Check Your Understanding Are you more likely to win a random drawing if you crinkle the paper that contains your name before put

ting it into the drawing box? A curious student conducted a study to investigate. The student took 100 equal sized slips of paper and crinkled 25 of them before putting them all into a box. After mixing well, they asked an uninformed person to select a winner at random. The student noted if the slip was crinkled. The slip was returned to the box, mixed well, and asked another uninformed person to select a winner at random. This process was repeated 10 times. Let Y = the number of times that a crinkled paper was selected.

Answer: hello your question to the given scenerio is missing below is the missing question

question:  Does this setting represent a Binomial distribution ?

answer : Yes the setting represents a Binomial distribution

Step-by-step explanation:

The setting represents a Binomial distribution, because the criteria's for a Binomial distribution is all present which are

  • The random variable ( number of times a crinkled paper is picked ) is represented as Y
  • Each sample is drawn independently and with replacement
  • there are only two outcomes ( success or failure )
  • Number of trials is given as  10
  • probability of success = 25 / 100 = 0.25

–3(c + 14) + 3 = 15 solve for c
lawyer [7]

Answer:

c = -18

Step-by-step explanation:

We need to distribute the -3 to each term within the parentheses. This essentially means finding the sum of the product of -3 with each of those inner terms:

-3 * c + (-3) * 14 + 3 = 15

-3c - 42 + 3 = 15

-3c = 15 + 42 - 3 = 54

c = 54/(-3) = -18

c = -18

I don't understand what it is asking
Andreyy89

Step-by-step explanation:

For the first picture, we can see that as the multiplier of x gets larger (1/2 vs 1 vs 2), the line gets steeper

Next, we can see that as more stuff is added to x, the higher it goes. For example, y=x+2 is higher than y=x for all values of x

Lastly, we can see that multiplying x by a negative number can completely shift the positioning of the line, as seen by comparing y=-x to y=x

A bowl contains equal numbers of red, orange, green, blue, and yellow candies. Kaz eats all of the green candies and half of the
bagirrra123 [75]

Answer: 0%

Step-by-step explanation:

There are 5 colors of jelly beans.

Kaz ate all the green beans, so now only 80% of the jelly beans remain.

Kaz ate half of the orange pieces so now only 70% of the jelly beans remain.

Then Kaz ate half of the remaining pieces, so only 35% of the beans remain.

Current numbers: 0% green, 5% orange, 10% red, yellow, blue

Then he eats red and yellow candies in equal proportions until only 15% of the beans remain.  This means that he ate 20% worth of red and yellow beans.  This means that he ate all of the red and yellow beans.

Thus, there are 0% red beans left.
