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

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

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

Can someone help me with this problem pls
GREYUIT [131]

Answer:

my answer was 7.5

Step-by-step explanation:

    2

2b+3b-10

4b+3b-10

10-7b=3b fraction bar means divide so...

3b

__                       2

4b because... b-2b=4b and 8-4b=4b

3/4 =7.5 because 4 cant go into three so you add a decimal and a zero and move decimal up and 4 can go into 30 7 time which equals 28 and 30-28 is 2 add another zero and its 20 and 4 goes in 5 times which equals 20 and 20-20=0 so its 7.5 (i hope this helps ;)
