Answer: C) 4.20
Explanation:
Multiply each value with its corresponding frequency:
- 1*450 = 450
- 10*35 = 350
- 50*10 = 500
- 100*4 = 400
- 400*1 = 400
Add up the products
450+350+500+400+400 = 2100
Then divide this over the total frequency (450+35+10+4+1 = 500)
So we get 2100/500 = 4.20 as the expected value.
The constant of proportionality is 4. Also, look at 36, and 9 because you could have just divided it it is not as complicated as you think.
7/19, 9/19 11/19
I hope this really helps
basically just add 2 on to the numerator
I need to see the diagram in order to answer your question.
Answer:
80
Step-by-step explanation:
720/P = 9/1
Cross multiply.
9P = 720
P = 720/9
P = 80
