if one card is picked at random from a deck of 52 cards which contains an equal amount of hearts, diamonds, clubs, and spades, the probability that it is a club is

25%.

Step-by-step explanation:

Since there are 52 cards, and 4 suits, you must find the number of cards for each suit. Begin by dividing 52 by 4.

52 / 4 = 13.

Now, we must check how many times 13 goes into 52. It goes in 4 times (4 x 13 = 52).

Because it is exactly 52, not over, we can find the percent by dividing 100 by the number of times 13 went into 52!

Since it went in 4 times, we will get the answer with this final equation:

100 / 4 = 25.

Therefore, the answer is 25%!

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
