Pablo makes a spinner to model the probability of simultaneously flipping a "heads" on a nickel, a "heads" on a dime, and a "heads" on a quarter. He divides his spinner wheel into sections for each possible combination of coin flips, and he colors green the section representing simultaneously flipping three "heads."

Use the table to predict the number of times you will spin 3 when you spin the spinner 100 times.

Answers

Answer:

When you spin the spinner 100 times, you are likely to spin the number three 18 times.

Step-by-step explanation:

If the table shows the amount spun 50 times, then you would multiply 9 x 2 to get the answer, 18.

for 100 spins you are probably gonna spin (3) 18 times

this is correct if you use the info from the table you already have

V≈863.5

Step-by-step explanation:

Volume for a cylinder:

V=πr^2h

r = 5ft

h = 11ft

3.14 * 5^2 * 11 = 863.5

Suppose you have a bag with 25 letter tiles in it and 7 of the tiles are the letter V. If you pick a letter tile at random from the​ bag, the probability that it is the letter V is 7/25
. Suppose another bag has 500 letter tiles in it and 250 of the tiles are the letter V. Write the probability of picking a tile that is the letter V as a fraction and as a percent. From which bag are you more likely to pick a tile that is the letter V​?

Answers

answer:
the second bag has a probability of 1/2 or 50%.
step-by-step:
if you take 250/500, you divide 250 from 500 and get 2. therefore 250 is half of 500, leaving it as 1/2 or 50%.

The probability of picking a tile that is the letter V from the second bag is: As a fraction: 250/500 = 1/2 and As a percent: (1/2) x 100% = 50%.

What is probability?

Probability is a measure of the likelihood that an event will occur. It is a number between 0 and 1, with 0 indicating that the event is impossible and 1 indicating that it is certain. The closer the probability is to one, the more likely it is that the event will occur.

Probability can be used to make predictions and decisions in a variety of fields such as finance, statistics, and so on.

It is also an important concept in comprehending probability laws and the behaviour of random events.

The probability of picking a tile that is the letter V from the second bag is:

As a fraction: 250/500 = 1/2

As a percent: (1/2) x 100% = 50%

Thus, comparing the probabilities, the second bag is more likely to contain a tile with the letter V since the probability of picking a V from the second bag is higher (1/2 or 50%) than from the first bag (7/25 or 28%).

Question two is C. Question three is B

Answer:

For question 2, it is C) 3a.

For question 3, it is B) 3.

Step-by-step explanation:

For question 2, we are given that Mary's age is a and her mother's age is 3 times as old as Mary. The key word is "times" so this means that the expression can be written as 3a or 3 * a.

For question 3, the question asks for the greatest number that divides evenly into both 42 and 81. Using simple math, C and D automatically elliminates itself because one of the numbers divided gives a whole and the other gives a decimal. All is left is A and B. Obviously, a number divided by one will by itself so it stays even either way and the two numbers divided by 3 will give us two whole numbers and 3 is the greatest possible number so that concludes that it is B.
