Cos to 2 decimal places is -0.90
:)
Answer as a fraction = 2/3
Answer in decimal form = 0.667 (approximate)
=======================================================
Explanation:
The first thing we need is to find the mean. Add up the values to get 3+3+4+5+5+4 = 24. Then divide by n = 6 since there are 6 values.
24/n = 24/6 = 4
The mean is 4
Now subtract the mean from each value
- 3-4 = -1
- 3-4 = -1
- 4-4 = 0
- 5-4 = 1
- 5-4 = 1
- 4-4 = 0
Apply absolute value to each result so that the difference is not negative.
We get this new list: {1, 1, 0, 1, 1, 0}
Now compute the mean of that new list to get the final answer
1+1+0+1+1+0 = 4
4/n = 4/6 = 2/3 = 0.667 approximately
Answer:
m = -6
Step-by-step explanation:
3m = 2(m - 3)
Distribute
3m = 2m - 6
Subtract 2m from each side
3m -2m = 2m-2m -6
m = -6
Answer:
1/100
Step-by-step explanation:
7 in 3.47 is 7/100
7 in 7.34 is 7
so the first 7 is 1/100 times the value of 7
