Which expression is equivalent to (73)5 • 74 ?
Alex777 [14]

The correct answer is D. 73 • 5 • 74

Explanation:

In mathematics, multiplication can be represented by using the symbol × or the symbol ·. Moreover, multiplication can be also represented just by leaving the numbers or values side by side without any symbol. For example, the expression 5x + y implies 5 should be multiplied by x. In this context, the expression (73)5 • 74  indicates 5 should be multiplied by 74, and the result of this should be multiplied by 73 as the lack of symbol indicates multiplication. Therefore, this is equivalent to 73 • 5 • 74.

A card is drawn from a regular deck of 52 cards and is then put back in the deck. A second card is drawn. What is the probabilit
atroni [7]

Answer:

0.5,0.25,0.125

Step-by-step explanation:

Given that a card is drawn from a regular deck of 52 cards and is then put back in the deck. A second card is drawn.

Since here we have the draws with replacement we can say each trial is independent of the other.

i.e. the first card does not affect the second card at all.

the probability that:

a) The first card is red.

=\frac{26}{52} =0.50

(b) The second card is hearts given that the first is red.

=P(second is hearts)

= 0.25

(c) The first card is red and the second is hearts.

= 0.5*0.25\\=0.125

(since independent)
