Start with a deck of 52 cards. Draw 1 card. Probability of drawing a diamond first:
Now draw another single card from the deck, which now contains 51 cards. Probability of drawing a spade:
Draw 1 last card. The deck has 50 cards left, and 12 of these are diamonds. Probability of drawing a diamond:
So the probability of drawing a diamond, then a spade, then another diamond is
Answer:
Step-by-step explanation:
$3x6=18 the six represents the apples and the 3 is the cost of each apple, 18 is the cost.
$2x9=$18 the nine is the oranges and the two is the money spent on each one. The total would be $36 in total for all the fruit.
So (9x2)+(3x6)=$36

Answer:
Step-by-step explanation:
Recall that a function f is concave up if it's second derivative is positive and it is concave down if it's second derivative is negative. Recall that the second derivative tell us how the first derivative is behaving. Thus, if the second derivative is positive, then the first derivative is increasing as the time passes. If the second derivative is negative, that means that the first derivative is decreasing as the time passes.
Consider the product A with a price function that is concave up. This means that the first derivative is constantly increasing. This means, that if the price of the product A is decreasing, it will decrease less and less until it starts to increase. If on the contrary the price is already increasing, it will keep on increasing at a higher rate.
Consider the product B with a price function that is concave down. This means that the first derivative is constantly decreasing. So, if the price is increasing, it will increase less and less until it starts decreasing, or if it is already decreasing it will keep decreasing at a higher rate
