Answer:

14% probability of obtaining an interview with the next household on the sample list

Step-by-step explanation:

Cooperation rate of 14%

This means that the probability of someone at the contacted household agreeing to be interviewed is 14%, and the probability of a person agreeing to be interviewed in a household is independent of what happened in other households, that is, for each household, there is a 14% probability of obtaining an interview.

14% probability of obtaining an interview with the next household on the sample list

A parking garage allows users to park the first hour free and then charges $2.50 for each additional hour or fraction of an hour
Snowcat [4.5K]

The first hour is free, and the rest charges is $2.50


Let x be the time.

Let y be the total


Your equation will look like


When x < 2, y = 0

When x > 1, y = $2.50(x)


So:


1 < x < ∞ for hours, then equation will look like:

y = total amount

$2.50 is cost (remember that the first hour is for free, and so you subtract $2.50 from the total.


$2.50x - $2.50 = y should be your equation.


hope this helps

Haruka hiked several kilometers in the morning. She hiked only 666 kilometers in the afternoon, which was 25\%25%25, percent les
katen-ka-za [31]

Answer:

She hiked 1,554 kilometers in all.

Step-by-step explanation:

Let the hiking kilometers for morning be x

Given that:

Hiking kilometers in afternoon = 666

According to given condition that afternoon kilometers are 25% less than morning:

x = 666 + 25% of x

By simplifying:

x = 666 + 0.25x

x - 0.25x = 666

0.75x = 666

Dividing both sides by 0.75 we get:

x = 666/0.75

x = 888 kilometers

She hiked 888 kilometers in morning

And

Total = 888 + 666 =1554 km

i hope it will help you!
