Alla [95]

Answer:

B. Age of student

D. Time taken to run 1 mile

Step-by-step explanation:

From the list of given options, only B and D satisfy the required condition.

One unique determinant of continuous data is that; they are measured and not counted.

Now, let's categorize option A to D into two

1. Counted data

2. Measured data

Options that fall into the category of measured data are said to be continuous data.

A. Concert attendance; The number of people in a concert is counted

B. The age of a student is measured (in years)

C. Number of pens in a box is counted

D. Time taken to run 1 mile is measured (in units like seconds, minutes, hours, etc...)

In summary; we have

Counted

A. Concert Attendance

C. Number of pens in a box

Measured

B. Age of a student

D. Time taken to run 1 mile

Hence, the continuous data are Age of a student and Time taken to run 1 mile

Factor each expression.<br><br> (9) 5a - 25<br><br> (10) 28 - 7x<br><br> (11) 12z + 28 - 7z - 3
Nimfa-mama [501]

Answer:

Step-by-step explanation:

Look for the GCF and then divide every term by the GCF to see what remains

(9) 5a - 25  ( GCF is 5 so take out 5 and divide every term by 5)

     5(a-5)

(10) 28 - 7x     ( GCF is 7 so take out 7 and divide every term by 7)

     7(4-x)

(11) 12z + 28 - 7z - 3=  (combine terms) =

       5x+25( GCF is 5 so take out 5 and divide every term by 5)

        5(x+5)
