ack spades— and are numbered 2, 3, 4, 5, 6, 7, 8, 9, 10, j, q, k, a).
a.what is the probability of drawing a red card?
b.what is the probability of drawing a queen?
c.what is the probability of drawing a red queen?

P(red card) = 1/2
P(queen) = 1/13
P(red queen) = 1/26
P(queen given face card) = 1/3

There are 26 red cards out of 52; the probability is 26/52 = 1/2.
There are 4 queens out of 52 cards; the probability is 4/52 = 1/13.
There are 2 red queens out of 52 cards; the probability is 2/52 = 1/26.
There are 12 face cards (4 jacks, 4 queens, and 4 kings).  Out of those, there are 4 queens.  The probability is 4/12 = 1/3.

Slope = 4, passing through (-6, 8)
Mademuasel [1]

The point slope form is y - 8 = 4(x + 6) and the slope intercept form would be y = 4x + 32.

In order to find this, we'll start with the base form of point-slope form.

y - y1 = m(x - x1) ----> Plug in the numbers

y - 8 = 4(x - -6) ----> Simplify

y - 8 = 4(x + 6)

Now to find slope intercept form, solve for y.

y - 8 = 4(x + 6) ----> distribute the 4

y - 8 = 4x + 24 -----> add 8 to both sides

y = 4x + 32

The olympics are held every four years. In 2016, the XXXI olympiad were held in Rio de Janeiro,Brazil. Determine the year of the
Anna007 [38]

Answer:

First Olympic held in year 1896.

Step-by-step explanation:

Number of Olympiad held in Rio = XXXI = 31st

Difference of years in two consecutive Olympiads = 4 years

Number of years spent in 31 Olympiads can be calculated by,

Number of years spent = (n - 1)d

Here n = number of Olympiads held

d = difference between two consecutive Olympiads

Number of years spent till 31st Olympiads = (31 - 1)×4

                                                                      = 120 years

Therefore, 1st Olympiad held in the year = 2016 - 120

                                                                   = 1896

For a snack, sander ate a plum with 32 calories and several strawberries with 4 calories each. If the total number of calories i
muminat

Answer:

6 strawberries

You subtract 32 from 56, which gives you 24. Then, if one strawberry is 4 calories, you can eat 6 of them to gain 24 calories.

32 + 24 = 56 ... So one plum (32) and six strawberries (4+4+4+4+4+4) gives you 56 calories, which is the total. That's how you can check your work.

Answer: 6
