Answer:
In order to use all the paint in a paint mixture in the same ratio of 1:5, the painter needs 2.4 ounces of paint thinner
Explanation:
The given parameters are;
The number of parts of thinner used to create 5 parts of paint mixture = 1 part
The amount of paint the painter has = 12 ounces
The amount of thinner is given by the relation;
Ratio of thinner to paint mixture = 1:5
Which gives, 1 part of thinner is required for 5 parts of paint mixture
1/5 parts of thinner is required for 1 part of paint mixture
Therefore, 12/5 or 2.4 parts of thinner will be required for 12 parts of paint mixture
Which gives;
2.4 ounces of thinner will be required for 12 ounces of paint mixture
Therefore, in order to use all the paint in a paint mixture in the same ratio of 1:5, the painter needs 2.4 ounces of thinner.
I think it’s B
Hope it’s correct
The number of six samples that could belong to the same population is equivalent to six.
Option A is the correct answer.
<h3>What is the standard deviation?</h3>
The standard deviation is the indicator to determine the variation between the set of amounts as given in the statistical information.
The population is referred to as the entire information being prescribed in data relating to any concept. If the number of samples in a population is 10, then the samples in the same population will also be 10. This shows the number of samples is always equal to the samples in the same population.
Therefore, the six samples belong to the same population comprising of six samples having varied standard deviations.
