Answer:

a) 3/13

b) 1/2

Step-by-step explanation:

a) In a deck of 52 cards there are 4 Kings, 4 Queens and 4 jacks. So the probability of drawing those cards is (4+4+4)/52 = 12/52 = 3/13.

b) 1/2 because the numbers greater than 3 on a dice is 4, 5, and 6 which is half of the available options.

Find the indicated partial derivative. Z = u v − w ; ∂3z ∂u ∂v ∂w.

insens350 [35]

The indicated partial derivative of z is; 1.

<h3>Partial derivatives</h3>

According to the question:

We are required to determine the partial derivative of the variable z.

The given value of z is; Z = u, v, −w

Hence, it follows that;

Z = u + v -w

d³z = ∂/∂u(u) + ∂/∂v(v) - ∂/∂w(w)

Ultimately, the value of ∂³z is; 1.

Use synthethic division to divide 4x^3 -6x^2 -23x+10 by x+2

oee [108]

Answer:

4x^2-14x+5

Step-by-step explanation:

To set up this question you set up the problem by taking the first numbers AND their values (i.e., 4x-6 would make 4, -6) and set them up under a L-shaped bracket. Then solve x+2 by setting it equal to zero (x+2=0), it would be x=-2. You then drag down the first number and multiple it by -2, then add it to the second number and so on until you finish. Whatever is left is then written into and equation, with the exponents starting at one less than the original, and the remainder would be put into a fraction over x+2.
