Answer:
A. 3 packs
B. $78.84
Step-by-step explanation:
A. Two bottles for each of 26 guests is a total of 2×26 = 52 bottles.
That many bottles will be found in 52/18 = 2 16/18 packs of bottles. Since Eliana cannot purchase partial packs, she will need to buy 3 packs of bottles.
__
B. Each pack costs $26.28, so the cost of 3 packs is 3×$26.28 = $78.84. Eliana will spend $78.84 on water for her guests.
Answer:
descriptive and inferential statistics.
Step-by-step explanation:
Science can be defined as a branch of intellectual and practical study which systematically observe a body of fact in relation to the structure and behavior of non-living and living organisms (animals, plants and humans) in the natural world through experiments.
In Statistics, sampling can be defined as a process used to collect or select data (objects, observations, or individuals) from a larger statistical population using specific procedures.
There are various types of sampling used by researchers and these are;
1. Random sampling.
2. Systematic sampling.
3. Stratified sampling.
4. Cluster sampling.
5. Opportunity or convenience sampling.
Focusing on describing or explaining data versus going beyond immediate data and making inferences is the difference between descriptive and inferential statistics because descriptive statistics focuses on describing or explaining data contained in a population or obtained as a sample while inferential statistics is solely based on drawing an inference from a sample or population.
Answer:
16
Step-by-step explanation:
The number to add on both sides to complete the square is the square of the numerical coefficient that accompanies the term in "x", divided by 2.
That is in our case: 
Therefore:
That way the left hand side of the equation becomes the perfect square of the binomial: (x+4).
You can also prove that such is correct by developing the square of the binomial:
