Answer:

Option B.

Step-by-step explanation:

Consider the below figure attached with this question.

The given data set is 47, 48, 49, 50, 50, 53, 54, 54, 55, 56, 59, 61.

Class interval frequency table:

Intervals Numbers Frequency

45-49 47,48 2

49-52 49,50,50 3

52-56 53,54,54,55 4

56-60 56,59 2

60-64 61 1

Each histogram represent the frequencies on different intervals.

Frequencies on intervals 45-49, 49-52, 52-56, 56-60, 60-64 of given histogram are

Histogram A: 1, 2, 3, 1, 2

Histogram B: 2, 3, 4, 2, 1

Histogram C: 1, 3, 2, 1, 2

Histogram D: 5, 3, 2, 1, 2

Histogram B represents the given data set.

Therefore, the correct option is B.

Answer:

1. What is the y-intercept? y = 4

2. What is the maximum point? 4

3. What are the x-intercepts? (write the negative one first) x = -2 and x = 2

Step-by-step explanation:

In simple terms, the y-intercept is the part (s) where the graph hits the vertical line.

The maximum point is the highest point of the graph, coincidentally the maximum point on this graph is right on the y-intercept.

In simple terms, the x-intercept is the part (s) where the graph hits the horizontal line.

A ship traveled for 4 hours heading east and for 3 hours heading north. If the total distance traveled was 149 miles, and the sh

Alex

D=vt, distance is equal to velocity times time.

4v+3(v+3)=149 perform indicated multiplication

4v+3v+9=149 combine like terms on left side

7v+9=149 subtract 9 from both sides

7v=140 divide both sides by 7

v=20

So the ship traveled at a speed of 20 mph when heading east.

The question is incomplete. Here is the complete question.

The salary of members of two governing bodies in 2008 was $167.2 thousand, and has increased by approximately $2 thousand per year since then. Complete parts (a) and (b).

(a) Complete the following table to help find an expression that stands for the the salary (in thousands of dollars) of members of the two governing bodies t years since 2008.

Number of years and salaries of members of the two governing bodies

------------------------------------------------------------------------------------------------

Years since 2008 Salary (thousands of dollars)

------------------------------------------------------------------------------------------------

0 (2._) + ___

1 (2._) + ___

2 (2._) + ___

3 (2._) + ___

4 (2._) + ___

t ________

----------------------------------------------------------------------------------------------------

(b) Evaluate the expression that is found in part (a) for t = 5. What does the result means in this situation?

Answer: (a) The blank space inside the parenthesis is the number of years and the 2nd blank space is the salary: $167.2 thousand.

The last blank space is 2.t + 167.2.

(b) The value for t = 5 is 177.2 thousand.

Step-by-step explanation: The table in (a) is the description of the salaries per year. After 2008, there is an increase of 2000 per year.

Assuming t is in years, the expression for the salaries per year will be:

s = 2.t + 167.2

For part (b), t = 5. Substitute it into the equation, it is:

s = 2.t + 167.2

s = 2.5 + 167.2

s = 177.2

This means that in <u>year</u> <u>5</u>, the salary will be $ 177.2 thousand.
