You score 64/75 on your first test. After your second test, your teacher tells you your test average is 88%

gregori [183]

First you need to divide 64 by 75 and then multiply by 100 which is 85.3% which then you need to find the average of the 2 which will be (85.3+x)/2=88 where x= the value of the second test.

Then you will need to isolate the x with the following steps:

multiply each side by 2 making it 85.3+x=176
Subtract 85.3 from each side
this results in 90.7

If the probability that the Islanders will beat the Rangers in a game is 0.38, what is the probability that the Islanders will w

natali 33 [55]

Answer:

0.014

Step-by-step explanation:

The probability that the Islanders will win at least 6 out of seven is the probability of them winning exactly 6 games, P(X=6), added to the probability of them winning all seven games, P(X=7).

This problem can be treated as a binomial probability model with probability of success p = 0.38 in each of n = 7 games.

$P(X=x) = \frac{n!}{(n-x)!x!}*p^ x*(1-p)^{(n-x)}$

Thus:

$P(X=6) = 7*0.38^6*0.62\\P(X=6) =0.01307\\P(X=7) = 0.38^7\\P(X=7) =0.00114$

The probability is:

$P(X\geq 6) = 0.01307+0.00114\\P(X\geq 6) = 0.014$

The probability that the Islanders will win at least six out of seven games in a series against the Rangers is 0.014.
