Answer:
84.3%
Step-by-step explanation:
You first find the frequency. You do this by multiplying the frequency density by the class length.
Answer:70.8
Add up all the values in each 5 seconds up to 30, and divide by sum of all 50 seconds of frequency density and times by 100
x=7
2x-10=4 add 10 to both sides
2x=14 divide both sides by 2
The answer is J'(6, -2) M'(5,1)
if im correct it should be 40
