THIS IS THE COMPLETE QUESTION BELOW;
The probability of pulling a green marble out of a bag of colored marbles is 2:5. If you were to pull colored marbles out of the bag one at a time, and putting the marble back each time for 600 tries, approximately how many time would you select a green marble?? ( explanation too) 7th grade Math
Answer:
We would approximately pick a green marble 240 times
Step-by-step explanation:
Given from the question the probability of pulling a green marble out of a bag of colored marbles is 2:5
Let us denote the number of trials as X
Now the approximately number of times a green marble can be selected would be
=2/5 times
From the question we are given 600 trials
which implies our x=600
Therefore, the number of times we would pick a green marble is:
2/5 × 600 times
≈ 240 times
Therefore, we would approximately pick a green marble 240 times
Answer:
4 1/10 ounces of Liquid plant fertilizer left
Step-by-step explanation:
Total quantity of Liquid plant fertilizer=6 3/5 ounces
Quantity used up on a flower garden=2 1/2 ounces
Quantity of liquid plant fertilizer are left=Total quantity of Liquid plant fertilizer -Quantity used up on a flower garden
6 3/5 ounces -2 1/2 ounces( subtract whole number from whole number and fraction from fraction)
6-2 3/5 - 1/2
4 (6-5) / 10
4 1/10 ounces of Liquid plant fertilizer left
