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%.

3y=24 solve by inspection
Ulleksa [173]

Explanation: Division property of equality is dividing both sides of an equation by the same non-zero number does not change the equation.

a÷c=b÷c for c≠0

<u><em>First, you divide by 3 both sides of an equation.</em></u>

<u><em>3y/3=24/3</em></u>

<u><em>Then, simplify.</em></u>

<u><em>24/3=8</em></u>

<u><em>8*3=24</em></u>

<u><em>24/8=3</em></u>

<u><em>y=8 is the final answer.</em></u>

<u><em>Hope this helps!</em></u>

<u><em>Thanks!</em></u>

<u><em>Have a great day!</em></u>

The sum of two consecutive integers is at least 185. what is the smaller of the two integers? enter your answer in the box.
ss7ja [257]
Let us assume the first integer to be = x
Then
The second integer will be = x + 1
The sum of the two consecutive integers =185
Then
x + x + 1 = 185
2x + 1 = 185
2x = 184
x = 92
From the above deduction, we can easily conclude that the smallest of the two integers is 92. I hope that the answer has helped you.

Which statement must be true? Two triangles placed side by side. Two sides each of the triangles are equal in length. The third
sladkih [1.3K]

It is impossible to determine the relationship between x and y from the question about the triangle. Hence,  the correct option is D. This is because none of the sides are labelled x or y from the information provided.

<h3>What are the relationships that exist between the sides of a triangle?</h3>

It is important to note that:

The side with the highest length is the side that is opposite the biggest angle.

It is also important to note that the angle that is least will always be opposite the side that is smallest.
