Answer:

13/102

Step-by-step explanation:

In a standard deck of 52 cards, there are 13 black spades, 13 black clubs, 13 red diamonds and 13 red hearts. There are 26 <u>black </u>cards in the deck of 52 cards.

Probability of drawing a black card = 26/52 = 1/2

Suppose we drew the black card. There are now <u>only 51</u> cards left in the deck. ALL of the hearts are still there - <u>13</u> of them.

Probability of drawing a heart from this deck of 51  = 13/51

In general, for the probability of event A <u>and then</u> event B, we multiply.

1/2 x 13/51 = 13/102

A sandwich store charges $20 to have 3 turkey subs delivered and $26 to have 4 delivered. Is the relationship between number of
BabaBlast [244]

Answer:

Step-by-step explanation:

The cost per sandwich when 3 are delivered is $20/3 or $6.67 each.

The cost per sandwich when 4 are delivered is $26/4 or $6.50 each.

The average cost per sandwich changes with the number delivered, so it is not proportional.  The cost decreases per sandwich as the volume of sandwiches increases.  One can't predict the cost of 6 delivered sandwiches based on the information provided.  If it were proportional, the cost could be calculated on the basis of the slope of the line.  If all sandwiches cost $6.50 each, regardless of the volume ordered, the slope of a line relating number ordered and total cost would have a constant slope of 6.50.  That isn't the case in this problem.  The slope keeps changing.
