Artist 52 [7]3 years ago

3 0

Answer:

9 weeks

Step-by-step explanation:

If she took 10 quizzes over the span of 5 weeks, then she took 2 quizzes per week.

This is because:

10 quizzes ÷ 5 weeks = 2 quizzes

We can use this information to solve for 18 quizzes by setting up the equation the same way

If she takes 2 quizzes every week, and ends with 18 finished quizzes, how many total weeks did it take her ?

Variable x = total weeks

18 quizzes ÷ x weeks = 2 quizzes

With division, we can switch x weeks and 2 quizzes

18 quizzes ÷ 2 quizzes = x weeks

18 ÷ 2 = 9

9 weeks

Answer:

This is a biased sampling method for obtaining customer opinions because those who take the time to write an online review are likely to do so because they are upset with the service they received.
The direction of the bias is likely to overestimate the proportion of customers who have a negative opinion on the service.

Step-by-step explanation:

1) There are groups which are not represented in the survey like those who don't use web. And also those who take the time to write an online review are likely to do so because they are upset with the service they received.

2) Those who had negative experience are more likely to write a review than those who had not.

4+(x+y)=(4+ )+y please answer I need it now

Schach [20]

x=0

4+(x+y)=(4+)+y

4 + x + y = 4 + y

Subtract y from both sides

4 + x + y - y = 4 + y - y

Simplify

4 + x = 4

Subtract 4 from both sides

4 + x - 4 = 4 - 4

Simplify

x = 0

Which is the equation of the line with slope o passing through the point (-3, 6)?

harkovskaia [24]

Answer:

y = 6

Step-by-step explanation:

I'm assuming you are trying to say slope "0".

If the slope is 0, it means that the general equation Y = mX + c equals to Y = 0x + c and finally Y = c. Since the line is horizontal because it is 0 slope, Y = 6
