}{3}[/tex]

Therefore, the length JN of the triangle comes out to be [tex]6\frac{2}{3}[/tex].

Answer:

8 = 4 +$

Step-by-step explanation:

Like you said, we need to use substitution to solve for y.

[tex]x + y = 11\\-1(-x = -y - 9)\\\\x + y = 11\\x = y + 9\\\\y + 9 + y = 11\\\\2y + 9 = 11\\\\2y = 20\\\\y = 10[/tex]

Now that we've solved for y, we can plug in the number we got into one of the original equations. (You can choose either equation, but I will use the first one.)

[tex]x + 10 = 11\\\\x = 1[/tex]

Now we have the solution of this system.

Answer:

x = 24yrs and y = 27yrs

Step-by-step explanation:

Let the age of one of the teachers be x

Let the age of the other teacher be y

From the second sentence;

x + y = 51 ----------(1)

From the first sentence;

x/y = 8/9 ------------(2)

Making y the subject of formula in equation (1) as follows;

y = 51 -x -------------(3)

Substitute (3) into (2) as follows;

x/51- x = 8/9

Cross multiply as follows:

9*x = 8(51- x)

9x = 408 - 8x

Collecting like terms;

9x + 8x = 408

17x = 408

Divide both sides by 17;

x = 24 yrs

Substitute x = 24 into equation (3) as follows;

y = 51 - 24

y = 27 yrs

Answer:

(0.5, 1)

Step-by-step explanation:

The midpoint formula says that the midpoint between two points (a, b) and (c, d) is:

[tex](\frac{a+c}{2},\frac{b+d}{2})[/tex]

Here, a = -1, b = 5, c = 2, and d = -3, so the midpoint is:

[tex](\frac{a+c}{2},\frac{b+d}{2})[/tex]

[tex](\frac{-1+2}{2},\frac{5-3}{2})=(\frac{1}{2} ,\frac{2}{2} )=(0.5,1)[/tex]

The answer is thus (0.5, 1).

Answer:

10

Step-by-step explanation:

Miguel will circle 10 counters because 5/8 * 16 = 10.

Answer:

A. 10 is the correct answer.

Step-by-step explanation:

The equation is 5/8 x 16.

Here, there are 16 counters. This is also known as 2 rounds of 8, which is the denominator in our fraction. Since 8 is 1/2 times 16, 5 x 2, or 10, is the correct answer.
