I'm confused too and I'm supposed to be an expert. I'm not entirely sure what frequency density is. We'll just treat this as a histogram.
Let's assume each five minute interval gives a value equal to or proportional to the number of people that finished in that interval.
From 0 to 50 we have 10 intervals; let's just make this into a table
0-5 0
5-10 40
10-15 40
15-20 30
20-25 30
25-30 25
30-35 25
35-40 25
40-45 25
45-50 15
From 0 to 40 that adds up to
0+40+40+30+30+25+25+25 = 215
From 0 to 50 that's
215+25+15 = 255
The fraction less than 40 is 215/255 = 43/51 ≈ .843
Answer: 84.3%
26 because 10 is less than 26 and so is 24
Answer:
Step-by-step explanation:
number 1 is 0.523
number 2 is 6.28
number 3 is 1.05
and 11pi/6 equals 5.8
please give me brainliest i double checked and got it right
So you know that the two sides have to be the same number so the two sides are 14 the other side is 7
