PLEASE HELP Residents of Eastport are convinced about the number of drivers who speed when driving down Main street. A group of residents takes turns observing the street. Each person spends one hour how many drivers speed and how many obey the speed limit. What's the population being studied?
A. drivers who obey the speed limit
B. drivers who speed
C. drivers in Eastport
D. drivers who travel down the street

Answers

Answer: D

Step-by-step explanation:

The population being studied in this scenario is drivers who travel down the street. Option D: drivers who travel down the street, are the correct option as the residents are observing all the drivers that travel down Main Street, not just those who obey or break the speed limit. Therefore, all the drivers that use this street are the population being studied.

The first three terms of an arithmetic sequence are as follows.

Answers

Answer:

16,20

Step-by-step explanation:

As shown, you add four by each.

4+4=8

8+4=12

So, 12+4=16

16+4=20

Answer:

16 and 20

Step-by-step explanation:

In the arithmetic squence, we can tell that 4 is being added to each term.

Thus, we obtain the following rule:

4x  [Where "x" is the xth term]

To find the next two terms in the sequence, we need to determine the fourth and fifth term of the sequence. Let us substitute the "4" and "5" in the rule to determe the next two terms in the sequence.

Determining the 4th term of the sequence:

⇒ 4x

⇒ 4(4)

⇒ 16

Determining the 5th term of the sequence:

⇒ 4x

⇒ 4(5)

⇒ 20

Thus, the next two terms are 16 and 20.

What is Stem and leaf plot?

A stem-and-leaf plot is a graphical representation of data that organizes values into a format that displays both the individual data points and their corresponding frequency. It is a way to represent a set of numerical data visually.

To create a stem-and-leaf plot, we separate each number into a stem and a leaf. The stem represents the tens digit, and the leaf represents the ones digit.

Here is the completed stem-and-leaf plot for the given test grades:

4 | 2

6 | 7

7 | 3, 8, 8

8 | 2, 4, 6, 6

9 | 1, 4, 9

In this plot, the stem represents the tens digit, and the leaves represent the ones digit.

For example, the grade 73 is represented as 7 as the stem and 3 as the leaf. The grade 82 is represented as 8 as the stem and 2 as the leaf.
