Maël mixes 15 milliliter (mL) of bleach with 3.75 liters (L) of water to make a sanitizing solution for a daycare. The amounts o

You have not provided the options, therefore, I cannot give you an exact answer.
However, I will try to help you with the concept.

<u>First, we need to make all units the same in the problem. I will convert all units to ml.</u>
We have:
amount of bleach = 15 ml
amount of water = 3.75 liters = 3.75 * 1000 = 3750 ml

<u>Now, we will get the ratio between bleach and water:</u>
\frac{bleach}{water} =  \frac{15}{3750} =  \frac{1}{250}

<u>This ratio is fixed, therefore, to get the right choice:</u>
1- make all units the same
2- for each option, divide the amount of bleach by the amount of water.
The correct choice would be the one giving you \frac{1}{250}

Hope this helps :)

Emily wants to hang a painting in a gallery. The painting and frame must have an area of 31 square feet. The painting is 5 feet
seropon [69]
Area=legnth times width=31
the frame must go around the frame with equal legnth, x
so
the total area (meaning the frame +picture) is 5+x by 6+x
31=(5+x)(6+x)
expand
31=30+11x+x^2
minus 31 both sides
0=-1+11x+x^2
x^2+11x-1=0

answer is third one

Descriptive statistics are generally used for which of the following? Check all that apply. To make general conclusions about po
Tom [10]

Answer:

Correct answer is :

To simplify and summarize data

Step-by-step explanation:

Using sample data we can make inferences about a population using statistical methods such as linear regression. But descriptive statistics, as only describe general characteristics of a sample, can be not generalized to a larger population only by descriptive statistics.

Descriptive statistics (DS) can be used to describe dependent or dependent variables alike. If for example you want to predict the income of a person (dependent) in relation to age, education level ( independent) , descriptive statistics may be used to describe both type of variables the age of the sample or the levels of income.

DS are used basically to summarize data or to make it more simple to analyze.
