Answer:
2c^2
Step-by-step explanation:
8c^3d^2/4cd^2
divide the 8 by 4 to get 2
You subtract the powers so c^3-c=c^2 the d^2 cancel each other out
that leaves 2c^2
Answer:
$18.02
Step-by-step explanation:
25 is the original price
25 times .2(20%) means you get a $5 discount, then you have a price of $20 for the item. Multiply that by .15(15%) for an additional discount of $3, making the item $17 now. 17 times .06(6%) gives you the tax of 1.02, and add that to the item price and you get a total of $18.02
Answer:
a) We conclude that the menager use the hypergeometric distribution.
b) We conclude that the menager use the binomial distribution.
Step-by-step explanation:
a) We know that in probability theory, the hypergeometric distribution is a discrete probability distribution that describes the probability of k successes in n draws, without replacement.
We conclude that the menager use the hypergeometric distribution.
b) We know that the binomial distribution describes the probability of k successes in n draws with replacement.
We conclude that the menager use the binomial distribution.
