This is the "commutative property of addition." The order in which you add numbers together doesn't matter, and doesn't change your final results.
Given
49, 34, and 48 students are selected from the Sophomore, Junior, and Senior classes with 496, 348, and 481 students respectively.
To find:
Which of these types of sampling is used: random, stratified, systematic, cluster, convenience?
Explanation:
It is given that,
49, 34, and 48 students are selected from the Sophomore, Junior, and Senior classes with 496, 348, and 481 students respectively.
That implies,
Since Stratified random sampling is a method of sampling that involves dividing a population into smaller groups–called strata.
Then, the random sampling used is Stratified Random Sampling.
Step-by-step explanation:
I cant see the question but use the formula
y=mx+b
m=slope
b=y-intercept
you can also use the equation
y2-y1/x2-x1 to find slope.
since its a table, you can plug the x (input) and y (output) coordinates of the table to find the slope.
of students only saw jewelry collection
<em><u>Solution:</u></em>
Given that, On a class trip to the museum,5/8 of the students saw the dinosaurs
7/8 of the students saw either the jewelry collection or the dinosaurs
<em><u>To find: Fraction of students only saw jewelry collection</u></em>
From given statement,
Fraction of students saw dinosaur = 
Fraction of students saw either the jewelry collection or the dinosaurs = 
Therefore,
Fraction of students only saw jewelry collection = Fraction of students saw either the jewelry collection or the dinosaurs - Fraction of students saw dinosaur
Thus of students only saw jewelry collection
