Answer:

A. more likely to roll a number greater than or equal to 3

Step-by-step explanation:

Take a look at the probabilities for each:

Greater than or equal to 3:

You can roll a 3, 4, 5, or 6

Less than 3:

You can roll a 1 or a 2.

To find probability, divide how many ways there are to get what you want by the number of total ways to get something at all.

For freater than or equal to 3:

You can roll a 3, 4, 5, or 6 to fulfill this, so 4 things that you want.

You could roll a 1, 2, 3, 4, 5, or 6 on this number cube, so 6 possibilities.

Divide 4 by 6, and you get 2/3.

For less than 3:

You can roll a 1 or a 2 to fulfill this, so 2 things you want.

Divide by 6 (again) total possibilities, and you get 1/3.

2/3 is more than 1/3, so the first possibility is more likely than the second.

The modal and mean mark of the frequency distribution is 5 and 4.83 respectively.

<h3>Mean and mode</h3>

Mode refers to a mark which reoccurs most in a frequency distribution.

  • Modal mark = 5

The total number of students who wrote the test = 2 + 3 + 4 + 6 + 10 + 4 + 3 + 2 + 1 + 1

= 36 students

Mean mark = Total mark / Total students

= (2×1) + (3×2) + (4×3) + (6×4) + (10×5) + (4×6) + (3×7) + (2×8) + (1×9) + (1×10) / 36

= (2+6+12+24+50+24+21+16+9+10 / 36

= 174/36

= 4.83333333333333

Approximately,

Mean mark = 4.83

If 25% of students failed,

Number of students who failed = 25% of 36

= 25/100 × 36

= 0.25 × 36

= 9 students.

What’s the answer to this
Setler [38]

Answer:

The answere is (9,3)

Step-by-step explanation:

first equation

x - 2y = 3

9 - 2(3) = 3

9-6 = 3

3 = 3

second equations

2x - 3y = 9

2(9) - 3(3) = 9

18 - 9 =9

9 = 9

or

x - 2y = 3

x = 2y + 3

2(2y + 3 ) - 3y = 9

4y +6 - 3y = 9

y + 6 = 9

y =3

x - 2(3) = 3

x - 6 =3

x = 9

so (9,3)

i hope this helpful
