Answer:
s ≈ 105
Step-by-step explanation:
<u>Given:</u>
- The data set: 700, 735, 680, 890, 755, 740, 670, 785, 805, 1050, 820, 750
<u>To find:</u>
- The standard deviation of the data
<u>Steps:</u>
To find the standard deviation, first write the computational formula for the standard deviation of the sample.

Take the square root of the answer found in step 7 above. This number is the standard deviation of the sample. It is symbolized by
. Here, we round the standard deviation to the nearest whole number.

Rounding to the nearest whole number:
s ≈ 105
Mes ∠AKG = mes ∠AKD + mes ∠ DKG
133° = mes ∠ AKD + 87°
133° - 87° = mes ∠AKD
∠AKD = 46°
Answer:
1,420 milligrams
Step-by-step explanation:
We know there are 100 centigrams in 1 gram, and there are 10 milligrams in a centigrams. That would mean there are 1,000 milligrams in 1 gram (100 * 10 = 1000).
As a result, all you need to do is multiply 1.42 by 1000 to get the amount of milligrams.
1.42 * 1000
Alternatively, to make 1.42 a whole number first, multiply by 100, then add a zero. (That's the other 10!)
(1.42 * 100) * 10
142 * 10
There are 1,420 milligrams in 1.42 grams.
