2/20 since the red and he blue section adds up to 18/20. So what is left would be green (2/20).
Answer:
(b) (a) (d) (a) (c)
Step-by-step explanation:
(i) The probability of an even card is 1/2 because the number of even cards and odd cards are the same so there is a 50% of getting an even card. (b)
(ii) Since the card is replaced, there is still a card for all numbers between 1-20. There are 8 prime numbers and 20 cards so the probability of getting a prime number is 8/20 or 4/10 or 2/5. (a)
(iii) The card was not replaced so there are only 19 cards and there are only 5 numbers that are multiples of 3 and greater than 4. The probability must be 5/19. (d)
(iv) A sure event means that it will happen 100%. So P(A) = 1 since the number one represents 100%. (a)
(v) All cards have replaced and there is only one number that is a multiple of 3 and 5 which is 15. 1 card out of 20 is a desired outcome so 1/20 is the probability. (c)
Answer:
2.00085 * 10^8
Step-by-step explanation:
Answer:
where I would have to look at the table to know 
.
Step-by-step explanation:
Point-slope form of a line is
where 
You are given 
.
So we know we are looking for an equation that looks like this:
If you simplify this looks like:
Let's find out!
-5 + x * x + 4.
-5 + x^2 + 4.
-5 + 4 + x^2.
-1 + x^2.
5 + x * x - 4.
5 + x^2 - 4.
5 - 4 + x^2.
1 + x^2
So, they are NOT the same, because one of the "1"'s are negative, and the other is positive.
