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.
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.

#SPJ1
The answer would be 300 since the 3 is in the hundreds place.
Answer:
80%
Step-by-step explanation:
First, you multiply 20 by 5, which gives you 100. Then multiply 16 by 5, which is 80. 80 out of 100 is 80%
Answer:
5x
Step-by-step explanation:
Given expression: 
Take the common number 5 outside in the numerator.
Now, take x common in both the terms in numerator.
Cancel out the common factor in the both numerator and denominator.
Hence, the answer is 5x.
This is because “trig” solves for the missing angles in a right angled triangle and does not solve for the sides of a right angle triangle.
Hope this helps :)
