Write the values in the boxes that make the statement true

nikklg [1K]

Answer:

$\frac{5}{3}xz^8*9x^6y^0z^2 = 15x^7z^{10}$

Step-by-step explanation:

Given

$\frac{5}{3}xz^a*bx^cy^dz^2 = 15x^7z^{10}$

Simplify

$\frac{5}{3}b*x^{1+c}z^{a+2}y^d = 15x^7z^{10}y^0$

Compare left and right sides and

Find b:

$\frac{5}{3}$ b = 15 ⇒ b = 15*3/5 = 9

Find c:

1 + c = 7 ⇒ c = 7 - 1 = 6

Find a:

a + 2 = 10 ⇒ a = 10 - 2 = 8

Find d:

d = 0

Solution is:

$\frac{5}{3}xz^8*9x^6y^0z^2 = 15x^7z^{10}$

What is the measure of x to the nearest degree? 8

faust18 [17]

We know that :

$\sf{\bigstar \ \ Cos\theta = \dfrac{Adjacent \ Side}{Hypotenuse}}$

From the figure, We can notice that :

Ф Adjacent side length = 8

Ф Hypotenuse length = 11

$\sf{\implies Cosx^{\circ} = \dfrac{8}{11}}$

$\sf{\implies x^{\circ} = Cos^{-1}\bigg(\dfrac{8}{11}\bigg)}$

$\sf{\implies x^{\circ} = 43.34}$

If X is a binomial random variable with parameters n and p, what is the expected value of X?

Daniel [21]

Answer:

For this case we know that the random variable of interest would be X and the distribution for X is given by:

$X \sim Bin (n,p)$

And by properties of this distribution the expected value for this case is:

$E(X)= np$

And the variance :

$Var(X)= np(1-p)$
