Keep in mind the the word "percent" translates to "for each 100." 25% can be read as "25 for each 100," which has the fractional representation
and the decimal representation 0.25. All of these representations are just different ways of writing the same value.
Note too that the fraction
can be reduced to
, so what the question is really asking is: 1/4 of what number is 9?
Well, if we know that 1/4 of the number is 9, we can easily find how large the whole number is by finding all 4/4 of it (the <em>whole</em> number)<em /><em />, or 4 x 9, which multiplies out to
36.
Answer:
O is greater than -4
Step-by-step explanation:
Answer:
About 2614 years.
Step-by-step explanation:
We are given k, and the information that N/N0 = 0.77, so the C-14 function becomes:
and we can solve for t:
The estimated age of the bird skeleton is 2614 years.
Ans: Option (D) 25%
Explanation:
In this case you need to find the area under the curve, which would essentially be the probability of a value in the sample space.
Now the range given is from 60 to 80; it contains the mini-triangle.
The area of the triangle = (1/2)*base*height
Since base = 80 - 60 = 20
Height = 0.025 - 0 = 0.025 (see in the graph)
Therefore
The area of the triangle = 1/4 = 0.25 which is essentially be the probability.
In percentage form, it is 25% (Option D)
Answer:
<h2>1.C. Statistics</h2><h2>2.A. Analysis </h2><h2>3.D. organizations </h2><h2>4.B. sample</h2><h2>5.A. Census</h2>
Step-by-step explanation:
1.Statistics is a branch of mathematics dealing with data collection, organization, analysis, interpretation and presentation.
2.Scientists do this by collecting data, analyzing it and drawing a conclusion. The whole process, from forming a hypothesis to announcing conclusions, is called the scientific method.
3.organizations
4.A sample is a sub collection of elements drawn from a population
5.A census is the collection of data from every element in a population.
