Answer:
e. An online retailer reaches out only to its customers who have left positive reviews for its product and asks them to complete a survey of their experience with the retailer's products
Step-by-step explanation:
A sampling error happens when a sample has some kind of a bias.
One example is for example, sampling only members of one political party about a new bill.
In this question:
The correct answer is given by option e, because the retailer will have the opinions only from those with positive reviews, basically disconsidering those with negative reviews, and not giving them a clear idea of their service.
Answer:
A≈153.94mi²
Step-by-step explanation:
A = πr2 = π · 72 ≈ 153.93804mi²
Answer: B. False
Step-by-step explanation:
You assume the inverse of what you intend to prove is true, not the converse.
The possible integer values of n are:
-1, 0, 1 , 2 , and 3.
-1 to 3 are all greater than -2.
3 is the maximum since 3 is the greatest number where n is equal to it or lesser than it.
Solving the inequality: 3y - 4 > 17
3y - 4 > 17
Add 4 to both sides to move it.
3y > 17 + 4
3y > 21
Divide both sides by 3 to get the value of y.
3y/3 > 21
y > 7
The sign does not change since we did not divide or multiply by a negative.
Therefore, y is greater than 7.
For this case we have the following linear function:
What we must do is equal the function to zero or equivalently, substitute the value of y = 0 in the given function.
We have then:
From here, we clear the value of x.
We have then:
Answer:
all real zeros of the function y = 2x-4 are:
x = 2
