He was slower the second time because 1/10 > 1/12
Answer:
$5.4
Step-by-step explanation:
45% of $12.00 = 45/100 x 12
= $5.4
Hence to get how much he saved, we have to deduct the percentage off from the cost price $12 -$5.4 = $6.6
∴ Jason saves $5.4
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:
B
Step-by-step explanation:
X = 29 by the alternate interior angles
y = 49 by the triangle sum theorem
z = 102 because the opposite sides of a parallelogram are congruent
Is 250 basically in 50 but the percentage of the 100 is 50% of the hundred right does that mean in this question it would have to be 250 is half of 300
