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.
I think the first numerator cant be Z so I solved the question assuming it is 2;
Answer:
(x,y,z)=(1,5,7)
Hope this helps.
I feel it should be 30 because x represents the number of lessons, and 30 is multiplied by that.
Answer:
(this isnt a mathematics question, it's science, btw)
Indeed, you are correct. It is 1. I think.
Because you get one allele from each parent, to make up 2 alleles per offspring.
Hope that helps!
