Probability of getting green or yellow marble is 7/20, getting blue is 1/4
7/20*1/4=7/80
Answer:
1024/59049
Step-by-step explanation:
P( clear hurdle) = 2/3
There are 10 hurdles
P ( clear all hurdles) = P( clear hurdle) * P( clear hurdle)...... 10 times
= 2/3 * 2/3 *....... 10 times
= (2/3) ^ 10
=1024/59049

O.
At room temperature, water will condense to form liquid water.
1 mole of methane reacts with 2 moles of oxygen to form 1 mole of oxygen.
10 ml (0.445 moles) of methane will react with 20 ml (0.89 moles) of oxygen to form 10 ml (0.445 moles) of carbon dioxide.
Hence, the resulting mixture will contain 10 ml of unreacted methane and 10 ml of carbon dioxide.
The total volume of the mixture will be 20 ml.
Step-by-step explanation:
For this case we can make the following rule of three:
2250 -----------> 100%
600 -------------> x
From here, we clear the value of x.
We have then:
Therefore, the decrease in percentage weight is:
Round to the nearest whole number:
x = 73%
Answer:
the percent decrease in the puppy's weight rounded to the nearest whole number is:
x = 73%
