answer for this question is 3.85 units squared
Equation parallel to y = -x is y=-x+k
so 4.5 = -7 + k so k - 11.5
Equation is y = -x + 11.5
Answer: If element Q has 11 protons, its atomic <u>number</u> is 11.
Step-by-step explanation:
The atomic number of a chemical element is the total number of protons that each atom of that element has.
In other words: it indicates the amount of protons that is present in the nucleus of an atom.
In this sense, the periodic table of the elements arranges the chemical elements in the form of a table, ordered by their atomic number (number of protons), by their configuration of electrons and their chemical properties.
We know that
<span>4 1/2----------> (4*2+1)/2--------> 9/2
(2/3)*(9/2)------> 18/6--------->3 yd (</span><span>this is what Trisha has )</span>
<span>if she has (2/3) she only needs (1/3)
</span><span>
[</span>the minimum amount of fabric she must buy]=(9/2)*(1/3)=1.5 yd
the answer is
the minimum amount of fabric she must buy is 1.5 yd
In stratified sampling, a sample is drawn from each strata (using a random sampling method like simple random sampling or systematic sampling). In cluster sampling, the sampling unit is the whole cluster; Instead of sampling individuals from within each group, a researcher will study whole clusters.
