1.)Which two numbers on the number line have an absolute value of 1?
Naddik [55]

Absolute value is defined as the distance of a number from zero on a number line.

Since, the distance can never be negative, hence, absolute value can never be negative.

For example 1 is 1 away from the origin and -1 is also, 1 away from the origin.

Therefore, absolute value of both -1 and 1 is 1. Mathematically, we can write

|-1| =1

|1|=1

Therefore, the number 1 and -1 on the number line have an absolute value of 1.

Two cities A and B are 1400km apart and lie on the same N-S line. The latitude of city A is 23 Degrees. What is the latitude of
erica [24]

Answer:

{\theta}=12.53 degrees≈13degrees

Step-by-step explanation:

It is given that Two cities A and B are 1400km apart and lie on the same N-S line. The latitude of city A is 23 Degrees. Then,

Using the formula, S=r{\theta} where s is the distance between the two cities and r is the radius of the earth,thus substituting the values, we get

1400=6400{\theta}

⇒{\theta}=\frac{14}{64}

Therefore, {\theta}=\frac{14}{64}{\times}\frac{180^{{\circ}}}{{\pi}}

⇒{\theta}=\frac{2520}{200.96}

⇒{\theta}=12.53 degrees

Thus, the latitude of B is=12.53 degrees≈13degrees

Suppose that a company claims that its air fresheners last 23 days, on average. You take many large samples, and find, each time
Mice21 [21]
The answer is C 23. The problem says that "the mean number of days of the sample" is outside the confidence interval. The mean number of days of the sample is equal to 23. If 23 is outside the confidence interval, this is probably not the mean number of days that the company's air fresheners last.
