Answer:

Step-by-step explanation:

From the given information, it is likely that the random variable(X) have the values below:

Let head be H

Let tail be T

So;

X(HH) = 2;

X(HT) = 1;

X(TH) = 1;

X(TT) = 0

The distribution can now be computed as:

[tex]p(X= TT) = \dfrac{1}{4}[/tex]

[tex]p(X=TH) = \dfrac{1}{4}[/tex]

[tex]p(X=HT) = \dfrac{1}{4}[/tex]

[tex]p(X=HH)= \dfrac{1}{4}[/tex]

Now, the expected value that is equivalent to the number of heads when the coin is flipped twice is:

[tex]E(X) = p(TT)*X(TT)+p(TH)*X(TH)+p(HT)*X(HT)+p(HH)*X(HH)[/tex]

[tex]E(X) = \dfrac{1}{4}\times 0 + \dfrac{1}{4}\times 1 + \dfrac{1}{4}\times 1 + \dfrac{1}{4}\times 2[/tex]

[tex]E(X) = 0 + \dfrac{1}{4}+ \dfrac{1}{4} + \dfrac{1}{2}[/tex]

[tex]E(X) =\dfrac{1+1+2}{4}[/tex]

[tex]E(X) =\dfrac{4}{4}[/tex]

E(X) = 1

[tex]E(X^2) = p(TT)*X(TT)^2+p(TH)*X(TH)^2+p(HT)*X(HT)^2+p(HH)*X(HH)^2[/tex]

[tex]E(X^2) = \dfrac{1}{4}\times 0^2+ \dfrac{1}{4}\times 1^2 + \dfrac{1}{4}\times 1^2 + \dfrac{1}{4}\times 2^2[/tex]

[tex]E(X^2) = 0 + \dfrac{1}{4}+ \dfrac{1}{4} + \dfrac{4}{4}[/tex]

[tex]E(X^2) =\dfrac{1+1+4}{4}[/tex]

[tex]E(X^2) =\dfrac{6}{4}[/tex]

[tex]E(X^2) =1.5[/tex]

Finally; To compute E²[X]

E²[X] = E[X]²

E²[X] = 1²

E²[X] = 1

Step-by-step explanation:

You need to multiply the row and column to get the numbers

for example the block with row 3 column 3,the answer is 3 x 3= 9

each spinner can land on any of the points it has, thus each of the number have the same possibility.

Answer:

wsfgnjjjj3999878 ixixixisixiixxiix

Answer: they are not equivalent be 3(6x+1) is 18x+3 and 21x stays the same so there for they are not equivalent to each other

Step-by-step explanation:

Answer:

Dependent

Step-by-step explanation:

The first draw has 10 marbles, the second draw has 9 marbles and the color of those 9 marbles depends on the marble picked in the first draw so the events are dependent.

Answer:

Dependant

Step-by-step explanation:

It would be independent if you put the marble BACK, because at first it was 1/10 to get the white marble and then it became 1/9.

The difference between twelve and three times a number.

Answer:

option C. n = 24

Step-by-step explanation:

n - 21 = 3

n - 21 + 21 =  3 + 21                [adding 21 on both sides ]

n + 0 = 24                              [ -21 + 21 = 0 ]

n = 24

Answer:

23 marbles

Step-by-step explanation:

Answer:

[tex]f(x) = 0.80x[/tex]

Step-by-step explanation:

Given

[tex]x \to price[/tex]

[tex]discount \to 20\%[/tex]

[tex]coupon = \$50[/tex]

Required

The function f(x) if only the discount applies

20% discount implies that the price will be reduced by 20%.

So, the function is:

[tex]f(x) = Price - Price * Discount[/tex]

[tex]f(x) = x - x * 20\%[/tex]

Factorize

[tex]f(x) = x(1 - 20\%)[/tex]

Express percentage as decimal

[tex]f(x) = x(1 - 0.20)[/tex]

[tex]f(x) = x(0.80)[/tex]

[tex]f(x) = 0.80x[/tex]

Answer:

60%

Step-by-step explanation:

[tex]percentage = \frac{24}{40} \times 100\% \\ = 60\%[/tex]

[tex]\Huge{\textbf{\textsf{{\purple{Ans}}{\pink{wer}}{\color{pink}{:}}}}} \\ [/tex]

[tex]percentage = \frac{24}{40} \times 100\% \\ = 60\%[/tex]

so answer is 60%

Answer:

£2348.48

Step-by-step explanation:

We can use the “slow method” for this, seeing it’s only 3 years.

£2000 * 105.5% = 2110 * 105.5% = 2226.05 * 105.5% = 2348.48

(105.5% = 1.055, by the way)

After the initial calculation, you can use Ans * 1.055 until you’ve hit the three years.

Answer:

Answer:

  x ≈ 13.7

Step-by-step explanation:

The relevant trig relation is ...

  Tan = Opposite/Adjacent

  tan(58°) = 22/x

  x = 22/tan(58°) ≈ 13.747

The value of x is about 13.7 units.

Answer:

Step-by-step explanation:

It's -3

Answer:

c. -x + 3x + 7  = 2x+7

Step-by-step explanation:

f(x) = 3x +1 and g(x) = x - 6

f-g = 3x +1 - ( x - 6)

Distribute the minus sign

     = 3x+1 - x+6

     = 2x +7

The answer would be 30 because the triangle is 10, the circle is 5, and each black triangle is 2 which would be 10 plus 5 which is 15 then times 2 which is 30.

Answer:

20?

Step-by-step explanation:

If 3 triangles = 30 they we could assume that each triangle = 10

10 + 10 + 10 = 30

If one triangle = 10 then the 2 circles would = 5 in the 2nd equation

10 + 5 + 5 = 20

If 1 circle = 5 then the 1 full squares would = 4

5 + 4 + 4 = 13

1 triangle = 10 , 1 circle = 5, Half a square = 2

10 + 5 * 2 = ?

Using PEMDAS we would multiply 2 and 5 first to get 10

10 + 10 = 20

Answer: 0.2

Step-by-step explanation:

1 divided by 5 = 0.2

Answer:

Step-by-step explanation:

1/5 = 1 divided by 5.

This will also apply to any fraction

Fraction = Numerator divided by Denominator

========================================================

Explanation:

Let's replace n with 9 to see if we get a true inequality or not.

2n > 16

2*9 > 16

18 > 16

We get a true statement since 18 is indeed larger than 16. Therefore, n = 9 is a solution.

------------

Here's another way to tackle the problem:

We can isolate n as if solving an equation. Divide both sides by 2 to do this. The inequality sign does not flip (it only does so if you divide both sides by a negative number).

So we get...

2n > 16

2n/2 > 16/2

n > 8

The solution set is any number larger than 8. Since n = 9 fits the description, that's one of the infinitely many solutions.

------------

Side note: The graph will involve an open hole at 8 and shading to the right on the number line.

Answer:

b = 34°

Step-by-step explanation:

b + 115° + 31° = 180°

b + 146° = 180

b = 180° - 146°

b = 34°

Answer:

[tex] {b}^{o} = {34}^{o} [/tex]

Step-by-step explanation:

Hint :

Sum of angles = 180°

Simplify :

[tex] {115}^{o} + {31}^{o} + {b}^{o} = {180}^{o} [/tex]

[tex] {146}^{o} + {b}^{o} = {180}^{o} [/tex]

[tex] {b}^{o} = {180}^{o} - {146}^{o} [/tex]

[tex] {b}^{o} = {34}^{o} [/tex]

Answer:

3

Step-by-step explanation:

you can set up a ratio using corresponding parts from each triangle.
