Step-by-step explanation:
Answer:
NL = 4.33
NM = 5
Step-by-step explanation:
tan 60° = NL/2.5
tan 60° = 1.7321
so:
1.7321 = NL/2.5
NL = (2.5)(1.7321)
NL = 4.33
cos 60° = 2.5/NM
cos 60° = 0.5
so:
0.5 = 2.5.NM
NM = 2.5/0.5
NM = 5
2 miles should be the answer because 1/4x8=2
The answer to this question is the letter C:
-0.1*65 = -6.5
-6.5+110 + 103.5
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.
