A cell phone company charges $15 for 120 minutes. What is the cost per minute? Round to the nearest cent.

Answers

Answer 1

Answer:

Answer: The cost per minute is $0.13 or 13 cents.

Step-by-step explanation:

If it charges $15 for 120 minutes then to get to one minute we will have to divide it by 120.

so 15/120 = 0.125 which rounds to 0.13 to the nearest cent.

Answer 2

The archaeological site of Tara is more than 4000 years old. Tradition states that Tara was the seat of the high kings of Ireland. Because of it's archaeological importance, Tara has received extensive study (Reference: Tara: An Archaeological Survey by Conor Newman, Royal Irish Academy, Dublin). Suppose an archaeologist wants to estimate the density of ferromagnetic artifacts in the Tara region. For this purpose, a random sample of 55 plots, each of size 100 square meters, is used. The number of ferromagnetic artifacts for each plot is determined.

Answers

Answer: Hello your question is incomplete attached below is the complete question.

answer:

a) The number of ferromagnetic artifacts per 100 square meters ( option A )

b) quantitative ( option D )

c) Entire Tara region ( option A )

Step-by-step explanation:

a) Determine The Variable

The number of ferromagnetic artifacts per 100 square meters

b) The Variable is quantitative

This is because the variable used in the study has numerical value attached to it hence we can say it is a quantitative variable.

c) The implied population

Entire Tara region

Use the steps to determine the exact value of sin(−135)°.

Identify the reference angle, θ.

θ =
°

Answers

To solve for sin(-135), the reference angle will be obtained as follow:
sin(-135)
=-sin(135)
=-sin(180-135)
=-sin 45
hence
the reference angle θ=45°

Answer:

The reference angle will be ${\theta}=45^(\circ)$

Step-by-step explanation:

To solve for $sin(-135)$ , the reference angle can be obtained as follows:

= $sin(-135)$

= $- sin(135)$ (Because $sin(-{\theta})=-sin{\theta}$ )

Thus, the above equation can be written as:

= $-sin(180-135)$

= $-sin45$

Hence, the reference angle will be ${\theta}=45^(\circ)$
