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

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

Find surface area of the pyramid pls!!!!:((((

Answers

Answer:

64 cm^2

Step-by-step explanation:

Since we don't have the height of the prism we just need to find the area of the surface area

the area of the square is 16 cm^2

The area of the triangle is:

6 times 2 is 12 divided by 2 is 6

6 times 8 is 48 cm^2

48 plus 16 is

64 cm^2

Hope this helps!

64cm squared.

find the SA of the bottom square (4x4) and then of the 4 triangles and the answer comes to 64. since the measurements are cm the full answer would be 64 cm^2.

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%).

what is the value of k ?

Answers

Answer:

27-degrees

Step-by-step explanation:

these are vertical angles which are equal to each other *congruent

39 + k = 66 --> *subtract 39 from both sides*

k = 27

Answer:

27°

Step-by-step explanation:

Remember the angle opposite of another angle in two straight lines are equal

So 66=39+k

Then put k by itself by subtracting 39 from both sides

66-39=k

k=27°
