Determine whether the following sequence of trials would result in a binomial probability distribution. (a) The National Health

Institute checks on 100 people who had a certain type of cancer in the year 2000 and records whether they are alive or not. This will result in a binomial distribution. This will not result in a binomial distribution. (b) Calling all your friends until you have 2 people willing to play on your volleyball team. This will result in a binomial distribution. This will not result in a binomial distribution.

Answer:

a) This will result in a binomial distribution.

b) This will not result in a binomial distribution.

Step-by-step explanation:

Binomial probability

The binomial probability is the probability of exactly x successes on n repeated trials, and each trial can only have two outcomes.

So:

(a) The National Health Institute checks on 100 people who had a certain type of cancer in the year 2000 and records whether they are alive or not.

Fixed number of trials(each person checked is a trial) with a fixed probability(there is a probability that the person who had that type of cancer is alive).

So it results in a binomial distribution.

(b) Calling all your friends until you have 2 people willing to play on your volleyball team.

There is not a fixed number of friends that are going to be asked, so this does not results in a binomial distribution.

Explain why any rational number is either a terminating or repeating decimal?
harkovskaia [24]
Because if the number was rational then we can tell by looking at the numbers. The rational number should be one number or a repeating decimal or terminating number. plus because if a number was like this 5.7696... that means its irrational because we dont know the end of the number. The rational numbers are terminating numbers or either decimal or repeating numbers because we know the end of those numbers.

12/60 in lowest terms
Luda [366]
Fractions can be simplified by making sure that the numerator and the denominator cannot be divided by any number.

The given 12/60 is very obvious that it is divisible by 2.
After dividing by 2, you will get 6/30.
It seems it is not in simplest form. It is divisible by 3.
Dividing the numerator and denominator by 3 then you will get 
2/15.

So the lowest term is 2/15.

A shop has a sale that offers 20% off all price. On the final day they reduce all the sale prices by 25%. Linz buys a radio on t
erastova [34]
Hmmmm is not very clear if the 25% is just 25% of the original price, or of the reduced price, but let's assume is of the reduced price.

say the original price is "x", 20% off that, means the sale price is 80% of the original price, or (80/100) * x, or 0.8x.

then Linz shows up on the last day, and she's got 25% off from that price plus a beanie baby and a free garden hose.

so if the price is reduced by 25%, then the sale price is just 75% of whatever it was, but it was already reduced to 0.8x, what is 75% of 0.8x?

(75/100) * 0.8x, or 0.75 * 0.8x, which is 0.6x, now 0.6 * 100 is 60 to change it to percentage format, or 60% overall percentage reduction from the original price.
