The confidence interval for the mean population of drivers who do not like driving at night is 57.79% - 62.21%.
<h3><u>Confidence interval</u></h3>
To determine what is the 92% confidence interval for the population mean of drivers that do not like driving at night, the following calculation must be performed:
- 1500 = 100
- 900 =X
- 900 x 100 / 1500 = X
- 60 = X
- 60 x 0.92 = 55.2
- 60 x 1.08 = 64.8
Therefore, the confidence interval for the mean population of drivers who do not like driving at night is 57.79% - 62.21%.

Answer:
The scale used on his map is <u>150 miles : 2 inches</u>.
Step-by-step explanation:
Given:
Ted knows the actual distance between two cities is 150 miles. His map shows a distance of 2 inches between these cities.
Now, to find the scale Ted used on his map.
The actual distance Ted know between two cities = 150 miles.
The distance on map between these cities = 2 inches.
So, to get the scale used on his map:
Therefore, the scale used on his map is 150 miles : 2 inches.
Refrection of (-20, 4) across x-axis gives (-20, 4) = (-20, -4)
Refrection of (-20, 4) across y-axis gives (20, 4)
Refrection of (-20, 4) across y = -x gives (20, -4)
Refrection of (-20, 4) across y = 7 gives (20, 10)
For the first is 3864
The second is 1320
A=3.14(which is pie) x 20.5^2
A=420x pie
A=1320
For the third is 2544
3864-1320=2544
Sorry if this is wrong too.
Answer:
z<8
Step-by-step explanation:
First: write down the equation : 6z<48
Second: divide both sides with 6 (since its the only number that can be divided for both sides)
Third: then you'll get z<8
