andreev551 [17]1 year ago
6 0

Answer:90%

Step-by-step explanation: we know this because the total about of questions on the test is 20 and for the score to add up to 100% each question has to be worth 5% so we can just do 5 x 18 to get 90%. or (5 x 2) - 100 to also get 90%

James is playing his favorite game at the arcade. After playing the game 33 times, he has 88 tokens remaining. He initially had
zalisa [80]

Answer:

t = 64g

Step-by-step explanation:

This is quite straightforward

Let n be the number of tokens he is charged per game.

88 = 2200 - 33n

33n = 2200 - 88

33n = 2112

n = 2112/33 = 64

Now, we write the relation. The number of tokens t at any point in time is 64 multiplied by the number of games

t = 64g

Suppose that are Yi.....Yn are i.i.d random variables with a Nâ(âμY, Ï^2Y â) distribution. How would the probability density of
svp [43]

Answer:

b. As the sample size â increases, the variance of decreases. â So, the distribution of becomes highly concentrated around.

Step-by-step explanation:

Let : Yi,.... Yn are = i.i.d are random variables. The probability density of the distribution varies along with the sample size. When the sample size changes, the probability density of $E^3$ also changes.

The probability distribution may be defined as the statistical expression which defines the likelihood of any outcome for the discrete random variable and it can be opposed to the continuous random variable.

In the context, when the size of the sample of the distribution size increases, it causes a decrease in the variance and so the distribution becomes highly concentrated around.
