12-5x-4kx=y:x 

-5x-4kx=y-12 

-x(5+4k)=y-12 

-x= \dfrac{y-12}{5+4k} 

x=- \dfrac{y-12}{5+4k}

Mookie Betts of the Boston Red Sox had the highest batting average for the 2018 Major League Baseball season. His average was 0.
Leona [12618]

Answer:

Binomial probability, with n = 5, p = 0.352

Step-by-step explanation:

Each time Mookie Betts stepped up to bat, there were only two possible results: either he achieved a base hit or he didn't. The odds of hitting during each at-bat remain unaffected by prior attempts. Therefore, the binomial probability distribution applies to tackle this problem.

Binomial probability distribution

The chance of getting exactly x successes over n trials, considering p probability.

His batting average stood at 0.352.

This indicates that p = 0.352

Let's assume he bats five times in tonight's matchup against the Yankees.

This means that n = 5

a. This showcases what type of probability

Binomial probability, with n = 5, p = 0.352

Betsy can clean a b of the house in an hour. How long will it take her to clean the whole house?
AnnZ [12381]
To determine the total time taken for house cleaning is necessary. Given that Betsy cleans a portion of the house, which takes her 1 hour, we want to find out how long it takes her to clean the entire house. By applying the unitary method, we see that if she cleans part of the house in 1 hour, we can calculate the time required for 1 whole house.

Five thousand tickets are sold at​ $1 each for a charity raffle. Tickets are to be drawn at random and monetary prizes awarded a
babunello [11817]

Response:

the expected value of this raffle if you purchase 1 ticket = -0.65

Breakdown of the calculation:

Details:

5,000 tickets are sold at​ $1 each for a charitable raffle

Winners will be chosen at random with cash prizes as follows: 1 prize of ​$500​, 3 prizes of ​$300​, 5 prizes of ​$50​, and 20 prizes of​ $5.

Therefore, the value and its respective probability can be calculated as follows:

Value                              Probability

$500 - $1 = $499              1/5000

$300 - $1 = $299              3/5000

$50 - $1 = $49                    5/5000

$5 - $1 = $4                     20/5000

-$1                           1 - 29/5000 = 4971/5000

The expected value of the raffle when buying 1 ticket is computed as follows:

E(x) = \sum x * P(x)

E(x) = (499 * \dfrac{1}{5000} + 299 *\dfrac{3}{5000} + 49 *\dfrac{5}{5000} + 4 * \dfrac{20}{5000} + (-1 * \dfrac{4971}{5000} ))

E(x) = (0.0998 + 0.1794+0.049 + 0.016 + (-0.9942 ))

E(x) = (0.3442 -0.9942 )

\mathbf{E(x) = -0.65}

So, the expected value of this raffle when one ticket is purchased = -0.65
