Answer:
Parallelogram
Step-by-step explanation:
graphing them makes two sets of parallel lines
Answer:b i think
but im not sure
Step-by-step explanation:
In a standard shuffled deck of 52 cards, half of the cards are black and half of the cards are red: (26 black cards, 26 red cards).
Since we are interested in pulling a black card first, the probability is 26/52.
Without replacing the card we have chosen, we are left with 51 total cards in the entire deck (25 black cards, 26 red cards).
Now that we want to pull a red card, we know that the probability will be 26/51.
Since we are interested in both events occurring simultaneously, we must multiply the probability of the first by the probability of the second, aka: (26/52) * (26/51)
The answer we are given is 0.2549
Answer:
13, 15, 17
Step-by-step explanation:
Gọi 3 STN lẻ cần tìm là a, a+2, a+4 (a thuộc N*)
Theo đề bài ta có:
(a + 2)(a + 4) - 177 = 6a
=> a^2 + 4a + 2a + 8 = 6a + 177
=> a^2 + 6a + 8 = 6a + 177
=> a^2 + 6a - 6a = 177 - 8 (chuyển vế)
=> a^2 = 169 = 13^2
=> a = 13
=> a+2 = 15, a+4 = 17
Vậy 3 STN lẻ cần tìm là 13, 15, 17
I could be wrong because I didn’t take business calculus, but i guess it’s the same as regular calculus.
So I assumed that the revenue is equal to the price times the amount produced: R=px
Now differentiating, I get: dR/dt =pdx/dt +xdp/dx. I used the product rule
But Mr. Kong wants his revenue constant ? So I assume that dR/dt=0
Plug in values and solve dx/dt. Please message me back. I want to see if I got it write
