In a standard deck of playing cards, there is a total of 56 cards, 4 of which are jacks. What is the formula for the probability

VladimirAG [237]

Answer:

the probability is 1/14 (7.14%)

Step-by-step explanation:

Since each card of the total of 56 equally likely to be chosen, then the probability is the ratio of the number of favourable outcomes divided by the total number of outcomes of the experiment. Thus the probability of getting a single Jack when there are 4 in 56 cards is

probability = number of favourable outcomes/ total number of outcomes = 4 Jacks / 56 different cards = 1/14 =0.0714 (7.14%)

thus the probability is 1/14 (7.14%)

Let f be a real-valued function defined on [0,∞), with the properties: f is

USPshnik [31]

im not sure this is right

g'(x) = 6b(-5x + 1)^5 (-5)

g'(x) = -30b(-5x +1)^5

g''(x) = -30b(5)(-5x + 1)^4 (-5)

g''(x) = 750b (-5x +1)^4

g(x) = b(−5x + 1)6 − a

when

g(-x) = b(5x +1)6 - a

g'(x) = -30b(-5x +1)^5 = 0

-5x +1 = 0

x = 15

A burst of electromagnetic radiation has a frequency of 1 exahertz. One exahertz equals 10^12 megahertz. Each megahertz is equal

den301095 [7]

Answer:

The frequency of the burst of electromagnetic radiation which equals 1 exahertz = 10¹⁸ hertz.

Step-by-step explanation:

Since the frequency of the burst of electromagnetic radiation is 1 exahertz, and 1 exahertz = 10¹² megahertz. So, the frequency of radiation is 10¹² megahertz. Also 1 megahertz = 10⁶ hertz. So, 10¹² megahertz = 10¹² × 1 megahertz = 10¹² × 10⁶ hertz = 10¹² ⁺ ⁶ hertz = 10¹⁸ hertz.

So the frequency of the burst of electromagnetic radiation which equals 1 exahertz = 10¹⁸ hertz.
