Answer:
A. Surveying every 25,000th number
Step-by-step explanation:
If the numbers of people are assigned in order of 1 to 1 000 000 then the smallest sample would be obtained by conducting surveys every 25 000th numbers.
The calculation of the sample size would be made by dividing 1 000 000 by 25 000.
Therefore, the smallest sample selected would be 40 people.
If the surveys were made every 25th numbers, then the sample size would be:
people
Answer:
x=34
Step-by-step explanation:
The angle measure of a straight line is 180 degrees.
So if you add up all of the angles to make an equation, you get 2x + 112=180.
Then solve.
2x + 112=180
-112
2x=68
x=34
You have 2 different questions on here but if you’re looking for 1/3x = 9 then x=27
Let's begin by identifying key information given to us:
Price sold: bike + accessories = $405
If he received 8 times as much money for the bike as he did for the accessories: bike = 8 * the accessories
Let "the accessories" be represented as y, "bike" be represented as x:
x = 8y
x = 8y
x = 8y
x = 8 * 45 = $360
Anthony purchased the bike for $360
