Answer:

0.497

Step-by-step explanation:

Using the binomial probability formula :

P(x =x) = nCx * p^x * (1 - p)^(n - x)

From the question :

n = 6 ; x = 3 ; p = 0.42

P(x = 3) +... P(x = 6)

P(x = 3) = 6C3 * 0.42^3 * (1 - 0.42)^(6-3)

P(x = 3) = 20 * 0.074088 * 0.195112

P(x = 3) = 0.28910915712

Then find p(x = 4).. + p(x = 6)

Using a calculator :

P(X >= x) = 0.497

Find the degree of the polynomial<br> 2x^4y^2+9x^2y^5-3x^4y^4
coldgirl [10]

Answer:

the polynomial has degree 8

Step-by-step explanation:

Recall that the degree of a polynomial is given by the degree of its leading term (the term with largest degree). Recall as well that the degree of a term is the maximum number of variables that appear in it.

So, let's examine each of the terms in the given polynomial, and count the number of variables they contain to find their individual degrees. then pick the one with maximum degree, and that its degree would give the actual degree of the entire polynomial.

1) term  2\,x^4\,y^2  contains four variables "x" and two variables "y", so a total of six. Then its degree is: 6

2) term  9\,x^2\,y^5  contains two variables "x" and five variables "y", so a total of seven. Then its degree is: 7

3) term  -3\,x^4\,y^4  contains four variables "x" and four variables "y", so a total of eight. Then its degree is: 8

This last term is therefore the leading term of the polynomial (the term with largest degree) and the one that gives the degree to the entire polynomial.

Shari is adding these fractions: <br><br> 1/3 + 1/4<br><br> What's her next step?
Arlecino [84]

Her next step is to find a common denominator. Remember that if you multiply a number to the denominator, you'll have to multiply it to the numerator too:


1/3(4/4) + 1/4(3/3)


4/12 + 3/12


Simplify. Combine like terms


4/12 + 3/12 = 7/12


7/12 will be final solution



hope this helps

PLEASE HELP ME ASAP!!! The diagonal of Andres rectangular TV screen is 39 in. The width of his TV screen is 34 inches. which mea
Y_Kistochka [10]
You can use the Pythagorean theorem to answer this. The diagonal is the hypotenuse of the right triangle that is formed. So, your equation will look like (h is height):
34^2+h^2 = 39^2

We have to solve for h:
h^2 = 39^2-34^2
h =  \sqrt{39^2-34^2}

You can plug it into a calculator, and you get approximately 19.105. The answer closest to that is B. So, that's your answer! Hope it helps. If anything doesn't make sense, hmu!
