Answer:
5
Step-by-step explanation:
The formula for Standard Error =
Standard deviation /√n
Where
n = Random number of samples
From the above question,
Standard deviation = 10
n = 4
Hence, Standard Error is calculated as:
= 10/√4
= 10/2
= 5
Therefore, the Standard error = 5
Answer:
D: 1.81
Step-by-step explanation:
For a percent you move the decimal place 2 places to the left, so if you move the decimal two places to the left in 1.81, you get 181 percent.
<h3>Explanation:</h3>
1. PQ║TS, PQ ≅ TS, PT and QS are transversals to the parallel lines . . . given
2. ∠P ≅ ∠T . . . alternate interior angles at PT
3. ∠Q ≅ ∠S . . . alternate interior angles at QS
4. ΔPQR ≅ ΔTSR . . . ASA postulate
_____
You can use any pair of angles together with the sides PQ and TS. If you use the vertical angles and one of ∠T or ∠S, then you must invoke the AAS postulate for congruence, as the side is not between the two angles.
Answer:
5.6
Step-by-step explanation:
if x is -1. multiply -0.6 * -1. Which is -0.6.
Then add -0.6 and 6.2 and the answer you would get is 5.6.
Answer:
Bottom= -2
Top= 3
Step-by-step explanation:
Since the bottom is 2 miles below the chair lift, you'd do 0-2 to get -2.
If the chair lift is 0 and we know the peak is 3 miles above it, you would add 3+0 to get 3.
