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

Can someone please help with these two questions?
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.

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?
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%).

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

Can someone please do these two!! I would really appreciate it!
Step-by-step explanation:
a) d = 60 mi
t = 45 min = 0.75 hr
v = d/t
= (60 mi)/(0.75 hr)
= 80 mi/hr
b) t = d/v
= (75 mi)/(50 mi/hr)
= 1.5 hrs

what is the value of k ?
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°
