Answer:
4.9 & 4.2
Step-by-step explanation:
First, we will have to define mode,
“Mode is the most frequently occurring value of the given data.”
The value with the greatest frequency is called mode. In order to find mode, we have to skim through the data. The value which is repeated most is the mode of the given data. A data can have more than one modes.
For the above data,
4.9 is repeated 3 times.
4.2 is repeated 3 times.
These both numbers have highest frequency in the data.
So the modes are 4.9 and 4.2 ..
Answer:
You distribute the 2xy and get
2xy(3xy + 5y - xy^2) = 6(x^2)(y^2) + 10xy^2 - 2(x^2)(y^3)
Answer:
18mL of the 20% solution must be mixed with 10 mL of the 6% solution to
obtain the desired 15% solution
Step-by-step explanation:
Ignore all of the useless information til the last sentence: How many milliliters of the 20% solution must be mixed with 10 mL of the 6% solution to obtain the desired 15% solution?
Our goal is to find out how many mL of 20% solution is needed to mix with 10mL of 6% solution to achive a 15% solution.
An easy and simple way to do it is to create a system of equation:
We add in x mL of 15% solution(Which has x mL of water and 20%*x mL of salt)
The equation: 15%=(20%x+0.6)/(x+10)
After solving it we get x=18
Therefore:
18mL of the 20% solution must be mixed with 10 mL of the 6% solution to
obtain the desired 15% solution
Hope this helps, have a good day!
