When graphing data, what will make it
more precise?
A. using larger units
B. making it cover most of the graph
C. using a bar graph
D. connecting all the points plotted

Answers

Answer:

A. using larger units

Explanation:

Graphs can be used to display large amounts of numerical data and to portray the relationships between numerical values of different variables

When graphing data, what will make it more precise would be to ensure that it covers most of the space on the graph sheet. The correct option would, therefore, be B.

Using larger units may result in inaccurate plotting of small variablesNot all data can be represented as a bar graphConnecting all the points plotted has no bearing on the precision of a graph

Making your graph to cover, at least, 2/3 of the graph space will ensure that your plots are visible and lead to a more precise graph.

HELP WILL GIVE BRAINLIEST IF CORRECT: What effect do plants' roots
have on rock?
a. They hold it together
b. They weather it
c. They cause it to undergo chemical changes
d. They break it apart

Answers

Answer: C

Explanation: Reason why is because whenever the roots put pressure on the rock it cracks open and all the minerals release so it has to be going thru a chemical change because the roots receive the minerals from the rock or stone ...

Answer:

im guessing d but im not sure..,

Explanation:

When these roots grow, they exert pressure on the rock around them, causing the gaps to widen or even crack. Plant roots can also weather rock through chemical processes. When dead roots decompose, they release carbon dioxide; this is sometimes converted into carbonic acid, which chemically breaks down rock into soil.

Explain and illustrate using chemical pathways how excessive alcohol intake can lead to; 1.Hypoglycemia

Answers

Answer: Alcohol can influence the blood sugar levels causing hypoglycemia.

Explanation:

Hypoglycemia is a condition in which the body experiences low blood sugar levels. Alcohol abuse can be one of the reasons for hypoglycemia. The occasional drinkers are affected negatively by this. It increases the secretion of insulin hormone which is a hormone necessary for keeping a balance of blood sugar levels in the body. The excess secretion of insulin can lead to decrease in blood sugar concentration and resulting in hypoglycemia. This can lead to type 1 diabetes.

In a population of 100 people, 30 have brown hair and 70 have black hair. What is the Relative Frequency for Black hair?

Answers

Answer:

0.7

Explanation:

Given that in statistics, the Relative Frequency is the Frequency of the class divided by Total.

Hence, in this case, the Relative Frequency of black hair is the Frequency of black hair divided by the Total.

Hence, we have 70 ÷ 100

=> 0.7

Therefore, the correct answer is 0.7 Relative frequency.
