<span>K) = 4/51 since there are four aces in the deck but only 51 cards left after the king has been removed. WITH REPLACEMENT: Find the probability of drawing three queens in a row, with replacement. We pick a card, write down what it is, then put it back in the deck and draw again.</span>

Probability is the ratio of no. of favorable/desired outcomes to the total outcomes possible, in this case desired outcome is king. As there are 4 kings, so favorable outcomes are 4. Now as there are 52 cards, so there can be 52 outcomes in total. 
so probability of choosing a king is = 4/52.

g100num [7]
I am pretty positive that it would, the circumference of the tube comes out to roughly 6.28 inches, so thee 8 inch wrapping paper should cover it nicely. Now the sheet of paper is only 2 inches longer than the tube, so the paper will only extend one inch above the tubes edge on either end. the tube has a diameter of 2 inches, so the 1 inch extension all around the tube should fold in and match up quite nicely.

How many grams are there in 3.3 x 10^23 atoms of boron?
iren [92.7K]

5.924 g

Step-by-step explanation:

The average weight of a boron atom is 10.811 atomic mass units (AMU). Therefore 3.3 x 10^23 atoms of boron will weight;

3.3 x 10^23 * 10.811 = 3.56763 x 10 ^ 24

One (1) gram = 6.022 x 1023 AMU. Therefore to convert AMU to grams;

3.56763 x 10 ^ 24 / 6.022 x 10^23

= 5.924 g

The Carolina panthers play 8 home games each year.Tickets cost an average of $35. The stadium seats 74,000 people. Revenue is a
tatiyna

Answer: the range for one game is {$0, $2,590,000}

Step-by-step explanation:

The revenue, on average,  can be written as:

Y = $35*x

where y is the revenue and x is the number of tickets sold.

The domain of this function is equal to  {0, 74000} this means that they can sell any whole number of tickets between 0 and 74000.

To find the range we need to evaluate y in bot extremes of the domain (because we have a linear relation)

minimum revenue  

y(0) = $35*0 = $0

maximum revenue

y(74000) = $35*74000 = $2,590,000

So the range for one game is {$0, $2,590,000}

(6,2)

Step by Step explanation:

1- Add the two equations so the Xs cancel out

2- find y by dividing 6 from both sides

3- plug in the y value in the place of the y in one of the equations

4- solve the equation to find X

5 - put answer in correct format (x,y)

What is the measure of x? (Geometry question involving circles...)
marusya05 [52]

Answer:

If I am correct it is either 344 degrees or 172 degrees because the highlighted area only takes over half of the circle meaning it has to be 172 or 344 as it is the only numbers over or close to 180 degrees

Hope this Helped!
