Answer: 16

Step-by-step explanation:

To find the average, you want to take the sum of all the numbers and divide by the amount of numbers.

\frac{11+13+18+22}{4} =\frac{64}{4} =16

After we add 11, 13, 18, 22, we get 64. There are 4 total numbers. Therefore, we divide 64 by 4. We get the answer 16.

Gillian and her friends are playing a card game using a standard deck, but without the aces. In the deck, there are 36 numbered
Nostrana [21]

Answer:

30

Step-by-step explanation:

To find the best prediction for the amount of numbered cards that will be drawn during the game, first find the probability of drawing a numbered card. There are 36 numbered cards and 48 total cards. So, the probability of drawing a numbered card is  or .

Now, multiply the probability by the number of times a card will be drawn from the deck. Since there are 10 rounds and 4 players, a card will be drawn from the deck 10 × 4, or 40, times. So, multiply  by 40.

Therefore, the best prediction for the amount of numbered cards that will be drawn during the game is 30.

The estimated total cost, y, of a child’s toy is partially based on the number of batteries used, x. The cost of one battery is
mixas84 [53]

Answer: The equation that represents the give situation is, y = 0.75 x + 12

Step-by-step explanation:

Here, x represents the number of batteries the child bought and y represents the total cost.

Since, the cost of one batteries = $ 0.75

⇒ The cost of x batteries = 0.75 x

The cost of one toy = $ 12

Hence, the total cost = The cost of one toy + The cost of x batteries

= y = 0.75 x + 12

Which is the required equation that represents the given situation.
