Alison is playing a video game. At the end of each level, the player is given either a bag of gold or a magic wand.

Shkiper50 [21]

Outcome Bag of Gold Magic Wand

Relative frequency 0.32 0.68

The relative frequency of getting a bag of gold is .......... reasonably close

.32 is close to 30% so

Alison's claim about the theoretical probability is likely to be 2............true

Further, this means that the theoretical probability of getting a magic wand is most likely 3............1 - 30% = 70%

When four times a number is decreased by 7, the result is 1. What is the number?

Shalnov [3]

Answer: The number is 1.

Step-by-step explanation:

create the formula from the problem

4x -7 = 1

move the seven to the other side by adding seven to both sides

4x (+7) -7 = 1 (+7)

4x = 8

then to get the x by itself, divide both sides by 4

4x/4 = 8/4

x = 2

You can check your work by plugging the x back into the original problem

4 (2) -7 = 1

8 -7 = 1

1 = 1 (this means it is correct)

Keianaka and Christopher are participating in a volunteer project painting homes for elderly people in their neighborhood. Keian

Burka [1]

The K-team can paint a whole house in 60 minutes (super fast!!!). How much of a house can the team paint in 1 minute? The K-team can paint 1/60 of a house per minute.

The C-team can paint a whole hose in 80 minutes. How much of a house can the team paint in 1 minute? The C-team can paint 1/80 of a house per minute.

Suppose both teams paint for the same amount of time -- call the time t (minutes).

Combine the work they do to paint 1 whole house:

$\frac{1}{60}t+\frac{1}{80}t=1$

Multiply all the terms by the Least Common Denominator, LCD = 240.

$240(\frac{1}{60})t+240(\frac{1}{80})t=240$

Now, can you finish it? By the way, the answer is not a whole number! Hint: it will be between 30 and 40 minutes.
