AC = 4.6

Step-by-step explanation:

since AX and XC are equal amd XC= 2.3

so AC = 2*2.3

Step-by-step explanation:

Answer:

x=6

y=3

Step-by-step explanation:

y(side)= x

x(side)=2x

3rd side (3[tex]\sqrt{3}[/tex]) = x[tex]\sqrt{3}[/tex]

x=3;

x= 2(3)=6

y=(3)=3

Answer:

x = 6 ; y = 3

Step-by-step explanation:

x = 2y

4y² = y² + 27

3y² = 27

y² = 9

y = 3 and x = 6

Answer:

μ₁`= 1/6

μ₂=  5/36

Step-by-step explanation:

The rolling of a fair die is described by the binomial distribution, as  the

The moment generating function of the binomial distribution is derived as below

M₀(t) = E (e^tx)

        = ∑ (e^tx) (nCx)pˣ (q^n-x)

        = ∑ (e^tx) (nCx)(pe^t)ˣ (q^n-x)

        = (q+pe^t)^n

the expansion of the binomial is purely algebraic and needs not to be interpreted in terms of probabilities.

We get the moments by differentiating the M₀(t) once, twice with respect to t and putting t= 0

μ₁`= E (x) = [ d/dt (q+pe^t)^n]  t= 0

            = np

μ₂`=  E (x)² =[ d²/dt² (q+pe^t)^n]  t= 0

              = np +n(n-1)p²

μ₂=μ₂`-μ₁` =npq

in similar way the higher moments are obtained.

μ₁`=1(1/6)= 1/6

μ₂= 1(1/6)5/6

   = 5/36

Answer:

The AP is 6, 11, 16, 21, 26, 31, 36, 41, 46, 51, 56, 61 ....

Step-by-step explanation:

The nth term = a1 + d(n - 1)

Sum of 5th and 9th terms

= a1 + 4d + a1 + 8d = 72

2a1 + 12d = 72.............(1)

Similarly:

a1 + 6d + a1 + 11d = 97

2a1 + 17d = 97..............(2)

Subtracting equation (1) from equation (2):

5d = 25

d = 5.

and , using equation (1), the first term

a1 = (72 - 12(5)) / 2

= 12/2

= 6.

Answer:

The figure is translating right 5 and down 6

Step-by-step explanation:

X and Y both represent axis on a coordinate grid. x+5 simply means adding 5 to a value. In other words, on a coordinate grid, an increase in the value means you are going right, the lower the farther left. Same for the y axis, the higher the more you are increasing vertically, the lower the value the lower the point is.

The answer for height is 20

Step-by-step explanation:

Answer:

Step-by-step explanation:

Use the half life formula

[tex]N=N_0e^{kt}[/tex] where N is the amount after decay, No is the initial amount, e is Euler's number, k is the decay constant, and t is the time in minutes. For us, the first equation looks like this:

[tex]7=12e^{k(70)}[/tex] and we will solve that for k and then use that value of k in the second equation to find time.

Begin by dividing 7 by 12 to get

[tex]\frac{7}{12}=e^{k(70)}[/tex] Now take the natural log of both sides since the natural log and that e are inverses. The e then disappears:

[tex]ln(\frac{7}{12})=k(70)[/tex]

Plug the left side into your calculator and then set it equal to the right side, giving us:

[tex]-.5389965007=70k[/tex]

Divide both sides by 70 to get the k value of

k = -.00769995

Now the second equation looks like this:

[tex]2=12e^{(-.00769995)t[/tex] where t is our only unknown now that we know k.

Begin by dividing both sides by 12 to get

[tex]\frac{1}{6}=e^{-.00769995t[/tex] and take the natural log of both sides again to eliminate the e:

[tex]ln(\frac{1}{6})=-.00769995t[/tex]

Take care of the left side on your calculator to get

-1.791759469 = -.00769995t and divide both sides by -.00769995 to get

t = 232.697 minutes
