Answer:
f=11
Mode=4
Median=4
Explanation:
We are given that
a.Mean of the exam score,
=3.5
Score(x) frequency C.F
1 1 1
2 3 4
3 f 15(4+f=4+11)
4 13 28
5 4 32
Using the formula
b.Mode:The number which is repeat most times .
4 repeat most times
Hence, mode of all exam scores=4
N=32
N is even
Median=
5x-25=5, x=6; multiply the 5 times x and negative 5, then add 25 to both sides, and divide by 5 to get 6.
K = 70 i did 6 x -5 which was -30 then -30+100 = 70
Answer: C.
Step-by-step explanation:

▹ Answer
<em>4 ÷ 2/3 = 6</em>
<em>1 ÷ 10/3 = 3/10</em>
<em>1 ÷ 4/7 = 1 3/4</em>
<em>9 ÷ 1/3 = 27</em>
<em>4 ÷ 5/4 = 3 1/5</em>
▹ Step-by-Step Explanation
4 ÷ 2/3 = 4 × 3/2 = 12/2 = 6
1 ÷ 10/3 = 1 × 3/10 = 3/10
1 ÷ 4/7 = 1 × 7/4 = 7/4 = 1 3/4
9 ÷ 1/3 = 9 × 3/1 = 27/1 = 27
4 ÷ 5/4 = 4 × 4/5 = 16/5 = 3 1/5
Hope this helps!
