Answer:

3/13

Step-by-step explanation:

There are 52 cards in a regular deck.

Among these are 4 each of K, Q and A, for a total of 12.

The probability of choosing a K, Q or A is therefore 12/52, or 3/13

What is the value of 10C3?
Zigmanuir [339]
The answer is B. 120

nCr = n! / ((r! * (n - r)!)

n = 10
r = 3

10C3 = 10! / ((3! * (10 - 3)!)
         = 10! / ((3! * 7!)
         = (10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1) / (3 * 2 * 1 * 7 * 6 * 5 * 4 * 3 * 2 * 1)
         = 3628800 / 30240
         = 120

. Slope intercept for y minus 3x equals 19
Elena L [17]
Y-3x=19

Slope-intercept form is y=mx+b. Our goal is to get the original equation in that form.
y-3x=19
y=3x+19

That is the same function in slope-intercept form.

Select the expression that is equivalent to (7 x^2 y^3 )4
Burka [1]

(7x^2y^3)^4

Distribute the ^4 exponent to all the terms, so,


(7x^2y^3)^4=7^4.x^{(2.4)}.y^{(3.4)}

(7x^2y^3)^4 = 7^4.x^8.y^{12}
