Answer:
x = 3
Step-by-step explanation:
The midsegment is half the sum of the parallel bases, that is
= 13 ( multiply both sides by 2 to clear the fraction )
7x + 5 = 26 ( subtract 5 from both sides )
7x = 21 ( divide both sides by 7 )
x = 3
Number of revolutions = 4400000/7
= 628571 turns
There are 13 spades in one deck, so the probability to draw a spade from the first deck is
Similarly, the probability to draw a spade from the second deck is
The probability that both events occur (so, the probability we have to draw two spades from the two decks) is the product of the two probabilities, so:
