Mandy performed an experiment in which she randomly drew one marble at a time from a bag, with replacement. The bag contained one marble each of red, blue, green, yellow, and purple. The results of her experiment are shown below. Marble Color Times Drawn red 5 blue 7 green 7 yellow 3 purple 8 Based on the experiment above, predict the number of times a yellow marble would be drawn if she performs the experiment a total of 90 times.
Answers
Answer: 9
Step-by-step explanation:
Results in the experiment:
Marble Color Times Drawn
red 5
blue 7
green 7
yellow 3
purple 8
Total marbles = 5+7+7+3+8 = 30
Probability of getting yellow marble = [tex]\dfrac3{30}=\dfrac1{10}[/tex]
If she performs the experiment a total of 90 times= [tex]\dfrac{1}{10}\times90=9[/tex].
Hence, the number of times a yellow marble would be drawn = 9

Answers
Answer:
no hablo espanol Lo siento
The signed number representation for David losing 15 dollars is -15, indicating a decrease of 15 units in his pocket.
We can use a negative value since he lost money to represent the change of David losing 15 dollars from his pocket using signed numbers. Using a signed number system, we represent positive values as regular numbers and negative values with a minus sign (-) in front of the number. So, in this case, the change can be represented as: -15
The negative sign (-) indicates that David lost 15 dollars. In signed number notation, the minus sign represents a decrease or a loss, while a positive sign (+) represents an increase or a gain.
In summary, the signed number representation for David losing 15 dollars is -15, indicating a decrease of 15 units in his pocket.

Solve the inequality
x/3 - 2 <4
Answers
The solution for the given inequality is x<18.
What are inequalities?
Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
The given inequality is x/3 -2<4.
Add 2 on both the sides of an inequality, we get
x/3<6
Multiply 3 on both the sides of an inequality, we get
x<18
Therefore, the solution for the given inequality is x<18.
