Answer:

The probability mass function of X is:

[tex]p_{X}(x)={n\choose x}(p)^{x}(1-p)^{n-x};\ x=0,1,2,...n[/tex]

Step-by-step explanation:

A Binomial experiment has the following properties:

• There are a fixed number of trials (n).

• Each trial are independent of the others.

• Each trial has only two outcomes: Success and Failure

• Each trial has the same probability of success (p).

If a random variable X is used in an experiment and the experiment has all the above mentioned properties, then the random variable X is known as a binomial random variable.

Then the probability mass function of X is known as binomial probability distribution.

The probability mass function of X is:

[tex]p_{X}(x)={n\choose x}(p)^{x}(1-p)^{n-x};\ x=0,1,2,...n[/tex]

Answer:

x=39

Step-by-step explanation:

180-102=78

78/2=39

Answer:

x=39

Step-by-step explanation:

180-2x=102

-2x=-78

x=39

Answer:

x+2=12

x-1=11

10x=100

2x=20

Step-by-step explanation:

Answer:

x+2=12

x-1=11

10x=100

2x=20

Step-by-step explanation:

Answer:

Option (B)

Step-by-step explanation:

By exterior angle theorem,

Exterior angle of a triangle is equal to the sum of two opposite interior angles.

By the given theorem,

8x - 30 = (4x + 8) + (2x + 2)

8x - 30 = 6x + 10

8x - 6x = 40

2x = 40

x = 20

m∠BAC = (2x + 2) = (2×20) + 2

                              = 42°

Therefore, Option (B) will be the answer.

Answer:

no its not a function

Step-by-step explanation:

Answer:

It is not a 1 to one function

Answer:

C. Because it is 5 units to the left of 3 on a horizontal number line

Step-by-step explanation:

Directed numbers are numbers which has direction i.e either a negative or positive sign before it. This implies that all numbers are directed, since a number without a sign is taken to be positive.

Thus from the given expression,

3 + (-5) = 3 - 5

           = -2

So that,

3 + (-5) = -2

Expressing this on the number line, -2 is 5 units to the left of 3. Thus option C is appropriate.

Answer:

C has no slope

Step-by-step explanation:

Answer: The customer will make $80 as interest in 4 months.

Step-by-step explanation:

Given: Deposited amount : P = $4000

Rate of interest per year : r= 6% =0.06

Rate of interest monthly = [tex]\dfrac{r}{12}=\dfrac{0.06}{12}=0.005[/tex]

Time = 4 months

Simple interest = principal x rate of  interest x time

[tex]=4000\times 0.005\times 4=80[/tex]

hence, the customer will make $80 as interest in 4 months.

Answer:

2.66667 minutes

Step-by-step explanation:

2/3 of a minute is 40 so 40s times 4 equals 160s

Answer:

Anything with 2 Yellow and more than 3.5 Blue

Step-by-step explanation:

The answer is pretty obvious, but I will give a more mathimatical explanation that is easy to understand.  The ratio is saying that for every 2 units of yellow, there are 3.5 units of blue.  You can find ratios that are the same but use more/ less  amounts.  So if you use 4 units of yellow and 7 of blue it is the same ratio.  

If you multiply both parts of the ratio (or divide) by the same number you will always get the same ratio.  So if you want something more blue (or yellow) you just have to keep one the same while increasing the one you want to have more effect.  

Answer:

aint no way im answering all of those

kid just put them in y=mx+b form by isolating the y

Step-by-step explanation:

i'll do #19 for ya

y-4 = 3(x-2)

3(x-2) turns into 3x-6 when u distribute it

y-4 = 3x-6

isolate the y by adding 4 on both sides

y=3x-2

there ~ it's in slope intercept form

Answer:

19. Y = 3x - 2

20. Y = -x - 6

21. Y = -2x + 2

22. Y = -5x + 14

23. Y = 6x - 3

24. Y = 3x + 23

25. Y = 1/2x + 5

26. Y = 1/3x + 2

27. Y = x + 1

Answer:

93

Step-by-step explanation:

add 56+31 which give you 87

subtract 87 from 180 (180-87)

and you get 93 for x

Answer:

93

Step-by-step explanation:

56+31=87

180-87=93

Answer:

1 is the correct answer

Answer:

157.62

Step-by-step explanation:

I took the mass(g) of 34.932 and divided it by the volume of 4.1

[tex]\frac{34.932}{4.1} =8.52[/tex]

To prove that this was correct I did the same thing for the next row

[tex]\frac{47.712}{5.6} =8.52[/tex]

I took 8.52 and multiplied it by the volume of 18.5 to get the mass.

[tex]8.52*18.5=157.62[/tex]

The mass is 157.62

hope this helps! :))

Step-by-step explanation:

g lpreeeeeeeee3eeeere

Step-by-step explanation:

X+106=180 [(being cointerial angle]

or, X=180-106

or,X=74

therefore,X=74

2y=X=74[being corresponding angle]

X+(4z+6)=180[being exterior cointerior angle]

or, 74+6+4z=180

or,4z=180-80

or,4z=100

or,z=100/4

or,z=25

Answer:

60

Step-by-step explanation:

This shape can be divided into a rectangle and a right triangle.

rectangle: l x w = 8 x 6 = 48

triangle: .5bh = .5 x (12-8) x 6 = 12

48 + 12 = 60 square units

hope this helped!

Answer:

x = -2 :)

Step-by-step explanation:

5x - 3 = 2x - 9

3x = -6

-6/3 = -2

Answer:

x = -2

Step-by-step explanation:

I dunno which one to answer so I'll do both. (the question you posted or the picture??)

5x - 32x - 9

First we can combine the like terms 5x and -32x. Which is -27x

We can't combine -9 with anything so it stays the same.

-27x - 9

________________________________

5x - 3 = 2x - 9

-2x        -2x      

3x - 3 = -9

Here I subtracted -2 from both sides.

3x - 3 = -9

    +3    +3

3x = -6

Divide both sides by 3 to isolate the variable.

x = -2

(sorry this is so long) Hope this helps and have a great day!
