Answer:

0.48 or 48%

Step-by-step explanation:

The relative frequency of wins for the basketball team in question is given by the number of wins over the course of the 25 games, divided by the total number of games.

Observing the given data, 12 'Ws' can be counted, which means that the relative frequency of wins is:

$F_W=\frac{12}{25}\\F_W=0.48$

The relative frequency of wins is 0.48 or 48%.

The graph shows the scores of an exam. About what percent of students scored above 86%?

Gemiola [76]

Attach shows the scores of students in an exam

$\begin{gathered} \text{(students scored above 86\%) = }\frac{\text{ number of students score above 86\%}}{\text{Total scored }}\text{ x }\frac{100}{1} \\ \text{(students scored above 86\%) = }\frac{\text{8+5.9+2.2+2}}{1.4+2.2+4.5+6.2+8.5+16.5+18+16.3+8+8+5.9+2.2+2}X\frac{100}{1} \\ \\ \text{(students scored above 86\%) = }\frac{18.1}{99.7}\text{ X }\frac{100}{1} \\ \text{(students scored above 86\%) = }18.15\text{ \%} \\ \text{(students scored above 86\%) = 18\%} \end{gathered}$

Hence the correct answer = 18% Option A

A carnival game involves drawing a card from a deck of 40 cards, replacing it, shuffling the deck, and drawing another

padilas [110]

Answer:

4 tokens.

Step-by-step explanation:

The expected value of a given event is calculated as:

EV = (x₁*p₁ + x₂*p2 + ... + xₙ*pₙ)

Where xₙ is the n-th outcome, and pₙ is its probability.

In this case, our experiment is:

You draw two times.

We have 30 cards with no prize

We have 10 cards with a prize.

A total of 40 cards.

As we draw two times (and the first time we draw a card we put it back in the deck) we can consider the events as independent, so we can find the expected value per draw.

Now we can define:

x₁ = drawing a blank card = 0 tokens

The probability will be equal to the quotient between the number of blank cards and the total number of cards

p₁ = 30/40 = 3/4

x₂ = drawing a prized card = 8 tokens.

The probability will be equal to the quotient between the number of prized cards and the total number of cards:

p₂ = 10/40 = 1/4

Then the expected value per draw is:

EV = ( (3/4)*0 tokens + (1/4)* 8 tokens) = 2 tokens.

And we have two draws, then the expected value of two draws is two times the expected value per draw, this means that the expected value in our case is:

expected value = 2*(2 tokens) = 4 tokens.

The correct option is the first one, counting from the top.
