Answer:
6
Step-by-step explanation:
So, 12 dimes is 120 cents. 120 cents is $1.20. You said he had 18 coins, and 12 dimes takes away 12 coins. So the only number left is 6. (I think)
Answer:
a) 
D. 9.74
b) 
B. 74
Step-by-step explanation:
Part a
We have the following dataset given:
69 74 75 62 70 93 64 69 61 88 67 77 87 90 66 91 77 63 82 82 71 74 76 65 83
We can begin calculating the sample mean with the following formula:
And replacing we got:
Now we can calculate the sample deviation with the following formula:
And after replace we got:
Part b
For this case we need to sort the value on increasing way:
[1] 61 62 63 64 65 66 67 69 69 70 71 74 74 75 76 77 77 82 82 83 87 88 90 91 93
And the median would be the value in the position 13 and we got:
Answer:
The interpretation of that same problem is listed throughout the section below on explanation.
Step-by-step explanation:
<u>Interpretation:</u>
- Researchers seem to be confident with 95% that the sample selection standard error seems to be + as well as - 4 percent respectively.
- This same margin of sampling error would then decrease from either the mean or average value by four percentage points smaller or even larger, it describes the survey method.
So that the above is the right answer.
73. you subtract 89 and 16 and that gives you your answer which is*** 73***
