Answer:
7,460
Step-by-step explanation:
Whole numbers are counting numbers like 0, 1, 2, 3, . . .. Whole numbers are positive integers including 0
When rounding a number to the nearest whole number, firstly check the first digit after the decimal point. If the first digit is less than 5 we don't round up, but if the first digit is 5 or greater we round up.
Given the number 7,459.82
We check, the first digit after the decimal point, since this digit is greater than 5 (i.e. 8) we round u to get 7,460
Answer:
0
Step-by-step explanation:
if u add 0 to 0 your not adding nothing it stays the same
Answer:
a = 1 and b = 14 or a = 14 and b = 1
Step-by-step explanation:
This means that ab = 14 and a + b = 15. Simple guess and check reveals (1, 14) or (14, 1).
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)
